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 is mounted 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 how long downstream components — the oil separator, oil filter, and lubricant — will last.

This part number is shared across four models on the same platform: R30I, R30N, R37I, and R37N. Both 30 kW and 37 kW units use it, and both fixed-speed (N) and variable-speed (I) configurations use the same element. No differentiation by power rating or speed control is required at the point of purchase.

Flow & Restriction

Parameter	Value / Note
Rated Air Flow	Matched to NG R-Series 30–37 kW platform output; one element per compressor
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	From initial restriction of a new element to the clogging alarm set point
Alarm / Final Restriction	Per compressor intake vacuum gauge reading and controller alarm
Restriction vs. Energy	Every 1 kPa increase in intake restriction raises compressor energy consumption by approximately 1%

Restriction and energy consumption

Rising intake restriction lowers intake pressure and density. To maintain the set discharge pressure and flow, the compressor must do more work, and specific power increases. Based on a 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure, the theoretical compression ratio effect is:

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 a filter element goes from new to heavily clogged (0 → 6 kPa), compressor energy consumption rises by roughly 6%. R-Series units commonly run 6,000+ hours per year. The added electricity cost far exceeds the price of a filter element — which is the engineering basis for the factory-set differential pressure alarm.

Standard Installation Steps

One person, approximately 20 minutes.

1. Shut down, depressurize, lock out/tag out
   Disconnect and lock out the main power. Wait until the controller shows 0 bar system pressure. Criterion: pressure gauge reads 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 latches or bolts. Criterion: latches not seized, cover not deformed.

3. Remove the old element and inspect it
   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 oil carryover upstream and requires investigation.

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 loaded, replace it at the same time. Criterion: media intact, no severe dust loading.

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

7. Reassemble, reset the timer, and verify
   Refit the end cover and tighten 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 correctly.

Installation rule: Do not start the compressor before the element is fully seated and the seal is compressed. With a radial seal, if the element is not pushed fully home, air bypasses directly through the gap 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.

Do the R30 and R37 use the same air filter?
Yes. 54672522 fits both R30 (30 kW) and R37 (37 kW). The difference between the two is motor power and air output; the filter housing and element on the 30–37 kW platform are identical.

Can it be used on an R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Filter housings differ by power platform; a cross-platform element will not fit or seal.

How often should it be replaced?
Standard conditions: 2,000 hours or 3 months, whichever comes first. In high-dust environments such as cement, quarry, or mining, shorten to approximately 1,500 hours. Where site dust is consistently high, a high-dust pre-filter kit (24737298 / 24737306) can be installed so that only the pre-filter layer is replaced when it loads up, 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 air filter's interval; replacing them together avoids staggered maintenance cycles and repeated downtime.

Is there a service kit containing these parts?
Yes. The 2,000-hour kit is 24730897 (for both fixed-speed and variable-speed). The 4,000-hour fixed-speed kit is 24730939; the 4,000-hour variable-speed kit is 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 needs replacing?
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 pleat pattern is not visible; (4) air output drops while energy consumption rises. Any one signal calls for replacement.

Is this a genuine part? How do I verify?
54672522 is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand anti-counterfeit identification and a warranty. When purchasing, rely on the part number itself — the part number is the only identity that cannot be confused. Do not order based solely on "fits R30/R37" or visual similarity.

Breather Filter	39123111	Balances pressure in the separator tank; prevents external dust from entering the oil circuit	Inspect with the air filter; replace if clogged
Lubricant (Ultra Coolant)	38459582	Standard coolant for R-Series screw compressors; lubricates and seals	Test oil per compressor requirements; avoid mixing with other brands
2,000-Hour Service Kit	24730897	Service kit for fixed-speed 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 according to 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 grouping: The air filter, oil filter, and oil separator share the 2,000-hour interval. Replace them together to avoid staggered maintenance cycles. At dusty sites, install the high-dust pre-filter kit first — pre-filter elements cost far less than the main element and are faster to change.
