Overview
Dungs LGW 50 A2 Air Pressure Switch at a glance
The Dungs LGW 50 A2 is an air — and gas — differential pressure switch from the LGW programme, used to prove combustion-air pressure across the fan before the burner is allowed to light. It keeps the burner from igniting against a stalled or weak fan, a common cause of nuisance lockouts and unsafe starts. The A2 step sets the trip point in the Dungs LGW50 range, matched to the fan's proven differential. We confirm the setpoint against the burner's commissioning data so the switch agrees with the rest of the safety chain.
