Using an advanced front double door opening device, smallwind resistance,good sealing, and high efficiency are providedA lengthened cone design helps improve exhaust power.
Galvanized steelframe:made of 275g/m² or180g/m².Providesrust protection.
Fan double doors are closed with the rubber sealing which effectivelyprevents air backflow when the fan is started at different times. Thisgreatly improves the operating efficiency by 15-20%, as comparedwith a fan of the same power.
RFAN fan blades are especially designed for top grade efficiency, beingmade of Krupp stainless steel by punch forming. It moves a large volumeof air and exhibits no deformation, breakage or dust. It is attractive anddurable. Thickness: 1.2mm; surface finish: BA grade.
