Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand intake 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 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 for routine maintenance of SSR M37–M45 compressors.

Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing
- ISO 16890 / EN 779: General ventilation air filter classification
- GB/T 14295: Air filters
- GB/T 6165: Test methods for air filter performance (efficiency and resistance)
Maintenance and Installation
Replacement Intervals
- Standard conditions: every 4,000 hours or 8–12 months, whichever comes first
- High-dust conditions (mining, construction materials, woodworking shops): every 2,000–3,000 hours
- Replace immediately if the media is visibly blackened, heavily loaded, or if pressure drop reaches 650 Pa
Installation Steps
- Shut down and isolate: Switch off the main power, apply lockout/tagout (LOTO), and 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 old 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, pleats for deformation, end caps for cracks, and gasket for aging.
- 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.
Frequently Asked Questions
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 designed 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 about your model, 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) the media is visibly blackened or heavily loaded; (2) operating pressure drop 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 too dirty?
A: A clogged element restricts intake air, reducing discharge volume and increasing specific power and energy consumption. In severe cases, dust enters the airend, wearing rotors and bearings and aging shaft seals — leading to higher oil carryover or even airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: No. SSR models in different power ranges use different element sizes and flow ratings. Always confirm the correct part number using the machine serial number.
