Replacement molecular sieve bed to fit DJMed Battery Portable Oxygen Concentrator

A molecular sieve bed is a crucial component of a Portable Oxygen Concentrator (POC). A POC is a medical device used to provide supplemental oxygen to individuals with respiratory conditions or low oxygen levels in their blood. It takes in ambient air, which contains about 21% oxygen, and concentrates it to deliver higher levels of oxygen to the user.

The molecular sieve bed is a specialized material that plays a vital role in the oxygen concentration process. It is typically made of zeolite, which is a porous substance with a high affinity for certain gases, particularly nitrogen. The zeolite used in the molecular sieve bed has the ability to preferentially adsorb nitrogen molecules while allowing oxygen molecules to pass through more easily.

Here’s how the molecular sieve bed works in a Portable Oxygen Concentrator:

  • Air intake: The POC draws in ambient air from the surroundings using a compressor or another mechanism.
  • Filtration: The air goes through a series of filters to remove dust, pollutants, and other impurities.
  • Compression: The filtered air is compressed to increase its pressure.
  • Sieve bed adsorption: The compressed air is then directed into the molecular sieve bed, which contains the zeolite material. The zeolite attracts and adsorbs the nitrogen molecules, effectively separating them from the oxygen molecules.
  • Oxygen enrichment: The purified oxygen, which now has a higher concentration due to the removal of nitrogen, is collected and delivered to the user through a nasal cannula or mask.
  • Release of nitrogen: After some time, the molecular sieve bed becomes saturated with nitrogen. To regenerate the bed and release the adsorbed nitrogen, the POC adjusts its operation, either by venting the nitrogen or using a separate outlet to release it into the atmosphere.
    This cyclic process of adsorption and release continues to provide a constant supply of concentrated oxygen for the user. The molecular sieve bed is a critical part of the POC’s functioning, enabling it to be lightweight, portable, and suitable for use in various settings, including home care and travel.

The Solax, E-Traveller, Sweetrich, Quingo Range all come from our WA warehouse and will take an addition 2-4 business days. 

MEDICAL & ESSENTIAL MACHINES: 

Specialty machines such as oxygen concentrators, patient monitors, Mobility scooters & mobility aids, suction machines etc. (Ask for other machines) are not dispatched same day as they require 1 business day for QC and testing before dispatch.
