Mastering Sieve Bed Refilling: The Snow Fall Method for Optimal Performance
The performance of an oxygen concentrator is directly tied to the integrity of its sieve beds. The method of refilling is as important as the material itself. This article introduces the “snow fall method,” a best-practice technique for refilling sieve beds that ensures even density and prevents air channeling, maximizing the efficiency of the PSA process.
A Technician’s Guide: Disassembling and Cleaning a DeVilbiss Rotary Valve
The rotary valve is a critical component in many DeVilbiss oxygen concentrators, directing the flow of air through the PSA system. A dirty or malfunctioning valve can lead to purity issues, pressure alarms, and overall system failure. This guide offers a step-by-step process for biomedical technicians to correctly disassemble, clean, and reassemble a DeVilbiss rotary valve (part number 515A-702).
