AFM Series Air Flow Monitor Dimensions: mm (inch) Air- ow monitor integrated in a protective plastic grill Wiring Example 92 x 92 / 120 x 120 (3.62 x 3.62 / 4.72 x 4.72) e.g signal device 34 (1.3) 17.5 (0.7) + 80 x 80 (3.15 x 3.15) 7.5 (0.3) The air- ow monitor provides a simple alternative to indicate positive or negative air ow of fans or blowers. 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 ow of the fan falls below 8.2 ft/s, turning the signaling device on or off. The AFM monitor can also be attached to an existing plastic grill or guard.
