Ingersoll Rand 89243778 Air Filter Housing Assembly | UP5-11C-8 Inlet Filter

Product Overview

The 89243778 air filter housing assembly is a genuine Ingersoll Rand inlet filtration component built for the UP5-11C-8 series of small rotary screw air compressors. The assembly comprises the filter housing, end cover, sealing ring and mounting interface, and is designed to work with air filter element 88171913 to form a complete inlet filtration system.

Manufactured to Ingersoll Rand global technical standards, the 89243778 aligns precisely with the UP5 series intake piping for a reliable, leak-free seal that protects the screw airend from dust ingress and abrasive wear.

• GB/T 6165 — air filter test methods

Maintenance and Installation

Replacement intervals

• Element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing: no scheduled replacement; replace only if damaged or cracked
• Seal ring: inspect at every element change; replace if deformed or aged

Installation steps

1. Shut down and isolate the compressor; confirm the unit has stopped completely.
2. Remove the end cover by releasing the clip or nut.
3. Extract the old element 88171913.
4. Clean the housing interior and sealing faces with a clean cloth.
5. Inspect the seal ring between housing and end cover; replace if aged or deformed.
6. Fit the new element into the housing centre position.
7. Refit the end cover and secure the clip or nut.
8. Full assembly replacement (if required): remove the intake pipe bolts, take off the complete 89243778 assembly, fit the new unit and reconnect the piping.
9. Start-up check: run the compressor and listen for air leaks at the connections.

Buyer FAQ

Q1: Is 89243778 a housing or an element?
A: 89243778 is the housing assembly (housing, end cover and seals). The matching air filter element is 88171913. For routine servicing, order 88171913 only — the housing does not need to be replaced.

Q2: Which machines does 89243778 fit?
A: It is designed for the Ingersoll Rand UP5-11C-8 small rotary screw compressor. If you are unsure, provide the compressor serial number and we will confirm.

Q3: What is the relationship between 89243778 and 88171913?
A: 89243778 is the housing assembly; 88171913 is the element that fits inside it. The housing is a long-life part; the element is a consumable replaced on schedule.

Q4: Does the housing need periodic replacement?
A: Under normal operation, no. Replace the complete 89243778 only if the housing cracks, deforms severely, the thread strips, or the sealing face is damaged.

Q5: How do I know when the housing must be replaced?
A: Replace it if: (1) the housing is cracked or broken; (2) the end-cover clip is broken and cannot seal; (3) the inlet thread is damaged and leaking; or (4) the sealing face is worn and cannot hold a seal.
