Construction

Cabinet

With high gloss surface finished manufactured from ZERO spangle galvanized steel

Kruger′s 3rd Generation Plenum Backward Curved Wheel

Specifically optimized for high efficiency in an inline configuration. Wheel manufactured in steel finished in zinc rich primer and polyester powder coating with salt spray rating up to 1000 hours (ASTM B117). All wheels are statically and dynamically balanced to G2.5 (ISO 21940).

High Precision Shaft

Belt drive shaft manufacture from C45 steel with g6 tolerance (ISO286-2), to minimize eccentricity of shaft leading to lower vibration and longer bearing life.

Safety Features

All belt-drive CFK models include a robust wire safety belt guard as standard. Optional inlet and outlet safety guards are available on request.

Built-in inlet and outlet flange for easy duct connection.

High Efficiency KRUGER Motors

Available CL-F IE3 AC motor for HIGH Temperature Application, PM motor.

Vibration Isolation

CFK cabinet internal motor installed with floor mounted spring isolators inside cabinet as standard. Optional ceiling hung or floor mounted spring isolator are available upon request for CFK cabinet external motor.
