AVTECH's Air Flow Sensors monitor air flow (or
lack of air flow) for fans and vents, such as HVAC
vents, internal/external server exhaust fans,
cooling fans, and dehumidifier fans. When air
flows through the sensor, its flap opens, changing
its switch state; when no air flow is present, its
flap remains closed (as pictured here). AVTECH
offers two types of Air Flow Sensor: one whose
switch state is normally closed (NC) and one
whose switch state is normally open (NO).

Air Flow Sensor Features
Switch States
In the "normally closed" Air Flow Sensor, no air flow = switch state closed. In the
"normally open" type, no air flow = switch state open.

Install Your Air Flow Sensor
Do not use this sensor in hazardous (classified) locations or life safety applications.
Step 1: Mount your Air Flow Sensor.
1. Position the Air Flow Sensor on the fan or vent so that any air passing through that
location will move the sensor flap.
Because the sensor's switch is magnetically actuated, iron-containing metals (like
sheet metal), electromagnetic fields (such as from transformers, motors, etc.) and
other magnets may affect the operation of the sensor. Make sure there is enough
distance between the Air Flow Sensor and those sources of interference.
2. Mount the unit in place using the clip or screw mount provided.
