Model 6300 – Two Position Adjustment
Model 6300is fixed in either an "UP" or a "DOWN"
position through a system of clips to stationary positions.
The core is easily adjusted. An optional round opposed
blade damper is screwdriver-operated through the face of
the unit. The Model 6300has a 2-position core to guide
vertical or horizontal projection of the air.
Model 6300R – Continuous Rotary Adjustment
Model 6300Rprovides 3/4" (19) adjustability through
utilization of a threaded mechanism. The "UP" position of
the core provides vertical throw and the "DOWN" position
provides horizontal throw. The core is easily adjusted. An
optional round opposed blade damper is screwdriver-
operated through the face of the unit. The Model 6300R
has a fully adjustable core to guide vertical or horizontal
projection of the air.

from 50 to 5000 cfm (24 – 2360 l/s). They are suitable for
both cooling and heating applications. They offer the same
balanced appearance where different sizes are used in the
same zone. They feature a 360 degree air diffusion pattern
and provide excellent performance in Variable Air Volume
Systems.

Model 6300 – Two Position Adjustment
Model 6300is fixed in either an "UP" or a "DOWN"
position through a system of clips to stationary positions.
The core is easily adjusted. An optional round opposed
blade damper is screwdriver-operated through the face of
the unit. The Model 6300has a 2-position core to guide
vertical or horizontal projection of the air.
Model 6300R – Continuous Rotary Adjustment
Model 6300Rprovides 3/4" (19) adjustability through
utilization of a threaded mechanism. The "UP" position of
the core provides vertical throw and the "DOWN" position
provides horizontal throw. The core is easily adjusted. An
optional round opposed blade damper is screwdriver-
operated through the face of the unit. The Model 6300R
has a fully adjustable core to guide vertical or horizontal
projection of the air.
