KAFS air flow switch is a target flow switch, which can be applied in the pipeline, through the change of air volume to change the position of the blade, so that the micro switch can be opened and closed to transmit the signal of flow change, so as to control the flow.
Control and monitor air and non aggressive gases flow in ducts, chambers, etc.,of heating, cooling, and air conditioning equipment.
● Renovated SPDT micro switch ensures the reliable switch function
● Stainless steel paddle
● Cut-in and cut-out
● Brass level
● IP65

The flow switch should be mounted into a duct or chamber where the air paddle can freely point horizontally downwards. To avoid air swirl and paddle instability, straight zones should be provided for a length of 5 times the diameter of duct upstream and downstream from the installation location.
The units are factory calibrated to the minimum switch-off value. To increase the set value, adjust the range screw clockwise. Due to the risk of fracture at air speeds of higher than 5.0 m/sec, the paddle must be cut off on the marked side. When the paddle is cut off, the minimum cut-out value increases from 1.0 m/sec to 2.5 m/sec.
