Ingersoll Rand 54672522 Air Filter | NG R-Series 30–37 kW OEM Part

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 sits inside the external air cleaner assembly, upstream of the airend intake, and acts as the first filtration barrier for the compressed air system. Its condition directly affects how long the downstream oil separator, oil filter, and lubricant will last.

A key procurement advantage: one part number covers four models on the same platform. R30I, R30N, R37I, R37N all use 54672522 — both 30 kW and 37 kW, both fixed-speed (N) and variable-speed (I) configurations. No need to distinguish by power or drive type when ordering.

Technical Parameters

Filtration Performance

• Filtration rating: ≤10 μm
• Filtration efficiency: ≥99% for particles ≥5 μm
• Filter class: Not classified under EN 779 (HVAC filter standard); air filter elements are characterized per ISO 5011 by efficiency, intake restriction, and dust holding capacity
• Dust holding capacity: approx. 900 g

Flow and Pressure Drop

• Rated 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 installing a new element, intake vacuum should stabilize below 0.05 bar (5 kPa)
• Alarm / final resistance: per compressor intake vacuum gauge and controller alarm setpoint
• Energy relationship: every 1 kPa increase in intake restriction raises compressor energy consumption by approximately 1%

Why pressure drop matters: As intake restriction rises, intake pressure and density fall, and the compressor must work harder to maintain discharge pressure and flow. Based on a 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure, theoretical compression-ratio calculations show: 0 kPa restriction = baseline; 2 kPa = +2.0% energy; 4 kPa = +4.1%; 6 kPa = +6.3%. For an R-Series compressor running 6,000+ hours per year, the extra electricity cost far exceeds the price of a filter element — which is exactly why the factory sets a differential-pressure alarm.

Dimensions and Installation

• Overall dimensions: OD 194 mm × ID 114 mm × overall height 399 mm
• Media height: 367 mm (end structures total approx. 32 mm)
• Construction: Pleated radial-seal cylindrical element, primary/outer element
• Effective filtration area: approx. 3.0 m²
• Pleat count: approx. 101
• Pleat spacing: approx. 4.8 mm
• Mounting interface: radial push-in, installed at outlet end of air cleaner assembly (54652565)
• Seal type: Radial seal

Procurement tip: When cross-checking replacements, compare all three dimensions — OD 194 mm, ID 114 mm, overall height 399 mm. This is a radial-seal element; the seal sits on the outer circumference of the element end. Push it fully into position and confirm the seal is evenly compressed around its circumference.

• Media basis weight: approx. 130 g/m²
• Inner/outer support: galvanized steel perforated cage (inner cage + outer guard)
• End caps: metal end caps (galvanized steel) with polyurethane adhesive
• Seal: radial seal ring (oil-resistant rubber)
• Bonding: polyurethane (PU) hot-melt adhesive

Operating Conditions

• Operating temperature: −10 to +100 °C
• Relative humidity: ≤80% RH, non-condensing
• Burst strength: media burst strength approx. 200–400 kPa (per ISO 2758 paper burst strength test)
• Collapse resistance: element must withstand compressor intake alarm differential pressure without collapsing
• Special features: no flame-retardant, anti-static, or special coating markings on this model

Service Life and Maintenance

• Service life: 2,000 hours or 3 months, whichever comes first
• High-dust environments: shorten to approx. 1,500 hours, or install a high-dust pre-filter kit
• Shelf life: approx. 2–3 years (unopened, dry, ventilated storage)

Standards

• Applicable product standard: ISO 5011 (inlet air cleaning equipment for internal combustion engines and compressors — performance testing), evaluating efficiency, intake restriction, and dust holding capacity
• Commonly cited test standards: ISO 2941 / 2942 / 2943 / 3723 / 3724 / 3968
• Note: the ISO 29xx / 37xx series are generic test methods for hydraulic fluid power filter elements. If a supplier can only provide hydraulic filter standards, request ISO 5011 data or the OEM specification sheet.

