The Linear Floor Plenum (LFP) are designed for a raised floor system requiring perimeter conditioning—cooling, heating or both. The LFP is suitable for light foot traffic when used in conjunction with the Linear Floor Grille (LFG) – heavy duty construction. The LFP is the most basic plenum option for the linear floor grilles, and features a side duct collar that can be used either for constant volume cooling applications or ducted to an underfloor fan box. In doing so, the fan box can provide either constant volume or variable volume cooling and heating to a cluster of floor grilles.

• Floor supported plenum, to be used with 1000 series grille border.
• Pedestal supported plenum, to be used with 125/187 series grille border for a flange-less appearance.
• Removable end-caps are supplied with each unit allowing either discrete or continuous grille appearances.
