Robertson Series 3000 Operating Louvres
are factory assembled units available in a
wide variety of materials. They are infinitely
controllable between fully open and fully closed
positions, providing the most effective form of
controlled air replacement. These louvres are
designed as single units for small openings or
multiple units for large openings. Robertson
Operating Louvres can be operated singly or in
banks.
Design Features
The wide selection of colours and materials
available enables architects to blend the louvre
with other building materials. A simple, rugged
design gives minimum static pressure drop loss
when in the open position, yet offers excellent
resistance against weather penetration. To
minimise maintenance, the louvre blades pivot on
nylon brushes.
