The VENTS VK-U fans offer high performance ventilation in medium to high demand systems. The fans feature built-in temperature and speed control and are suitable for a wide range of residential and commercial applications and are perfect ventilation solutions for the Hydroponics market. The fans are fitted with backward curved centrifugal impeller driven by powerful sealed external rotor motor with lifelong bearings and thermal protection. This powerful combination enables the VENTS VK-U fans to deliver exceptional airflow performances even in high static pressure systems.

The fans’ casing is made of high quality UV-resistant plastic (UL94 certified plastic). The VENTS VK-U fans are specially designed for simple installation and years of maintenance free operation. VENTS VK-U Series fans feature built-in temperature and speed controller, which start and stop the fan according to the set speed at the desired temperature. VENTS-VK Series fans are an ideal solution for intake and exhaust ventilation of premises where air temperature control is required such as in greenhouses. Simply set your desired operating temperature with one knob, your minimum speed with the other knob and let the fan do the rest.

Temp and Speed Control Function:

When the temperature exceeds the previously set temperature, the speed controller starts the fan on the set speed. As the air temperature drops below the set temperature, the control switches the fan off. As soon as the air temperature rises again and the temperature sensor exceeds the previously set temperature, the motor automatically switches to the set speed. As a result, the fans only run when needed. Temperature settings range from 70 °F to 95 °F.
