Product Overview
The 47701889001 is an intake air filter element for Ingersoll Rand oil-lubricated screw air compressors. Its previous part number is 39708466, which now shows as discontinued in the Ingersoll Rand spare parts system and has been superseded by this number. Older packaging and stock lists may still carry 39708466 — both numbers refer to the same filter element.
The element sits inside the intake filter assembly, upstream of the airend inlet. As the compressor draws in ambient air, dust, grit and fibres enter with it; the filter media traps these contaminants before they reach the rotors. As the first filtration stage in the intake path, its condition directly affects how long the downstream oil filter, oil separator and lubricant will last.
Coverage is wider than a typical compressor air filter: from ML/MM/MH and MJ series 37–75 kW units, through the XF/EP/HP/XP and SM/SL/SH series, to the two-stage M75-2S through M160-2S machines. One element serves five platforms and 45 models across the 37–160 kW range. Two other part numbers released in the same supersession batch — 47701890001 (previous PN 39903265) and 47701891001 (previous PN 39903281) — share the same description but belong to different power classes and are not interchangeable.

How to Confirm Fitment
A single machine may carry both a primary and a safety element — different positions, different part numbers. Before ordering, verify three points: (1) the part number stamped on the old element's end cap or frame matches this number or the previous PN 39708466; (2) the model on the machine nameplate appears in the model list in Section 6; (3) the old element's installation position and quantity per machine.
This element shares its description with 47701890001 and 47701891001 from the same supersession batch, but each belongs to a different power class. Always verify by part number — never order on the basis of a similar description or a similar machine rating.
Technical Specifications
1. Filtration Performance
| Parameter | Value / Notes |
|---|---|
| Filtration Rating | 5–10 μm |
| Filtration Efficiency | ≥98% (for particles ≥5 μm) |
| Filter Class | Characterised per ISO 5011 by efficiency, restriction and dust holding capacity; ventilation and air-conditioning classifications (G4 / F5 / F7 etc.) do not apply |
| Dust Holding Capacity | Directly related to on-site dust concentration; no universal nominal figure — use the intake differential pressure gauge reading as the criterion |
Filtration rating and dust holding capacity must be read together. An element with a fine rating but limited dust space builds restriction quickly and needs frequent replacement, raising total cost of ownership. The dimensions and pleat geometry of this element are designed for continuous duty on 37–160 kW machines, retaining adequate dust storage at 5–10 μm.
2. Flow and Restriction
| Parameter | Value / Notes |
|---|---|
| Rated Air Flow | Must be no lower than the machine's rated intake volume; this element covers 37–160 kW models with intake volumes of roughly 6–27 m³/min, calculated from nameplate discharge and corrected for intake temperature and altitude |
| Initial Pressure Drop | Approx. 0.3–0.5 kPa with a clean new element |
| Operating Differential Range | Rises progressively with dust loading; normal operating range approx. 0.5–1.5 kPa |
| Alarm / Final Restriction | Typical replacement threshold approx. 1.5–2.5 kPa; the intake vacuum / differential pressure gauge reading is the final criterion |
| Restriction vs. Energy | Each 1 kPa increase in intake restriction raises the compression ratio by about 1%, increasing machine energy consumption by about 1.0% |
Restriction vs. energy consumption (theoretical, at 0.85 MPa discharge gauge pressure)
| Intake Restriction | Compression Ratio | Energy Increase |
|---|---|---|
| 0 kPa (new element) | 9.39 | Baseline |
| 0.5 kPa | 9.44 | +0.5% |
| 1.0 kPa | 9.49 | +1.0% |
| 1.5 kPa | 9.53 | +1.5% |
| 2.0 kPa | 9.58 | +2.0% |
| 2.5 kPa | 9.63 | +2.5% |
From installation to the replacement threshold, intake restriction climbs by more than 2 kPa, adding roughly 2% to machine energy consumption. ML/MM/MH and M-2S series units typically run continuously, so this energy penalty usually exceeds the price of the element itself. Running past the restriction limit rather than the calendar limit is not economical.
