LFD3

Product Information

View Performance Data LFD3

The PRICE LFD3 Laminar Flow Diffuser was designed with performance and safety in mind.

This dual-chamber diffuser utilizes a carefully engineered dispersion basket along with an integrated “V” baffle to evenly distribute clean supply air across the face of the diffuser, regardless of diffuser size.

The room-side adjustable cone damper promotes distribution of supply air within the upper plenum chamber while also offering maximum convenience for balancing contractors to adjust flow rates without removing the diffuser face.

To ensure ASHRAE 170 requirements were satisfied for diffuser cleaning access, the LFD3 design facilitates quick and easy removal of all internal components without the need for tools. In addition, the design is completely free of any sheet-metal screws or other sharp fasteners that could lead to injury during the cleaning process.

The low profile one-piece plenum features fully welded corners to protect against infiltration of air from the ceiling plenum as well as loss of “expensive air” through seams in the diffuser casing.
