How do I size an industrial air compressor?

Size a compressor by the total CFM (cubic feet per minute) your tools and equipment require at their operating PSI, then add roughly 30% headroom for future growth and to avoid running the unit at 100% duty. Add the CFM of every tool that may run simultaneously, match the required pressure (most shop applications run 90-125 PSI), and confirm your available electrical supply (voltage and phase). A1 Compressor Warehouse offers free sizing support to match the right compressor to your application.

What is the difference between oil-free and oil-lubricated air compressors?

Oil-lubricated compressors use oil to lubricate and seal the compression element, offering long life and lower cost for general industrial use, but they require oil changes and can carry trace oil into the air. Oil-free compressors deliver Class 0 air with no oil in the airstream, which is essential for medical, dental, food, electronics, and pharmaceutical applications where any oil contamination is unacceptable. Anest Iwata oil-free scroll compressors are a common choice for these clean-air needs.

What size air compressor do I need for air tools?

Check the CFM requirement for each air tool and add the CFM of all tools that will run at once, then add about 30% headroom. Light tools like impact wrenches need 3-5 CFM, while continuous-demand tools like sanders or grinders can need 8-12 CFM or more. For most professional shops a two-stage compressor in the 5-10 HP range covers a single-bay operation; larger shops and production lines typically move to rotary screw compressors for continuous duty.

Is A1 Compressor Warehouse an authorized dealer?

Yes. A1 Compressor Warehouse is an authorized dealer for Atlas Copco, Anest Iwata, Mattei, Schulz, and EL-AV. Every product ships with genuine OEM parts and full manufacturer warranty. We serve customers nationwide with fast US shipping and provide service in the Carolinas.

What is the difference between a rotary screw and a reciprocating air compressor?

Reciprocating (piston) compressors are ideal for intermittent use and lower-duty applications, delivering high pressure at a lower upfront cost. Rotary screw compressors are built for continuous duty, running cooler and quieter with steadier air delivery, which makes them the standard for shops and plants that use air throughout the day. Variable-speed (VSD) rotary screw models further cut energy costs by matching output to demand.

Do air compressors come with a warranty and shipping?

Yes. All compressors sold by A1 Compressor Warehouse include the full manufacturer warranty and genuine OEM parts. We ship nationwide across the United States, offer same-day quotes, and provide expert sizing support to help you select the right unit before you buy.

Cycling Refrigerated Air Dryers | A1CW – A1 Compressor Warehouse

Cycling Refrigerated Dryers

A1 Compressor Warehouse stocks cycling refrigerated air dryers — the energy-saving choice for systems with variable air demand. As an authorized distributor, we supply units sized to your compressor's flow.

A cycling dryer stores cooling capacity in a thermal mass and switches its refrigeration compressor off when demand drops, instead of running continuously. On systems that don't run flat-out all day, that on-demand operation can cut dryer energy use substantially versus a non-cycling unit.

This collection covers cycling refrigerated dryers across a range of flow capacities. We'll help you match the dryer to your compressor's CFM and your demand pattern so you capture the energy savings.

Every dryer ships with genuine OEM parts and full manufacturer warranty. Talk to a specialist for sizing help, request same-day quotes, and get fast US shipping.
