The Model 2001B-STD-CII is a Pepperl+Fuchs Bebco EPS Type X purge/pressurization system (from their older 2000 series), designed for Class II hazardous locations. It reduces the classification inside a protected enclosure from Division 1 to non-hazardous, allowing general-purpose equipment inside. It's rated for maximum enclosure volumes up to 50 cubic feet (in Class II applications).

Specific weight details for this exact model aren't widely published in current online specs (as Pepperl+Fuchs has shifted to newer series like 6000), and datasheets/manuals for the legacy 2000 series don't explicitly list a unit or shipping weight for the 2001B in the accessible sources. Similar Bebco EPS purge/pressurization control units from related models (e.g., in the 1000 or other series) often have shipping weights in the range of 5–15 lbs for smaller units or up to around 45–47 lbs for larger or more feature-rich panel-mounted systems.
