| USE
Extract ventilation systems installed in various premises. Suitable for use as a component of an assembled air handling or conditioning unit. Compatible with ∅ 140 up to 500 mm round air ducts or 125x125 up to 800x800 mm rectangular air ducts. DESIGNScroll casing is made of steel and is covered with a special polymer coating. The fan is equipped with a round intake flange and exhaust rectangular flange for connection to respective air ducts. The fan casing design provides several impeller rotating positions rightwards (R) or leftwards (L) with 45° pitch angle. The casing includes mounting brackets with a mount pad for to facilitate the fan installation to an even surface. MOTORTwo-, four-, six- or eight-pole three-phase asynchronous motor with centrifugal impeller and forward curved blades. Galvanized steel impeller. Equipped with ball bearings for longer service life. Dynamically balanced impeller. IP54 ingress protection rating. SPEED CONTROLSmooth or step-up speed control with an external auto transformer or frequency inverter (both available upon separate order). |
MOUNTING
The fan is designed for installation as a single unit or as a component unit of ventilation chambers or air conditioning units. The fan has a connection possibility for two air ducts, a rectangular discharge air duct through the flange on the casing as well as a round intake air duct through the connecting flange FRZ-SV. Available upon separate order. In case of rectangular discharge air duct connection a discharge vent must be covered with the SG-SV grille to protect the fan from foreign object ingress. Available upon separate order. The vibration isolators, either of rubber type SI-G or spring-loaded type SI-F, are recommended for noise and vibration attenuation. Vibration isolators reduce dynamic loads on the fan, enhance reliability and durability of the ventilation equipment. The vibration isolators are attached through holes in the mounting pad. Available upon separate order.
