Condensate drain accessories include pans and pan treatments to manage condensate that drips from the evaporator coils of AC systems. Condensate drain pans catch runoff and direct it to a drain line. Evaporator pans collect runoff in settings where there's no access to a drain. The pans help protect floors and furnishings from water damage. Condensate pan treatments are placed in pans as part of regular maintenance to remove odors from condensate and prevent the growth of slime and sludge that can block drain lines and cause pans to overflow.
