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

Product Overview

89243778 is a genuine Ingersoll Rand air filter housing assembly — the intake filtration 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 is designed to work with air filter element 88171913 to form a complete intake filtration system.

Manufactured to Ingersoll Rand global technical standards, the 89243778 housing aligns precisely with the UP5 series intake ducting, delivers reliable leak-free sealing, and protects the screw airend from dust ingress and wear. As a non-consumable component, the housing is normally replaced only when damaged.

Maintenance & Installation

Replacement intervals

• Air filter element 88171913: every 2,000–4,000 hours or 6–12 months
• Housing 89243778: no scheduled replacement; replace only if cracked or damaged
• Seals: inspect at every element change; replace if deformed or aged

Element change steps

1. Shut down and isolate power; confirm the compressor has fully stopped.
2. Release the end cover clips or nuts and remove the cover.
3. Withdraw the used 88171913 element.
4. Wipe the housing interior and sealing faces clean of dust and debris.
5. Inspect the seal between housing and end cover; replace if aged or deformed.
6. Fit the new 88171913 element into the housing centre.
7. Refit the end cover and secure clips or nuts.
8. If the housing itself is cracked or damaged, remove the intake duct bolts, replace the complete 89243778 assembly, and reconnect the ducting.
9. Restart the compressor and check all connections for air leaks.

FAQ

Q1: Is 89243778 a housing assembly or a filter element?
A: 89243778 is the housing assembly (housing, end cover and seals). The matching filter element is 88171913. For routine servicing, order 88171913 only.

Q2: Which compressor models 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: How do 89243778 and 88171913 relate?
A: 89243778 is the housing assembly; 88171913 is the element that fits inside it. The housing is a long-life component; the element is a consumable.

Q4: Does the housing need periodic replacement?
A: No. Under normal use it does not require scheduled replacement. Replace the complete 89243778 assembly only if the housing is cracked, badly deformed, the threads are stripped, or the sealing face is damaged.
