CK Construction Illustrations

ASLI CK jet diffusers are made out of a fixed outer frame and adjustable concentric

rings, which specially designed for high volume and long throw applications. Theconcentric rings can be adjusted 45 upward and downward or leftward andrightward depending on the installation position to control the direction of airflow.CK jet diffusers are suitable to be installed on exposed ductwork or surfacemounted in stadium, factory, theatre and etc.

Throw is based on terminal velocity of 0.25m/s Throw is based on isothermal condition

NC value is based on room absorption of 10dB, re 10-12 watts Dash (-) in space indicates NC value less than 20

The performance data is tested in zero degree deflection in axial installation (wall installation)

Example: CK-A-200mm-C1

CK Suggested SpecificationCK-A jet diffuser shall be suitable for throw of 10 meters distance with optimum acoustic properties. The outer frame and concentric rings shall be made of1.0mm thickness aluminum sheet roll formed. The concentric rings shall be adjustable with 45 deflection upward or downward without using any tools. Theconcentric rings shall be connected to the outer frame with two circular shafts in one axis. The concentric rings shall be connected to each other with twocircular shafts in an axis, which is perpendicular to the shafts connected to the outer frame. The concentric rings shall have an aerodynamic profile to diffusethe air. The outer frame shall be detachable from the concentric rings with simple tools. The diffuser shall be epoxy coated and furnished to architecturalrequirement.

Radial blade damper (C1) can be installed at the rear of CK to adjust the air flow rate. CK could be connected to a flexible duct. The opening of the C1 can beadjusted by a screwdriver from the face of the CK.

CK could be mounted on a panel and supplied as a unit. The CK panel could be installed on the wall or ceiling.
