HV-VMA middle pressure axial-flow fan series

Middle pressure axial-flow fan with aluminum impeller and direct drive.

VMA nominal sizes: 560-1000mm.

For extraction or supply of pure air with max. temperature of 50°C or 80°C. Also for horizontal and vertical  mounting positions!

Description:

Casing of sheet-steel with rolled flanges on both sides and with bolted motor support. Surfaces protected through hot dip galvanizing or powder-painting.

Impeller with airfoil aluminum cast alloy blades and aluminum cast alloy hub and with a taperlock hub connection on motor shaft. Pitch angle is infinitely adjustable at rest. Impeller is dynamically balanced according to EN ISO 1940-1, balance quality class G6.3.

Three-phase alternating current motor /IEC – standard motor in B3 mounting form, protection type IP 55/ insulation class ISO-H. Motor power selected for a cold start at pure air with a density of ρ =1,2kg/m³. Electrical wiring on the externally located terminal box.

Performance curves are according to EN24163 and EN ISO 5801 tested in a tube testing station.
