Product Overview
Part number 47701889001 is the intake air filter element for Ingersoll Rand screw air compressors. It replaces the previous OEM part number 39708466, which now carries "obsolete" status in the Ingersoll Rand spare parts system. Old packaging and legacy parts lists may still show 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 are captured 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 broader than a typical air filter: from ML/MM/MH and MJ series 37–75 kW units, through XF/EP/HP/XP and SM/SL/SH series, to M75-2S through M160-2S two-stage models. One element serves 45 models across five platforms in the 37–160 kW range. Two other part numbers released in the same changeover — 47701890001 (previous 39903265) and 47701891001 (previous 39903281) — share the same description but belong to different power bands and are not interchangeable.
Core Specifications

| Description | Air Filter Element |
| Brand | Ingersoll Rand |
| Power Coverage | 37–160 kW |
| Filtration Rating | 5–10 μm |
| Filtration Efficiency | ≥98% (for particles ≥5 μm) |
| Dimensions | OD approx. 278–280 mm, ID approx. 156 mm, overall height approx. 127–129 mm |

Technical Parameters
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; HVAC classification systems (G4 / F5 / F7) do not apply |
| Dust Holding Capacity | Directly related to site dust concentration; no universal nominal value — use intake differential pressure gauge readings as the criterion |
Filtration rating and dust holding capacity must be read together. A filter with high rating but limited dust space will build restriction quickly and require frequent replacement, raising total cost of ownership. This element's dimensions and pleat geometry are designed for continuous-duty 37–160 kW machines, retaining adequate dust capacity at 5–10 μm.
2. Flow and Restriction
| Parameter | Value / Notes |
|---|---|
| Rated Air Flow | Must not be below the compressor's rated intake volume; this element covers 37–160 kW models with intake volumes of approximately 6–27 m³/min — check the unit nameplate capacity and apply corrections for intake temperature and altitude |
| Initial Pressure Drop | Approx. 0.3–0.5 kPa (clean element) |
| Operating Differential Range | Rises progressively with dust loading; typical 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 approx. 1%, increasing compressor energy consumption by approx. 1.0% |
Restriction vs. energy consumption (theoretical compression ratio calculation, 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 rises by more than 2 kPa, increasing compressor energy consumption by approximately 2%. 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 to save on filter cost is not economical.
3. Dimensions and Installation
| 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 | Determined by pleat count and depth; measure the removed element for reference |
| Pleat Count / Spacing | Varies by production batch and media configuration; verify against the removed element |
| Mounting Interface | Cylindrical push-in type; secured by end cap compression inside the intake filter assembly |
| Sealing | Face seal; sealing body either integrated with the end cap or fitted separately |
Recommended measurements before ordering a replacement:
| Measurement | Notes |
|---|---|
| Outer Diameter | Outer edge of the filter media |
| Inner Diameter | Centre passage diameter |
| Overall Height | Including end caps |
| Seal Position and Type | Face / radial, plus seal cross-section profile |
| Mounting Interface | Clamp, bolt hole or quick-fit configuration and dimensions |
Outer diameter, inner diameter, overall height and seal type all determine whether the element fits and whether bypass occurs. Dimensions on this page are for preliminary comparison — verify against the removed element before placing an order.
4. Construction Materials
| Component | Material | Notes |
|---|---|---|
| Filter Media | Wood pulp cellulose filter paper, pleated | Depth filtration; fibres capture particles progressively |
| Media Grammage | Approx. 130 g/m² | Determines burst strength and dust holding space |
| Inner / Outer Support | Galvanised steel perforated cage | Double-sided support prevents media collapse under vacuum |
| End Caps | Metal or polyurethane end caps | Bonded to media; also serve as seal carrier |
| Seal | Nitrile rubber or polyurethane seal body | Prevents bypass between element and assembly |
| Bonding Layer | Polyurethane adhesive | Fixes and seals media to end caps and cage |
5. Operating Conditions
| Parameter | Value / Notes |
|---|---|
| Operating Temperature | -10 °C to +80 °C |
| Relative Humidity | ≤90% RH (non-condensing) |
| Burst / Collapse Pressure | Standard design withstands ≥5 kPa across the media without deformation |
| Special Features | Wide power-band intake filtration; pre-filter layer can be added in high-dust environments to extend main element life |
Units running long-term in high-humidity, high-dust or oil-mist environments (textiles, foundries, food processing, cement) will see reduced media strength from moisture and surface caking from oil mist. 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 Environment | Reduce hours accordingly (e.g. approx. 1500 hours); bring the calendar limit forward as well |
| Shelf Life | Use within 24 months; store in a dry, ventilated, dark location, protected from moisture and compression |
| Replacement Criteria | Intake differential pressure gauge reading exceeds limit, or media shows damage, debonding or a compressed seal face |
Both limits — 2000 hours and 3 months — apply, whichever comes first. The calendar limit exists because media absorbs moisture and ages over time; even if running hours have not been reached, units on extended standby or intermittent duty still require periodic replacement.
7. Applicable Standards
| Standard | Notes |
|---|---|
| ISO 5011 | Intake filter efficiency and dust holding capacity test method; the basis for performance characterisation of this type of air filter element |
| GB/T 14295 | National air filter standard, commonly referenced in domestic procurement and acceptance |
| ISO 8573-1 | Compressed air quality classes, used to describe the complete compressor's air supply grade |
| Note | ISO 2941 / 2942 / 2943 / 3723 / 3724 series and ISO 16889 multi-pass are hydraulic and liquid filtration standards; EN 779 and its G4–F9 classes apply to HVAC filters. None of these three families apply to compressor intake elements and should not be used as air filter performance references. |
Installation and Maintenance Steps
