Centrifugal roof fans with horizontal air exhaust
APPLICATION
- Exhaust ventilation system for various premises suitable for roof mounting.
- Compatible with Ø 200-630 mm air ducts.
- Suitable for any roof types as well as vertical ventilation shafts.
DESIGN
- The fan casing is made of steel with polymeric coating (VENTS VKH models), aluminum (VENTS VKHA), galvanized steel (VENTS VKHz).
MOTOR
- 2-, 4- or 6-pole single- or three-phase asynchronous motors with an external rotor and impeller with backward curved blades.
- The motor is equipped with thermal overheating protection with automatic restart as well as ball bearings for long service life.
- For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
- Motors protection rating IP44, IP54.
SPEED CONTROL
- Both smooth or step speed control is performed by means of the thyristor or autotransformer controller.
- Several fans can be connected to one controller in case the total power and operating current do not exceed the rated controller values.
MOUNTING
- The fan is mounted on the roof directly above the ventilating duct or shaft and is firmly fixed to the flat surface by means of a connecting plate.
- Electrical connection and installation shall beperformed in compliance with the manual and circuit diagram on the terminal box.
