Active Front Edge Air Curtain
The capture and containment efficiency of a CKV hood can be greatly increased by mechanically introducing streams of air to the lower front edge of the hood. The air streams create an active edge increase the hoods ability to capture and contain effluents at lower exhaust air flow. The streams of air must be made up of an extremely low volume of air while at the same time maintaining a very high velocity of travel. Hoods with an active front air edge can be as much as 40% more efficient than hoods with similar designs without an active front air edge.
Containment Panels
Containment panels are usually made of the same material as the CKV hood and are either fastened or welded to the open side of the hood. The containment panels enclose the hood and reduce amount of hood open area. The containment panels also significantly reduce the negative effects of makeup air or other air currents round the hood. Containment panels generally come in two sizes heavy duty and light duty. Hoods with heavy duty or light duty containment panels can be as much as 20% and 10% respectively more efficient than similar hoods without containment panels.
