EP-2 Super Duty Expansion Pump

$145.00

Introducing our new EP-2 Expansion pump with more powerful vacuum and pressure to insure you get the best performance from your Airzone SPP and SPP-SD Panels. The pump contains two internal 24VAC relays designed to operate the pump in conjunction with the HVAC blower and furnace. Two diaphragms give a redundant action for extra long life. One pump should provide adequate airflow for most applications, except where a large number and/or very large Flexdampers are used. If more damper speed is needed, order an additional pump. The pump is designed for wall mounting next to the solenoid panel and operates whenever the fan, AC or furnace is in operation. Please note: When you order our SPP or SPP-SD Panel, one pump is included.


Use Airzone SPP-SD Panels with round and rectangular Flexdampers™. Airzone™ Solenoid Panels are compatible with any conventional zone control system that supports two-position, 24vac dampers. This includes, but is not limited to most Zone Control panels made by Honeywell, Durozone, Durodyne, EWC, Aprilaire, Lennox, RCS, Ecojay, Robert Shaw, Zone Perfect and Jackson Controls.
