Filters protect the compressor and the air supply. Each filter type has a job and a replacement schedule. Knowing the difference prevents both damage and overspending.
Filter Types
- Intake filter protects the air end from dust.
- Oil filter keeps the lubricant clean.
- Coalescing filters remove oil mist from the delivered air.
When to Replace
- Intake filter: per schedule or when visibly clogged.
- Oil filter: with every oil change.
- Coalescing filter: per schedule or when pressure drop rises.
Why It Matters
- Dirty filters raise energy use and reduce component life.
- Clogged coalescing filters increase oil carryover.
What happens if I skip an air filter change?
A clogged intake filter starves the air end and raises energy use, while a dirty oil filter accelerates wear.
