An air compressor powers everything from impact wrenches to spray guns and tyre inflators. Buy too small and your tools starve for air; here's how to size it correctly.
1. Air flow (CFM) is king
Every air tool lists an air-flow requirement. Add up the tools you'll run at once and pick a compressor that delivers more CFM than you need — this is the most important number.
2. Pressure (bar / PSI)
Most air tools need 6–8 bar. Compressors usually deliver up to 8 bar, which covers the majority of workshop tools.
3. Tank size
A bigger tank stores more air, so the motor cycles less and you get steadier pressure for continuous jobs like sanding or painting. Small tanks suit quick bursts (inflating, nailing).
4. Motor power (HP)
More horsepower refills the tank faster and sustains higher CFM. Match it to your busiest tool.
Bottom line: for a general workshop running impact wrenches and a spray gun, a mid-size belt-driven compressor with a 50L+ tank is a safe choice. Browse air compressors and accessories — genuine, with warranty and cash-on-delivery across Egypt.
