The FLX-PLO-50 plenum boxes for air valve are the lowest
plenum boxes available in FLX-REKU system.
Due to their small dimensions, these plenum boxes do not
require much installation space, which is very convenient
when they should not be prominent once concealed. This
advantage helps free up usable indoor area.
One side of the plenum box is cut off and plays the role of a
steering wheel - the air stream is immediately redirected to
the ventilation ducts. FLX-PLO-50 plenum boxes are made
of galvanized steel as a standard. Plenum boxes made from
stainless steel are available on request
