Fan Powered Box

The Underfloor Fan Powered Box (FPB) is available in various sizes and configurations to deliver plenum air to the perimeter. In cooling mode, plenum air is pulled through the fan and delivered to the perimeter to meet envelope loads. In heating mode, hot water or electric reheat coils can be used to warm the air up to meet heating demand. In interior spaces the fan powered box can be ducted to supply grilles or used to pressurize a small sub-plenum. The fan powered box will ramp up and down to meet the space cooling requirement.
