Construction
TROX HESCO displacement flow diffusers in standard
construction are made of galvanised sheet steel. The face
plate is perforated with 3 mm holes. The visible areas are
powder coated (RAL 9010). Other RAL colours are available
on request. They are maintenance-free because they do not
use filter material. Customised versions are available. Size
tolerances ± 2.5 mm.
In the standard construction TROX HESCO displacement
flow diffusers are supplied ready to install.
The special nozzles with integral air deflector scoops are in
plastic (polypropylene) .
Round circular spigots <= 400 mm with lip seal.
