The FSW800B Series air-flow monitor provides a simple but reliable alternative to indicate positive or negative air flow of fans. When properly installed and connected in series with an optical (i.e. LED) or audible signaling device, a bi-directional switch will activate an electrical contact if the air flow of the fan falls below 8.2 ft/s, thus either turning the signaling device on or off.

Does this switch operate when airflow exceeds the set value in either direction? Or is the van movement dependent on the direction of the airflow?
Thank you for your inquiry. This switch is bi-directional and will work in either direction.

What is the Flammability rating for this FSW804B?
Thank you for your inquiry about the air flow switch. Unfortunately, it is not rated for hazardous applications.
Date published: 2022-06-06
Do you have a cad model (.stp or equivalent) available for the switch to help integrate into a system?
Thank you for your inquiry! Unfortunately, we do not have and 3D models available for these switches. The only available dimensions will be those listed in the data sheet.
