Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand inlet filter engineered for SSR M37, SSR M37 B, SSR M45 and MM45 series screw air compressors. Its high-efficiency synthetic fiber media blocks dust and particulate matter from entering the airend, protecting rotors, bearings and shaft seals from abrasion and extending compressor service life.
As a factory inlet 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): every 2,000–3,000 hours
- Replace immediately if visual inspection shows darkening, heavy dust loading, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and isolate: Turn off main power, apply lockout/tagout (LOTO), confirm the unit has fully stopped.
- Open the filter housing: Loosen 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 walls and sealing surface 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 skewing or twisting.
- Refit the cover: Reinstall the cover and tighten the nut or clips evenly to ensure 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 the 88111901 a genuine Ingersoll Rand part?
A: Yes, the 88111901 is a genuine Ingersoll Rand replacement part manufactured to Ingersoll Rand global technical standards 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 machine serial number and we will confirm the correct part.
Q3: How do I know when to replace the air filter element?
A: Replace when: (1) visual inspection shows darkening or heavy dust; (2) operating differential 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 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, wearing rotors and bearings and aging seals, which can increase oil carryover or even lead to airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filters?
A: SSR models of different power ratings use different element dimensions and flow capacities, so they are not freely interchangeable. Always confirm the correct part number using the machine serial number.