3. Dimensions and Mounting
| Parameter | Value / Notes |
|---|---|
| Outer Diameter | Approx. 278–280 mm |
| Inner Diameter | Approx. 156 mm |
| Overall Height | Approx. 127–129 mm (including end caps) |
| Effective Filter Area | Depends on pleat count and depth; measure the unfolded dimensions of the old element |
| Pleat Count / Pitch | Varies by production batch and media configuration; count on the actual old element |
| Mounting Interface | Cylindrical push-in type; located and compressed by the end cap once seated in the intake filter assembly |
| Sealing | Face seal; seal body either moulded with the end cap or fitted separately |
Measurement checklist (recommended before ordering a replacement)
| Measurement | Notes |
|---|---|
| Outer diameter | Outer edge diameter of the filter media |
| Inner diameter | Diameter of the central passage |
| Overall height | Total height including end caps |
| Seal position and type | Face or radial, plus seal cross-section profile |
| Mounting interface | Type and dimensions of clamp, bolt holes or quick-fit structure |
Outer diameter, inner diameter, overall height and seal type determine whether the element seats correctly and whether bypass can occur. The dimensions on this page are for preliminary comparison; verify against the old element before placing a formal order.
4. Materials
| Component | Material | Notes |
|---|---|---|
| Filter Media | Wood-pulp cellulose filter paper, pleated construction | Depth filtration; fibre layers capture particles progressively |
| Media Grammage | Approx. 130 g/m² | Grammage determines burst strength and dust storage volume |
| Inner / Outer Support | Galvanised steel perforated cage | Double-sided support prevents media collapse under negative pressure |
| End Caps | Metal or polyurethane end caps | Bonded to the media and act as the seal carrier |
| Seal | Nitrile rubber or polyurethane seal body | Prevents bypass between element and assembly |
| Adhesive Layer | Polyurethane adhesive | Fixes and edge-seals the media to the end caps and cage |
5. Operating Environment
| Parameter | Value / Notes |
|---|---|
| Operating Temperature | -10 °C to +80 °C |
| Relative Humidity | ≤90% RH (non-condensing) |
| Burst / Collapse Resistance | Standard design withstands a cross-media differential of at least 5 kPa without deformation |
| Special Features | Wide power-range intake filtration; a pre-filter layer can be added in dusty sites to extend main element life |
Where machines run long-term in high-humidity, high-dust or oil-mist environments (textiles, foundries, food processing, cement plants), media strength drops once damp, and oil mist forms mud on the media surface. Both conditions shorten actual service life and require shorter inspection intervals.
6. Service Life and Maintenance
| Parameter | Value / Notes |
|---|---|
| Service Life | 2000 hours or 3 months, whichever comes first |
| High-Dust Environments | Reduce hours accordingly (e.g. approx. 1500 hours), with the calendar limit brought forward as well |
| Shelf Life | Use within 24 months; store dry, ventilated and out of direct light, protected from moisture and compression |
| Replacement Criteria | Intake differential pressure gauge reading over limit, or media damage, adhesive failure, or a flattened seal face |
The "2000 hours or 3 months" limits apply simultaneously — whichever comes first. The calendar limit exists because media absorbs moisture and ages over time; even if operating hours have not been reached, machines that sit idle or run intermittently still need scheduled replacement.
7. Applicable Standards
| Standard | Notes |
|---|---|
| ISO 5011 | Test method for intake filter efficiency and dust holding capacity; the basis for performance characterisation of this type of air filter |
| GB/T 14295 | National air filter standard, commonly referenced for domestic procurement and acceptance |
| ISO 8573-1 | Compressed air quality classes, used to describe the machine's overall air supply quality |
| Note | The ISO 2941 / 2942 / 2943 / 3723 / 3724 series often cited for replacement parts are hydraulic filter standards; ISO 16889 multi-pass testing also applies to liquid filtration; EN 779 and its G4–F9 classes belong to the ventilation and air-conditioning filter system. None of these three applies to compressor intake filter elements and should not be used as performance criteria for air filters. |
Standard Maintenance and Installation Procedure
Step 1: Confirm machine status and spare parts. Check the nameplate model and power rating, and confirm the element matches the old part number (if the old element is stamped 39708466, it is the same part as this number). Have the new element, lint-free cloths and necessary tools ready.
