FansVentilators are flow-generating appliances for the conveyance of air and other gases and dust. In radial blowers the conveyed medium is drawn in axially, accelerated radially through the rotation of the impeller and expelled tangentially. The resistance to the discharged air (by ducts, pipes, filters ...) becomes overpowered by the excess pressure generated by the ventilator.
The resulting characteristics are termed resistance parabolas or system characteristics. The operating point of the ventilator is determined by the intersection point of the two curves.
We offer:
- Low-pressure fans
from 150 m³/h - 170 Pa
to 18000 m³/h - 4600 Pa
- Middle-pressure fans
from 140 m³/h - 270 Pa
to 11800 m³/h - 9000 Pa
- Fans ATEX directive 94/9/EG
Important Enquiry information: - Operating point (point of intersection, flow volume and static pressure)

- Direction of rotation - terminal box or food mounting
- Accessories
Direction of Rotation The direction of rotation is defined in relation to the suction side of the fan. The standard design is clockwise rotation. Unless otherwise specified in the order the motor is mounted at: clockwise rotation: foot R90, terminal box RO anticlock rotation: food L90, terminal box LO Other positions for the food, terminal box or condensate drain holes must defines sparately. Note: For design reasons foot mounting at R180 or L180 are not always possible! At fans with motor frame not all positions are available.
