The casing of the air handling unit of the VRS-700 series consists of closed aluminum profi les connected to each other by strong corner fasteners made of aluminum alloy, three-layer panels with an internal fi ller made of dense mineral wool. The panel thickness is 50 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 with self-tapping screws from the inside of the installation. A special seal is glued between the panels and the frame to prevent leakage through the casing.

VRS-700 air handling unit modules are installed on 200 mm high galvanized steel support frames.
