Aluminium frame with panels made of acrylic glass. Base panel, integrated connector for exhaust system and closing lid made of PE. Iris-port openings and cable lead-ins made of PE and silicone. 2 lead-ins for cable on the back side(upper left and upper right). 2 crosswise slotted silicone discs each in the openings and cable lead-ins. They are staggered mounted so that the overlapping segments at the same time allow easy access to the interior space and close the openings at non-use. The Iris-port openings ensure pressure compensation through air streaming when the exhaust system is switched on. Connection to exhaust system through an integrated connector on the top panel. This connector is graded for tubes with inner Ø 100, 120, 160 and 180 mm. When working without exhaust system the opening can be closed with a lid.

Applications:
Direct connection to an existing exhaust system through the integrated connector. Easy access to the interior space through Iris-port openings, no complex change of gloves.
