Installation and use
Whenever possible, the air flow switches should be installed on a horizontal part of the piping or ducting.
A flexible blade, of appropriate dimensions, is activated by the air flow, determining an angular displacement of a rod that, mechanically connected to a fluctuating arm, actuates an electric SPDT switch.
Avoid therefore to place it where air currents are too strong, as well as near bends, fans or at any point where excessive turbulence may occur.
The arrow on the cover must correspond to the direction of the air flow.