Step 2: Shut down, depressurise, isolate power. Follow the shutdown procedure and allow the machine to fully depressurise. Isolate the main power supply and apply lockout/tagout. This step is mandatory.
Step 3: Verify the old element before starting work. Before opening the intake filter assembly, read the stamped part number on the old element's end cap and note its installation position. This element covers five platforms and 45 models from 37–160 kW, and some platforms use both a primary and a safety element — this step is the key safeguard against error.
Step 4: Remove and assess the old element. Lift the old element out vertically and inspect dust distribution and media condition. Criteria: if the media is torn, perforated, the end cap has debonded, or the seal face is flattened, replace immediately even if the interval has not been reached. If the outer surface carries black oily sludge, intake oil mist is abnormal and the upstream environment needs investigation.
Step 5: Clean the assembly interior. Wipe the inner walls and base with a lint-free cloth. Never blow compressed air directly into the assembly — this drives dust into the intake duct. Criteria: no loose dust on the inner walls, seal face flat and free of debris.
Step 6: Fit the new element. Install in the same orientation and position as the old element, noting seal face direction and compression method. Criteria: no movement once seated, and even circumferential compression on the seal face.
Step 7: Reassemble and confirm sealing. Refit the cover or clamp and tighten evenly as specified. Check that the intake vacuum gauge impulse line is clear — a blocked impulse line gives a falsely "clean" reading and is a common source of misjudgement.
Step 8: Test run and record. Reset the service timer, start the machine unloaded and observe the intake vacuum gauge reading and running sound. Criteria: gauge stable within the machine's permitted range, no abnormal whistling (whistling usually indicates seal bypass). Record the operating hours at replacement as the starting point for the next interval.
Frequently Asked Questions
Q1: Are 47701889001 and 39708466 the same part?
Yes. 39708466 is the previous part number for this item. Ingersoll Rand migrated a batch of M series air filters from older numbers to 11-digit numbers, and the new number corresponding to 39708466 is 47701889001. The old number now shows as discontinued in the current spare parts system. Old drawings and spare parts lists may still show 39708466 — they refer to the same filter element.
Q2: Can 47701889001 be interchanged with 47701890001 or 47701891001?
No. All three numbers belong to the same supersession batch and share the same description as air filter elements, but each corresponds to a different power class intake configuration. This element covers the 37–160 kW M series and the SM/SL/SH platforms; the other two serve higher power classes. Verify against the stamped part number on the old element — do not order on the basis of a similar description.
Q3: Which machine models does this element fit?
Coverage is wider than a typical air filter. The model list is grouped by platform in Section 6. Typical examples include ML/MM/MH 37–75, XF/EP/HP/XP 50–100, the SM/SL/SH series, and the two-stage M75-2S through M160-2S models. If unsure, provide the machine nameplate model and a photo of the old element, and we will cross-reference by part number.
Q4: Why can one element cover such a wide power range?
Fitment depends on the intake assembly interface and the machine's restriction at rated intake volume, not on power alone. The intake assembly interface used by this element's platforms is common across 45 models from 37–160 kW, so one element serves three power classes. Higher-power models may use more than one element per machine — confirm the quantity for your unit before ordering.
Q5: What are the dimensions?
Outer diameter approx. 278–280 mm, inner diameter approx. 156 mm, overall height approx. 127–129 mm, reference net weight approx. 1.25 kg. Dimensions vary slightly by production batch and media configuration. Before ordering, measure the old element or provide photos of the old element and the machine nameplate for cross-reference.
Q6: What is the replacement interval?
The standard interval is 2000 hours or 3 months, whichever comes first. In high-dust environments (cement, quarrying, mining, metalworking), reduce the hours to approximately 1500. The intake differential pressure gauge reading is the final criterion — replace once it exceeds the limit, regardless of operating hours.
Q7: What happens when intake restriction rises?
