This is a large plastic pan that goes underneath an air handler or furnace installed in an attic. Its purpose is home safety: in the event your equipment should leak water due to a malfunctioning of the drain system, the water will be caught in this pan and drained away through a drain hose (pan has female connection for drain fitting to attach to). This will keep the water from draining onto the ceiling below. Some cities require by code that this secondary drain pan be installed for all attic air conditioning, air handler or evaporator coil installations.

The AG-G30X50 (AG-4200) Goliath series, true to its name, is the strongest, most rugged HVAC secondary pan on the market. The Goliath 30"x50" secondary drain pan is designed for horizontal installation and includes the AG-4200E float switch system.  

AquaGuard float switch systems are the best way to insure the protection of your structure from the damage of condensate overflow. The AG-4200E is the complete float switch system for Goliath, Goliath Furnace, Goliath Value Series and Titan Drain Pans. The AG-4200E comes with 14 AG-GFR vibration isolators and is included with every Goliath series pan. All AquaGuard float switch systems are UL 508 listed.
