FAQ for the Tecair System

Q.        Are the systems re-fillable?

A.         Yes, the Tecair systems are refillable with atmospheric air, using High Pressure Air compressors at 4500 psi (300 bar).


Q.        How long does it take to fill a cylinder?

A.         The fill time is based on the capacity of the compressor used, the starting pressure, and the ending pressure.  A 90L/m (3.15 CFM) compressor will fill an empty 2L cylinder to 4500 psi in under 7 minutes.  Note a user will ‘top-off’ a cylinder, there is no need to start with an empty cylinder.  A user with a low CFM or low usage tool may want to fill their cylinder before heading out at the beginning of the shift.  Most users will have sufficient capacity to make it to lunch, and be able to refill during their work break.  A user with higher air requirements could consider having two systems, leaving one unit to be pressurized while using the other. 


Q.        What is the advantage of having dry air?

A.         Pressurizing to 4500 psi results in removing almost all the moisture in the air, and in the process, the Combifilter also provides a good filtering function.  This means any tool powered by the Tecair system will work with dry, clean air.  This means the tools will last longer and perform better than when powered off of a conventional compressor.


Q.        Can I change cylinders on my Tecair system?

A.         No.  The cylinders and regulators are fixed together. 


Q.        I’m familiar with Scuba tanks, made of steel, and those are not light.  How does the Tecair system stay light when also using high pressure compressed air?

A.         The Tecair system uses Type III composite cylinders designed for low-weight and reliability.


Q.        What is the reliability of the composite cylinders?

A.         The cylinders used on the Tecair system are PI, Transport Canada and/or DOT certified with a life span of 15 years or more. While a damaged cylinder is not anticipated, should a cylinder be damaged the composite cylinder is designed to leak, not burst. 


Q.        Are these composite cylinders in common usage?

A.         Yes, the technology is commonly used to power escape slides on aircraft, for example.  It is also commonly used as breathing apparatus for first-responders, as well as for sporting applications such as paintball and for competitive target shooting.


Q.        What is the pressure at the tool?

A.         The output pressure knob sets the pressure to the tool, and can work with pressures as low as 5 psi, up to the pressure of the Tecair system used (150 psi for the K-150, 300 psi for the K-300).


Q.        I’ve also seen CO2 used to power air tools.  Is CO2 a good source for compressed air?

A.         It depends.  CO2 systems store liquid CO2.  Filling them requires a source of CO2, as opposed to HPA, which uses atmospheric air, so it could be more complicated to find the CO2.  Also, the CO2 gas comes off of the liquid CO2, meaning the cylinder needs to be stable and tilted upwards, and the performance will vary based on ambient temperature.  The Tecair system can be used in any orientation and by an active user.


Q.        If CO2 cylinder must be stable, what does that mean?  What happens when the cylinder tips over or moves quickly? 

A.         The liquid might splash around and drops of liquid CO2 would mix with the gaseous CO2.  Pneumatic tools do not react well to drops of liquid.  Air tool manufacturers know that drops of CO2 can cause tool failure.  Check your tool warrantee to see if this voids your tool warrantee.


Q.        Both types of cylinders are re-fillable, right?

A.         Yes, but…  CO2 cylinders are filled by weight, meaning their remaining capacity can only be determined by an accurate weight (knowing the tare weight).  In order to refill, they need to be emptied.  Compare that to HPA w/ the Tecair system.  It can be topped off by any HPA compressor at any time
