Compressors categorized as high-pressure provide air pressures between 3,200 and 5,000 psi. They’re commonly found in commercial diving, and dive shops use them as well. They tend to be bulkier and heavier than their low-pressure counterparts, but they are undoubtedly better for filling tanks.
What is the PSI of a scuba tank?
Dive tank pressures span a wide range, but the most common pressures are “low” (2400 to 2640 psi), “standard” (3000 psi), and “high” (3300 to 3500 psi).
How does a scuba tank compressor work?
Air is sucked in through an air filter into the first stage where a large piston compresses the air down to around 100-140psi. The air leaving the first stage is hot as heat is generated as a byproduct of the compression. This needs to be cooled before it enters the second stage or it would ruin the pump.
Is a scuba tank just compressed air?
Recreational scuba tanks are filled with compressed, purified air. This air contains about 20.9% oxygen. Several risks are associated with the use of pure oxygen in diving.
