Twin-fan ventilation units

Helios
Fan units for continuous ventilation from Helios incorporate two fans from 125 to 500 mm diameter.
To provide continuous ventilation with standby fans, Helios offers units with two fans from 125 to 500 mm diameter in a single casing with both inlet and outlet connection. Larger sizes are available to order. TFD duct-mounted fans are designed for internal installation. Depending on mounting, access can be from above or below. When using the Helios electronic controller, stepless speed control from 20 to 100% can be achieved. The roof-mounted TFR models offer weather protection and outlet louvres, with a rear-mounted inlet spigot for circular ducting. Acoustically lined units offer lower sound levels and reduced breakout for noise-sensitive areas. Changeover panels are available to match the fans. heliosfans@aol.com
