Product Overview
54672522 is the intake air filter element for Ingersoll Rand NG R-Series (Next Generation R-Series) 30–37 kW screw air compressors. It is mounted inside the external air cleaner assembly, upstream of the airend intake. As ambient air is drawn in, dust, grit and fibers are captured before they reach the airend — protecting the oil separator, oil filter and lubricant service life downstream.
A key sourcing advantage: one part number covers four models on the same platform. R30I, R30N, R37I and R37N all use 54672522, regardless of 30 kW or 37 kW rating, and regardless of fixed-speed (N) or variable-speed (I) configuration. No need to differentiate by power or drive type at ordering.

Technical Parameters
Filtration Performance
| Parameter | Value / Notes |
|---|---|
| Filtration Rating | ≤10 μm |

| Dust Holding Capacity | Approx. 900 g |
Flow and Pressure Drop
| Parameter | Value / Notes |
|---|---|
| Rated Air Flow | Matched to NG R-Series 30–37 kW platform output; one element per compressor |
| Face Velocity | Approx. 0.036 m/s |
| Initial Pressure Drop | After installing a new element, intake vacuum should stabilize below 0.05 bar (5 kPa) |
| Alarm / Final Restriction | Per compressor intake vacuum gauge reading and controller alarm |
| Pressure Drop vs. Energy | Every 1 kPa increase in intake restriction raises compressor energy consumption by approx. 1% |
Pressure Drop and Energy Consumption
Rising intake restriction lowers intake pressure and density. To maintain set discharge pressure and flow, the compressor must do more work, and specific power rises. Based on 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure:
| Intake Restriction | Compression Ratio | Relative Energy Increase |
|---|---|---|
| 0 kPa (new element) | 7.91 | Baseline |
| 2 kPa | 8.07 | +2.0% |
| 4 kPa | 8.24 | +4.1% |
| 6 kPa | 8.41 | +6.3% |
From new to heavily loaded (0 → 6 kPa), compressor energy consumption rises by about 6%. R-Series units commonly run 6000+ hours per year — the extra electricity cost far exceeds the price of an element, which is the engineering basis for the factory-set differential pressure alarm.

Standard Installation and Maintenance Procedure
One person, approx. 20 minutes.
- Shut down, depressurize, lock out/tag out. Disconnect and lock out the main power. Wait until the controller shows system pressure at 0 bar. Criterion: gauge at zero, no residual air flow noise.
- Open the air cleaner housing. The filter assembly is external, on the R-Series enclosure. Release the end-cover latches or bolts. Criterion: latches not seized, cover not deformed.
- Remove the old element and inspect its condition. Pull the element straight out and observe dust distribution and surface condition. Criterion: uniform gray-brown dust is normal; oily residue indicates upstream oil carryover and needs investigation.
- Clean the housing interior. Wipe the inner walls and base with a dry, lint-free cloth. Do not blow compressed air into the housing (it drives dust into the intake). Criterion: no loose dust on inner walls; in humid areas also check for condensation at the housing base.
- Check the breather filter. The breather filter (part number 39123111) shares the 2000-hour interval with the air filter. Inspect now: replace if clogged or heavily loaded. Criterion: media intact, no heavy dust loading.
- Install the new element and confirm the seal. Align 54672522 with the housing outlet and push fully home; confirm the radial seal ring is evenly compressed, with no trapped material and no skew. Criterion: element face flush with housing, uniform seal ring compression marks.
- Reassemble, reset the timer and verify. Refit the cover and tighten latches. Reset the air filter service timer on the controller. Start the compressor and run at idle for 5 minutes. Criterion: intake vacuum stable below 0.05 bar (5 kPa), indicating a good seal; if vacuum is high, check that the seal ring is seated.
Installation rule: Do not start the compressor until the element is fully seated and the seal ring is compressed. With a radial seal, if the element is not pushed fully home, air bypasses directly through the gap between seal ring and housing — equivalent to running with no element at all.
Frequently Asked Questions
Which models use 54672522?
All four models on the NG R-Series 30–37 kW platform: R30I, R30N, R37I, R37N. Fixed-speed (N) and variable-speed (I) configurations share the same air filter. R30, R37, R30IE and R37IE also use this part number.
Is the R30 and R37 air filter the same?
Yes. 54672522 fits both R30 (30 kW) and R37 (37 kW). The difference is motor power and displacement; the 30–37 kW platform uses the same filter housing and element.
Can it be used on R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Filter housings differ across power platforms — a cross-platform element will not fit or seal.
How often should it be replaced?
2000 hours or 3 months under standard conditions, whichever comes first. In high-dust environments such as cement, quarrying or mining, shorten to approx. 1500 hours. Where dust levels are persistently high, add the high-dust pre-filter kit (24737298 / 24737306) — when the pre-filter layer fails, replace only the pre-filter to extend main element life.
What else should be replaced with the air filter?
Parts on the same 2000-hour service interval: oil filter 54672654, oil separator 54749247, breather filter 39123111. These share the interval with the air filter; replace together to avoid staggered maintenance and repeated downtime.
Is there a service kit covering these parts?
Yes. 2000-hour kit 24730897 (for both fixed-speed and variable-speed), 4000-hour fixed-speed kit 24730939, and 4000-hour variable-speed kit 24766123.
What lubricant should be used?
Ingersoll Rand Ultra Coolant, part number 38459582, for all R-Series screw compressors. Available in 5 L, 20 L and 55-gallon sizes.
Can a dirty element be blown clean and reused?
Not recommended. This is a radial-seal pleated paper element designed for single use. Back-blowing with compressed air removes only surface dust; deep fine particles remain, and air pressure can fracture media fibers or deform pleat spacing, creating invisible channels. Reusing a cleaned element is a "looks clean, actually failed" condition — risk outweighs benefit.
How do I know it needs replacing?
Four signals: (1) rising intake vacuum gauge reading; (2) controller service-due alarm; (3) media surface fully covered with dust, original pleats no longer visible; (4) reduced discharge flow with increased energy consumption. Any one signal warrants replacement.
Is this a genuine part? How to verify?
The 54672522 described here is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand anti-counterfeit marking and warranty. Always order by the part number itself — it is the only unambiguous identifier. Do not order based solely on "fits R30/R37" or visual similarity.

Reading Notes
- All eight models above use this product and belong to the NG R-Series 30–37 kW platform. Fixed or variable speed, with or without dryer, does not affect air filter selection.
- Not interchangeable across power platforms. Air filter part numbers for other power ranges in the same series:
| Power Platform | Air Filter Part Number |
|---|---|
| R45–R75 (45–75 kW) | 54672530 |
| R90–R110 (90–110 kW) | 23429822 |
- If your compressor nameplate model is not listed above, provide a nameplate photo and full model number; we will cross-check by part number before ordering.
Related Parts
In the intake and lubrication system of the R-Series 30–37 kW platform, the following parts share the same service interval as the air filter (part numbers from the R30I/R30N/R37I/R37N parts manual):
| Component | Part Number | Function | Inspection Point |
|---|---|---|---|
| Air Cleaner Assembly | 54652565 | Housing assembly that holds and secures the air filter element | Check latches, sealing faces and outlet end for deformation |
