Hello All
This is what I found out when I purchased a compressor earlier this year.
All breathing air to be used for Scuba needs to be grade "E" this is what the air at PG Dive is and has always been. It is tested quarterly at http://www.airchecklab.com.
Fire departments are allowed to use grade "D" air, which is the next level down. The next level up in purity (As far as the government is concerned) is grade "J"
This is a level that is unsustainable in a dive shop environment. It is more for laboratory use.
Any other level is based on the standards set by IANTD and ANDI. They are in effect modified grade "E". Most new compressors will pump air to this level without any additional filtration; it is just a matter of having the testing company certify the air to this standard. Which we will probably do the next time we send in an air sample.
Take a look at the Air Specifications PDF at
http://www.airchecklab.com/technotes/technotes2.html for more info.
As far as the long wait for fills. I can honestly say there have been very few instances where people have had to wait long. Some divers choose to drop tanks off on the way back from a dive and come back for them on their way out on the next; thats their choice, not a necessity.
Thank you for supporting us in our first summer of business, we look forward to diving with you.
