Frequently Asked Questions:

A: It's not built for large tire inflation. For that, check out the CKMA12 or CKMTA12 compressors.

A: Yes, but with reduced duty cycle. It’s ideal for single or dual locker use with minimal air demand.

Q: Is this waterproof?
A: It’s IP55 rated — resistant to water spray and dust, but not submersible.

Q: Can it be mounted inside the vehicle?
A: Yes — it’s quiet and compact enough to mount in the cab or storage area.
