• Throw is based on terminal velocities of 0.5 m/s - 0.25 m/s respectively.

• NC value is based on a room absorption of 10 dB, re 10-12 watts.

• Dash (-) in space indicates NC value less than 20.

6

• With G1 damper, the pressure loss is 1.136P, and add 2 for NC value.

• The performance data is tested based on A.D.C. standard.

SLL & Plenum Box Installation

• SLL linear supply air diffusers have a U-type fastening hook & an adjustable screws for installing the diffuser onto the plenum box.

• For installation, one can install the diffuser together with the plenum box.

However for some application, one can fix the box onto the ceiling, then use the U-type fastening hook to fasten the diffuser to the plenum box. Use the screw to adjust the face flush with the ceiling.
