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 platform-wide commonality: R30I, R30N, R37I, and R37N all use 54672522. Fixed-speed (N) and variable-speed (I) configurations share the same element, so buyers do not need to differentiate by power rating or drive type.

Flow & Restriction

Parameter	Value / Note
Rated Flow	Matched to NG R-Series 30–37 kW displacement; 1 element per unit
Face Velocity	Approx. 0.036 m/s
Initial Pressure Drop	After new element installation, intake vacuum should stabilize below 0.05 bar (5 kPa)
Alarm / Final Restriction	Per unit intake vacuum gauge and controller alarm setpoint
Pressure Drop vs. Energy	Each 1 kPa rise in intake restriction increases unit energy consumption by approx. 1%

Engineering Note: As the element loads from new to heavily restricted (0 → 6 kPa), unit energy consumption rises by approximately 6%. R-Series units commonly run over 6,000 hours per year, making the added electricity cost far exceed the price of an element — this is the engineering basis for the factory pressure-drop alarm.

Commonly Cited Test Standards	ISO 2941 / 2942 / 2943 / 3723 / 3724 / 3968
Standard Applicability 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.

Standard Maintenance & Installation Steps

One-person operation, approximately 20 minutes.

1. Shut down, depressurize, lockout/tagout
   Disconnect and lock out the main power. Wait until the controller shows 0 bar system pressure. Criterion: 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 latches or bolts. Criterion: latches free of seizure, 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 loading is normal; oily residue indicates upstream oil carryover and requires investigation.

4. Clean the housing interior
   Wipe the inner walls and base with a dry, lint-free cloth. Do not blow compressed air into the housing (it drives dust into the intake passage). Criterion: no loose dust on inner walls; in humid areas, also check for condensate at the housing base.

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 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 pinching or skewing. Criterion: element face flush with housing, uniform seal ring compression marks.

7. Reassemble, reset the timer, and verify
   Refit the end cover and secure the latches. Reset the air filter service timer on the controller. Start the unit and run at idle for 5 minutes. Criterion: intake vacuum stable below 0.05 bar (5 kPa), indicating a proper seal; if vacuum is high, check that the seal ring is seated correctly.

Installation Rule: Do not start the unit before the element is fully seated and the seal ring is compressed. With a radial-seal design, if not pushed fully home, air bypasses directly through the gap between the seal ring and 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, 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 30–37 kW platform shares the same filter housing and element.

Can it be used on R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Filter housing dimensions differ across power platforms; 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 levels are consistently high, add the high-dust pre-filter kit (24737298 / 24737306) so only the pre-filter is replaced when it loads, extending main element life.

What else should be replaced with the air filter?
Parts sharing the 2,000-hour service 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 and repeated downtime.

Is there a service kit containing these parts?
Yes. 2,000-hour kit 24730897 (universal for fixed and variable speed), 4,000-hour fixed-speed kit 24730939, and 4,000-hour variable-speed kit 24766123.

Which 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. Back-blowing with compressed air only removes surface dust; deep fine particles cannot be cleared. 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 with more risk than benefit.

How do I know it is time to replace?
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 original pleats are not visible; ④ discharge flow drops while energy consumption rises. Any one signal warrants replacement.

Is this a genuine part? How do I verify?
The 54672522 described on this page is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand authenticity 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.
