Comech Engineering recently installed an airlock in a medical device production facility clean room.
The clean room is kept at a constant pressure of 25 pascals this meant the high speed door solution had to be air tight.
Comech engineering designed an airlock that could could retain the positive pressure while forming an airlock as an entry to the clean rooms.
The airlock consisted of two Hermetic high speed doors in stainless steel that can retain pressure up to 30 pascals.
The airlock also had to contain a fire roller shutter on the inner side as the wall was fire rated, so a framework had to stand inside the opening to carry the speed door and the fire door with everything being sealed in hermetically.
The fire door linked to the fire alarm and fitted with battery backup and controls.
A particle test was taken before and after the installation and readings were basically identical meaning the airlock was hermetically sealed and operational.
Comech Engineering supply and install Clean room speed doors in Ireland, Hermetic doors and Airlocks with Interlocked doors.
