Dwyer Model 530 is a highly sensitive and reliable air flow switch. It can be used with air or non-combustible, non-corrosive gases and has a rugged die cast zinc body, stainless steel vane, silicone rubber gasket, and SPDT snap switch.
The unit is easily field adjustable from 400-1600 FPM with a screw type adjustment, and has a set point adjustment that can be turned clockwise to increase the setting or counter-clockwise to decrease it. The switch must be mounted on top of a horizontal duct and requires a mounting hole and slot for the vane, as well as two 3.32” (2.38 mm) screw holes.
