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 installed inside the external air cleaner assembly, upstream of the airend intake, and acts as the first filtration barrier protecting the oil separator, oil filter, and lubricant downstream.

A key procurement advantage: one part number serves four models — R30I, R30N, R37I, and R37N. Both 30 kW and 37 kW platforms, and both fixed-speed (N) and variable-speed (I) configurations, share the same element. No need to differentiate by power or drive type when ordering.

Technical Parameters

Filtration Performance

Parameter	Value / Notes
Filtration Rating	≤10 μm

Filter Class	Not classified under EN 779 (HVAC); characterized per ISO 5011 by efficiency, restriction, and dust holding capacity
Dust Holding Capacity	Approx. 900 g

Flow and Pressure Drop

Parameter	Value / Notes
Rated Air Flow	Matched to NG R-Series 30–37 kW platform; 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 new element installation
Alarm / Final Restriction	Per compressor intake vacuum gauge and controller alarm setpoint
Pressure Drop vs. Energy	Every 1 kPa increase in intake restriction adds approx. 1% to compressor energy consumption

Why pressure drop matters: Rising intake restriction reduces intake pressure and air density. To maintain set discharge pressure and flow, the compressor must work harder, increasing specific power. At 0.7 MPa discharge and 101.3 kPa atmospheric pressure, theoretical compression ratio calculations show: 0 kPa (new) = baseline; 2 kPa = +2.0%; 4 kPa = +4.1%; 6 kPa = +6.3%. Over 6,000+ annual running hours typical for R-Series units, this energy penalty far exceeds the cost of a filter element — the engineering basis for OEM pressure-drop alarms.

Construction and Dimensions

Parameter	Value / Notes
Dimensions	OD 194 mm × ID 114 mm × H 399 mm
Media Height	367 mm (end structures approx. 32 mm total)

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

Installation and Maintenance Procedure

One person, approximately 20 minutes.

1. Shut down, depressurize, lock out/tag out. Disconnect main power and apply lockout/tagout. Wait until controller shows 0 bar system pressure. Criterion: 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 end-cap latches or bolts. Criterion: latches free of seizure, cap not deformed.
3. Remove old element and inspect. Lift out vertically 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 base with dry lint-free cloth. Do not blow compressed air into the housing (it drives dust into the intake). Criterion: no loose dust; in humid locations check for condensation at the base.
5. Check breather filter. Breather filter (P/N 39123111) shares the 2,000-hour interval. Inspect now: if clogged or heavily loaded, replace together. Criterion: media intact, no heavy dust loading.
6. Install new element and confirm seal. Align 54672522 with housing outlet and push fully home. Confirm radial seal ring is evenly compressed, no pinching, no skewing. Criterion: element face flush with housing, uniform seal impression around circumference.
7. Reassemble, reset timer, verify. Refit end cap and secure latches. Reset the air filter service timer on the controller. Start compressor and run at idle for 5 minutes. Criterion: intake vacuum stabilizes below 0.05 bar (5 kPa), confirming a 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 ring is properly compressed. With a radial seal, if not pushed fully home, air bypasses directly between seal 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, R37N. Fixed-speed (N) and variable-speed (I) share the same element. 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 is motor power and displacement; the 30–37 kW platform shares the same housing and element.

Will it fit R45 or R55?
No. R45–R75 uses 54672530; 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. High-dust environments (cement, quarry, mining) should shorten to approx. 1,500 hours. Where dust is persistently high, add a high-dust pre-filter kit (24737298 / 24737306) — replace only the pre-filter when it loads, 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 cycles and repeated downtime.

Is there a service kit containing these?
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 should be used?
Ingersoll Rand Ultra Coolant, P/N 38459582, for all R-Series screw compressors. Available in 5 L, 20 L, and 55-gallon sizes.

Can I blow out a dirty element and reuse it?
Not recommended. This is a radial-seal pleated paper element designed for single use. Compressed-air back-blowing only removes surface dust; deep fine particles remain. Back-blow pressure can also fracture media fibers or distort pleat spacing, creating invisible channels. Reusing a cleaned element means it looks clean but has failed — risk exceeds any savings.

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

Is this a genuine part? How to verify?
The 54672522 shown here is the Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand anti-counterfeit identification and warranty. Always order by part number — the part number is the only unambiguous identifier. Do not order based only on "fits R30/R37" or visual similarity.

Compatible Models

No.	Model	Power	Drive Type

Key notes:

• All eight models above use this element — they belong to the NG R-Series 30–37 kW platform. Drive type and dryer configuration do not affect air filter selection.
• Cross-platform interchange is not possible. Air filter part numbers for other power platforms 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 listed, provide a nameplate photo and full model number. We will cross-reference by part number before you order.

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