AA-UL

The AA UL is a duct access door designed for easy install and maintenance-free re-installation of commercial exhaust duct doors. Access Armor Doors are available for high heat food processing ducts or commercial HVAC systems.

All components of the AA UL are mechanically integrated together to prevent the loss of components. Basic use is to provide an access door in commercial ductwork for the purpose of inspection and dealing with grease, dust, and potential fire hazards.

Its main panel construction is an 11 gauge, high-grade 304 stainless steel plate. The 11 gauge stainless steel panel is laser cut to exact dimensions that meet or exceed any existing requirement for access doors. 

Its two gaskets are used for grease or restaurant applications. The first gasket is a neoprene, compressed, black-out seal that compresses between the door and ductwork, creating an air-tight seal eliminating vacuum or air leak issues. The second, outer ceramic fire gasket, rated at 2300 degrees F, is for the prevention of fire transfer into the duct beyond the general path of the existing duct system.
