LINEAR SLOT DIFFUSERS
• Flush - mounted linear diffuser.
• Available in 1 to 6 slots.
• Lengths are available on request.
• 180° fully adjustable air flow pattern by mean
of two air deflector per slot.
• Available with hit-and-miss damper which
controls the air flow rate without affecting the
air flow pattern and works as an equalizing
grid.
• For each slot the air deflector and hit-and-miss
damper are individually adjustable.
• Removable straight type end cap allows
extending or shortening slot diffuser line
without replacing existing pieces.
• The deflector and the hit and miss damper are
powder coated with black color as standard.
• Linear slot diffuser is powder coated to RAL
codes. Also can be in anodized finish.
