Mobile Containments

Share |


The HPE4500-1-T cylinder fill enclosure fills one cylinder at a time. This enclosure provides increased safety during the fill process, only operating when the door is closed and locked. The HPE4500-1-T is designed to contain the destructive force of an accidental cylinder failure or hose rupture, while allowing the air blast to be vented away from the operator.

The Class 2 Containment from HYPRES is NFPA 1901 compliant. A rupture test was performed by a third party certified licensed engineering testing facility. The rupture test followed NPFA recommended guidelines for a rupture test.


Standard Features:

  • Safety Interlock System
  • Manual ½" thick door locking bar
  • Teflon slides to protect cylinder from scuffing
  • (1) Connection for storage cylinders
  • (1) Fill hose w/SS bleed valve & fill adapter
  • (1) Panel valve to control the fill process
  • (1) Fill gauge to monitor the fill process

Construction of Fill Station:

  • Drawer contains ¼" steel plate on all four sides
  • Front of drawer contains additional ¼" steel plate
  • Outer cabinet contains ¼" steel plate on all four sides for ½" steel protection on all four sides
  • Zinc rich powder coat finish provides up to 2000 hours of protection from extreme environmental exposure


  • 90° door opening on truck mount units
  • SCUBA yoke fill adapter
  • Air management panel
  • Access Control System

Dimensions: 20.5"W x 23.5"D x 38"H (Add 4" to height for stationary containment)
Approx. Weight 400lbs.

Safety Interlock System prevents SCBA or SCUBA filling unless the front access door is completely closed and locked in place. All air control components are located inside the compartment. The carriage design "tilts" toward the operator whenever the door is opened. This facilitates loading and unloading cylinders and minimizes operator fatigue.
