Drive™ CHAD® Bonsai® Velocity Pneumatic Oxygen Conserver

The BONSAI® VELOCITY pneumatic oxygen conserver includes a combination of a low- pressure regulator and an oxygen conserver. It is designed for use with a cylinder as an ambulatory oxygen system and is capable of delivering a precise amount of supplemental oxygen at the optimal point in the breathing cycle. The BONSAI® VELOCITY conserver greatly increases the efficiency in the delivery of oxygen, maximizing the beneficial effects and eliminating unnecessary oxygen waste.

When we breathe, approximately one-third of the time is spent inhaling and two-thirds Exhaling. As a result, oxygen delivered by continuous flow is wasted during exhalation. By eliminating oxygen flow during exhalation, a two-thirds savings is possible. Additionally, the oxygen available during the very first part of inhalation contributes most to meeting oxygen needs. The BONSAI® VELOCITY conserver takes advantage of these facts to provide maximum efficiency in the delivery of oxygen. This device is designed to be an integral component of a lightweight, long-lasting ambulatory oxygen system.

Cylinder Adjustment Knob: This is used to attach the unit to any CGA 870 post-valve cylinder.

Oxygen Pressure Gauge: Enables the user to monitor the contents of the compressed oxygen cylinder and is protected by a rubber guard. The BONSAI® VELOCITY conserver is equipped with a gauge that reads up to 4,000 PSI.

Selector Switch: Enables the user to select the desired setting, as well as “OFF” and “cf 2” or “cf 4” (continuous flow). When not in use, the switch should be turned to the “OFF” position.

Cylinder Alignment Pins: When assembling the unit, these parallel pins must be inserted into the holes on the CGA 870 post valve.

Seal Washer (Gasket, FR-870G): Creates the interface between the post valve and the BONSAI® VELOCITY conserver. Besides offering a rugged interface, it also surrounds the oxygen path in a ring of stainless steel or brass.
