In-Pan Condensate Pump

1-ABS Series

Employing a sealed, submersible pump with sump-type pick-up, the 1-ABS offers low on and off levels and is ideal for in-pan placement for condensate removal. An integrated, unique float switch design assures reliability and security while providing easy access to the float for servicing. Designed for shallow pan tank applications such as in an existing drip tray, the 1-ABS condensate removal pump complements an air conditioner drain pan or reservoir. It can also be used for hydroponic applications such as water circulation in small trays, pans, and flood tables.
