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

- GB/T 14295: air filters
- GB/T 6165: air filter performance test methods (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, building materials, woodworking shops): every 2,000–3,000 hours
- Replace immediately if visual inspection shows dark or heavily loaded media, or if differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate: switch off the main compressor power, apply lockout/tagout (LOTO) and confirm the unit 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 wall and sealing face with a clean cloth. Never reverse-blow and reuse an old element.
- Inspect the new element: verify part number 88111901 and check for media damage, pleat deformation, cracked end caps or aged gaskets.
- Fit the new element: slide it onto the center stud, ensuring the gasket seats correctly top and bottom without tilting or twisting.
- Refit the cover: reinstall the cover and tighten the nut or clips evenly for a gap-free seal.
- Start-up check: start the compressor, listen for air leaks at the filter housing and confirm normal operation.
FAQ
Q1: Is the 88111901 a genuine original part?
A: The 88111901 is a genuine Ingersoll Rand replacement part, manufactured to Ingersoll Rand global technical standards and matched to SSR M37/M45 series compressors.
Q2: Which compressors does the 88111901 fit?
A: It fits Ingersoll Rand SSR M37, SSR M37 B, SSR M45 and MM45 series screw compressors. If you are unsure about your model, provide the machine serial number and we will confirm exact fitment.
Q3: How do I know when to replace the air filter element?
A: Replace it if: 1) visual inspection shows dark 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 has been reached.
Q4: What happens if the element is too dirty?
A: A clogged element restricts intake air, reducing discharge volume and raising specific power and energy consumption. In severe cases, dust enters the airend, causing rotor and bearing wear, seal aging, higher oil carryover and potentially airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: SSR elements differ in size and rated flow across power ranges and are not freely interchangeable. Always confirm the correct part number against the machine serial number.
