LTG centrifugal fans in the VRK series are available in small to medium sizes. The bolted housing has a welded impeller with backward curved blades.
One side is completely open for the air outlet, so the fan has a lower dynamic pressure loss and approx. 25% less drive power than drum fans. The usual pressure ranges in which the VRK series is used are up to 2,000 Pa and achieve volume flows of up to 100,000 m³/h.
This series is also available with single or double-sided suction with various drive types and an extensive range of accessories.
