- Cost-effective flow switches for HVAC applications.
- High-capacity, fully-encapsulated NC/NO micro-switch.
The S6040A1003 Honeywell / FEMA air flow Switch (with separate paddle) is mounted in the vertical position (i.e. with the switch box at the top). In order to avoid air turbulence and paddle instability, the device should be installed in straight duct runs having a length of at least 5 times the duct diameter both upstream and downstream from the location of installation. The device must be mounted with the seal plate (incl. in package) through an approx. 20-mm hole in the duct. The device must be fixed with two screws (incl. in package.) The paddle must then be mounted with a screw on the shaft inside of the duct.
