Description

APPLICATION

DESIGN

The fan casing is made of steel with polymeric coating (VENTS VKV models), aluminum (VENTS VKVA), galvanized steel (VENTS VKVz).

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.
For connection of the fans to round air ducts use the following accessories: KKV damper, GVK flexible connector, FKV counter flange.
For mounting of the fans to flat surface use the mounting frame RKV.
