|Price LFD Series Laminar Flow Diffusers
have been engineered to provide a uniform
vertical projection of supply air at controlled
low velocity. The downward projection or
“piston” motion of supply air, combined
with low-level exhaust or return air inlets
is ideal for cleanroom or operating room
applications. The laminar flow diffuser
introduces clean supply air to the space
with minimal entrainment of room air due
to its low initial face velocity.
Laminar flow diffusers located in the ceiling
immediately above the work area can
provide a controlled flow of conditioned
supply air with minimal entrainment of
residual room air. Coupled with low-level
exhaust inlets, a controlled, low velocity
mass movement of air can be maintained.
The boundary layer of the air mass is
the only place where any appreciable
entrainment of residual room air may occur.
With the boundary layer remote from the
work area, the low velocity controlled air
mass effectively isolates the work area from
any effects or contaminants of the residual
