Swinging door is used to transfer material out of the chamber without contaminating the operator. There is a swinging closing mechanism inside the chamber. A tube projects outside the chamber, protected by a tubular film and used for the removal of material. A welding strip is used as optional accessory to hermetically seal the tubular film in order to avoid contamination of the operator. The door is made as right-hand side or left-hand side depending on the side of the chamber where it will be installed. The inner part of the swinging mechanism is sealed using a static seal. The door is made using AISI316L, safety glass, POM-C FDA CRF.177.2470 and FDA CRF.177.2600 compliant silicone seal.
