Ingersoll Rand 47701889001 Air Filter Element | Replaces 39708466 | 37–160 kW OEM

Product Overview

The 47701889001 is the intake air filter element for Ingersoll Rand screw air compressors. Its previous part number is 39708466, which is now discontinued in the Ingersoll Rand spare parts system and superseded by this 11-digit number. Both numbers refer to the same element, so you may still see old packaging or old lists marked 39708466.

This element sits inside the intake filter assembly, upstream of the airend inlet. As the compressor draws in outside air, dust, grit and fibers enter with it; the filter media stops these contaminants before they reach the rotors. It is the first filtration stage in the intake path, and its condition directly affects how long the downstream oil filter, oil separator and lubricant will last.

Coverage is wider than a typical air filter: from ML/MM/MH and MJ series 37–75 kW models, to XF/EP/HP/XP and SM/SL/SH series, and up to M75-2S through M160-2S two-stage compressors. One element serves five platforms and 45 models across 37–160 kW. Two other part numbers released in the same update, 47701890001 (previous 39903265) and 47701891001 (previous 39903281), share the same name but belong to different power ranges and are not interchangeable.

Technical Parameters

1. Filtration Performance

Parameter	Value / Notes
Filtration Rating	5–10 μm
Filtration Efficiency	≥98% for particles ≥5 μm
Filter Class	Characterized per ISO 5011 by efficiency, restriction and dust holding capacity; ventilation/AC grading (G4 / F5 / F7 etc.) does not apply
Dust Holding Capacity	Depends on site dust concentration; no single nominal value. Use intake differential pressure gauge reading as the criterion

Filtration rating and dust holding capacity should be read together. A filter with high efficiency but small dust space builds up restriction quickly and needs frequent replacement, raising total cost of ownership. This element's dimensions and pleat design target continuous duty on 37–160 kW compressors, retaining adequate dust space at 5–10 μm.

2. Flow and Restriction

Parameter	Value / Notes
Rated Air Flow	Must not be lower than compressor rated intake flow; this element covers 37–160 kW models with intake flow approx. 6–27 m³/min, based on nameplate discharge and corrected for intake temperature and altitude
Initial Pressure Drop	Approx. 0.3–0.5 kPa (clean, new element)
Operating Pressure Differential	Rises with dust loading; typical operating range approx. 0.5–1.5 kPa
Alarm / Final Restriction	Typical change threshold approx. 1.5–2.5 kPa; final criterion is the compressor intake vacuum / differential pressure gauge
Restriction vs. Energy	Each 1 kPa increase in intake restriction raises compression ratio by approx. 1% and compressor energy consumption by approx. 1.0%

Restriction-energy relationship (theoretical, based on compression ratio 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 change threshold, intake restriction can rise by more than 2 kPa, increasing energy consumption by about 2%. ML/MM/MH and M-2S series often run continuously, so this energy difference typically exceeds the filter price. Running by restriction, not by calendar, is the economical choice.

3. Dimensions and Installation

Parameter	Value / Notes
Outer Diameter	Approx. 278–280 mm
Inner Diameter	Approx. 156 mm
Total Height	Approx. 127–129 mm (including end caps)
Effective Filter Area	Depends on pleat count and depth; measure the old element
Pleat Count / Pitch	Varies by production batch and media configuration; count from the old element
Mounting Interface	Cylindrical insert type; secured by end cap compression inside the intake filter assembly
Sealing	Face seal; seal body integrated with or separate from end cap

Measurement checklist (recommended before ordering replacement):

Measurement	Notes
Outer Diameter	Outer edge of filter media
Inner Diameter	Center passage diameter
Total Height	Overall height including end caps
Seal Position and Type	Face / radial, and seal cross-section
Mounting Interface	Clamp, bolt hole or quick-fit type and dimensions

OD, ID, total height and seal type directly affect fit and bypass. Dimensions on this page are for initial comparison; please verify against the old element before formal purchase.

