Supply and extract ventilation systems installed in various premises. Mounting in kitchens, bathrooms and other humid premises. Ventilation air ducts requiring high pressure, powerful air flow and low noise level. Compatible with ∅ 100 up to 315 mm round air ducts.
The casing is made of low-flammable polypropylene. Ventilation unit with terminal box. Can be turned to any position. Special design of the casing permits easy dismantling of the impeller and motor block for fan servicing without dismantling the air duct.
Two-speed single-phase motor on ball bearings. Equipped with thermal overheating protection.
The control (minimum speed, maximum speed and shutdown) is executed with the integrated three-position switch (US modification) or with the external switch for multi-speed fans (specially ordered accessory).Smooth speed control is possible with a built-in speed controller (FR1 modification) or an external thyristor speed controller (available upon separate order)
Due to the compact design the fan is the ideal solution for mounting in limited spaces, including space behind a false ceiling. The fan can be installed in any section of the ventilation system from intake to the end of the ductworks. Wall or ceiling mounting with a mounting plate.TD: mounting kit for installation of one diameter fans in parallel (for boosting capacity)TL: mounting kit for installation of one diameter fans in series (for boosting pressure).
