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 is mounted inside the external air cleaner assembly, upstream of the airend inlet. 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.

This part number is shared across four models on the same platform: R30I, R30N, R37I, and R37N. Both 30 kW and 37 kW ratings, and both fixed-speed (N) and variable-speed (I) configurations, use the same element. No differentiation by power or drive type is required at procurement.

Technical Parameters

Filtration Performance

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

Flow and Restriction

Parameter	Value
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	After new element installation, inlet vacuum should stabilize below 0.05 bar (5 kPa)
Operating Differential Range	From new-element initial restriction to clogging alarm threshold
Alarm / Final Restriction	Per compressor inlet vacuum gauge and controller alarm
Pressure Drop vs. Energy	Each 1 kPa increase in inlet restriction raises compressor energy consumption by approx. 1%

Pressure Drop and Energy Consumption

Rising inlet restriction lowers inlet pressure and density. To maintain set discharge pressure and flow, the compressor must do more work, increasing specific power. Based on 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure:

Inlet 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 progresses from new to heavily clogged (0 to 6 kPa), compressor energy consumption rises by approximately 6%. R-Series compressors commonly run over 6,000 hours per year — the added electricity cost far exceeds the price of one element. This is the engineering basis for the factory-set differential pressure alarm.

Dimensions and Installation

Parameter	Value

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 and Installation Steps

One person, approximately 20 minutes.

1. Shut down, depressurize, lock out/tag out
   Disconnect and lock out main power. 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 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 is normal; oily residue indicates an upstream oil carryover issue that 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 (it drives dust into the intake passage). Criterion: no loose dust on inner walls; in humid areas, also check for condensation at the housing bottom.

5. Check the breather filter
   The breather filter (part number 39123111) shares the same 2,000-hour interval as the air filter. Inspect now: replace together if clogged or heavily dust-loaded. Criterion: media intact, no severe dust accumulation.

6. Install the new element and confirm sealing
   Align 54672522 with the housing outlet end and push in fully. Confirm the radial seal ring is uniformly compressed around its circumference, with no pinching or skewing. Criterion: element face flush with housing, uniform seal impression around the perimeter.

7. Reassemble, reset timer, and verify
   Refit the end cover and tighten latches. Reset the air filter service timer on the controller. Start the compressor and run at idle for 5 minutes. Criterion: inlet vacuum stabilizes below 0.05 bar (5 kPa), indicating a good seal; if vacuum is high, check seal ring seating.

Installation rule: Do not start the compressor before the element is seated and the seal ring is compressed. If a radial-seal element is not pushed fully into position, air bypasses directly 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, 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 uses identical filter housing and element.

Can it be used on 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 or seal.

How often should it be replaced?
2,000 hours or 3 months under standard conditions, whichever comes first. In high-dust environments such as cement, quarry, or mining, shorten to approximately 1,500 hours. If site dust is persistently high, add the high-dust pre-filter kit (24737298 / 24737306) to replace only the pre-filter layer and extend main element life.

What else should be replaced with the air filter?
Same 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 and repeated downtime.

Are there service kits 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.

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. Compressed air back-blowing only removes surface dust; deep fine particles remain. Back-blow pressure can also rupture media fibers or deform pleat spacing, creating invisible channels. A cleaned element is "visually clean but functionally failed" — the risk outweighs the benefit.

How do I know it needs replacement?
Four signals: ① inlet vacuum gauge reading rises; ② controller indicates service due; ③ removed element surface fully covered with dust, original pleat pattern no longer 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 here is an Ingersoll Rand OEM part number. Genuine parts carry Ingersoll Rand anti-counterfeit 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.

Reading the table

• All eight models above use this product, on the NG R-Series 30–37 kW platform. Fixed or variable speed, with or without dryer, does not affect air filter selection.
• Cross-platform interchange is not possible. 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 listed above, provide a photo of the nameplate and full model number. We will confirm by part number before order placement.

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