DeVilbiss iFill Personal Oxygen ReFill Station - 535D

The Devilbiss iFill Personal Oxygen Station (item #535D) is intended for individuals and providers who already rely on portable oxygen and want consistent, on-demand cylinder refills without depending on delivery schedules. It is commonly selected when refill timing, rural access, or delivery reliability creates friction in daily oxygen routines.

The station operates with a compatible DeVilbiss concentrator, compressing concentrator-produced oxygen into refillable cylinders used for routine mobility. Cylinder selection aligns with daily activity patterns. M6 cylinders are typically used for short trips and errands, while M9, D, and E cylinders support longer outings where extended runtime is needed away from the home.

Refilling fits into normal daily use without constant oversight. Once connected, the system manages the fill cycle automatically and shuts off at the correct pressure. The closed fill design limits handling during routine refills, supporting repeat use in both homecare and clinical environments.

Built-in safety controls support consistent operation over time. The iFill includes automatic pressure shutoff, a pressure relief valve, and over-temperature protection. Adequate ventilation is required, and refillable cylinders must follow routine hydrostatic testing schedules. The station does not generate oxygen, must be used only with compatible DeVilbiss concentrators, and is not intended for liquid oxygen cylinders. It is classified as FDA Class II, manufactured under ISO 13485 standards, and supported by a three-year or 3,000-hour warranty.
