Door description:
The requirements for the GT doors are similar to the
“Technical Regulations for shelter closures”;
typical applications for gas tight and air tight steel hinged door sets are bio-hazard laboratories, pharmaceutical and industrial clean rooms, gas tight enclosures, water treatment facilities, sewage treatment works, government laboratories, fumigation suites, research facilities, hospitals, military buildings and universities;
the gas tight door is produced in double skinned steel or stainless steel of 3 mm thickness outside and 2 mm inside, filled with a non-flammable and heat insulation mineral fibre panel;
side hinged swinging type.
the door can be operated from both sides in manual operation.
