| USE
Supply and extract ventilation systems installed in various premises. Mounting in ventilation systems with low static pressure requiring high air capacity. Direct air extract. MOTORSingle-phase asynchronous motor with an internal rotor and an axial impeller. Motor with slide bearings. Integrated overheating protection with automatic restart. SPEED CONTROLSmooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order). |
DESIGN
Compact steel casing covered with special polymer coating. Aluminium impeller. The casing is equipped with a round mounting plate and flange for easy surface wall mounting. The fan is equipped with a power cord and external terminal box for connection to power mains. MOUNTINGWall surface mounting with a round connecting frame. Horizontal installation with respect to air flow direction in the system. Power supply through an external terminal box with electric lead-in. |
