Axial fan Vents VK- EC 250 (1250 m³/h)
VK fans with EC motors are the master of everything when it comes to the ventilation of indoor spaces. Whether you need an in-line fan for your grow room, office or house – this in-line fan does it all. It is made of ABS plastic, making it the lightest fan in the industry.
But don’t let its light weight fool you. VK fans with EC motors boast a high level of efficiency thanks to the EC-based motor and state-of-the-art blade design. In general, you can expect VK fans with EC motors to last more than 40,000 hours of continuous use.
High efficiency electronically commutated DC motors with backward curved blades. Such motors are the most modern energy-saving solution. The electricity consumption of EC motors is 35% lower compared to standard motors. Fans with EC motors have excellent aerodynamic properties and quiet operation. EC motors are characterized by high performance and full speed control range. High efficiency, reaching 90%, is the ultimate advantage of electronically commutated motors. The motors are equipped with ball bearings designed for a minimum of 40,000 operating hours.
The fan is controlled by an external control signal of 0-10 V. The air capacity is regulated according to the air temperature, pressure level, etc. The speed of the EC motor changes in proportion to the fluctuation of the control parameter and the fan supplies the required amount of air to the ventilation system. The maximum fan speed does not depend on the current frequency. Fans can be integrated into a single data processing control system. Specially designed software enables precise control of all fans integrated into the system.
The fans are intended for duct installation at any point of the ventilation system with the housing installed at any angle. In the case of vertical mounting, a protective outer cover must be placed on top. Fixing to the floor, wall or ceiling is done with the included mounting brackets. The electrical connection and installation must be carried out in accordance with the instructions and the wiring diagram on the terminal box.
