A garage air compressor runs nailers, impact wrenches, sprayers and tire inflation from one tank. Tank size sets how long a tool can run before the pump restarts, and airflow at 90 PSI (CFM) tells you how much air it delivers while it runs.
The six compressors below range from 10 gallons to 80 gallons. Tank sizes, airflow, noise and weights come from each product’s listing page and are the sellers’ own figures. We have not used these compressors ourselves. Follow the maker’s manual for setup, power supply and draining.
