AC Infinity Cloudline T4 Quiet 4 in. Inline Duct Fan Temperature Humidity Controller Hydroponics Ventilation Heating Cooling Booster

The new Cloudline series contains a cutting-edge electronically commutated (EC) motor, controlled using precise electronic pulses and smart programming. This enables the inline fan to operate considerably quieter and reach low speeds without generating noise or heat. The EC motor is also twice as energy-efficient and can save up to 40% in energy costs, paying for itself in the long run.
