Swing airtight fire doors – SP250 AIR&FIRE STOP®

The SP250 AIR&FIRE STOP® airtight door has been designed to meet two different needs: to provide enhanced airtightness to protect clean and sterile rooms, and to prevent the spread of fire to protect personnel.

An airtight and fire-resistant door for operating theatres and controlled environment rooms

Consisting of a grade 304L stainless steel door frame and an impact and decontamination product-resistant compact laminate leaf, it is used in surgical suites, clean rooms, research laboratories and other controlled atmosphere rooms.

The leakage rates and fire resistance of SP250 AIR&FIRE STOP® doors have been tested and certified by different test laboratories and they have been issued with an airtightness certificate and EI30 fire resistance certificate for installation in plasterboard (Placo®) partitions and masonry walls.
