Toolazy Quiet 4” Inline Duct Fan with Temperature Humidity Controller - Ventilation Exhaust Fan Usin…See more

Toolazy 4” Inline Duct Fan are used in indoor grow facilities and vertical farms, heating and cooling transfer, commercial drying and air filtration applications.

Our inline blowers can also create negative pressure environments, simulate wind, exhaust odors and smoke as well as intake fresh air from outdoors.

SMART PROGRAMMING: Intelligent controller with temperature and humidity programming, fan speed control, timer, and alarm system.The controller has precise temperature and humidity sensors on a 12-foot wired probe.

QUIET AND ENERGY SAVING PERFORMANCE IS VERY GOOD: The mixed flow design and the PWM controlled EC motor can be controlled using precise electronic pulses and intelligent programming.

This can make the inline fan run more quietly and reach low speed without generating noise or heat.

The energy efficiency of the EC motor is also to be twice as high, and can save up to 40% of energy costs, and can recover the cost in the long run.
