Inline centrifugal fan VENTS VKMz 315 | official VENTS website

Description

APPLICATIONS
Supply and exhaust ventilation systems for commercial, office and other public or industrial premises.	For premises with high requirements to noise level we offer units in low-noise modification (VKMz…Q).
DESIGN
The fan casing is made of galvanized steel.
MOTOR
The impeller with backward curved blades is powered by the single phase motor with external rotor and overheating protection with automatic restart. Some standard sizes are available with high-powered motors (VKMS). The motor is equipped with ball bearings for long service life designed for at least 40000 hours.	For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly. Motor protection rating is IP44.
SPEED CONTROL
Smooth or step speed control with a thyristor or autotransformer speed controller.	Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.
MOUNTING
Mounting at any angle to wall or ceiling is performed with fastening brackets supplied with the unit. The fan is powered by means of the external terminal box.	Electric connection and mounting shall be performed in compliance with the manual and wiring diagram on the terminal box.
