Excel Air Systems manufactures mission critical air systems for numerous markets such as technology, agriculture, emergency & disaster relief, exploration, and event services. Our products are unique, as they do not require certified mechanics for installation. We achieve this by employing skilled technicians to assemble and test each unit while providing extreme versatility by utilizing specialty refrigerant-grade resealable fittings at each connection point. These specialty fittings allow any individual to connect any size of system with ease, eliminating the need to braze, evacuate, and charge systems.
