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 the service life of the downstream oil separator, oil filter, and lubricant.

A key advantage of this part number is shared coverage across four models on the same platform: R30I, R30N, R37I, and R37N all use 54672522. Both 30 kW and 37 kW, fixed-speed (N) and variable-speed (I) configurations, use the same element. No differentiation by power rating or speed control is required at the time of purchase.

Technical Specifications

Filtration Performance

• Filtration rating: ≤10 μm
• Filtration efficiency: ≥99% for particles ≥5 μm
• Filter class: Air intake filters are characterized per ISO 5011 by filtration efficiency, intake restriction, and dust holding capacity; the EN 779 HVAC filter classification system does not apply
• Dust holding capacity: approx. 900 g

Flow and Restriction

• Rated air flow: matched to NG R-Series 30–37 kW platform displacement; one element per compressor
• Filtration face velocity: approx. 0.036 m/s
• Initial pressure drop: intake vacuum should stabilize below 0.05 bar (5 kPa) after installing a new element
• Alarm/final restriction: according to the 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%

Engineering note: As the element loads from new to heavily restricted (0 → 6 kPa), compressor energy consumption rises by approximately 6% over the interval. R-Series compressors commonly run 6,000+ hours per year; the added electricity cost far exceeds the price of an element. This is the engineering basis for the factory-set differential pressure alarm.

• Commonly cited test standards: ISO 2941 / 2942 / 2943 / 3723 / 3724 / 3968
• Note: The ISO 29xx / 37xx series are general test methods for hydraulic fluid power filters. If a supplier can only provide hydraulic filter standards, request ISO 5011 or the OEM specification sheet

Installation and Maintenance Procedure

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 0 bar system pressure. Criterion: pressure 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 cap latches or bolts. Criterion: latches free of seizure, 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 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 regions, 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. 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 end and push in fully. 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 compression marks.
7. Reassemble, reset the timer, and verify. Refit the end cap and tighten 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 whether the seal ring is seated correctly.

Installation rule: Do not start the compressor before the element is fully seated and the seal ring is compressed. With a radial seal, if the element is not pushed fully home, air bypasses directly through the gap between seal and housing — equivalent to running without an element.

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 the two is motor power and displacement; 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; R90–R110 uses 23429822. Filter housing dimensions differ across power platforms; cross-platform installation will not fit and cannot 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, quarrying, or mining, reduce to approximately 1,500 hours. Where site dust is persistently high, a high-dust pre-filter kit (24737298 / 24737306) can be installed so that only the pre-filter is replaced when it loads, extending main element life.

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

Is there a service kit containing these parts?
Yes. 2,000-hour kit 24730897 (fixed and variable speed), 4,000-hour fixed-speed kit 24730939, 4,000-hour variable-speed kit 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 cannot be removed, and blow pressure can fracture media fibers or deform pleat spacing, creating invisible channels. Continued use after cleaning is a "looks clean, actually failed" condition with more risk than benefit.

How do I know it needs replacement?
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 pleats are not visible; ④ discharge flow drops while energy consumption rises. Replace on any one signal.

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 authentication markings and warranty. Always order by the part number itself — the part number is the only unambiguous identifier. Do not order based solely on "fits R30/R37" or visual similarity.
