| USE
Supply and extract ventilation systems installed in various premises with high requirements to the noise level. For ventilation air ducts requiring high pressure, powerful air flow and low noise level. Compatible with Ø 200 up to Ø 400 mm air ducts. DESIGNThe casing is made of galvanized steel, internally filled with 30 mm acoustic foam. Mixed-flow impeller made of high-quality plastic. The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high capacity, powerful pressure and low noise. External airtight terminal block on the fan casing for power supply. Mounting brackets on the fan casing for mounting to the ceiling.

MOTOR
Three-speed single-phase high-efficient motor with low energy demand on ball bearings. All motors have manual reset thermal overload protection. Motor ingress protection rating IP20. SPEED CONTROLSpeed selection with a built-in speed switch (US option) or an external multi-speed controller (specially ordered accessory). Smooth speed control is possible either with an external thyristor or transformer speed controller (specially ordered accessory) when connected to the maximum speed terminal. MOUNTINGThe unit is intended for mounting to round air ducts. The fan is installed between the air ducts. The fan casing has mounting brackets to facilitate suspended installation of the fan. While installing the fan, ensure convenient access for subsequent maintenance and repair. |
