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 rotary screw air compressors. It is installed inside the external air cleaner assembly, upstream of the airend intake. 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 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 time of purchase.

Flow and Restriction Data

Parameter	Value / Note
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	With a new element installed, intake vacuum should stabilize below 0.05 bar (5 kPa)
Operating Differential Range	From initial restriction of a new element to the clogging alarm setpoint
Alarm / Final Restriction	Per compressor intake vacuum gauge reading and controller alarm
Pressure Drop vs. Energy	Each 1 kPa increase in intake restriction raises compressor energy consumption by approximately 1%

Restriction and energy relationship

Rising intake restriction lowers intake pressure and air density, forcing the compressor to work harder to maintain set discharge pressure and flow, which increases specific power. Based on 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure, theoretical compression ratio calculations show:

Intake 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 → 6 kPa), compressor energy consumption rises by approximately 6%. R-Series compressors commonly run over 6,000 hours per year, and the extra electricity cost far exceeds the price of one filter element—this is the engineering rationale behind the OEM differential pressure alarm.

Standard Maintenance and Installation Steps

One person, approx. 20 minutes.

1. Shut down, depressurize, lockout/tagout
   Disconnect and lock out the 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 cap latches or bolts. Criterion: latches free of seizure, end cap not deformed.

3. Remove the old element and inspect its condition
   Lift out the old element vertically and observe dust distribution and surface condition. Criterion: uniform gray-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 (it will drive 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 as the air filter. Inspect it now: if clogged or heavily 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 in, all the way. Confirm the radial seal ring is evenly compressed around the circumference, with no pinching or skewing. Criterion: element face flush with housing, uniform seal ring compression marks.

7. Reassemble, reset the timer, and verify
   Refit the end cap and tighten latches. On the controller, reset the air filter service timer. 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.

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 will bypass directly between the seal ring and housing—equivalent to running with no filter.

Frequently Asked Questions

Which models use 54672522?
All four models in the NG R-Series 30–37 kW platform: R30I, R30N, R37I, R37N. Both fixed-speed (N) and variable-speed (I) configurations use 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 filter housing and element are identical across the 30–37 kW platform.

Can it be used on 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 is not possible and will not 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, quarrying, or mining, shorten to approximately 1,500 hours. If site dust is persistently high, a high-dust pre-filter kit (24737298 / 24737306) can be added—when the pre-filter layer fails, only the pre-filter needs replacement, extending main element life.

What else should be replaced with the air filter?
Parts sharing the same 2,000-hour service interval include: oil filter 54672654, oil separator 54749247, and breather filter 39123111. These share the same interval as the air filter; replacing them together avoids 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. Back-blow pressure can also 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 is time to replace?
Four signals: ① rising intake vacuum gauge reading; ② controller service-due alarm; ③ after removal, the media surface is completely covered with dust and the original pleat pattern is not visible; ④ decreasing discharge flow with increasing energy consumption. Any one signal indicates replacement is due.

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 markings and warranty. When purchasing, rely on the part number itself—the part number is the only unambiguous identifier. Do not order based solely on "fits R30/R37" or visual similarity.

Lubricant (Ultra Coolant)	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	Service kit for both fixed and variable speed	Supplies all same-interval wear parts in one order, reducing downtime
4,000-Hour Service Kit	24730939 (fixed) / 24766123 (variable)	Major service kit	Schedule according to compressor running hours
High-Dust Pre-Filter Kit	24737298 / 24737306	Add-on pre-filter layer for sites with excessive dust	When the 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. At dusty sites, prioritize adding the high-dust pre-filter kit—pre-filter cost is far lower than the main element, and replacement is faster.
