The Price LFD3 Laminar Flow Diffuser was designed with performance and safety in mind. This top of the line laminar

diffuser is well suited for critical applications requiring the use of ASHRAE Group E, non-aspirating diffusers, delivering

unidirectional, non-turbulent air.

LFD3Laminar Flow Diffuser

Typical ApplicationsThe LFD3’s non-aspirating,

unidirectional, laminar flow air pattern

is ideal for applications where a low

velocity and minimal entrainment

of room air is required. Applications

requiring the use of such diffusers

include: cleanrooms, laboratories,

protective isolation rooms, and

hospital operating rooms.

LFD3 Cross Section

Product InformationThe Price LFD3 is available in multiple sizes (including metric), in both aluminum and stainless steel construction. Many standard and optional features make the LFD3 the most specifiable and robust Price laminar flow diffuser.

Dual-chamber DesignThe LFD3 dual-chamber design uses 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. Price’s highly engineered design works for a wide range of airflows, and eliminates the need to order airflow dependant models.

Quick Cleaning with Tool-free Removable BaffleFor compliance with the ASHRAE 170 requirements 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 free of sheet-metal screws and other sharp fasteners that could lead to injury during the cleaning process.

LFD3 Installation

Room-side Adjustable Cone DamperThe room-side adjustable cone damper promotes distribution of supply air within the upper plenum chamber while offering convenient adjustment of airflow rates without removal of the diffuser face.

One-Piece Welded PlenumThe low profile, one-piece plenum is just 4.75” tall. It features fully welded corners to protect against infiltration of air from the ceiling plenum as well as loss of conditioned air through seams in the diffuser casing.
