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 filter housing component built for the UP5-11C-8 series small rotary screw air compressor. The assembly comprises the filter housing, end cover, sealing elements and mounting interface, and works together with filter element 88171913 to form a complete inlet filtration system.

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

Installation and Maintenance

Replacement Intervals

• Filter element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing: no scheduled replacement; replace if damaged or cracked
• Seal rings: 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 end cover: release the cover clips or nuts and take off the top cover.
3. Remove the old element: pull out the used 88171913 element.
4. Clean the housing interior: wipe the housing inner wall and sealing faces 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: place the new 88171913 element into the housing center position.
7. Refit the end cover: reinstall the cover and secure the clips or tighten the nuts.
8. Full assembly replacement (if needed): if the housing is cracked or damaged, remove the inlet piping bolts, take off the complete 89243778 assembly, fit the new assembly and reconnect the piping.
9. Start-up check: start the compressor and check for air leaks at all connections.

FAQ

Q1: Is 89243778 a housing assembly or a filter element?
A: 89243778 is the housing assembly (housing, end cover and seals), not the element. The matching element is 88171913. For routine service you only need to buy 88171913, not the whole housing.

Q2: Which 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 machine serial number and we will confirm.

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 work as a pair: the housing is a long-life part, while the element is a consumable replaced at intervals.

Q4: Does the housing need periodic replacement?
A: Under normal use the housing does not require scheduled replacement. Replace the complete 89243778 only if the housing cracks, deforms severely, the threads strip, or the sealing face is damaged.

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