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

Product Overview

Part number 47701889001 is the inlet air filter element for Ingersoll Rand screw air compressors, replacing the previous part number 39708466. The old number is now marked as discontinued in the Ingersoll Rand spare parts system and is superseded by this new 11-digit number. Both numbers refer to the same filter element; old packaging and bills of materials may still list 39708466.

This element is installed inside the compressor's air intake filter assembly, upstream of the airend inlet. It is the first filtration stage on the intake path, protecting the rotors, bearings, oil filter, separator element and lubricant from dust, sand and fibers drawn in from the environment.

The element covers a wide range: from ML/MM/MH and MJ series 37–75 kW units, through XF/EP/HP/XP and SM/SL/SH series, up to M75-2S to M160-2S two-stage compressors. A single element serves 45 models across five platforms from 37 to 160 kW. Two other part numbers released in the same changeover—47701890001 (old 39903265) and 47701891001 (old 39903281)—share the same name but belong to different power ranges and are not interchangeable.

Technical Parameters

Filtration Performance

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

Filtration rating and dust holding capacity must be considered together. A filter with high efficiency but small dust capacity will clog quickly, causing frequent replacements and higher total cost of ownership. This element's dimensions and pleat design are optimized for continuous duty on 37–160 kW compressors, balancing 5–10 μm filtration with sufficient dust storage.

Flow and Pressure Drop

Parameter	Value / Note
Rated Air Flow	Must not be less than compressor rated intake flow; covers 37–160 kW models with intake flows approx. 6–27 m³/min. Refer to compressor nameplate and correct for inlet temperature and altitude.
Initial Pressure Drop	Approx. 0.3–0.5 kPa (clean element)
Operating Pressure Drop Range	Gradually increases with dust loading; typical range 0.5–1.5 kPa
Alarm / Final Resistance	Typical replacement threshold approx. 1.5–2.5 kPa; always confirm with intake vacuum/differential pressure gauge
Pressure Drop vs. Energy	Each 1 kPa increase in intake resistance raises compression ratio by approx. 1% and compressor energy consumption by approx. 1.0%

Pressure drop vs. energy consumption (theoretical, at 0.85 MPa discharge gauge pressure)

Intake Resistance	Compression Ratio	Energy Increase
0 kPa (new)	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 reaching the replacement threshold, intake resistance typically rises by over 2 kPa, increasing energy consumption by about 2%. ML/MM/MH and M-2S series often run continuously; the energy penalty usually exceeds the filter price, so extending service beyond the pressure drop limit is not economical.

Dimensions and Installation

Parameter	Value / Note
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 from old element
Pleat Count / Spacing	Varies by production batch and media configuration; verify with old element
Mounting Interface	Cylindrical insert type; secured by end cap compression inside intake filter assembly
Sealing	Face seal; seal body integrated with end cap or separate

Recommended measurements before ordering a replacement

Measurement	Note
Outer Diameter	Outer edge of filter media
Inner Diameter	Center tube diameter
Overall Height	Including end caps
Sealing Surface Position & Type	Face or radial; seal cross-section
Mounting Interface	Clamp, bolt holes or quick-connect type and dimensions

Outer diameter, inner diameter, overall height and sealing type all affect fit and bypass. Dimensions on this page are for preliminary comparison; always verify against the old element before purchase.

Materials of Construction

Component	Material	Note
Filter Media	Cellulose fiber paper, pleated	Depth filtration, particles captured progressively through fiber layers
Media Weight	Approx. 130 g/m²	Determines burst strength and dust holding capacity
Inner/Outer Support	Galvanized steel perforated cage	Double-sided support prevents media collapse under negative pressure
End Caps	Metal or polyurethane	Bonded to media, also serves as seal carrier
Seal	Nitrile rubber or polyurethane	Prevents bypass between element and housing
Adhesive	Polyurethane	Bonds media to end caps and cage, seals edges

Operating Conditions

Parameter	Value / Note
Operating Temperature	-10 °C to +80 °C
Relative Humidity	≤90% RH (non-condensing)
Burst / Collapse Pressure	Designed to withstand at least 5 kPa differential pressure without deformation
Special Features	Wide power range; pre-filter layer available for high-dust environments to extend main element life

In high-humidity, high-dust or oil-mist environments (textile, foundry, food, cement), media strength decreases with moisture and oil mist can cause surface caking. Both conditions shorten service life and require more frequent inspection.

Service Life and Maintenance

Parameter	Value / Note
Service Life	2000 hours or 3 months, whichever comes first
High-Dust Environment	Reduce hours accordingly (e.g., approx. 1500 hours); time limit also shortened
Shelf Life	Use within 24 months; store in dry, ventilated, dark area, avoid moisture and compression
Replacement Criteria	Intake differential pressure gauge exceeds limit, or media damage, debonding, or seal deformation

The "2000 hours or 3 months" rule applies both limits; whichever comes first. The calendar limit exists because media degrades over time even if operating hours are low, especially for standby or intermittent-duty compressors.

