Description
The Trane PAN3220 Secondary Drain Pan, is a plastic auxiliary component to collect and manage condensate overflow in HVAC systems. Mounted beneath air handlers or evaporator coils, it helps as a backup to the primary drain system by capturing excess moisture if the main drain becomes clogged or fails. This is commonly used in residential and commercial air conditioning units, particularly in installations located above ceilings or finished spaces. Its role is to prevent water leakage and protect surrounding structures by directing overflow condensate safely away from the equipment.