Step 1: Confirm unit status and spare part. Check the unit nameplate model and power rating, and confirm the new element matches the old part number (if the old element is marked 39708466, it is the same part). 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 unit to fully depressurise. Disconnect 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 part number stamped on the old element's end cap and note its installation position. This element covers 45 models across five platforms in the 37–160 kW range, and some platforms use both a primary and a safety element — this step is the key error-prevention check.
Step 4: Remove and assess the old element. Lift the old element out vertically and inspect dust distribution and media condition. Criteria: replace immediately if the media is torn, perforated, debonded from the end cap or has a compressed seal face — even if the service interval has not been reached. Black oily sludge on the outer surface indicates abnormal oil mist in the intake; inspect the upstream environment.
Step 5: Clean the assembly interior. Wipe the inner walls and base with a lint-free cloth. Do not blow compressed air into the assembly — this drives dust into the intake passage. Criteria: no loose dust on inner walls, seal face flat and free of debris.
Step 6: Install the new element. Fit the new element in the same orientation and position as the old one, noting seal face direction and compression method. Criteria: no movement once seated, seal face evenly compressed around its circumference.
Step 7: Refit and confirm sealing. Replace the cover or clamp and tighten evenly per unit requirements. Check that the intake vacuum gauge impulse line is clear — a blocked impulse line gives a falsely clean reading, a common source of misdiagnosis.
Step 8: Test run and record. Reset the maintenance timer, start the unit at no load, and observe the intake vacuum gauge reading and running sound. Criteria: gauge stable within the unit's permitted range, no abnormal whistling (whistling usually indicates seal bypass). Record the running hours at replacement as the starting point for the next interval.
FAQ
Q1: Are 47701889001 and 39708466 the same part?
Yes. 39708466 is the previous OEM number for this part. Ingersoll Rand migrated a batch of M series air filters from legacy numbers to 11-digit numbers, and 39708466 corresponds to 47701889001. The old number now carries obsolete status in the current spare parts system. Legacy drawings and parts lists may show 39708466 — both numbers refer to the same filter element.
Q2: Can 47701889001, 47701890001 and 47701891001 be used interchangeably?
No. All three numbers come from the same changeover batch and share the same description, but they serve different power bands. This element covers 37–160 kW M series and SM/SL/SH platforms; the other two serve higher power bands. Verify against the part number stamped on the old element — do not order based on similar descriptions.
Q3: Which compressor models does this element fit?
Coverage is broader than a typical air filter. See the model list below, grouped by platform. Typical examples include ML/MM/MH 37–75, XF/EP/HP/XP 50–100, SM/SL/SH series, and M75-2S through M160-2S two-stage models. If unsure, provide the unit 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?
Element fitment depends on the intake assembly interface and the machine's restriction at rated intake volume, not on power alone. The intake assembly interface for this platform is common across 45 models from 37–160 kW, so the same element is used across three power bands. Higher-power models may use multiple elements per unit — confirm the quantity for your machine 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. Measure the old element before ordering, or provide photos and the unit nameplate for cross-reference.
Q6: What is the replacement interval?
Standard interval is 2000 hours or 3 months, whichever comes first. In high-dust environments (cement, quarrying, mining, metalworking) reduce hours to approximately 1500. The intake differential pressure gauge reading is the final criterion — replace when the reading exceeds the limit, regardless of running hours.
Q7: What happens when intake restriction rises?
First, energy consumption increases: each 1 kPa of additional intake restriction raises the compression ratio by approx. 1% and energy consumption by approx. 1%. Second, intake volume drops, reducing compressor output. Continuing to run past the replacement threshold costs more in electricity than the element itself. The effect is especially pronounced on continuously running units.
Q8: Can aftermarket alternatives be used?
Yes, but verify three things: filtration rating, end cap seal type, and dimensions. If the seal type does not match the original structure, bypass occurs and unfiltered air enters the airend, 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 unit immediately and recheck: is the element seated, is the seal face compressed 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?
If the intake assembly is two-stage (primary plus safety element), the two elements have different part numbers and positions and are not interchangeable. Replace outside-in and verify each element against its part number. The safety element protects the airend if the primary fails and should not be left in service indefinitely because it "looks clean".
Q11: What are the storage requirements?
Store in a dry, ventilated, dark location, protected from moisture, rain and heavy compression. Moisture reduces media strength; compression deforms the seal 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 different production batches or intake assembly configurations can exist within the same power band. Selection should be based first on the part number stamped on the old element, second on the unit nameplate, and third on installation position.
Three-Step Verification
- Read the part number stamped on the old element's end cap or cage and compare with this part number or the previous number 39708466 (same part — see Section 2);
- Read the unit nameplate model and confirm it appears in the model list above;
- Confirm the old element's installation position (single-stage / two-stage, primary / safety) and quantity per unit.
If verification is still inconclusive after these three steps, provide a photo of the unit nameplate, a photo of the old element (including the stamped part number) and a note on installation position, and we will cross-reference by part number.

Recommended combined replacement: air filter, oil filter and oil separator share the 2000-hour interval. Replacing them together avoids staggered maintenance cycles. In dusty sites, fit a high-dust pre-filter layer first — pre-filter cost is far below that of the main element and replacement is faster.
For specific part numbers: items marked "—" above should be confirmed against the machine's parts manual. This element covers five platforms, and associated part numbers must match the specific machine model — do not apply across platforms.
