Air Flow Switch
The air flow switch provides a signal to the monitoring system
when there is not enough air pressure from the blower. If a

requiring, as a minimum standard for main gas
shut-off systems, the use of an air pressure switch
in conjunction with other system components.

blower options are available through Eclipse Combustion. Price
