Ingersoll Rand 54672522 Air Filter | R30/R37 NG R-Series OEM Element

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.

It sits inside the external air cleaner assembly, upstream of the airend intake. As the machine draws in ambient air, dust, grit and fibres are captured by the media before they reach the screw airend. This element is the first filtration barrier in the compressed air system, and its condition directly affects how long the downstream oil separator, oil filter and lubricant will last.

The key feature of this part number is that it is shared across four models on the same platform: R30I, R30N, R37I and R37N all use 54672522 — covering both 30 kW and 37 kW ratings, and both fixed-speed (N) and variable-speed (I) configurations. No distinction by power or speed control is required at the point of purchase.

Technical Parameters

Filtration Performance

Parameter	Value / Notes
Filtration rating	≤10 μm
Filtration efficiency	≥99% for particles ≥5 μm
Filter class	HVAC filter classification (EN 779) does not apply; air intake elements are characterised under ISO 5011 by efficiency, intake restriction and dust holding capacity
Dust holding capacity	Approx. 900 g

Flow and Pressure Drop

Parameter	Value / Notes
Rated air flow	Matched to NG R-Series 30–37 kW displacement; one element per machine
Face velocity	Approx. 0.036 m/s
Initial pressure drop	With a new element fitted, intake vacuum should stabilise below 0.05 bar (5 kPa)
Operating differential range	From new-element initial restriction to the clogging alarm value
Alarm / final restriction	Per the machine intake vacuum gauge reading and controller alarm
Pressure drop vs. energy	Each 1 kPa rise in intake restriction increases machine energy consumption by roughly 1%

Pressure drop and energy consumption

Rising intake restriction lowers intake pressure and density; to hold the set discharge pressure and flow, the machine must do more work and specific power rises. Calculated on compression ratio at 0.7 MPa discharge and 101.3 kPa atmospheric:

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 an element goes from new to heavily clogged (0 → 6 kPa), machine energy consumption climbs by roughly 6%. R-Series machines commonly run 6,000+ hours a year, and the extra electricity cost far exceeds the price of one element — the engineering basis for the factory-set differential pressure alarm.

Construction and Installation Data

Parameter	Value / Notes

Standard applicability note	The ISO 29xx / 37xx series are in fact general test methods for hydraulic fluid power filter elements. Where a supplier can only offer hydraulic filter standards, request ISO 5011 data or the OEM specification sheet.

Standard Installation and Maintenance Steps

One person, approximately 20 minutes.

1. Shut down, depressurise, lock out/tag out. Isolate and lock out the main power supply. Wait until the controller shows 0 bar system pressure. Check: gauge at zero, no residual air flow noise.

2. Open the air cleaner housing. The air cleaner is externally mounted on the R-Series enclosure. Release the end-cover clips or bolts. Check: clips not seized, cover not distorted.

3. Remove the old element and inspect it. Lift the old element out vertically and note the dust pattern. Check: even grey-brown dust loading is normal; oily residue on the surface indicates oil carry-over upstream and requires investigation.

4. Clean the housing interior. Wipe the inner wall and base with a dry, lint-free cloth. Do not blow compressed air into the housing — it drives dust into the intake tract. Check: no loose dust on the inner wall; in humid locations also check the housing base for condensate.

5. Inspect the breather filter. The breather filter (part 39123111) shares the 2,000-hour interval. Check it now: replace it as well if clogged or heavily loaded. Check: media intact, no heavy dust loading.

6. Fit the new element and confirm the seal. Align 54672522 with the housing outlet and push it fully home, confirming the radial seal ring is evenly compressed with no trapped material and no skew. Check: element face flush with the housing, even seal compression all round.

7. Reassemble, reset the timer and verify. Refit the cover and tighten the clips. Reset the air filter service timer on the controller. Start the machine and run at idle for 5 minutes. Check: intake vacuum stabilises below 0.05 bar (5 kPa), confirming a good seal; if vacuum is high, check that the seal ring is seated.

