From a small portable inflator to a stationary single-stage compressor. Each one is tailored for a specific job.
Pancake and hot-dog air compressors make inflating tires and toys a breeze, but to power air tools, like an air brush or brad nailer, you're going to want to step-up to something more robust, like a single-stage compressor.
Inflators If you ever experienced the "low tire pressure" indicator come on while driving, then you know how much of a life-saver an inflator can be.
It makes sense to have an inflator in the trunk of each vehicle you own. It sure beats trying to find air at a gas station!
