Ideal for monitoring and controlling air flow in HVAC systems, air ducts, air handling units, ventilation systems, and industrial air management applications. Suitable for air and non-aggressive gases in heating, cooling, and air conditioning equipment.
Mount the flow switch in a duct or chamber where the air paddle can freely point horizontally downwards. Provide straight zones of 5 times the duct diameter upstream and downstream from the installation location to prevent air swirl and paddle instability.
Units are factory calibrated to minimum switch-off values. Adjust the range screw clockwise to increase set values. For air speeds exceeding 5.0 m/sec, the paddle must be cut off on the marked side, which increases the minimum cut-out value from 1.0 m/sec to 2.5 m/sec.
