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

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

A key feature of this part number is that four models on the same platform share it: R30I, R30N, R37I and R37N all use 54672522. Both 30 kW and 37 kW, and both fixed-speed (N) and variable-speed (I) configurations, use the same element. No differentiation by power or speed control is needed at the time of purchase.

Fitment confirmation: This part number covers the NG R-Series 30–37 kW platform. Do not apply it to other power ranges — R45–R75 uses 54672530, and R90–R110 uses 23429822. Filter housings differ between power platforms and are not interchangeable. Confirm by checking the machine nameplate or reading the part number on the old element.

Filtration Performance

Parameter	Value / Note
Filtration Rating	≤10 μm
Filtration Efficiency	≥99% for particles ≥5 μm
Filter Class	HVAC filter classification (EN 779) does not apply; air filters are characterized per ISO 5011 by efficiency, restriction and dust holding capacity
Dust Holding Capacity	Approx. 900 g

Flow and Restriction

Parameter	Value / Note
Rated Air Flow	Matched to NG R-Series 30–37 kW platform output; 1 element per machine
Face Velocity	Approx. 0.036 m/s
Initial Pressure Drop	After installing a new element, intake vacuum should remain below 0.05 bar (5 kPa)
Operating Differential Range	From new-element initial restriction to clogging alarm value
Alarm / Final Restriction	Per machine intake vacuum gauge reading and controller alarm
Restriction vs. Energy	Each 1 kPa increase in intake restriction raises machine energy consumption by approximately 1%

Restriction and energy relationship

Rising intake restriction lowers intake pressure and density. To maintain set discharge pressure and flow, the machine must do more work, and specific power rises. 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
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 rises by roughly 6% over that period. R-Series machines commonly run more than 6,000 hours per year, and the extra electricity cost far exceeds the price of one filter element — this is the engineering basis for the factory-set differential pressure alarm.

Standard Applicability Note	The ISO 29xx / 37xx series are general test methods for hydraulic fluid power filter elements. If a supplier can only provide hydraulic filter standards, request ISO 5011 data or the OEM specification sheet.

Standard Maintenance and Installation Steps

One person, approximately 20 minutes.

1. 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.

2. Open the air cleaner housing
   The air cleaner is external, mounted on the R-Series enclosure. Release the end cap latches or bolts. Criterion: latches not seized, end cap not deformed.

3. 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 is normal; oily residue on the surface indicates an upstream oil carryover issue that should be investigated.

4. 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.

5. Check the breather filter
   The breather filter (part number 39123111) shares the same 2,000-hour interval as the air filter. Inspect it now: if clogged or heavily contaminated, replace it at the same time. Criterion: media intact, no heavy dust accumulation.

6. Install the new element and confirm the seal
   Align 54672522 with the housing outlet end and push it in all the way. Confirm the radial seal ring is evenly compressed around its circumference, with no trapped material or skewing. Criterion: element face flush with housing, uniform seal impression all around.

7. Reassemble, reset the timer and verify
   Refit the end cap and tighten the latches. Reset the air filter service timer on the controller. Start the machine 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 whether the seal ring is seated.

Installation rule: Do not start the machine 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 the seal and the housing — equivalent to running without a filter.

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 them is motor power and air output; 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 housings differ between power platforms; a cross-platform element will not fit or seal.

How often should it be replaced?
2,000 hours or 3 months under standard conditions, whichever comes first. In high-dust environments such as cement, quarrying or mining, shorten to approximately 1,500 hours. If site dust is consistently high, a high-dust pre-filter kit (24737298 / 24737306) can be added so that only the pre-filter is replaced when it fails, extending main element life.

What else should be replaced at the same time?
Parts on the same 2,000-hour service interval: oil filter 54672654, oil separator 54749247 and breather filter 39123111. These share the same interval as the air filter, so check and replace them together to avoid staggered maintenance and repeated downtime.

Is there a service kit containing these parts?
Yes. 2,000-hour kit 24730897 (for both fixed and variable speed), 4,000-hour fixed-speed kit 24730939, and 4,000-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 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 the blow pressure can break media fibers or distort pleat spacing, creating invisible paths. Reusing a cleaned element is a "looks clean, actually failed" condition — the risk outweighs the benefit.

How do I know it needs replacing?
Four signals: ① intake vacuum gauge reading rises; ② controller indicates service due; ③ after removal, the media surface is completely covered with dust and the original pleats are not visible; ④ air output drops while energy consumption rises. Replace on any one signal.

Is it 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 — the part number is the only unambiguous identifier. Do not order based only on "fits R30/R37" or visual similarity.

How to read this 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 fitted do not affect air filter selection.
• Elements are 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 machine 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 Parts

In the intake and lubrication system of the R-Series 30–37 kW platform, the following parts 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 assembly 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 oil seepage after replacement
Oil Separator	54749247	Separates oil mist from compressed air and returns oil, controlling oil carryover	Check oil return line for blockage when replacing
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, providing lubrication and sealing	Test oil per machine requirements; avoid mixing with other brands
2,000-Hour Service Kit	24730897	Service kit for fixed and variable speed	Supply all same-interval wear parts in one order to reduce downtime
4,000-Hour Service Kit	24730939 (fixed) / 24766123 (variable)	Major service kit	Schedule by machine running hours
High-Dust Pre-Filter Kit	24737298 / 24737306	Added pre-filter layer for sites with excessive dust	Replace only the pre-filter when it fails, extending main element life

Recommended group replacement: The air filter, oil filter and oil separator share the 2,000-hour interval. Replace them together to avoid staggered maintenance. For dusty sites, add the high-dust pre-filter kit first — the pre-filter costs far less than the main element and is faster to change.
