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

Product Overview

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

Produced to Ingersoll Rand global technical standards, the 89243778 connects precisely to the UP5 intake piping with reliable, leak-free sealing, helping protect the screw airend from dust ingress and wear.

Standards Referenced

• ISO 5011 – Inlet air cleaning equipment for internal combustion engines and compressors: performance testing
• ISO 16890 / EN 779 – Air filter classification
• GB/T 14295 – Air filters
• GB/T 6165 – Test methods for air filter performance

Maintenance and Installation

Replacement Intervals

• Filter 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 power: switch off the compressor and confirm the unit has fully stopped.
2. Remove the filter end cover: release the cover clips or nut and take off the top cover.
3. Remove the old element: pull out the used 88171913 element.
4. Clean the housing interior: wipe the inner wall and sealing face with a clean cloth to remove dust and debris.
5. Inspect the seal ring: check the seal between housing and end cover; replace if aged or deformed.
6. Fit the new element: seat the new 88171913 element in the housing center position.
7. Refit the end cover: replace the cover and secure clips or tighten the nut.
8. Full assembly replacement (if needed): if the housing is cracked or damaged, remove the intake piping bolts, take off the complete 89243778 assembly and install the new one, then reconnect the piping.
9. Start-up check: start the compressor and check all connections for air leakage.

FAQ

Q1: Is 89243778 the housing assembly or the filter element?
A: 89243778 is the housing assembly (housing, end cover and seals), not the element. The matched filter element is 88171913. For routine servicing, order 88171913 only — the complete housing does not need replacing each time.

Q2: Which compressor models does 89243778 fit?
A: It fits the Ingersoll Rand UP5-11C-8 small rotary screw compressor. If you are unsure about your model, provide the compressor serial number and we will confirm fitment.

Q3: What is the relationship between 89243778 and 88171913?
A: 89243778 is the filter housing assembly; 88171913 is the element that fits inside it. They are used together: the housing is a long-life component, the element is a consumable.

Q4: Does the housing need periodic replacement?
A: Under normal use, no. Replace the complete 89243778 only if the housing is cracked, severely deformed, the threads are stripped, or the sealing face is damaged.

Q5: How do I know when to replace the housing?
A: Replace it if: (1) the housing is cracked or broken; (2) end cover clips are broken and cannot seal; (3) inlet connection threads are damaged and leaking; (4) the sealing face is worn and cannot hold a seal.