Two effects: energy consumption rises — each 1 kPa of additional intake restriction raises the compression ratio by about 1% and machine energy consumption by about 1%; and intake volume falls, reducing discharge volume. Running past the replacement threshold costs more in electricity than the element itself. This is especially pronounced on continuously running machines.
Q8: Can alternative elements be used?
Yes, but verify three things: filtration rating, end cap seal type, and dimensions. An alternative with a seal type that does not match the original structure will bypass, sending unfiltered air straight to the airend and accelerating rotor and bearing wear. When sourcing alternatives, provide a photo of the old element and this part number.
Q9: What should I do if there is abnormal whistling after installation?
Whistling usually indicates seal bypass — the element is not fully seated, the seal face is deformed, or the seal is missing. Stop the machine immediately and recheck: element seating, and whether the seal face is flattened or rolled. Also check whether the intake vacuum gauge impulse line is blocked to avoid misdiagnosis.
Q10: How do I replace elements on a two-stage intake system?
Where the intake assembly has two stages (primary and safety), the two elements have different part numbers and positions and are not interchangeable. Replace outside-in and verify each stage against the ordered part number. The safety element is a backstop if the primary fails and should not be left in service long-term because it "looks clean".
Q11: Are there storage requirements for spare parts?
Store in a dry, ventilated place out of direct light, protected from moisture, rain and heavy compression. Damp media loses strength, and compression deformation damages the sealing fit. Use within 24 months.

Why you must verify by part number rather than by machine model
This element covers five platforms across a wide 37–160 kW range, and the same power class may include different production batches and intake assembly configurations. Select parts based on the old element's stamped part number first, the machine nameplate second, and the installation position third.
Three-Step Verification
- Read the stamped part number on the old element's end cap or frame and compare it with this number or the previous PN (the previous PN is the same part — see Section 2 for the correspondence);
- Read the model on the machine nameplate and confirm it appears in the model list in this section;
- Confirm the old element's installation position (single-stage / two-stage, primary / safety) and quantity per machine.
If these three steps do not confirm fitment, provide a photo of the machine nameplate, a photo of the old element (including the stamped part number) and a description of the installation position, and we will cross-reference by part number.
Related Components
Components typically maintained on the same machines and the same cycle:
| Component | Part Number | Function | Inspection Points |
|---|---|---|---|
| Oil Filter Element | 39911631 | Removes wear debris and sludge from lubricant, protecting rotors and bearings | Check alongside the air filter; replace per the machine manual interval |
| Oil Filter Assembly | 39259668 | Housing assembly carrying the oil filter element | Check seal face and mounting seat for leaks |
| Oil Separator Element | 54601513 | Separates oil mist from compressed air and returns oil, controlling discharge oil carryover | Check the oil return line for blockage at replacement |
| Lubricant (Ultra Coolant) | 38459582 | Standard Ingersoll Rand screw compressor coolant, providing lubrication and sealing | Test oil condition per machine requirements; avoid mixing with other grades |
| Air Filter Housing | 39911458 | Housing assembly that holds and locates the intake filter element | Check clamps, seal faces and outlet end for deformation or corrosion |
| Air Filter Housing Cover | 39911359 | Closes the intake housing and compresses the element end face | Check seal face flatness and that all fasteners are present |
| Safety Element (two-stage intake) | — | Backstop if the primary element fails, preventing unfiltered air from reaching the airend | Check alongside the primary; do not leave in service long-term because it looks clean |
| Intake Differential Pressure / Vacuum Gauge | — | Shows intake restriction and is the final criterion for replacement | Check the impulse line regularly for blockage, which gives a falsely "clean" reading |
Recommended combined replacement: the air filter, oil filter element and oil separator element share the 2000-hour interval. Replacing them together avoids staggered maintenance cycles. In dusty sites, add a high-dust pre-filter layer first — pre-filter cost is far lower than the main element and replacement is faster.
For specific part numbers: items marked "—" above should be taken from the machine's own parts manual. This element covers five platforms, so companion part numbers must match your machine model and should not be applied across platforms.
