The HELI VARW225/2TK Radax-VAR high-pressure duct fan is a powerful ventilation fan designed for use in various ventilation systems. With its cylindrical duct sleeve and flanges on both sides, it allows for easy installation in duct systems with a diameter of 225 mm. The fan features a robust galvanized steel housing that ensures durability and resilience. The directly driven single-phase AC capacitor motor provides maintenance-free operation and high efficiency. Thanks to dynamic balancing and low-noise ball bearings, it achieves a vibration-free operation, making it particularly quiet in use. The HELI VARW225/2TK is ideal for applications requiring a high air flow rate of up to 1800 m³/h and offers a reliable solution for air circulation in industrial and commercial environments.
