Model ECV-40 is the latest addition to Greenheck’s energy core ventilator line. The ECV-40’s new design features a dual-fan arrangement consisting of direct drive mixed-flow plenum fans with variable frequency drives replacing the forward-curved fan typically found in energy core ventilators.
The mixed-flow fan, a hybrid between an axial propeller and centrifugal fan, reduces brake horsepower requirements by up to 50%. The VFDs facilitate ease of balancing at start up. Sound power levels are reduced and no belts make maintenance easy. The ECV-40 is available with AHRI-Certified fiber or polymer membrane cores with an airflow capacity up to 5,000 cfm.
