Dynarex Replacement RPOC-22BC 5L Concentrator Back Case, Beige, 1 EA

The Dynarex Replacement RPOC-22BC Back Case restores the rear cabinet housing for compatible Dynarex 5-liter oxygen concentrators. This molded back panel forms the structural shell that protects the internal assembly, supports airflow routing, and provides mounting points for hardware, filters, and wiring management.

Damage to the rear case — cracked plastic, broken mounting holes, or warped panels — compromises stability and can lead to vibration noise, loose internal components, and improper airflow. Replacing the housing maintains cabinet integrity and helps preserve concentrator performance, especially for rental fleets or units frequently transported between patients.

Function & role

• rear cabinet housing section for Dynarex 5L concentrators

• protects compressor, motor, and sieve beds from impact and debris

• houses rear filter openings and supports back hardware mounting

• restores structural alignment when original case is cracked or broken

Why replacement matters

• damaged housings lead to rattling, vibration, and filter misalignment

• tape/adhesive “fixes” don’t hold under heat vibration cycles

• replacing the full back case prevents progressive cracking

Installation notes

• remove top/front panels before swapping the back section

• re-use existing screws and hardware unless damaged

• ensure filter ports and wiring channels align before securing

Compatibility

• for Dynarex 5-liter oxygen concentrators using RPOC-series cabinets

• not a universal part — confirm part number before ordering

What’s included

• 1 × replacement back case — beige
  (no screws or hardware included)

The back housing is essential for maintaining cabinet stability, reducing strain on internal components, and keeping filter access points properly aligned. Replacement is standard practice in service centers and home-care maintenance when the original shell is cracked, dented, or destabilized.
