Air Flow Switches

Mechanical Types- for detecting and proving air flow in ducts or pipes.

Electronic (calorimetric) types- for applications requiring very low flow detection or leaks or for monitoring flow in ducts, fans, and monitoring compressed air flow in small or large pipes.

Outputs can be via Relay (dry contact), or Transistor switch, and with or without flow displays.
