Air Quality
GAQ - Air Quality Controller & Sensor Series
Air Quality controller – wall mount, 24VAC, or 12VDC
and
Duct / Room sensor 24VAC or 12VDC
The GAQ series are Air Quality Sensors and Controllers that
automatically react to air pollution sources. 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.
