Fritz Stephan GmbH FS240 L/min stationary or container multi molecular sieve<unk>  with buffer tanks, cylinder filling and reserve cylinders. Application: Medical facilities / Hospitals (stationary) or container solutions (e.g. Military or Disaster Scenarios) Medical<unk> s are used in hospitals or at home to concentrate<unk>  for patients. PSA generators provide a cost-efficient source of<unk> . They are a safer, less expensive, and more convenient alternative to tanks of cryogenic<unk>  or pressurised cylinders. They can be used in various industries including medical, pharmaceutical production, water treatment and glass manufacture. PSA generators are particularly useful in remote or inaccessible parts of the world or mobile medical facilities (military hospitals, disaster facilities). Portable<unk> s Fritz Stephan GmbH - Modern FS40 Lpm Compact multi molecular sieve mobile<unk>  with cylinder filling option A home<unk>  in an emphysema patient's house. The model shown is the DeVILBISS LT 4000. Since the early 2000s, many companies have produced portable<unk> s. Typically, these devices produce the equivalent of one to five liters per minute of continuous<unk>  flow and they use some version of pulse flow or "demand flow" to deliver<unk>  only when the patient is inhaling. They can also provide pulses of<unk>  either to provide higher intermittent flows or to reduce the power consumption. Research into<unk>  concentration is ongoing and modern techniques suggest that the amount of adsorbent required by medical<unk> s can be potentially "reduced by a factor of three while offering ∼10–20% higher<unk>  recovery compared to a typical commercial unit." The FAA has approved the use of portable<unk> s on commercial airlines. However, users of these devices should check in advance as to whether a particular brand or model is permitted on a particular airline. Unlike in commercial airlines, users of aircraft without cabin pressurization need<unk> s which are able to deliver enough flowrate even at high altitudes. Usually, "demand" or pulse-flow<unk> s are not used by patients while they sleep. There have been problems with the<unk> s not being able to detect when the sleeping patient is inhaling. Some larger portable<unk> s are designed to operate in a continuous-flow mode in addition to pulse-flow mode. Continuous-flow mode is considered safe for night use when coupled with a CPAP machine. Common models retail at around $600 - $3,000. Leasing arrangements may be available through various medical-supply companies and/or insurance agencies. Alternate applications Repurposed medical<unk> s or specialized industrial<unk> s can be made to operate small oxyacetylene or other fuel gas cutting, welding and lampworking torches.Philips Respironics Home<unk> .
