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 the compressor draws in ambient air, dust, grit, and fibers are captured before they reach the airend. The condition of this element directly affects the service life of the downstream oil separator, oil filter, and lubricant.
A key advantage of this part number is that it is shared across four models on the same platform: R30I, R30N, R37I, and R37N. Both 30 kW and 37 kW ratings use it, and both fixed-speed (N) and variable-speed (I) configurations use it. No differentiation by power or speed control is required at the time of purchase.

Flow and Pressure Drop
| Parameter | Value / Note |
|---|---|
| Rated Air Flow | Matched to NG R-Series 30–37 kW displacement; one element per compressor |
| Filtration Face Velocity | Approx. 0.036 m/s |
| Initial Pressure Drop | With a new element installed, intake vacuum should stabilize below 0.05 bar (5 kPa) |
| Operating Differential Pressure | From new-element initial restriction to clogging alarm setpoint |
| Alarm / Final Restriction | Per compressor intake vacuum gauge and controller alarm |
| Pressure Drop vs. Energy | Each 1 kPa rise in intake restriction increases compressor energy consumption by approx. 1% |
Pressure Drop and Energy Consumption
Rising intake restriction lowers intake pressure and density; the compressor must work harder to maintain set discharge pressure and flow, increasing specific power. Based on a theoretical compression ratio calculation at 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure:
| Intake Restriction | Compression Ratio | Relative Energy Increase vs. Baseline |
|---|---|---|
| 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% |
As an element goes from new to heavily clogged (0 → 6 kPa), compressor energy consumption rises by approximately 6%. R-Series compressors often run over 6000 hours per year; the extra electricity cost far exceeds the price of an element. This is the engineering basis for the OEM pressure-drop alarm setting.

Standard Maintenance and Installation Steps
One person, approx. 20 minutes.
Shut down, depressurize, lock out/tag out. Disconnect and lock out main power. 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 is externally mounted 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 vertically and observe dust distribution and surface condition. Criterion: uniform gray-brown dust is normal; oily residue indicates oil carryover upstream 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 (it will drive dust into the intake). Criterion: no loose dust on inner walls; in humid regions, also check for condensation at the housing bottom.
Check the breather filter. The breather filter (part number 39123111) shares the 2000-hour interval with the air filter. 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 end and push in fully. Confirm the radial seal ring is evenly compressed around its circumference, with no pinching or skewing. Criterion: element face flush with housing, uniform seal compression marks.
Reassemble, reset the timer, and verify. Refit the 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 good seal; if vacuum is high, check that the seal ring is seated.
Installation rule: Do not start the compressor before the element is fully seated and the seal ring is compressed. If a radial-seal element is not pushed fully home, air bypasses directly through the gap between seal and housing — equivalent to running with no filter 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 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 filter housing and element on the 30–37 kW platform are identical.
Can it be used on R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Filter housing dimensions differ across power platforms; cross-platform installation will not fit or seal.
How often should it be replaced?
Under standard conditions, 2000 hours or 3 months, whichever comes first. In high-dust environments such as cement, quarry, or mining, shorten to approx. 1500 hours. If site dust is persistently high, consider a high-dust pre-filter kit (24737298 / 24737306) so that only the pre-filter is replaced when it loads up, extending 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 same interval as the air filter; replacing them together avoids staggered maintenance and repeated downtime.
Is there a service kit containing these parts?
Yes. 2000-hour kit 24730897 (for 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. Reverse blowing with compressed air only removes surface dust; deep fine particles remain. Blow pressure can also rupture media fibers or deform pleat spacing, creating invisible channels. Reusing a cleaned element is a "looks clean, actually failed" condition — the risk outweighs the 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 media surface is fully 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 on this page is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand anti-counterfeit markings and come with 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.

How to Read the Table
- All eight models above use this product; they belong to the NG R-Series 30–37 kW platform. Fixed or variable speed, with or without dryer, does not affect air filter selection.
- Cross-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 cross-check by part number before you order.
Related Components
In the intake and lubrication system of the R-Series 30–37 kW platform, the following components are maintained on the same 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 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 surface for leaks after replacement |
| Oil Separator | 54749247 | Separates oil mist from compressed air and returns oil; controls oil carryover | Check oil return line for blockage during replacement |
| Breather Filter | 39123111 | Balances pressure in the separator tank and prevents 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; lubricates and seals | Test oil per compressor requirements; do not mix with other brands |
| 2000-Hour Service Kit | 24730897 | Service kit for fixed and variable speed | Supplies all same-interval wear parts in one order, reducing downtime |
| 4000-Hour Service Kit | 24730939 (fixed) / 24766123 (variable) | Major service kit | Schedule according to 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: air filter, oil filter, and oil separator share the 2000-hour interval. Replace them together to avoid staggered maintenance. At dusty sites, prioritize the high-dust pre-filter kit — the pre-filter costs far less than the main element and is quicker to change.
