Housed plenum array
The Housed Plenum Array Model HPA by Greenheck is designed for fan array installations in air handler applications. The Model HPA features a direct-drive galvanized plenum fan mounted inside a sound-attenuating housing. Integrated isolators between the fan and housing reduce vibration, eliminating the need for isolators and gaskets between modules. Available in 10 wheel sizes and three different housing options, the Model HPA is ideal for replacement or air handler applications as its small, lightweight design makes it easy to move, stack, and install. The Model HPA is licensed to bear the AMCA seal for sound and air performance.
