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

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, and acts as the first filtration barrier for the compressed air system. Its condition directly affects the service life of the downstream oil separator, oil filter, and lubricant.

One part number covers the entire 30–37 kW platform: R30I, R30N, R37I, and R37N all use 54672522. Both fixed-speed (N) and variable-speed (I) configurations share the same element, so no differentiation by power or drive type is required at the point of purchase.

Technical Parameters

Filtration Performance

• Filtration rating: ≤10 μm
• Filtration efficiency: ≥99% for particles ≥5 μm
• Filter class: Not classified under EN 779 HVAC standards; 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
• Filtration 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 pressure drop: per the compressor intake vacuum gauge reading and controller alarm
• Pressure drop vs. energy: every 1 kPa increase in intake restriction raises compressor energy consumption by approximately 1%

Engineering note: As intake restriction rises from 0 kPa (new element) to 6 kPa (heavily loaded), compressor energy consumption increases by approximately 6%. R-Series units commonly run 6,000+ hours per year, so this added electricity cost far exceeds the price of an element — this is the engineering basis for the factory pressure-drop alarm.

Construction and Dimensions

• Dimensions: 194 mm OD × 114 mm ID × 399 mm overall height
• Media pack height: 367 mm (end structures account for approx. 32 mm)
• Type: 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
• Installation interface: radial push-in, fits the outlet end of air cleaner assembly 54652565
• Seal type: radial seal

Sourcing tip: When cross-checking replacements, verify all three dimensions — 194 mm OD, 114 mm ID, 399 mm overall height. This element uses a radial seal; the seal ring sits on the outer circumference of the element end and must be pushed fully home with even circumferential compression.

Materials

• Media: imported wood-pulp filter paper (industry-common HV or Ahlstrom media)
• Media weight: approx. 130 g/m²
• Inner/outer support: galvanized steel perforated cage (inner cage + outer guard)

• Seal: radial seal ring (oil-resistant rubber)
• Bonding layer: 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 test)
• Collapse resistance: element must withstand intake alarm differential pressure without collapsing
• Special features: no flame-retardant, anti-static, or special coating noted for this part number

Service Life and Storage

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

Standards

• Applicable product standard: ISO 5011 (inlet air cleaners for internal combustion engines and compressors — performance testing), evaluated by filtration efficiency, intake restriction, and dust holding capacity
• Commonly cited test standards: ISO 2941 / 2942 / 2943 / 3723 / 3724 / 3968
• Standard applicability 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 or the OEM specification sheet.

Installation and Maintenance Steps

One person, approx. 20 minutes.

1. Shut down, depressurize, lock out/tag out. Disconnect and lock out the main power. Wait until the controller shows system pressure at 0 bar. Criterion: pressure 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 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: even grey-brown dust loading is normal; oily residue on the surface indicates upstream oil carryover and should be investigated.
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 — this drives dust into the intake passage. Criterion: no loose dust on inner walls; in humid areas, also check for condensate 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; replace if clogged or heavily loaded. 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 fully home; confirm the radial seal ring is evenly compressed with no trapped material or skew. Criterion: element face flush with housing, uniform seal ring compression marks.
7. Reassemble, reset the timer, and verify. Refit the end cover and tighten the 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 seated.

Installation rule: Do not start the compressor before the element is fully seated and the seal ring is compressed. With a radial seal, if the element is not pushed fully home, air bypasses directly through the gap between seal ring and housing — equivalent to running with no 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 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 between the two is motor power and displacement; the air cleaner housing and element on the 30–37 kW platform are identical.

Can it be used on R45 or R55?
No. R45–R75 uses 54672530, and R90–R110 uses 23429822. Filter housings differ across power platforms and 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 approx. 1,500 hours. Where dust levels are persistently high, a high-dust pre-filter kit (24737298 / 24737306) allows replacing only the pre-filter layer to extend main element life.

What else should be replaced with the air filter?
Parts sharing the 2,000-hour interval: oil filter 54672654, oil separator 54749247, and breather filter 39123111. These share the same interval as the air filter; inspect and replace together to avoid staggered maintenance and repeated downtime.

Is there a service kit covering 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. Reverse blowing with compressed air only removes surface dust; deep fine particles cannot be removed, and reverse pressure can rupture fibers or deform pleat spacing, creating invisible channels. Reusing a cleaned element means it looks clean but has actually failed — the risk outweighs the benefit.

How do I know it needs replacing?
Four signals: (1) intake vacuum gauge reading rises; (2) controller indicates service due; (3) after removal, the media surface is fully covered with dust and the original pleats are not visible; (4) discharge flow drops while energy consumption rises. Any one signal calls for replacement.

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 marking and warranty. Always order by the part number itself — the part number is the only unambiguous identifier. Do not order based only on "fits R30/R37" or visual similarity.

Reading notes

• All eight models above use this product; they belong to the NG R-Series 30–37 kW platform. Fixed vs. variable speed and dryer configuration do not affect air filter selection.
• Not interchangeable across power platforms. 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 unit nameplate model is not listed, provide a photo of the nameplate and the full model number; we will verify by part number before you order.

Related Parts

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

• 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, protecting bearings and rotors. Replace together with the air filter; check for oil seepage at the sealing surface afterward.
• Oil separator — 54749247 — separates oil mist from compressed air and returns oil, controlling discharge oil carryover. Check the oil return line for blockage during replacement.
• Breather filter — 39123111 — balances pressure in the oil separator tank and prevents external dust from entering the oil circuit. Inspect together with the air filter; replace if clogged.
• Ultra Coolant lubricant — 38459582 — standard coolant for R-Series screw compressors, providing lubrication and sealing. Test oil per compressor requirements; avoid mixing with other brands.
• 2,000-hour service kit — 24730897 — for both fixed and variable speed. Supplies all same-interval wear parts in one order, reducing downtime.
• 4,000-hour service kit — 24730939 (fixed speed) / 24766123 (variable speed) — major service kit. Schedule according to operating hours.
• High-dust pre-filter kit — 24737298 / 24737306 — additional pre-filter layer for sites with excessive dust. Replace only the pre-filter when loaded, extending main element life.

Paired replacement advice: Air filter, oil filter, and oil separator share the 2,000-hour interval. Replacing them together avoids staggered maintenance. For dusty sites, add the high-dust pre-filter kit — pre-filter cost is far lower than the main element and replacement is faster.
