Introducing our SPP-SD Super Duty version of the SPP panel with the new and improved EP-2 pump. This EP-2 pump is more powerful and quieter than our original EP-1 Expansion Pump. All of our SPP-SD Panels include one pump so you do not need to order an additional pump unless you have a large number of zones and dampers. The pump is designed to hang from the wall and operates whenever the fan, AC or furnace is in operation.
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.
The 24VAC electrically actuated air switches, pump, and other components that make up the SPP and SPP-SD panels actuate the Flexdampers™. All models come in a steel enclosure with a hinged door. The number of solenoids is designated by the model number.
Airzone SPP Panels use both pressure and vacuum for precise Flexdamper™ actuation. The Solenoid panels can be used with any electronic zone control panel or can be operated directly with thermostats for slave zone control. Thermostats can tie directly to the 24VAC solenoid.
