Best under pressure The pressure-resistant AxiEco series. The brand new AxiEco 630-910mm axial fans have air performance curves with a maximum pressure of over 2.8 in.wg. This exceeds existing axial fan designs, while at the same time lowering the overall noise level and providing impressive static peak effi ciencies of well over 50%. The axial fan range consists of three new sizes with impeller diameters of 630, 800 and 910 mm, (24, 31 and 35 inches) with a maximum airfl ow of more than 25,000 CFM of free air.
