Product Overview
The Ingersoll Rand 88111901 is a genuine replacement intake air filter element engineered 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 before it reaches the airend, protecting rotors, bearings and shaft seals from abrasive wear and extending compressor service life.
As a factory intake filtration component for the 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 for 37–45 kW class SSR machines.

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

- GB/T 14295: Air filters
- GB/T 6165: Test methods for air filter performance (efficiency and resistance)
Maintenance & 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 media is blackened, heavily loaded, 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 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 skew or twist.
- Refit the cover: Reinstall 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 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 match it precisely.
Q3: How do I know when to replace the air filter?
A: Replace when any of the following occurs: media is visibly blackened or heavily loaded; operating differential reaches the 550 Pa alarm value; or the 4,000-hour / 8–12 month interval is reached.
Q4: What happens if the air filter is too dirty?
A: A clogged filter reduces intake air, lowers discharge volume, raises specific power and energy consumption. In severe cases, dust enters the airend, wearing rotors and bearings and aging shaft seals, which can increase oil carryover and even lead to airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filters?
A: No. SSR models of different power ratings use different filter dimensions and flow capacities. Always confirm the correct part number using the machine serial number.
