This type is characterised by high indication, which suits in rapid
decay of supply air velocity and temperature
The recommended supply air temperature differential
range is 10K. while the recommended ceiling height is between 2.6
The perforated face has 7.5mm diameter holes
on 6.25mm center in a 60 degree staggered pattern.
