The 1621-1389-99 is an Atlas Copco air filter element used across the ZR series of oil-free screw air compressors, with aftermarket cross-references pointing to models in the ZR110-145, ZR160, ZR250, and ZR300-ZR400 ranges. It supersedes the earlier part number 1621138900 — the two are interchangeable, so equipment nameplates or manuals referencing 1621138900 take this current part. As with any inlet filter on an oil-free screw compressor, condition matters more than on oil-injected units: because there’s no oil film in the compression chamber to trap stray particulate, a torn or poorly seated element lets abrasive dust reach the rotors directly, so a correct seal on installation is as important as the replacement itself.

How a Clogged Air Filter Actually Affects Your Compressor
Air filters don ‘t have a bypass valve — instead,as the filter media accumulates dust,airflow resistance increases gradually.This restriction forces the compressor to work harder to draw in the same volume of air,which can show up as reduced output pressure,higher energy consumption,or increased intake noise before the filter fully clogs.Some compressors have a restriction indicator or vacuum gauge on the intake line — if yours does,that reading is a more reliable trigger for replacement than a fixed calendar interval,since dust accumulation depends entirely on your operating environment, not time alone.
Environment Determines Replacement Frequency
Why Your Environment Matters More Than a Fixed Schedule
Unlike oil,which degrades on a relatively predictable time line,an air filter ‘s service life depends almost entirely on how much dust and particulate is in the air your compressor draws from.
A unit in a clean,climate-controlled plant room may run far longer than the manufacturer ‘s default interval;the same filter on a construction site or in a dusty industrial yard may need replacement several times more often.If you ‘re unsure how your environment compares to standard conditions,monitoring intake restriction (if your unit has a gauge) is more accurate than relying on hours alone.
Common Questions
How do I know when to replace the air filter if I don 't have a restriction gauge?
Without a gauge,the manufacturer ‘s recommended interval is your best default — but in dusty environments,visual inspection (checking for buildup)between scheduled changes is worth doing.
Can I clean and reuse this filter instead of replacing it?
This depends on the filter media type — some are designed for cleaning,others are not and will lose filtration effectiveness if cleaned.Check your compressor ‘s manual before attempting to clean rather than replace.
Does a dirty air filter actually reduce compressor performance?
Yes — restricted airflow forces the compressor to work harder for the same output,which can reduce efficiency and,in more severe cases,reduce achievable pressure.
Are these genuine Atlas Copco parts?
Yes.Parts are sourced through Atlas Copco distributor channels.
What is the typical lead time?
Common consumables (filters, oil) typically ship within about 1 week. Lead time for other spare parts depends on stock availability — please contact us for a confirmed schedule.
Do you inspect parts before shipment?
Yes. We provide full photos and video of the actual item before shipment, and confirm everything is correct with you prior to dispatch.
What shipping options are available?
If you have your own freight forwarder, we can ship to them directly. If not, we can provide shipping options based on your preference.
