Construction is simple.
A ground sheet made from anti-static reinforced Tryolla combines with 150mm skirts to create a tough, durable base unit. The one piece top tent is then attached via a zipper. Positive pressure and a constant supply of clean air is provided by a bank of fans mounted on the work cabin wall. All systems work on a horizontal laminar flow system, exhausting through user controlled vents in the work cabin entrance and back through the air lock. The design ensures that the work cabin is always positively pressurized with respect to the airlock and similarly the airlock is at a higher pressure than that of the ambient air.
