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

Product Overview

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

Manufactured to Ingersoll Rand global technical standards, the 89243778 ensures precise fit with the UP5 intake piping, reliable leak-free sealing, and effective protection of the screw airend from dust wear.

• Relative humidity: ≤95% RH
• Pressure resistance: housing withstands 10 kPa negative pressure without deformation
• Serviceability: removable and cleanable for reuse; element can be changed without removing the housing

Service life and maintenance

• Housing service life: matches compressor life, generally ≥10 years under normal use
• Seal inspection: check O-rings at every element change; replace if aged or deformed
• Shelf life: 60 months in original sealed packaging, dry environment at room temperature

Standards

• ISO 5011 — inlet air cleaner performance testing
• ISO 16890 / EN 779 — air filter classification
• GB/T 14295 — air filters
• GB/T 6165 — air filter performance test methods

Maintenance and Installation

Replacement intervals

• Air filter element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing: no scheduled replacement; replace if damaged or cracked
• O-rings: inspect at every element change; replace if deformed or aged

Installation steps

1. Shut down and isolate: switch off compressor power and confirm the unit has fully stopped.
2. Remove end cover: release the cover clips or nuts and take off the top cover.
3. Extract old element: pull out the used 88171913 element.
4. Clean housing interior: wipe the inner wall and sealing face with a clean cloth to remove dust and debris.
5. Inspect O-rings: check the seal between housing and end cover; replace if aged or deformed.
6. Fit new element: place the new 88171913 element into the center of the housing.
7. Refit end cover: replace the cover and secure clips or nuts.
8. Full assembly replacement (if required): if the housing is cracked or damaged, remove the intake pipe 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 an element?
A: 89243778 is the air filter housing assembly (housing, end cover and seals), not the element. The matching element is 88171913. When replacing the element, order 88171913 only; the housing does not need to be replaced.

Q2: Which models does 89243778 fit?
A: It fits 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 into it. They are used together — the housing is a durable part (compressor life), the element is a consumable (periodic replacement).

Q4: Does the air filter housing need periodic replacement?
A: Under normal use, no scheduled replacement is required. Replacement is needed only if the housing cracks, deforms severely, threads strip, or the sealing face is damaged.

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