Overview 

The Aithre Twin Turbo Oxygen Maker with oxygen injection (O2i) is the World's first 4-place oxygen generator system optimized specifically for light aircraft and general aviation. With enough oxygen supply to circumnavigate the World many times, the Aithre Turbo Oxygen Maker will unlock your aircraft potential and support your mission, no matter where it takes you. And now, that mission can be higher with the introduction of the first hybrid concentrator and bottle system.  

The Turbo O2i generates oxygen using 80W of electrical power and only dips into the oxygen bottle supply when needed - at high altitudes or on user request. When the concentrated oxygen supply is sufficient for the mission, the bottled oxygen supply remains unused.

HOW IT WORKS

The Turbo O2i is a hybrid system that combines a concentrator and an oxygen bottle.  THE concentrator provides virtually unlimited oxygen at 1.1-1.4 LPM to support one person up to 18k MSL and two people up to 15k MSL, without use of the oxygen bottle.  The oxygen bottle is on standby to further increase the oxygen flow above 15k MSL, or as needed, for an additional 0.5 - 2.5 LPM.    

The bottle oxygen endurance depends largely on the altitude, bottle size, and number of users.  Included with the Turbo O2i is an ultra compact 47L oxygen bottle, which can be upgraded to a larger size if needed.  With flights below 18k for one or 15k for two, the bottled oxygen endurance is nearly infinite as the concentrator supplies all the needed oxygen using PSA oxygen concentration technology.  With the oxygen injection mode activated, the provided 47L composite bottle supplies an additional flow of 0.5 LPM - 1 LPM.

The oxygen bottle also serves as a backup supply of oxygen independent of the Turbo oxygen maker system.  A separate backup plumbing line and emergency cannula plug are included to make oxygen available even in the event of electrical failure or Turbo concentrator malfunction.

Standard with the Turbo O2i is the HealthView avionics system.  Along with output of Turbo O2i total flow rate, oxygen injection flow rate, oxygen bottle pressure, and onboard temperature, the HealthView outputs many other health and environmental parameters and allows for control of the injection component.    

The Turbo O2i kit is a complete hypoxia management system, as the system now comes standard with Illyrian II oximeters (2), Aithre Boom Cannulas (2), and the Shield carbon monoxide detector.  

CONCENTRATOR SYSTEM

The Turbo O2i concentrates oxygen real-time while you fly, anytime, anywhere, using a fraction of the capacity of most general aviation electrical alternators. Based on proven pressure swing adsorption technology (PSA), and optimized for general aviation application, the Aithre Turbo packs a punch with continuous >93% pure oxygen at 1.1-1.4 LPM using just 6 amps or 80 watts.  

A high-performance compressor pump is used to pressurize intake air and feed it through zeolite sieve beds.  The sieve beds retain the nitrogen in the air and pass oxygen through the adsorption technique (PSA).  PSA is a proven method of oxygen generation in the medical field, but the Turbo is different in that it operates above 10k MSL where the air is thinner.  

OXYGEN INJECTION SYSTEM

Any Aithre bottle may be used with the Turbo O2i; however, the 47L bottle is included with the system. Constructed from lightweight composite carbon fiber with an aluminum lining, the 47L bottle offers a 2000 PSI working pressure and includes a built-in backup adjustable flow regulator.

The Aithre 47L bottle includes a standard CGA-540 fill port, but it is one-way and doesn't require removal of any parts to fill. An elegant metal handle provides enhanced protection against impact.

There are two output ports on the regulator. The first output port is used for backup and allows for continuous flow settings of 0.5-15 LPM.  The second output port is an always-on port that connects to the Turbo O2i. 

The Aithre 47L bottle includes the standard analog pressure gauge, and also the Aithre Meso wireless pressure gauge. This provides 0-2500 PSI readings to the Healthview and to the Aithre Connect iOS app in increments of 10 PSI to permit remote pressure monitoring.   

NO BATTERY TO CHARGE

Unlike medical portable oxygen concentrators, the Turbo O2i does not use a Lithium battery.  Instead, the Turbo O2i relies exclusively on ship power 12-14V or 24-28V, using the aircraft battery or engine-driven electrical alternator.  At just 80W or approximately 6 amps at a 14V supply, the Turbo will fit within virtually any alternator capacity and this results in reduced maintenance, a longer service life, and increased flight safety.  

SMALL FOOTPRINT AND WEIGHT

With a small footprint of 22.5 cm x 14.5 cm x 15 cm and a weight of just 6.8 lbs., plus the bottle size at 6.5 cm x 33 cm overall and 3 lbs filled, the Aithre Turbo O2i will free up space and expand useful load as compared to traditional legacy bottle systems.

