The new Biomarine BioPak 240 Revolution 4-hour rebreather has been certified by major health and safety organizations for worldwide use.

In North America the device gained certification from the National Institute for Occupational Safety and Health and the Mine Safety and Health Administration. The company said it is approved for mine and tunnel rescue, industrial accidents, hazmat cleanup, and military and homeland security operations.

Biomarine, located in Exton, Pa., is a division of Neutronics, Inc., and Gary Halpern, the chief operating officer of Neutronics, noted that the testing was extensive and rigorous. “Our next generation rebreather came up strong and lived up to its promises,” he said.

The unit’s development was based on extensive research and development, and the company called it the industry’s most advanced and easiest-to-use long-duration rebreather, delivering the industry’s lowest closed-circuit breathing resistance at all work rates.

The patented CO2 scrubber system uses solid disposable cartridges, which allow absorbent replacement in a fraction of the time required by other rebreathers, according to the company. The BioPak 240 Revolution’s quick-change cooling system features long-lasting, refreezable cooling canisters that can be changed in seconds, while the operator is still wearing the unit, the company said. The canisters are accessible externally via twist off lids, so positive pressure is maintained throughout the coolant change.

The device weighs less than any other SCBA at 33 pounds and uses a Scott AV-3000 face piece, according to the company. Dimensions are 23 inches by 17.3 inches by 7 inches.

Features of the BioPak 240 Revolution include a temperature sensor to monitor coolant installation; a pneumatic pressure gauge to display O2 status; color-coded warning signals for normal operation, low battery, possible missing coolant, and 25 percent end of service; a “bump-proof” oxygen cylinder knob to protect against accidental actuation; and a manual quick disconnect to prevent O2 loss from gauge line damage.
