The 3000 series of Air Flow Switches and Air Flow Transmitters provide the simplest, most reliable means of detecting air flow in a wide variety of industrial and commercial applications. Unlike mechanical flow switches or sail switches, the vent-captor series does not rely on moving parts.

The sensor will not be damaged by excessive air flow as often occurs with mechanical switches. It can also detect much lower flow than any mechanical device