INSTALLED

The Aithre Turbo O2i features panel-mounted cannula plugs, remote push-button activation, hidden built-in plumbing, and the Healthview avionics system.  

A unique hook mount system is provided for removably securing the Turbo O2i to a wall, floor, or supporting member. While the Turbo O2i requires intake access to fresh air through its side ports, with center of gravity impact minimized, there are many options for mounting: tail-cone, nose-cone (for pusher or twin-engine aircraft), or the baggage compartment.

A rubber quick release mount is provided to removably secure the 47L oxygen bottle in the baggage compartment or in another accessible location.  With quick release bulkhead fittings, the 47L bottle can be easily removed for transfilling and reconnected to a remotely located Turbo O2i.

AUTOMATIC DIGITAL FLOW CONTROL OF CONCENTRATED OXYGEN

The Turbo O2i features automatic digital flow control of concentrated oxygen.  Medical concentrators often require user control of an analog flow meter to adjust and set the flow rate and the oxygen concentration.  With the Turbo O2i, the flow is set and managed automatically to help support flight safety with predictable and optimized oxygen generation.  Simply push the oxygen button and the oxygen is provided to 1.1-1.4 LPM at altitudes up to 18k MSL and >93% concentration. 

BOTTLED OXYGEN INJECTION CONTROL

Oxygen injection is default off, unless requested in the HealthView.  The request in the HealthView is made the INJ button or via settings to begin oxygen injection automatically above a set altitude for a combined concentrator - injection output.  The Healthview enables injection dosing adjustments scaled as a percentage.

ALTUS WIRELESS PRESSURE GAUGE

The Turbo O2i includes the Aithre Altus Meso wireless tank pressure gauge, which allows for monitoring the oxygen pressure remaining while the bottle is out of sight.   Readings from 0-2500 PSI are transmitted to the Healthview and the Aithre Connect iOS app to supplement the analog pressure gauge.  

ILLYRIAN OXIMETERS

The Turbo O2i system includes two Illyrian II oximeters for pilot and co-pilot.  The Illyrian wearable oximeter provides continuous real-time SPO2 and heart rate information to the HealthView and to the Aithre Connect iOS app.  Advanced features include head movement and cabin altitude monitoring with haptic vibration feedback.  

AITHRE BOOM CANNULAS

While the Turbo O2i system includes two silicone cannulas, the system additionally includes two Aithre Boom Cannulas to make oxygen delivery safer and more comfortable.  The Boom Cannula features a low profile aluminum anodized swivel adapter and an articulating boom arm, making oxygen delivery as easy and convenient as talking on the microphone.  When not in use, the Boom Arm can be pushed or swiveled up and out of the way and can be easily recharged with a new nasal arm after extended periods of use.

AITHRE SHIELD CARBON MONOXIDE DETECTOR

No oxygen system is complete without the Aithre Shield carbon monoxide detector, so the Turbo system includes the Shield carbon monoxide detector.  The Shield CO detectors offer superior 10 year no recalibration service with sensitivity below 10 ppm and responsiveness of under 60 seconds.  The Shield outputs to the HealthView avionics and to the Garmin, Dynon, and Advanced systems for additional safety monitoring.

CONCENTRATION MONITORING

The oxygen concentration produced by the Aithre Turbo O2i is >93% for 2000 hours or 2 years, whichever comes first.  There are two primary methods to verify the concentration and ensure that the Turbo O2i is operating correctly, using the Aithre Illyrian II wearable oximeter and using a portable oxygen concentration tester.  

Continuously measured blood oxygen provides a direct indication of the sufficiency of breathing oxygen during flight.  The Aithre Illyrian II is the only haptic wearable that provides a continuous readout of blood oxygen to modern avionics, the Aithre HealthView, the Aithre Connect iOS app, and via native haptic vibratory alerts.  It is the best way to monitor your blood oxygen and verify the flow, concentration, and operation of the Turbo O2i.

Additionally, a portable oxygen concentration tester can be used on the ground prior to flight to test the purity of oxygen generated using the Turbo O2i.

The portable oxygen concentration tester is not included and must be purchased separately. 

MAINTENANCE

Nothing is airborne for free, but operation of the Turbo O2i is very cost-effective as compared to FBO transfilling costs.  With the Aithre Turbo, there is a sieve bed replacement that will need to occur every 2 years or 2000 hours of usage to ensure high purity oxygen generation.  There are two options for the maintenance, including either a mail-in service or a factory refurbished exchange with zero down time.  Information on the same is accessible from our website main menu or via the separate maintenance product listings.

The oxygen bottle also requires regular filling, which can range from never to as frequently as consumed.  The carbon fiber bottle includes a 5 year hydrostatic testing requirement and an overall lifespan of 15 years.  