Standards

Standard	Note
ISO 5011	Inlet air filter efficiency and dust holding capacity test method; basis for performance characterization of this type of air filter
GB/T 14295	Chinese national standard for air filters, often referenced in domestic procurement and acceptance
ISO 8573-1	Compressed air quality classes, used to describe compressor system air quality
Note	ISO 2941/2942/2943/3723/3724 series are hydraulic filter standards; ISO 16889 multi-pass method is for liquid filtration; EN 779 and its G4–F9 classes are for ventilation and air conditioning filters. None apply to compressor intake air filter elements.

Standard Maintenance and Installation Steps

1. Confirm compressor status and spare parts. Check compressor nameplate and power rating, confirm that the new element matches the old element's part number (if old element is marked 39708466, it is the same part). Prepare new element, clean cloth and necessary tools.
2. Shut down, depressurize, and disconnect power. Follow shutdown procedure and wait until fully depressurized. Lock out and tag out the main power. This is mandatory.
3. Verify old element before removal. Before opening the intake filter assembly, note the part number stamped on the old element's end cap and its installation position. This element covers 45 models across 37–160 kW; some models have primary and safety filters. This step is critical to avoid errors.
4. Remove and inspect old element. Remove vertically and examine dust distribution and media condition. Replace immediately if media is damaged, punctured, end caps debonded, or seal deformed—even if service interval is not reached. Black oily sludge indicates abnormal oil mist in intake; check upstream environment.
5. Clean housing interior. Wipe inner walls and bottom with lint-free cloth. Do not blow compressed air into the housing; it will drive dust into the intake. Ensure no loose dust and sealing surface is clean and flat.
6. Install new element. Insert in the same orientation and position as old element, ensuring seal faces correct direction and compression. Element should not wobble; seal should be evenly compressed around circumference.
7. Reassemble and confirm sealing. Replace cover or clamp and tighten evenly. Check intake vacuum gauge pressure line for blockage—a blocked line can give a false "clean" reading, a common misdiagnosis.
8. Test run and record. Reset maintenance timer, start compressor unloaded, observe vacuum gauge reading and running sound. Gauge should be stable within allowed range; no abnormal whistling (often indicates seal bypass). Record running hours at replacement as the starting point for next interval.

Frequently Asked Questions

Q1: Is 47701889001 the same as 39708466?

Yes. 39708466 is the previous part number for this element. Ingersoll Rand migrated a batch of M-series air filters from old numbers to new 11-digit numbers; 39708466 corresponds to 47701889001. The old number is now marked as discontinued. Both numbers refer to the same filter element.

Q2: Can 47701889001, 47701890001 and 47701891001 be interchanged?

No. All three belong to the same changeover batch and share the same name, but they serve different power ranges. This element covers 37–160 kW M-series and SM/SL/SH platforms; the other two are for higher power ranges. Always verify by the part number stamped on the old element.

Q3: Which compressor models does this element fit?

Coverage is wider than typical air filters; see the model list in section 6. Typical models 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 compressor nameplate and old element photo for cross-reference.

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

Fit depends on intake assembly interface and resistance at rated flow, not solely on power. The intake assembly interface is common across 45 models from 37 to 160 kW, so the same element is used across three power bands. Larger models may use multiple elements; verify quantity per unit before ordering.

Q5: What are the dimensions?

OD approx. 278–280 mm, ID approx. 156 mm, overall height approx. 127–129 mm, net weight approx. 1.25 kg. Dimensions may vary slightly by batch and media configuration. Measure old element or provide photos and nameplate for verification.

Q6: What is the replacement interval?

Standard interval is 2000 hours or 3 months, whichever comes first. In high-dust environments (cement, quarry, mining, metalworking), reduce to approx. 1500 hours. Always follow intake differential pressure gauge; replace when reading exceeds limit regardless of hours.

Q7: What happens if intake resistance increases?

Energy consumption rises: each 1 kPa increase in intake resistance raises compression ratio by about 1% and energy consumption by about 1%. Air delivery also decreases. Continuing past the replacement threshold costs more in energy than the filter price. This is especially noticeable on continuous-duty compressors.

Q8: Can I use an aftermarket replacement?

Yes, but verify three things: filtration rating, end cap sealing type, and dimensions. If the sealing type does not match the original, bypass can occur, allowing unfiltered air into the airend and accelerating rotor and bearing wear. Provide old element photos and this part number when ordering aftermarket parts.

Q9: What if there is abnormal whistling after installation?

Whistling usually indicates seal bypass—element not fully seated, seal deformed, or seal missing. Stop the compressor immediately and check: element position, seal for flattening or inversion. Also check intake vacuum gauge pressure line for blockage to avoid misdiagnosis.

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

If the intake assembly has two stages (primary + safety), the part numbers and positions differ and are not interchangeable. Replace in order from outside in, and verify each stage against the ordered part number. The safety element acts as a backup if the primary fails and should not be left unchanged just because it looks clean.

Q11: What are the storage requirements?

Store in a dry, ventilated, dark area, protected from moisture, rain and heavy compression. Moisture reduces media strength; compression can deform the seal. Use within 24 months.

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. Use the old element part number as the primary reference, compressor nameplate as secondary, and installation position as tertiary.

Three-Step Verification

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

If still uncertain, provide compressor nameplate photo, old element photo (with stamped part number) and installation position description. We will cross-reference by part number.
