SDGroup Has Revolutionalized the Portable Oxygen Concentrator

The result is a light weight, aesthetically appealing, easy-to-use personal oxygen appliance with the most sought-after consumer features of any Portable Oxygen Concentrator available today, including:

Ergonomic Design
User Friendly Operation
Factory-Free Maintenance
Five Pounds Weight
Five Hours Duration
Low Cost

Patented technology synergized with ergonomic design and world class components results in a POC that leaves the competition breathless.


Design Revolution- Ergonomic design lets you move comfortably across the room or around the world.

Elegant Convenience
Can be carried or worn comfortably and discreetly.

Light Weight
Weighs approximately 5 lbs.

Quiet Operation
45 decibels - quieter than the average conversation.

Compact Size
9.5" x 3.5" x 9.5"

High Output
750 ml Oxygen per minute continuous flow (3 l/min equivalent)

Usability Revolution- Engineered for easy operation and simple maintenance.

No-Fuss Filter Change
User-replaceable filter module means ZERO returns due to moisture degradation.

Slide-In Battery Change
Easy access, easy -swap battery.

Choice of Power Source
120 volt AC household, 12 volt DC automotive or onboard battery pack.

Extended Battery Options
Choice of three energy level rechargeable battery packs for differing activities.

Conserver
Controllable pulse profile

Materials Revolution- Our proprietary molecular sieve bed, enabled by exclusive
ultra rapid-cycle adsorbents, allows reduced appliance size.

Adsorbents
SDGroup scientists have partnered with the premier supplier of molecular sieve for POCs to develop an adsorbent that performs in the ultra-rapid cycle regime. The result is an adsorbent enabeling the reduced size and mass of the entire appliance, making all other POCs obsolete. User-replaceable filter module means ZERO returns due to moisture degradation

Adsorbent Kinetics
SDGroup's new generation sieve material (top graph) increases cycle rate 10x compared with performance of sieve used in the leading POC currently available (bottom graph), thus reducing
adsorbent invetory by a factor of ten.

Components Revolution- We have combined our exclusive sieve bed with energy efficient components to produce the new world standard for POC systems.

Electronics
Integrated power management firmware efficiently controls sensors, valves, compressor and conserver.

Efficient electronics extend battery life

Batteries
Three different energy level battery packs slip in to provide a choice of weight and duration that match patient needs