SAFETY

There are a number of significant safety benefits of the Turbo O2i.

Notably, the Aithre Turbo O2i does not itself store any pure oxygen so the risks associated with carrying, transporting, and filling pressurized oxygen vessels can be reduced using a smaller oxygen bottle.

Additionally, the Aithre Turbo O2i does not include any Lithium battery.  While portable oxygen concentrators designed for medical purposes rely upon a Lithium battery, this is unacceptable for aviation environments due to the combination of oxygen, heat, and battery fire risk.  The Turbo O2i relies instead on fused continuous power directly from the aircraft alternator, ship battery, and any backup ship battery available.

Other safety features include high temperature Tefzel internal wiring, three high speed cooling fans, over-temperature monitoring with auto shutdown, and capacitive electrical noise reduction.

AIRCRAFT BUILDER OPTION

If you are a builder and need some installation parts before the aircraft is flying, we do offer an option to split the kit into two sets of items with a 50% deposit.  Note though, there is NO price lock over the years and the final 50% will be based on the then-current price for the kit.  Other than the builder option, we do not split the kit up into parts and we do not offer discounts for unused or unwanted items because everything is kitted, boxed, and itemized as a single unit.

Healthview

HEALTHVIEW, AITHRE CONNECT iOS, AND AVIONICS SUPPORT

Aithre has pioneered the integration of health biometrics into the avionics of the aircraft, and the Turbo is no exception: the Turbo O2i constantly monitors total flow, onboard temperature, pressure altitude, oxygen injection flow, bottle oxygen pressure, and faults.  Data is output via serial to the Aithre HealthView and via BLE to the Aithre Connect iOS app.  For supporting avionics, a discrete output 0-12V may be connected to throw a display message in response to a fault condition.  

HEALTHVIEW I

The HealthView is the first dedicated avionics system that both controls oxygen delivery and outputs health information, including gauges for blood oxygen, heart rate, respiration rate, flow rate, cabin pressure, cabin temperature, carbon monoxide, and oxygen tank pressure.  

The HealthView features a 240 x 320 pixel TFT resistive touch LCD display with rich and vibrant graphical gauges, enclosed in an ultra-compact aluminum anodized laser etched case. The HealthView is powered by three parallel low energy processors and a wireless communication module for an exciting low heat, low power, high functionality display, using only 150mA of current at 14V. 

The HealthView works as a standalone device for cabin pressure altitude, using an internal barometric pressure sensor. But, the real power lies in the HealthView's ability to dynamically expand to feature any available Aithre device, wirelessly and with or without use of the popular Aithre Connect iOS app.  The HealthView is compatible with all Aithre devices, including the Shield series of carbon monoxide detectors, the Illyrian oximeter, the Meso oxygen pressure, the Metis wingtip temperature/dewpoint sensor, and the AVI and Turbo oxygen systems.     

Power requirements are 12-18V and only 150 mA (0.15 A). Dimensions are 90mm x 61mm x 21.5mm and weight is just under 6 ounces.  

HEALTHVIEW II WITH ATD

Available now as a variant is the HealthView II with the Air Avionics ATD-57, ATD-11, or ATD-80.  The ATD is a multi-function instrument that is low profile with high visibility graphics and tactile input controls.

The HealthView II with the Air Avionics ATD fits within standard cutouts to output all Aithre oxygen and biometric health information and provide a rich set of controls over the Avi and Turbo oxygen systems.

The HealthView II with the ATD features over 60 customizable color health fields across 9 custom pages with per station control of oxygen dosing and Turbo injection control.  All Aithre devices and their associated data will display either via BLE or the serial communication channels, including Shield, Metis, Avi, Turbo, and Illyrian products.

The ATD with the HealthView II is modular and can be optionally expanded to provide ADS-B weather and traffic.  Additional license and/or equipment is required for the weather and traffic functionality.  The companion ACD instrument is available from Air Avionics to provide communication radio, transponder, and altimeter functionality with a matching control head interface.

Power input to the HealthView II and ATD is 12-30V with a power draw of under 20mA at 12V.

HEALTHVIEW III WITH ATD

Available now as a variant is the HealthView III with the Air Avionics ATD-57, ATD-11, or ATD-80.  The Healthview III operates similarly to the Healthview II, but the difference is that the Healthview III has an integrated Shield carbon monoxide detector and wired hookups for the Metis OAT probe, Illyrian II oximeters, analog voltage outputs for the GEA24 and SV-EMS, and standard DSUB connectors.  The Healthview III also supports a panel carbon monoxide indicator light and more reliable health data through the dedicated wire connections.  

Power input to the HealthView III and ATD is 12-30V with a power draw of under 20mA at 12V.
