Entrance, M10 Protective - NSN 4240-00-229-2610

Protective Entrance (PE). A PE, when used,

provides a pressurized transition area between the

protected enclosure and the surrounding

contaminated atmosphere. It allows the shelter

pressure to be maintained during entry and exit of

the protected enclosure and while individual

decontamination procedures are being performed.

The PE operates at a lower pressure than the

main enclosure to guard against unwanted flow of

air back into the main enclosure. MCPE PEs are

collapsible for compact stowing, and are available

in both “integral” and “detachable” versions.

Integral PEs can be deployed either inside or

outside of the enclosure. Adapters allow

detachable PEs to interface with a variety of

enclosure doors.
