DL Pressure Switch

Thanks to its slim design and low adjusting range, the DL air pressure switch can be used for fan monitoring on condensing boiler units or on atomospheric wall-mounted units with flue gas fan.

The switch DL switches in the event of rising or falling pressure. Once the set switching point is reached, a micro switch is activated in the DL.

The switching pressure is adjusted against a spring force using an adjusting screw
