Ingersoll Rand 54672522 Air Filter for R30/R37 R-Series Compressors

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 intake. As ambient air is drawn in, dust, grit, and fibers are captured by the media before reaching 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.

The key advantage of this part number is four models on one platform share it: R30I, R30N, R37I, and R37N all use 54672522. Both 30 kW and 37 kW ratings, and both fixed-speed (N) and variable-speed (I) configurations, take the same element. No need to differentiate by power or speed control when ordering.

Technical Specifications

Filtration Performance

Parameter	Value / Note
Filtration Rating	≤10 μm

Flow and Restriction

Parameter	Value / Note
Rated Air Flow	Matched to NG R-Series 30–37 kW platform displacement; 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 Range	From new-element initial restriction to clogging alarm value
Alarm / Final Restriction	Per compressor intake vacuum gauge reading and controller alarm
Pressure Drop vs. Energy	Every 1 kPa increase in intake restriction raises compressor energy consumption by approximately 1%

Pressure drop and energy relationship

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

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 the 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 extra electricity cost far exceeds the price of one filter element. This is the engineering basis for the factory-set differential pressure alarm.

Standard Maintenance and Installation Steps

Single-person operation, 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 assembly 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 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 upstream oil carryover 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 2,000-hour interval with the air filter. Inspect it now: if clogged or heavily dusted, replace it at the same time. Criterion: media intact, no severe dust buildup.

6. Install the new element and confirm sealing
   Align 54672522 with the housing outlet end and push in, all the way. Confirm the radial seal ring is evenly compressed, with no pinched material or skewing. Criterion: element face flush with housing, uniform seal ring 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 properly seated.

Installation rule: Do not start the compressor until 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 ring and housing — equivalent to running with no filter.

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 R30 and R37 air filter the same?
Yes. 54672522 fits both R30 (30 kW) and R37 (37 kW). The difference between them is motor power and displacement; the 30–37 kW platform uses identical housing and element.

Will it fit an R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Different power platforms have different housing dimensions — cross-platform installation 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. If site dust is consistently high, add a high-dust pre-filter kit (24737298 / 24737306) — when the pre-filter layer is spent, replace only the pre-filter to extend the main element's life.

What else should be replaced with the air filter?
Parts sharing the 2,000-hour interval: oil filter 54672654, oil separator 54749247, and breather filter 39123111. These share the same interval as the air filter. Replace them together to avoid staggered maintenance cycles and repeated downtime.

Is there a service kit containing these parts?
Yes. 2,000-hour kit 24730897 (fixed-speed 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, 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. Blowing with compressed air only removes surface dust; deep fine particles cannot be removed. Back-blow pressure can also fracture 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) rising intake vacuum gauge reading; (2) controller service-due alarm; (3) media surface completely covered with dust after removal, with no visible pleats; (4) reduced discharge flow with increased energy consumption. Any one signal means replace.

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 identification and 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.

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 vs. variable speed and whether a dryer is fitted do not affect air filter selection.
• 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 compressor nameplate model is not in the table above, provide a photo of the nameplate and the full model number. We will cross-reference by part number to confirm before ordering.

2,000-Hour Service Kit	24730897	Service kit for fixed and variable speed	Order all same-interval wear parts at once to reduce downtime
4,000-Hour Service Kit	24730939 (fixed) / 24766123 (variable)	Major service kit	Schedule per compressor running hours
High-Dust Pre-Filter Kit	24737298 / 24737306	Additional pre-filter layer for high-dust sites	Replace only the pre-filter when spent to extend main element life

Paired replacement recommendation: Air filter, oil filter, and oil separator share the 2,000-hour interval. Replace them together to avoid staggered maintenance cycles. For dusty sites, prioritize installing the high-dust pre-filter kit — pre-filter cost is far lower than the main element, and replacement is faster.
