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 airborne particles before they reach the screw airend, protecting rotors, bearings and shaft seals from wear and helping extend compressor service life.
As an original intake filtration component for the SSR range, the 88111901 is built to Ingersoll Rand global technical standards. It combines low initial resistance, high dust-holding capacity and straightforward installation, making it a core consumable for routine maintenance of SSR M37–M45 compressors.

Standards
- ISO 5011 — Inlet air cleaning equipment for internal combustion engines and compressors: performance testing (efficiency and dust capacity)

- GB/T 14295 — Air filters
- 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, building materials, woodworking shops): every 2,000–3,000 hours
- Replace immediately if the media turns black, shows heavy dust loading, or 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 air filter housing: release the retaining nut or clips and remove the cover.
- Remove the old element: pull out the used 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 a used element with compressed air and reuse it.
- Inspect the new element: verify part number 88111901, check the 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 skew or twist.
- Refit the cover: reinstall the cover and tighten the nut or clips evenly to achieve 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: Yes, the 88111901 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and intended for 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, provide the compressor serial number and we will confirm the correct part for your machine.
Q3: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows blackened media or heavy dust loading; (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 air filter element is left 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 major airend damage.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: Elements differ in size and rated flow across SSR power ranges and are not freely interchangeable. Always confirm the correct part number using the compressor serial number.
