The RVA mesh screen supply diffuser is intended for high
air flow ventilation systems. The diffuser is designed for
installation on square ducts, plenum (expansion) boxes and
as ductwork termination on the suspended ceiling. The mesh size
is 12.7 x 12.7 mm.
The diffusers are light-weight easy-to-install products and
require no additional bracing of suspended ceiling panels.
When installed on the PRW plenum box, they provide a
uniform air supply, while an insulated version of the plenum
box reduces the ductwork and air noise level.
