Description

Expo’s RP-Max-Z room pressurization systems are designed for type Z / Ex pz pressurisation in accordance with NFPA496 and ATEX  for Class I Div 2 and Zone 2 hazardous areas, making the interior of the room a general-purpose location.

Systems are self-contained units incorporating high flow fan units, filtration, pressure measurement and control.

Depending on the application, RP-Max-Z systems are available for single or two-door rooms, with one or two fans. Incoming air, from a non-hazardous location, is brought via ducting to the unit. Depending on local regulations or project specifications, the air inlet may be equipped with gas detection or a fire damper.
