It get worse much worse simply due to the lack of due engineering diligence when designing the many aspects required for a compressor designed for human breathing applications. Take one example:
In order to extend the mechanical life Coltri made the choice to treat the piston liners with an application called nicacil. Now in the car industry and for those of us who drive a Porsche and use a Rix we don't have to worry but for those who drive a BMW and use a Coltri for example and others it's a problem.
Coltri however have a greater problem and have a responsibility to their customers who are breathing the stuff.
Although Ni–SiC coatings offer superior mechanical properties for race engines, their enhanced Ni ion release in various media such as in the oil carry over, particularly in biological environments including human breathing, and these particles contain significant environmental and human health risks.
Further it is well understood that the release of Ni ions and SiC nanoparticles into ecosystems can lead to detrimental effects in living organisms, raising concerns about their long-term environmental persistence and toxicity. There is enough research around that highlights the importance of adopting safe-by-design (SbD) principles to develop coatings that balance performance with environmental safety. By highlighting the potential ecological hazards of Ni–SiC nanocomposite coatings, All the studies done advocate the development of safer, more sustainable alternatives.
And now some poor sap is going to buy these products coated with this compound and use them for scuba diving, breathing from them and ingesting these toxins and then to tell us they bought a Coltri and have had no problems for the last 10 years. Or others who on this very forum who think ignorance is bliss in the face of repeated advice warnings and concerns for a better healthier alternative consideration.
