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

Seattle, WA —August 22, 2024

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.
