K

• Centrifugal fans designed to move gases containing dust, granular materials, and/or fibers.

This series comprises three types of impellers: KB, KR, and KF, each suitable for different applications.

KB Impeller:

• Straight blades curved backward.
• Recommended for moving air, fumes, and clean gases or those with low concentrations of suspended dust.
• It has 11 backward-facing blades welded at the front to an aerodynamic profile cone and at the back to a flat crown.

KR Impeller:

• Straight radial blades.
• Specially designed for moving air or gases containing dry granular materials, dust, or others like wood shavings and sawdust.
• It has 8 blades welded at the front to an aerodynamic profile cone and at the back to a flat crown.

KF Impeller:

• Straight radial blades without a cone (open turbine).
• Designed for transporting materials with strong adhesion, heavy, abrasive, or long fibers.
• It has 6 blades at the back, welded to a flat crown and a special barrel.
