GAQ - Air Quality Controller & Sensors
24VAC wall mount, Air Quality controller
with 24VAC Duct/Room sensors
The GAQ series are Air Quality Sensors and Controllers that
automatically react to air pollution sources (PPM). They sense
tobacco smoke, toilet odors, strong kitchen smells, etc, and
mechanically regulate ventilated areas such as cinemas, pubs,
restaurants, toilets or conference rooms.
The sensor switches the fan on when air quality drops below a
preset, adjustable level. The sensing head of the unit is self-
cleaning; a process which occurs each time the unit is triggered.
When atmosphere has returned to normal, the fan switches off.
