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

Product Overview

54672522 is the inlet air filter element for Ingersoll Rand NG R-Series (Next Generation R-Series) 30–37 kW screw air compressors. It installs inside the external air cleaner assembly (part 54652565), upstream of the airend inlet. As the first filtration barrier, its condition directly affects the service life of the oil separator, oil filter, and lubricant.

One part number covers four models: R30I, R30N, R37I, and R37N. Both 30 kW and 37 kW, fixed-speed (N) and variable-speed (I) configurations share the same element. No differentiation by power or drive type is required at procurement.

Technical Specifications

Filtration Performance

Parameter	Value / Note
Filtration Rating	≤10 μm
Filtration Efficiency	≥99% for particles ≥5 μm
Filter Class	Not classified under EN 779 (HVAC); tested per ISO 5011 for efficiency, restriction, and dust holding
Dust Holding Capacity	Approx. 900 g

Flow and Restriction

Parameter	Value / Note
Rated Flow	Matched to NG R-Series 30–37 kW displacement; one element per compressor
Face Velocity	Approx. 0.036 m/s
Initial Pressure Drop	Inlet vacuum should remain below 0.05 bar (5 kPa) after installation
Alarm / Final Restriction	Per inlet vacuum gauge and controller alarm
Restriction vs. Energy	Each 1 kPa increase in inlet restriction raises energy consumption by approx. 1%

Restriction and energy relationship: At 0.7 MPa discharge and 101.3 kPa atmospheric pressure, theoretical compression ratio rises from 7.91 (clean) to 8.41 at 6 kPa restriction, increasing relative energy consumption by approximately 6.3%. For R-Series units running over 6,000 hours annually, this energy penalty far exceeds the cost of an element — the engineering basis for the factory pressure-drop alarm.

Standard Applicability	The ISO 29xx / 37xx series are hydraulic filter test methods. If a supplier only provides hydraulic filter standards, request ISO 5011 or OEM specification.

Installation Steps

One person, approx. 20 minutes.

1. Shut down, depressurize, lock out/tag out. Disconnect main power and apply lockout/tagout. Wait until controller shows 0 bar. Criterion: gauge at zero, no residual air flow noise.
2. Open the air cleaner housing. The external assembly is on the R-Series enclosure. Release end-cover latches or bolts. Criterion: latches free, cover not deformed.
3. Remove old element and inspect. Pull the element straight out and observe dust distribution. Criterion: uniform gray-brown dust is normal; oily residue indicates upstream oil carryover — investigate.
4. Clean housing interior. Wipe inner walls and bottom with a dry, lint-free cloth. Do not blow compressed air into the housing — it drives dust into the intake. Criterion: no loose dust; in humid areas, check for condensation at the bottom.
5. Check breather filter. The breather filter (part 39123111) shares the 2,000-hour interval. Inspect now; replace if clogged or heavily loaded. Criterion: media intact, no severe dust loading.
6. Install new element and confirm seal. Push 54672522 into the housing outlet end fully. Confirm the radial seal ring is evenly compressed, not pinched or skewed. Criterion: element face flush with housing, uniform seal compression marks.
7. Reassemble, reset timer, verify. Refit cover and tighten latches. Reset the air filter service timer on the controller. Start and run at idle for 5 minutes. Criterion: inlet vacuum stable below 0.05 bar (5 kPa) — indicates good seal. If vacuum is high, recheck seal seating.

Critical rule: Do not start the compressor until the element is fully seated and the seal is compressed. If a radial seal is not pushed home, air bypasses directly between seal and housing — equivalent to running without a filter.

FAQ

Which models use 54672522?
All four NG R-Series 30–37 kW models: R30I, R30N, R37I, R37N. Fixed-speed (N) and variable-speed (I) share the same element. R30, R37, R30IE, and R37IE also use this part number.

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

Can it be used on R45 or R55?
No. R45–R75 uses 54672530; R90–R110 uses 23429822. Different power platforms have different housing dimensions and cannot be interchanged.

How often should it be replaced?
Standard conditions: 2,000 hours or 3 months, whichever comes first. In high-dust environments (cement, quarry, mining), shorten to approx. 1,500 hours. For persistently high dust, add the high-dust pre-filter kit (24737298 / 24737306) — replace only the pre-filter when loaded, extending main element life.

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

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

What lubricant is recommended?
Ingersoll Rand Ultra Coolant, part 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. Compressed-air back-blowing removes only surface dust; deep fine particles remain. Back-pressure can also damage media fibers or distort pleat spacing, creating invisible channels. Reusing a cleaned element is a "looks clean, actually failed" condition — risk outweighs benefit.

How do I know it needs replacement?
Four signals: (1) inlet vacuum gauge reading rises; (2) controller shows service due; (3) media surface completely covered with dust, original pleats not visible; (4) discharge flow drops while energy consumption rises. Replace on any signal.

Is it genuine? How to verify?
The 54672522 described here is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand authentication and warranty. Order by part number — the part number is the only unambiguous identifier. Do not order based solely on "fits R30/R37" or visual similarity.

Notes:

• All 8 models above use this product (NG R-Series 30–37 kW platform). Drive type or dryer presence does not affect air filter selection.
• Cross-power-platform interchange is not possible. Other power ranges in the same series:

Power Platform	Air Filter Part No.
R45–R75 (45–75 kW)	54672530
R90–R110 (90–110 kW)	23429822

• If your compressor nameplate model is not listed, provide a nameplate photo and full model number. We will verify by part number before order.

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