Intended use

The air flow switches are designed to control the air flow or non-aggresive gas flow in tubes and pipes for example in air conditioning systems or heating installations.

Function

When the air flow of the pipe pulls the Stainless Steel blade actuates a microswitch. This microswitch is inside the plastic housing and actuates according to the sensitivity adjustment.

Mechanical connection

The switch can be horizontally or vertically mounted and the indication arrow located in the process connection must be faced to the flow direction.

The device has a flange process connection and can be mounted using screws, rods, fasteners or nuts.

Dimensions

Approximate measures given in mm.
