Replacing this HVAC collector box seal during a secondary heat exchanger inspection prevents common furnace pressure switch errors and maintains the factory-spec static pressure required for optimal combustion
the Spiralink design uses a single flexible member to provide the same torque transfer with superior resistance to fatigue and misalignment
Connect the higher pressure source to the "High" inlet (P1) and the lower pressure source to the "Low" inlet (P2)
Whether you are performing a seasonal overhaul or an emergency service call
it can be programmed to respond to occupancy status shared over the network or via a hardwired dry contact connected to a universal input
