Features & Benefits

Features and Benefits

Door Swing Direction

Door swing direction is easily determined while standing on the SECURE SIDE (key side) or OUTSIDE of the door.

Flush-Mount Dual Pane Windows

Flush mount dual-pane window design simplifies cleaning.

Stainless Steel Cleanroom Door

Stainless steel doors provide resistance to chemicals and minimize surface particle shedding. Choose 316L stainless steel as an optional substitute material.

Easy to Clean Flush-Mount Window

BioSafe windows forego shoddy spot-welding in favor of dual-pane glass installed flush on steel for a continuously smooth surface.

Automatic Door Bottom Gasket for Cleanroom Doors

The automatic door bottom helps maintain differential pressure inside the room. It is equipped with a fully concealed drop-down gasket that seals the bottom gap when the door closes.

Electromagnetic Door Interlock Diagram

Electromagnetic door interlock systems reduce cross-contamination by ensuring specific doors never open simultaneously. The central control module connects to electronic maglocks, allowing up to 6 interlocking doorways. Maglocks engage with 600lb of holding force and can be easily disabled in case of an emergency.
