About Us


The Most Trusted Brand in PPE Gear, Fire Hose Maintenance & Storage

              Since 1940 



In 1940 CT McGraw set out wanting to help protect those who protect us, so he started Circul-Air Corp. McGraw invented the Roto-Jet Hose washer, the first automatic hose washer and he also invented the original electric hose drying cabinet. Since then Circul-Air Corp has been at the forefront in manufacturing professional grade equipment that maintains the gear and equipment you trust. 73 years later with several companies coming and going Circul-Air Corp is still #1 and is still the most trusted brand in PPE Gear, Fire Hose maintenance and storage equipment. 


Our Roto-Jet Hose Washer is the most effective and efficient hose washer available. The Roto-Jet hose washer is the only washer of its kind to wash 5-inch hose and it is the fastest at 30ft of hose per minute. We have found with over 70 years experience that to properly wash your hose you need to soak it first (not just lay it out on the pavement or grass) then scrub it while rinsing away the mud, gravel, glass and other potential toxins and carcinogens. No other method is available to thoroughly deep clean your hose. Hydrocarbons can carry 98% of the toxins, including carcinogens, produced by a fire. These harmful deposits are easily and safely removed with our Roto-Jet hose washer.   


Our Dual Purpose Dryer has 100 cubic feet of interior drying space and is a true dual purpose dryer that does not require additional accessories to dry your boots, gloves, PPE Gear and Hoses. Our Dryer comes with everything you need and with a 4 hour drying time for 4-6 sets of PPE Gear and a 10-12 hour drying time for up to 500 foot of 5 inch hose, your gear and hoses will be ready when you need them. This is achieved with our dryers 900 CFM fan drawing air over 1000 watt heater strips in its professional grade high-capacity cabinet.  When emergencies arise, you want your equipment ready to go. 


Since we don’t have our Storage Raks and Dual Purpose Drying Raks manufactured overseas like some companies, we guarantee our build quality with a Lifetime Warranty on all our storage raks. Not only are our raks durable they are also built with the station ascetics in mind.   


Circul-Air is currently expanding and will be offering several new storage and washing solutions to better take care of the gear and equipment that protects you!!
