The Over-Pressure Switch offers superior over-pressure draft protection for your boilers and over-draft control system.
This adjustable, differential-pressure switch monitors pressure and is typically used with the MODS™, Modulating Overdraft Damper System. If excessive pressure builds up between the boiler outlet and the system damper, the switch shuts down the heating appliance, while the EBC 31 control unit drives the damper completely open to relieve the pressure.
The switch is suitable for air, flue and exhaust gases and should be mounted in the vertical position.
