How to size an air compressor for your shop
Rule of thumb: 1 HP per tire changer, 1 HP per pneumatic lift, plus enough headroom for impact wrenches and shop air. A single-bay auto shop typically needs 5-7.5HP with 80 gallon tank. Busy 3-bay commercial shop needs 10HP with 120 gallon. Add 30% margin for future expansion. Not sure? Call (470) 208-2754 with your equipment list.

Air compressor FAQs
Common questions on shop air compressors.
What size compressor do I need?
Rule of thumb: 1 HP per tire changer, 1 HP per pneumatic lift, plus headroom for impact wrenches and shop air. Single-bay shop: 5-7.5HP with 80-gallon. Busy 3-bay commercial: 10HP with 120-gallon. Add 30% margin for future expansion.
Two-stage vs. single-stage?
All Atlas Air Force compressors are two-stage. Two-stage compressors produce higher PSI more efficiently than single-stage, and cast-iron construction lasts longer in continuous-duty commercial use.
Single-phase vs. 3-phase?
Single-phase 230V: standard for smaller shops without 3-phase electrical service. 3-phase 460V: more efficient for high-CFM commercial installations where 3-phase is already available. Same HP produces roughly the same air; 3-phase runs cooler and cheaper on electricity.
What's the Plus Package upgrade?
Plus Package adds an upgraded air filter, dryer, and accessory kit to the base compressor. Better air quality for spray guns and cleaner air lines. Typically $500-$950 more than the base version.
Gas-powered compressor?
Atlas AF13 is a 13HP gas-powered compressor with 30-gallon tank. Designed for portable use and job sites without electrical service. NOT for daily shop use (fuel and exhaust management).
How much electricity does an air compressor use?
5HP: ~4kW when running (~$25-$40/month typical shop use). 7.5HP: ~6kW (~$40-$60/month). 10HP: ~8kW (~$55-$85/month). Compressors cycle on/off so actual monthly cost depends on air demand.
How is delivery on air compressors?
All Atlas compressors ship LTL freight with liftgate service. Free U.S. shipping. Typical delivery 7-15 business days. Larger 120-gallon units are heavy and may require truck-with-forklift for unloading.
What warranty is included?
Standard Atlas manufacturer warranty on Air Force compressors. Typically 1-2 years on pump and motor. Pitstop Pro handles claims as authorized Atlas dealer.
Do I need special installation?
Compressor sits on shop floor with anti-vibration pads. Requires 220V single-phase or 460V 3-phase electrical service depending on model (check spec sheet). Shop air lines connect to the compressor tank output. Typical install $500-$1,500 by an electrician plus shop plumbing.
Can I finance an air compressor?
Yes. Financing options available for commercial compressor purchases through third-party lenders. See Financing page or request a personalized quote.
