Stainless Steel Door Cleanroom

The nobility and quality of AISI 304 and AISI 316 stainless steel, thickness 12/10, allow the use of these kind of doors where very high environmental standards are required.

The PMI door panel is the ideal solution for critical processing areas where production must be carried out with no microbialogical and particulate contamination.

The door is a monolith seamless 43 mm thick panel and the core infill can be polystyrene (DMI-P), aluminium honeycomb (DMI-H) or rockwool (DMI-R).

The doors are mounted on a 12/10 thick AISI 304 satin-finished stainless steel frame with an extruded aluminium beam with dovetail rail to join with the OC S.r.l. PMI modular partition walls.

When mounted on masonry walls a false frame is used on top of which a stainless steel cover shroud is fitted to leave clean and tidy finish.

The DMI door is also available in sliding (DMI-S) and hermetically sealed sliding options (airtight seals on four sides) (DMI-SE). The DMM door is also available in sliding (DMM-S) and hermetically sealed sliding options (DMM-SE) as above.

Door panels can be equipped with Visarm 6/7 safety glass with internal spacer in shiny stainless steel to form a flush vision panel.
