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 installed inside the external air cleaner assembly, upstream of the airend intake. As the first filtration barrier in the compressed air system, its condition directly affects the service life of the downstream oil separator, oil filter, and lubricant.
The key advantage of this part number is platform-wide commonality: R30I, R30N, R37I, and R37N all use 54672522. Both 30 kW and 37 kW models, and both fixed-speed (N) and variable-speed (I) configurations, share the same element. No differentiation by power rating or speed control is required at the point of purchase.

Filtration Performance
| Parameter | Value / Notes |
|---|---|
| Filtration Rating | ≤10 μm |
| Filtration Efficiency | ≥99% for particles ≥5 μm |

| Dust Holding Capacity | Approx. 900 g |
Flow and Restriction
| Parameter | Value / Notes |
|---|---|
| Rated Air Flow | Matched to NG R-Series 30–37 kW platform displacement; one element per compressor |
| Filtration 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) |
| Operating Differential Range | From initial restriction of a new element to the clogging alarm threshold |
| Alarm / Final Restriction | Per compressor intake vacuum gauge reading and controller alarm |
| Restriction vs. Energy | Each 1 kPa increase in intake restriction raises compressor energy consumption by approximately 1% |
Restriction and energy relationship
Rising intake restriction reduces intake pressure and air density. To maintain set discharge pressure and flow, the compressor must do more work, and specific power increases. Theoretical compression ratio calculations at 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% |
Engineering implication: As the element progresses from new to heavily clogged (0 → 6 kPa), compressor energy consumption rises by approximately 6%. R-Series compressors commonly run over 6000 hours per year, and the additional electricity cost far exceeds the price of one element. This is the engineering basis for the factory-set differential pressure alarm.

Installation and Maintenance Steps
One person, approximately 20 minutes.
Shut down, depressurize, lock out / tag out. Disconnect and lock out the main power supply. Wait until the controller shows system pressure at 0 bar. Criterion: gauge reads zero, no residual air flow noise.
Open the air cleaner housing. The air cleaner assembly is externally mounted on the R-Series enclosure. Release the end cover latches or bolts. Criterion: latches free of seizure, cover not deformed.
Remove the old element and inspect its condition. Pull the old element straight out and observe dust distribution and surface condition. Criterion: uniform gray-brown dust loading is normal; oily residue on the surface indicates upstream oil carryover and requires investigation.
Clean the housing interior. Wipe the inner walls and bottom with a dry, lint-free cloth. Do not blow compressed air into the housing — this drives dust into the intake passage. Criterion: no loose dust on inner walls; in humid areas, also check for condensate at the housing bottom.
Check the breather filter. The breather filter (part number 39123111) shares the same 2000-hour interval. Inspect it now: if clogged or heavily loaded, replace it at the same time. Criterion: media intact, no severe dust loading.
Install the new element and confirm the seal. Align 54672522 with the housing outlet and push in fully. Confirm the radial seal ring is evenly compressed around the circumference with no trapped material or skew. Criterion: element face flush with housing, uniform seal impression around the ring.
Reassemble, reset the timer, and verify. Refit the end cover and secure the latches. Reset the air filter service timer on the controller. Start the compressor and run at idle for 5 minutes. Criterion: intake vacuum stabilizes below 0.05 bar (5 kPa), indicating a proper seal; if vacuum is high, check that the seal ring is seated correctly.
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 the seal ring and housing — equivalent to running without a filter.
Frequently Asked Questions
Which models use 54672522?
All four models in 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 air filter the same for R30 and R37?
Yes. 54672522 fits both R30 (30 kW) and R37 (37 kW). The difference between the two is motor power and displacement; the 30–37 kW platform shares 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; cross-platform installation will not fit or seal.
How often should it be replaced?
Standard conditions: 2000 hours or 3 months, whichever comes first. In high-dust environments such as cement, quarrying, or mining, shorten to approximately 1500 hours. If site dust is consistently high, install the high-dust pre-filter kit (24737298 / 24737306) so that only the pre-filter is replaced when it loads, extending main element life.
What else should be replaced with the air filter?
Parts sharing the same 2000-hour service interval include: oil filter 54672654, oil separator 54749247, and breather filter 39123111. These share the same interval as the air filter; inspect and replace together to avoid staggered maintenance and repeated downtime.
Is there a service kit containing these parts?
Yes. 2000-hour kit 24730897 (fixed and variable speed), 4000-hour fixed-speed kit 24730939, and 4000-hour variable-speed kit 24766123.
Which lubricant should be used?
Ingersoll Rand Ultra Coolant, part number 38459582, suitable 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 only removes surface dust; deep fine particles cannot be removed, and back-blow pressure can rupture media fibers or distort pleat spacing, creating invisible channels. Reusing a cleaned element is a "looks clean, actually failed" condition with more risk than benefit.
How do I know it is time to replace?
Four signals: ① intake vacuum gauge reading rises; ② controller indicates service due; ③ after removal, the filter paper surface is completely covered with dust and the original pleats are not visible; ④ discharge flow drops while energy consumption rises. Replace on any one signal.
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 identification and warranty. Always order by the part number itself — the part number is the only unambiguous identifier. Do not order based solely on "fits R30/R37" or visual similarity.

Reading the table
- All eight models above use this product and belong to the NG R-Series 30–37 kW platform. Fixed or variable speed, and whether a dryer is included, do not affect air filter selection.
- Cross-power-platform interchange is not possible. 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 photo of the nameplate and the full model number. We will confirm by reverse lookup from the part number before you order.
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 Points |
|---|---|---|---|
| Air Cleaner Assembly | 54652565 | Housing that holds and secures the air filter element | Check latches, sealing surfaces, and outlet end for deformation |
| Oil Filter | 54672654 | Removes wear debris and sludge from lubricant, protecting bearings and rotors | Replace with air filter; check sealing surfaces for leaks after replacement |
| Oil Separator | 54749247 | Separates oil mist from compressed air and returns oil, controlling oil carryover | Inspect oil return line for blockage during replacement |
| Breather Filter | 39123111 | Balances pressure in the separator tank, preventing external dust from entering the oil circuit | Inspect with air filter; replace if clogged |
| Lubricant (Ultra Coolant) | 38459582 | Standard coolant for R-Series screw compressors, providing lubrication and sealing | Test oil per compressor requirements; avoid mixing with other brands |
| 2000-Hour Service Kit | 24730897 | Service kit for fixed and variable speed | Supplies all same-interval wear parts at once, reducing downtime |
| 4000-Hour Service Kit | 24730939 (fixed speed) / 24766123 (variable speed) | Major service kit | Schedule per compressor running hours |
| High-Dust Pre-Filter Kit | 24737298 / 24737306 | Additional pre-filter layer for high-dust sites | Replace only the pre-filter when loaded, extending main element life |
Recommended replacement practice: The air filter, oil filter, and oil separator share the 2000-hour interval. Replace them together to avoid staggered maintenance. For dusty sites, prioritize the high-dust pre-filter kit — the pre-filter costs far less than the main element and is faster to change.