4. Material Construction

Component	Material	Notes
Filter Media	Wood pulp cellulose filter paper, pleated	Depth filtration; fibers capture particles in stages
Media Weight	Approx. 130 g/m²	Determines burst strength and dust space
Inner / Outer Support	Galvanized steel perforated cage	Double-sided support prevents media collapse under negative pressure
End Caps	Metal or polyurethane end caps	Bonded to media; also carries the seal
Seal	Nitrile rubber or polyurethane seal body	Prevents bypass between element and assembly
Adhesive	Polyurethane glue	Fixes and seals media to end caps and cage

5. Operating Tolerance

Parameter	Value / Notes
Operating Temperature	-10 °C to +80 °C
Relative Humidity	≤90% RH (non-condensing)
Burst / Collapse Pressure	Standard design withstands at least 5 kPa differential across media without deformation
Special Features	Wide power range intake filtration; pre-filter layer can be added in heavy dust to extend main element life

In high humidity, heavy dust or oil mist environments (textile, foundry, food, cement), media strength drops when wet and oil mist can cake the surface. Both conditions shorten actual life and require shorter inspection intervals.

6. Life and Maintenance

Parameter	Value / Notes
Service Life	2,000 hours or 3 months, whichever comes first
Heavy Dust Environment	Reduce hours accordingly (e.g. approx. 1,500 hours); calendar limit also moves up
Shelf Life	Use within 24 months; store dry, ventilated, away from light; avoid moisture and compression deformation
Replacement Criteria	Intake differential pressure gauge exceeds limit, or media shows damage, debonding, or flattened seal face

Both limits apply: 2,000 hours or 3 months, whichever comes first. The calendar limit exists because media absorbs moisture and ages over time; even if running hours are not reached, compressors with long shutdowns or intermittent duty still need timely replacement.

7. Standards

Standard	Notes
ISO 5011	Intake filter efficiency and dust holding capacity test method; basis for this type of air filter performance
GB/T 14295	Chinese national air filter standard, often referenced in domestic procurement and acceptance
ISO 8573-1	Compressed air quality classes, used to describe compressor supply air quality
Note	ISO 2941 / 2942 / 2943 / 3723 / 3724 series are hydraulic filter standards; ISO 16889 multi-pass method also applies to liquid filtration; EN 779 and its G4–F9 classes are for ventilation and AC filters. None apply to compressor intake filters and should not be used as performance basis

Installation and Maintenance Steps

Step 1: Confirm compressor status and spare parts. Check the nameplate model and power, confirm the new element matches the old part number (if the old one is marked 39708466, it is the same element). Prepare the new element, lint-free cloth and necessary tools.

Step 2: Shut down, depressurize, disconnect power. Follow shutdown procedure and wait for full depressurization. Disconnect main power and apply lockout/tagout. This is mandatory.

Step 3: Verify the old element before work. Before opening the intake filter assembly, read the part number stamped on the old element end cap and note its position. This element covers five platforms and 45 models across 37–160 kW, and some platforms have both primary and safety filters. This step prevents errors.

Step 4: Remove and inspect the old element. Lift out vertically and observe dust distribution and media condition. Criteria: if media is damaged, perforated, end caps debonded or seal face flattened, replace immediately even if interval not reached. If the outer surface has black oily sludge, intake oil mist is abnormal; inspect upstream environment.

Step 5: Clean the assembly interior. Wipe inner walls and bottom with lint-free cloth. Do not blow compressed air into the assembly, as this drives dust into the intake path. Criteria: no loose dust inside, seal face flat and clean.

Step 6: Install the new element. Install in the same orientation and position as the old one, paying attention to seal face direction and compression method. Criteria: element sits without play and seal face is evenly compressed around the circumference.

Step 7: Reassemble and confirm sealing. Refit cover or clamp and tighten evenly as required. Check that the intake vacuum gauge impulse line is clear—a blocked line gives a false clean reading and is a common source of misjudgment.

Step 8: Test run and record. Reset maintenance timer, start compressor at no load, observe intake vacuum gauge and running sound. Criteria: vacuum gauge stable within allowed range, no abnormal whistling (often indicates seal bypass). Record running hours at this change as the start of the next interval.

FAQ

Q1: Are 47701889001 and 39708466 the same part?

Yes. 39708466 is the previous Ingersoll Rand part number for this item. Ingersoll Rand switched a batch of M-series air filters from old numbers to new 11-digit numbers; 39708466 corresponds to 47701889001. The old number is marked "discontinued" in the current spare parts system. Old drawings and lists may show 39708466, but both numbers refer to the same element.

