Product Overview
88111901 air filter element is a genuine Ingersoll Rand inlet filter designed for SSR M37, SSR M37 B, SSR M45 and MM45 series screw air compressors. The element uses high-efficiency synthetic fiber media to block dust and particulate matter from entering the screw airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.
As an original inlet filtration component for the Ingersoll Rand SSR range, 88111901 is manufactured to Ingersoll Rand global technical standards. It combines low initial pressure drop, high dust holding capacity and straightforward installation, making it a core consumable for routine maintenance of SSR M37–M45 compressors.

7. Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing

- GB/T 6165: Test methods for air filter performance (efficiency and resistance)
Maintenance and Installation
Replacement Interval
- Standard conditions: every 4,000 hours or 8–12 months, whichever comes first
- High-dust conditions (mining, construction materials, woodworking): every 2,000–3,000 hours
- Replace immediately if media is blackened, heavy dust loading is visible, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate: switch off main power, apply lockout/tagout (LOTO), confirm the compressor has fully stopped.
- Open the filter housing: release the retaining nut or clips and remove the cover.
- Remove the old element: pull out the old 88111901 element and check whether the center gasket remains in the housing groove.
- Clean the housing: wipe the inner walls and sealing surfaces with a clean cloth. Never reverse-blow and reuse an old element.
- Inspect the new element: verify part number 88111901, check media for damage, pleat deformation, cracked end caps or aged gaskets.
- Install the new element: slide it onto the center stud, ensuring the gasket seats evenly top and bottom without distortion.
- Refit the cover: replace the cover and tighten the nut or clips evenly for a gap-free seal.
- Start-up check: start the compressor and listen for air leaks at the filter housing; confirm normal operation.
FAQ
Q1: Is 88111901 a genuine Ingersoll Rand part?
A: Yes, 88111901 is a genuine Ingersoll Rand component manufactured to Ingersoll Rand global technical standards and intended for SSR M37/M45 series compressors.
Q2: Which compressors does 88111901 fit?
A: It fits Ingersoll Rand SSR M37, SSR M37 B, SSR M45 and MM45 series screw compressors. If you are unsure, provide the machine serial number and we will confirm the correct part.
Q3: How do I know when to replace the air filter?
A: Replace when: (1) visual inspection shows blackened or heavily loaded media; (2) operating differential pressure reaches the 550 Pa alarm value; or (3) the 4,000-hour or 8–12 month interval is reached.
Q4: What happens if the filter is too dirty?
A: A clogged element restricts inlet air, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear, seal ageing, higher oil carryover and potentially airend failure.
Q5: Can 88111901 be interchanged with other SSR filters?
A: Different SSR power classes use different element dimensions and flow ratings, so they are not freely interchangeable. Always confirm the correct part number using the machine serial number.
