Product Overview
The 88111901 air filter element is a genuine Ingersoll Rand inlet filter designed for SSR M37, SSR M37B, SSR M45 and MM45 series screw air compressors. Using high-efficiency synthetic fiber media, it blocks dust, dirt and particulate matter from entering the airend, protecting rotors, bearings and shaft seals from wear and extending compressor service life.
Manufactured to Ingersoll Rand global technical standards, the 88111901 delivers low initial pressure drop, high dust holding capacity and straightforward installation. It is a core consumable for routine maintenance of the SSR M37–M45 range.

7. Applicable 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)
Standard 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 darkened media, heavy dust accumulation, or differential pressure reaches 650 Pa
Installation Steps
- Shut down and lock out: Switch off the main power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
- Open the filter housing cover: 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 seal 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 for media damage, pleat deformation, cracked end caps, or aged seals.
- Install the new element: Slide it onto the center stud, ensuring the seal seats correctly top and bottom without skewing or twisting.
- Refit the cover: Reinstall the cover and tighten nuts 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 part manufactured to Ingersoll Rand global technical standards, designed for SSR M37/M45 series compressors.
Q2: Which compressors does the 88111901 fit?
A: It fits Ingersoll Rand SSR M37, SSR M37B, 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 element?
A: Replace when: (1) visual inspection shows darkened media or heavy dust; (2) 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 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, causing rotor and bearing wear and seal aging, leading to higher oil carryover or even airend failure.
Q5: Can the 88111901 be interchanged with other SSR air filter elements?
A: Air filter elements differ in size and rated flow across SSR power ranges and are not freely interchangeable. Always confirm the correct part number by machine serial number.
