I. Product Overview
54672522 is the intake air filter element (Element, Air Filter) for Ingersoll Rand NG R-Series (Next Generation R-Series) 30–37 kW screw air compressors.
Its location and function on the unit: it is installed inside the external intake filter assembly, upstream of the airend intake. When the unit is running, outside air is drawn in, and dust, sand, and fibers are trapped by the filter media before entering the screw airend. The condition of this filter element directly affects how long the downstream oil-air separator element, oil filter, and lubricating oil will last.
The distinguishing feature of this part number is that it is shared by four models on the same platform: R30I, R30N, R37I, and R37N all use 54672522; the 30 kW and 37 kW power ratings share it, and the fixed-speed (N) and variable-speed (I) configurations also share it. When purchasing, there is no need to distinguish by power rating or speed control method.

III. Product Technical Parameters
1. Filtration Performance Parameters (Core Indicators)
| Parameter | Value / Description |
|---|---|
| Filtration Rating | ≤10 μm |
| Filtration Efficiency | ≥99% (for particles ≥5 μm) |
| Filter Class | Does not follow the ventilation and air-conditioning filter classification system (EN 779); air filter elements are characterized per ISO 5011 by filtration efficiency + intake resistance + dust holding capacity |
| Dust Holding Capacity | Approx. 900 g |
2. Flow and Resistance Parameters
| Parameter | Value / Description |
|---|---|
| Rated processing air volume | Matched to the displacement of the NG R-Series 30–37 kW platform, 1 unit per machine |
| Filtration face velocity | Approx. 0.036 m/s |
| Initial pressure drop (initial resistance) | After installing a new filter element, the machine intake vacuum should stabilize below 0.05 bar (5 kPa) |
| Operating pressure differential range | From the initial resistance of a new filter element to the clogging alarm value |
| Alarm resistance / final resistance | Based on the machine intake vacuum gauge reading and the controller alarm |
| Pressure drop–energy consumption relationship | For every 1 kPa increase in intake resistance, machine energy consumption increases by approx. 1% |
Relationship between pressure drop and energy consumption
Rising intake resistance reduces intake pressure and density; to maintain the set discharge pressure and flow, the machine must do more work, and the Specific Power rises accordingly. Based on a discharge pressure of 0.7 MPa and atmospheric pressure of 101.3 kPa, theoretical calculation by compression ratio gives:
| Intake resistance | Compression ratio | Relative baseline energy consumption increase |
|---|---|---|
| 0 kPa (new filter element) | 7.91 | Baseline |
| 2 kPa | 8.07 | +2.0% |
| 4 kPa | 8.24 | +4.1% |
| 6 kPa | 8.41 | +6.3% |
From brand new to severely clogged (0 → 6 kPa), the machine's energy consumption gradually rises by about 6% over the process. R-Series machines commonly run more than 6000 hours per year; this extra electricity cost far exceeds the price of a filter element, which is also the engineering basis for the factory-set pressure differential alarm.

