Bonsai® Velocity Pneumatic Oxygen Conserver

can be used as cf or pulse rate with just a turn

If it were not for the 4 liter flow I would not be able to leave the house.... the 6 pulse keeps me comfortable while sitting the 4 continuous gets me there while walking short distance

I have tried several other Conserving Regulators including battery powered units. This unit is very quiet on 1-2 LPM, my usual settings. The sound at 3 becomes more noticeable. Very pleased, would buy another for a spare. Have not tried it in cold weather yet.

I love this unit. It is the quietest pneumatic type oxygen regulator on lower doses I have been able to find, and no batteries to change. I have found that in my case, using 4 ft. flared tip (because of large nostrils) cannulas, the unit senses my inhalation right at the start. On my unit, the puffs on the 1and 2 L settings are almost inaudible, not a louder puff like other makes I have tried or own. I have not had it long enough to try it in cold weather yet. Only improvement I would like, would be an easier turning selector with more positive detents.

I don't have to swap conservers when I use my large tank, now I have it on there all the time. I like not wasting the oxygen on the old regulator that was always on.
