The RAM AIR-PRO II is a highly efficient, intelligent indoor climate controller designed to control two exhaust/intake fans thermostatically.
Monitoring and keeping the desired air temperature and pressure, all you have to do is plug in your fans and set your desired temperature and fan speed/balance and the AIR-PRO II will do the rest.
It also features a remote thermostat sensor (accurate to +/- 1C) and twin-speed control to always ensure negative pressure for no smell leaks and optimal plant growth.
