Inflatable Seal Door Set

Pneumatic seal doors provide the highest possible airtight containment in applications involving high traffic, wheeled equipment or large animals. The doorframe is flush with the floor eliminating the trip hazard inherent in mechanical seal doors. The seal around the perimeter of the door is inflated by compressed air against a wrap-around doorframe and provides excellent resistance to leakage up to pressure differences of 2000Pa (8" w.g.) and can be operated using an existing medical-grade compressed air system or if compressed air is not available, PBSC can provide a compressed air system in the pneumatic panel. PBSC provide a high quality sub-frame from the engineered interface for the door set to install into, this can be for casting into a concrete wall or a fixing to a formed opening in a stud wall. PBSC will provide the correct solution for the application. The door sets are provided with a flush maglock and proximity switch. PBSC provide a pneumatic panel with the door, this can be linked to a BMS or PBSC can provide a door control panel to operate the door. The door leaf is fabricated in a stainless steel construction with a seamless finish in the corners. The door leaf is stiffened with stainless steel bracing and is hung on the frame via solid stainless steel hinges. The steel door leaf is available with two seals on the leaf, this provides extra redundancy where required. The double seal upgrade includes extra pneumatics and pressure switches so each seal operates independently and one seal failure will not affect the other seal. The vision panels are flush glazed to the door leaf with no visible fixings. The frame has fully welded back boxes and conduits with air tight glands on the barrier interface. The services can come in from the front of the door frame or through the wall into a top of the door frame. There is an access panel on the door frame to allow service access to the pipes in the door frame. The door set is provided with a sub-frame which provides the engineered interface which the door frame seals against. The door frame seals against the wall without any reliance on the mastic seal which is used provide the aesthetic finish to the wall. The door frame is fixed via a series of studs, therefore no need for site welding and heat to the frame and wall. Another frame option is a Pharma frame which is designed with minimal visible fixings. Both frame types can have either a stainless steel or solid core HPL door leaf.
