Is the BioPak 240R a positive-pressure, pressure-demand device?
Positive-Pressure: The BioPak 240R has been certified to provide positive breathing pressure to the user for EN145 breathing rates of 30, 50, 75 and 100 liters per minute; and, NIOSH breathing rates of 40 liters per minute. Positive pressure refers to the pressure within the breathing loop of the BioPak being higher than the atmospheric pressure outside of the breathing loop.
Pressure-Demand: Pressure demand implies that the BioPak will deliver additional oxygen into the breathing rate based upon internal pressure of the BioPak breathing loop. A better nomenclature for this term would be “volume-demand”. The BioPak will always keep a positive pressure in the breathing loop and does not actually measure the internal pressure during operation. Demand adds are provided by the BioPak when the user consumes more oxygen than what is being supplied by the constant add. This results in a lower volume in the breathing chamber that is compensated for by the diaphragm. When the volume decreases enough, the diaphragm will actuate the demand add valve to add oxygen into the breathing loop. This system is therefore totally self-regulating to the exact needs of the user.
Constant-Demand: The BioPak will deliver a stream of oxygen into the breathing loop throughout the duration of use. This flow of oxygen is intended to furnish enough oxygen to support a user at a moderate work rate such as strenuous walking. The flow is controlled by a flow restrictor within the delivery system and is not altered based upon the needs of the user. If the user oxygen consumption exceeds the rate of the constant add then the demand add will be activated. If the user oxygen consumption is lower than the constant add then resultant excess volume is vented out of the breathing loop.

Will the BioPak always provide a minimum of 4-hour duration?
FACTORS THAT CAN SHORTEN SERVICE TIME DURATION:
- High user work loads will result in high oxygen consumption rates. The BioPak supplies a finite amount of oxygen to the user. If the user uses that amount at a high rate then service time will be shortened.
- Poor faceseal of the facepiece will lead to leakage that will result in loss of oxygen at rates higher than user consumption and will lead to shortened duration.
- Poor BioPak maintenance may lead to system leaks that will result in loss of oxygen at rates higher than user consumption and will lead to shortened duration.
- Excessive use of the emergency bypass valve will consume oxygen at very high rates that will result in loss of oxygen at rates higher than user consumption and will lead to shortened duration.
- User physical condition will dictate the rate of oxygen consumption. Users that are not in peak physical condition will most likely consume oxygen at greater rates than users that are in peak physical condition.
What is the nominal duration of the coolant canisters?
What is the average temperature of inhaled air?
What is the oxygen concentration of inhaled air?
What is the breathing resistance of the BioPak during use?
Can the BioPak be worn within a Level A suit?
In what applications can the BioPak be utilized?
Can the BioPak be utilized for diving applications?
- The use of an oxygen enriched respirator in environments of greater than 1-atmosphere pressure will result in oxygen toxicity that could lead to user death.
- The BioPak is not designed to be neutrally buoyant and is actually positively buoyant. Therefore it would very difficult to keep the BioPak submerged without constantly floating on the surface of the water.
- The facepiece utilized with the BioPak is of a curved lens design that will provide a distorted view underwater.
Can the BioPak be used for 1 or 2 hours then taken off the user and reused at a later time without changing the CO2 scrubbers?
- The oxygen cylinder is closed and the storage plug has been installed into the facepiece adapter.
- The BioPak is totally sealed with the breathing chamber lid fully closed and the breathing chamber lid can not have been opened after use.
- That the BioPak is reused within a period not exceeding 24-hours by the SAME user.
- That the oxygen cylinder has not been refilled or topped off to provide additional oxygen.
These restrictions are put in place to prevent loss of oxygen stores, conserve carbon dioxide scrubber capacity, prevent the internal growth of mold and bacteria and to prevent the transmission of any user-borne viruses or germs.

Are there protective options for the rubber breathing hoses?
- Anti-Crush Rings: These are injection-molded rings from a stainless steel/polycarbonate alloy that will slide over the breathing hoses and lodge into position between the hose convolutions. The presence of the rings will prevent hose collapse from pinching and will allow the user to carry equipment or other objects on their shoulders on top of the breathing hose.
- Kevlar® Hose Covers: These covers are fitted over the hoses and closed with a zipper. The Kevlar® mesh of the covers will provide a measure of protection against hose abrasion.
- Heat Reflective Cover: This cover is a single cover that covers both hoses and the facepiece adapter. The cover is closed with a zipper and is constructed of fire-resistant and heat reflective materials to provide additional protection from high radiant heat.
