VC 125 Q*

Description

APPLICATIONS
Supply and exhaust ventilation systems for various premises suitable for external surface mounting.	For premises with high requirements to noise level, we offer units in low-noise modification (VC…Q).
DESIGN
Fan casing is made of steel with polymeric coating.	Various fan modifications for surface or flush mounting are available.
MOTOR
The plastic impeller with backward curved blades is powered by means of the single-phase motor with external rotor and overheating protection with automatic restart. For some dimension types high-powered motors are available (VC…S).	Motor is equipped with ball bearings for longer service life designed for at least 40 000 hours. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly. Motor protection rating IP 44.
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
Fan is designed for surface wall mounting (VC…PN and VC…VN models) or through-the-wall mounting (VC…PK and VC...VK) depending on design modification. The fan is mounted to the wall with the mounting plate. The fan is powered through the external terminal box.	Electric connection and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
