The VRS-300 air handling unit casing consists of closed aluminum profi les connected by strong corner fasteners made of aluminum alloy or high-strength fi berglass-reinforced special plastic and three-layer panels with an internal fi ller of dense mineral wool. The panel thickness is 25 mm. For the manufacture of panel walls, a galvanized sheet with a thickness of 0.7 mm is used. On request, the exterior walls of the panels can be powder-coated, the default coating color is RAL 7004.

The panels are attached to the frame profi le by fasteners from the inside of the installation. A special seal is glued between the panels and the frame to prevent leakage through the casing. 

VRS-300 air handling unit modules are installed on 150 mm high galvanized steel support frames. It's also possible to order support frames of diff erent height - 350 mm.