Q2: Can 47701889001 be interchanged with 47701890001 or 47701891001?

No. The three numbers belong to the same update batch and share the same name, but they cover different power ranges: this element covers 37–160 kW M-series and SM/SL/SH platforms, while the other two are for higher power models. Always verify against the part number stamped on the old element, not by name similarity.

Q3: Which models does this element fit?

Coverage is wider than typical air filters. See the model list in Section 6, grouped by platform. Typical examples include ML/MM/MH 37–75, XF/EP/HP/XP 50–100, SM/SL/SH series, and M75-2S to M160-2S two-stage models. If unsure, provide the compressor nameplate model and old element photos; we will cross-check by part number.

Q4: Why can one element cover such a wide power range?

Fit depends on the intake assembly interface and compressor restriction at rated intake flow, not solely on power. The intake assembly interface for this platform is common across 45 models from 37–160 kW, so one element serves three power bands. Larger models may use multiple elements per compressor; check quantity per unit before ordering.

Q5: What are the dimensions?

OD approx. 278–280 mm, ID approx. 156 mm, total height approx. 127–129 mm, net weight approx. 1.25 kg. Dimensions vary slightly by batch and media configuration. Before formal purchase, measure the old element or provide photos and nameplate; we will cross-check by part number.

Q6: What is the replacement interval?

Standard interval is 2,000 hours or 3 months, whichever comes first. In heavy dust environments (cement, quarry, mining, metalworking), reduce hours to approx. 1,500. Final criterion is the intake differential pressure gauge reading; replace when it exceeds the limit, regardless of running hours.

Q7: What happens if intake restriction rises?

First, energy consumption increases: each 1 kPa rise in intake restriction raises compression ratio by about 1% and energy use by about 1%. Second, intake flow drops, reducing discharge flow. Continuing past the change threshold saves less on the filter than the extra electricity cost, especially for continuous-duty compressors.

Q8: Can I use an alternative part?

Yes, but check three things: filtration rating, end cap seal type, and dimensions. If the seal type does not match the original, bypass can occur, sending unfiltered air to the airend and accelerating rotor and bearing wear. When sourcing alternatives, provide old element photos and this part number.

Q9: What if there is abnormal whistling after installation?

Whistling usually indicates seal bypass: element not fully seated, seal face deformed, or seal missing. Stop immediately and recheck: element seating, seal face for flattening or inversion. Also check the intake vacuum gauge impulse line for blockage to avoid misjudgment.

Q10: How to replace on two-stage intake systems?

If the intake assembly is two-stage (primary + safety filter), the two elements have different part numbers and positions and are not interchangeable. Replace in order from outside to inside, and verify each against the ordered part number. The safety filter is a backup for primary filter damage and should not be left unchanged just because it looks clean.

Q11: What are the storage requirements?

Store in a dry, ventilated, dark place; avoid moisture, rain and heavy compression. Moisture reduces media strength, and compression deforms the seal fit. Use within 24 months.

Adjacent platform comparison (to avoid wrong purchase; these are other part numbers and not interchangeable with this element):

Platform	Power Range	Air Filter Part Number	Notes
ML/MM/MH/MU 90–160	90–160 kW	39903291	Higher power platform, different part number
125S / 150S / 175S / 200S, M350-3S	90–160 kW	39903281	Higher power platform, different part number
M250 / ML250	Approx. 40 m³/min	39903265 / 42852129	Larger model platform, not interchangeable
Other two numbers in same update	—	47701890001, 47701891001	Same name, different power band, not interchangeable

Why verify by part number, not by compressor model. This element covers five platforms and a wide 37–160 kW range; within the same power band there may be different production batches and intake assembly configurations. Selection should be based first on the old element part number, second on the compressor nameplate, and third on installation position.

Three-Step Verification

1. Read the part number stamped on the old filter end cap or cage and compare with this number or previous 39708466 (same element, see Section 2);
2. Read the compressor nameplate model and confirm it is in the model list above;
3. Confirm the old element position (single-stage / two-stage, primary / safety) and quantity per unit.

If verification is still uncertain, provide compressor nameplate photo, old element photos (with stamped part number) and installation position notes. We will cross-check by part number before confirming.
