Greenheck Housed Plenum Array (HPA) Fan: A Modular Solution for Sound-Sensitive Applications

When it comes to HVAC systems, design engineers need solutions that balance performance, efficiency, and ease of installation. The Greenheck HPA fan checks all these boxes, offering a modular housed array designed for hassle-free assembly at job sites. Each fan ships individually on skids, allowing for easy transport and on-site assembly by just one or two people. 

One standout feature is its internal sound attenuation, with two inches of sound-absorbing material lining the interior. This reduces outlet noise by 8-10 dB compared to standard fans, making it ideal for sound-sensitive environments

Another advantage of the HPA fan is its internal isolation system. The entire fan array can be placed directly on the floor without additional isolation, and removing a fan for maintenance is straightforward—simply unbolt four fasteners. This design simplifies installation and long-term upkeep, making the Greenheck HPA fan a reliable choice for commercial HVAC projects. 

For engineers focused on creating efficient, quiet, and easy-to-maintain HVAC systems, the Greenheck HPA fan is a solution worth considering.
