The LTG centrifugal fans in the VRK series are available in small to medium sizes. The bolted housing contains a welded impeller with back-curved blades. One side is completely open for use as an air outlet, resulting in lower dynamic pressure loss and about 25% saved power input compared to squirrel cage impellers. Fans in the VRK series are generally used at pressures of up to 8.03 ”wg, and achieve volumetric flows of up to 58 858 cfm. These fans are available with either single or double-sided intake, various drive types and a wide range of accessories.