IV. Standard Maintenance and Installation Steps
Unit: single-person operation, working time approximately 20 minutes.
-
Shut down, depressurize, and apply lockout/tagout Disconnect at the main power supply and apply lockout/tagout. Wait until the controller displays a system pressure of 0 bar. Criterion: the pressure gauge reads zero and there is no residual airflow sound.
-
Open the intake filter housing The filter assembly is externally mounted and located on the enclosure of the R-Series unit. Loosen the end cap latches or bolts. Criterion: latches are not rusted stuck and the end cap is not deformed.
-
Remove the old filter element and observe its condition Remove the old filter element vertically and observe the dust distribution and surface condition. Criterion: uniform grayish-brown dust accumulation is normal; if there is oily residue on the surface, it indicates an oil carryover condition upstream, and the cause needs to be investigated.
-
Clean the interior of the housing Wipe the inner walls and bottom of the housing with a dry, lint-free cloth. Do not blow compressed air into the housing interior (this will blow dust into the intake duct). Criterion: no loose dust on the inner walls; in humid areas, also check the bottom of the housing for condensation.
-
Check the breather filter element The breather filter element (part number 39123111) shares the same 2000-hour interval as the air filter. Take this opportunity to check it: if it is already clogged or heavily dust-laden, it should be replaced at the same time. Criterion: filter media is not damaged and there is no severe dust accumulation.
-
Install the new filter element and confirm the seal Align 54672522 with the housing outlet end and push it in. Push it all the way in and confirm that the radial seal ring is evenly compressed around its circumference, with no trapped material and no skewing. Criterion: the filter element end face is flush with the housing, and the compression marks around the seal ring are uniform.
-
Reassemble, reset the timer, and verify Reinstall the end cap and lock the latches. Reset the air filter maintenance timer on the controller. Start the unit and run at idle for 5 minutes. Criterion: intake vacuum stabilizes below 0.05 bar (5 kPa), indicating a good seal; if the vacuum is high, check whether the seal ring is properly seated.
Installation golden rule: do not start the unit before the filter element is seated or the seal ring is fully compressed. If the radial seal structure is not pushed fully into place, air will bypass directly through the gap between the seal ring and the housing, which is equivalent to having no filter element installed.
V. Frequently Asked Questions
Which models use 54672522?
All four models of 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. In addition, R30, R37, R30IE, and R37IE also use this part number.
Is the air filter for the R30 and R37 the same?
Yes. 54672522 fits both the R30 (30 kW) and R37 (37 kW). The difference between the two lies in motor power and displacement; the filter housing and filter element of the 30–37 kW platform are completely identical.
Can it be used on the R45 or R55?
No. The R45–R75 uses 54672530, and the R90–R110 uses 23429822. Filter housings of different power platforms have different dimensions; cross-platform installation will not fit and cannot seal.
How often should it be replaced?
Under standard operating conditions, 2000 hours or 3 months, whichever comes first. In high-dust environments such as cement, quarrying, and mining, it should be shortened to approximately 1500 hours. If on-site dust levels are chronically excessive, a high-dust pre-filter kit (24737298 / 24737306) can be installed, so that when the pre-filter layer fails, only the pre-filter element needs to be replaced, extending the life of the main filter element.
What else should be replaced together with the air filter?
Parts on the same maintenance interval (2000 hours): oil filter element 54672654, oil separator element 54749247, breather filter element 39123111. All three share the same interval as the air filter, and it is recommended to inspect and replace them at the same time to avoid misaligned maintenance intervals and repeated shutdowns.
Is there a maintenance kit that includes this set of parts?
Yes. 2000-hour kit 24730897 (universal for fixed-speed and variable-speed), 4000-hour fixed-speed kit 24730939, 4000-hour variable-speed kit 24766123.
What 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 filter element be blown clean and reused?
Not recommended. This is a radially sealed pleated paper filter designed for single use. Reverse blowing with compressed air can only remove surface dust; deep fine particles cannot be removed. The reverse blowing pressure can also easily cause breakage of the filter paper fibers or deformation of the pleat spacing, creating channels invisible to the naked eye. Continuing to use a cleaned element results in a state of "looking clean but actually failed," with risks outweighing the benefits.
How do I determine when it should be replaced?
Four signals: ① the unit's intake vacuum gauge reading increases; ② the controller reports maintenance due; ③ after removal, the filter paper surface is completely covered with dust and the original pleat pattern cannot be seen; ④ displacement decreases while energy consumption rises. If any signal appears, it should be replaced.
Is it a genuine OEM part? How to verify authenticity?
The 54672522 introduced on this page is an Ingersoll Rand original equipment part number. Genuine parts carry the Ingersoll Rand anti-counterfeit mark and come with a warranty.

VII. Related parts
In the intake and lubrication system of the R Series 30–37 kW platform, the components maintained on the same cycle as the air filter are as follows (all figure numbers are from the R30I/R30N/R37I/R37N parts manual):
| Component | Figure number | Function | Inspection points |
|---|---|---|---|
| Air Cleaner assembly | 54652565 | Housing assembly that holds and secures the air filter element | Check the clips, sealing surface, and outlet end for deformation |
| Oil Filter | 54672654 | Filters wear debris and sludge from the lubricating oil, protecting bearings and the rotor | Replace together with the air filter; after replacement, check the sealing surface for oil seepage |
| Oil Separator | 54749247 | Separates oil mist from compressed air and returns oil, controlling oil carryover in the discharge | During replacement, also check whether the oil return line is blocked |
| Breather Filter | 39123111 | Balances pressure in the oil separator tank and prevents external dust from entering the oil circuit | Inspect together with the air filter; replace at the same time if blocked |
| Lubricant (Ultra Coolant) | 38459582 | Standard coolant for R Series screw compressors, providing both lubrication and sealing | Test the oil according to unit requirements; avoid mixing with other brands |
| 2000-hour maintenance kit | 24730897 | Maintenance kit common to fixed-speed and variable-frequency units | Supplies all wear parts for the same cycle at once, reducing the number of shutdowns |
| 4000-hour maintenance kit | 24730939 (fixed speed) / 24766123 (variable frequency) | Major maintenance kit | Schedule according to unit operating hours |
| High-dust pre-filter kit | 24737298 / 24737306 | Additional pre-filter layer for sites with excessive dust | When the pre-filter layer fails, replace only the pre-filter part to extend the life of the main filter element |
Replacement recommendation: the air filter, oil filter, and oil separator share the same 2000-hour cycle. It is recommended to replace them at the same time to avoid misaligned maintenance cycles caused by replacing individual parts. At sites with heavy dust, install the high-dust pre-filter kit first; the cost of the pre-filter part is far lower than that of the main filter element, and replacement is faster.