Installation rule: never start the machine before the element is seated and the seal ring compressed. With a radial-seal design, an element that is not pushed fully home lets air bypass straight between the 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 and 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 air cleaner housing and element on the 30–37 kW platform are identical.

Will it fit an R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Air cleaner housings differ in size between power platforms, so a cross-platform element will not fit or seal.

How often should it be replaced?
Every 2,000 hours or 3 months under standard conditions, whichever comes first. In cement, quarry or mining environments with heavy dust, shorten to around 1,500 hours. Where site dust is persistently high, a high-dust pre-filter kit (24737298 / 24737306) lets you replace only the pre-filter layer and extend main element life.

What else should be changed at the same time?
Parts on the same 2,000-hour interval: oil filter 54672654, oil separator 54749247 and breather filter 39123111. All share the air filter's interval — inspect and replace together to avoid staggered maintenance and repeated downtime.

Is there a service kit covering these parts?
Yes. The 2,000-hour kit is 24730897 (common to fixed and variable speed); the 4,000-hour fixed-speed kit is 24730939 and the 4,000-hour variable-speed kit is 24766123.

Which lubricant should be used?
Ingersoll Rand Ultra Coolant, part 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 pleated paper element with a radial seal, designed as a single-use item. Reverse blowing with compressed air removes only surface dust; fine particles embedded deeper cannot be cleared, and the pressure can rupture fibres or distort pleat spacing, creating invisible paths. A washed element looks clean but has lost its efficiency, so the risk outweighs any benefit.

How do I know it is time to change?
Four signals: (1) rising intake vacuum gauge reading; (2) controller service-due alarm; (3) after removal, the media surface is fully covered in dust with no visible pleat pattern; (4) falling discharge flow with rising energy consumption. Any one signal means replace.

Is this a genuine part, and how is counterfeiting prevented?
The 54672522 described here is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand anti-counterfeit marking and a warranty. When purchasing, order by the part number itself — the part number is the only unambiguous identifier; do not order on the basis of "fits R30/R37" or visual similarity alone.

How to read this table

• All eight models above use the product on this page and belong to the NG R-Series 30–37 kW platform. Fixed or variable speed, and whether a dryer is fitted, do not affect air filter selection.
• Elements are not interchangeable across power platforms. Air filter part numbers for other power bands in the series:

Power platform	Air filter part number
R45–R75 (45–75 kW)	54672530
R90–R110 (90–110 kW)	23429822

• If the model on your machine nameplate is not listed above, send a photo of the nameplate and the full model code; we will confirm by reverse lookup against the part number before you order.

Related Components

Within the intake and lubrication system of the R-Series 30–37 kW platform, the following parts are serviced on the same 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 carries and locates the air filter element	Check clips, sealing faces and outlet end for distortion
Oil filter	54672654	Removes wear debris and sludge from lubricant, protecting bearings and rotors	Replace with the air filter; check sealing face for leaks afterwards
Oil separator	54749247	Separates oil mist from compressed air and returns oil, controlling oil carry-over	Check the return line for blockage at the same time
Breather filter	39123111	Balances pressure in the separator tank and keeps external dust out of the oil circuit	Inspect with the air filter; replace if clogged
Lubricant (Ultra Coolant)	38459582	Standard coolant for R-Series screw compressors, providing lubrication and sealing	Test oil per machine requirements; avoid mixing with other brands
2,000-hour service kit	24730897	Service pack common to fixed and variable speed	Supplies all same-interval wear parts in one order, reducing downtime
4,000-hour service kit	24730939 (fixed speed) / 24766123 (variable speed)	Major service kit	Schedule by machine running hours
High-dust pre-filter kit	24737298 / 24737306	Additional pre-filter layer for sites with excessive dust	Replace only the pre-filter layer when spent, extending main element life

Recommended group replacement: the air filter, oil filter and oil separator share the 2,000-hour interval and should be replaced together to avoid staggered service schedules. On dusty sites, fit the high-dust pre-filter kit first — the pre-filter costs far less than the main element and is quicker to change.
