USE
Supply and extract ventilation systems installed in various premises. Ideal solution for boosting large air volumes at low aerodynamic resistance in the ventilation system. Refrigerating technologies for cooling of compressor condensing units. Direct air extract. For positive pressure ventilation in firefighting systems. MOTORTwo-, four- or six-pole asynchronous motor with external rotor and axial impeller. Single-phase (E) or three-phase (D) motor modifications. Equipped with ball bearings for longer service life. Integrated overheating protection with automatic restart. |
DESIGN
Steel casing and impeller with a special polymer atmospheric resistant coating. Casing is equipped with a round mounting plate and a round flange to facilitate wall mounting. The fan is equipped with a terminal box for connection to power mains. SPEED CONTROLSmooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order). MOUNTINGWall surface mounting with a round connecting frame. Any mounting position with respect to air flow direction in the system. Power is supplied through an external terminal box. |