Standard Maintenance and Installation Steps

One person, approx. 20 minutes.

1. Shut down, depressurize, lockout/tagout. Disconnect main power and apply lockout/tagout. Wait until the controller shows 0 bar system pressure. Criterion: gauge reads zero, no residual air flow noise.
2. Open the air cleaner housing. The air cleaner assembly is external, mounted on the R-Series enclosure. Release the end-cover latches or bolts. Criterion: latches not seized, 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 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 — it will drive 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. Inspect it now: if clogged or heavily dust-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 it in fully. Confirm the radial seal ring is evenly compressed around its circumference, with no trapped material and no skewing. Criterion: element face flush with housing, uniform seal compression marks.
7. Reassemble, reset the 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: intake vacuum stabilizes below 0.05 bar (5 kPa), indicating a good seal. If vacuum is high, check that the seal ring is properly seated.

Critical rule: Do not start the compressor until the element is fully seated and the seal is compressed. With a radial-seal design, if the element is not pushed fully home, air bypasses directly through the gap between seal and housing — equivalent to running with no filter at all.

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. Additionally, 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 air cleaner housing and element.

Can it be used on an R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Different power platforms have different air cleaner housing dimensions — 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, quarry, or mining, shorten to approx. 1,500 hours. If site dust is persistently high, a high-dust pre-filter kit (24737298 / 24737306) can be installed; when the pre-filter layer fails, replace only the pre-filter to extend main element life.

What else should be replaced at the same time?
Parts on the same 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 cycles and repeated downtime.

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

What 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. Back-blowing with compressed air only removes surface dust; deep fine particles cannot be removed, and back-blow pressure can rupture media fibers or deform pleat spacing, creating invisible channels. Reusing a cleaned element is a "looks clean, actually failed" condition — the risk outweighs the benefit.

How do I know it's 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 means replace.

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 anti-counterfeit identification and warranty. Always verify 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 notes: All eight models above use the product on this page — they belong to the NG R-Series 30–37 kW platform. Fixed vs. variable speed and whether a dryer is included do not affect air filter selection. Cross-power-platform interchange is not possible. Air filter part numbers for other power ranges in the same series: R45–R75 (45–75 kW) = 54672530; R90–R110 (90–110 kW) = 23429822. If your compressor nameplate model is not listed above, provide a nameplate photo and full model number, and we will cross-reference by part number before ordering.

Related Components

In the R-Series 30–37 kW platform's intake and lubrication system, the following parts share the same service interval as the air filter (part numbers from the R30I/R30N/R37I/R37N parts manual):

Component	Part Number	Function	Inspection Points
Air cleaner assembly	54652565	Housing that holds and secures the air filter element	Check latches, sealing surfaces, and outlet end for deformation
Oil filter	54672654	Removes wear debris and sludge from lubricant; protects bearings and rotors	Replace with air filter; check sealing surface for leaks after replacement
Oil separator	54749247	Separates oil mist from compressed air and returns oil; controls oil carryover	Check oil return line for blockage when replacing
Breather filter	39123111	Balances pressure in the oil separator tank; prevents external dust from entering the oil circuit	Inspect with air filter; replace if clogged
Lubricant (Ultra Coolant)	38459582	Standard coolant for R-Series screw compressors; lubricates and seals	Test oil per compressor requirements; avoid mixing with other brands
2,000-hour service kit	24730897	Service kit for both fixed and variable speed	Supplies all same-interval wear parts in one order; reduces downtime events
4,000-hour service kit	24730939 (fixed) / 24766123 (variable)	Major service kit	Schedule per compressor running hours
High-dust pre-filter kit	24737298 / 24737306	Additional pre-filter layer for high-dust sites	When pre-filter layer fails, replace only the pre-filter to extend main element life

Recommended replacement practice: The air filter, oil filter, and oil separator share the 2,000-hour interval. Replace them together to avoid staggered maintenance cycles. For high-dust sites, install the high-dust pre-filter kit first — pre-filter cost is far lower than the main element and replacement is faster.
