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 (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.
