CBDC fills cylinders for the recreational diver, commercial diver and fire firefighter.  We fill low pressure and high pressure SCUBA cylinders (up to 3500 psi) of any size including large surface supplied air cylinders for commercial diving operations and SCBA cylinders for our fire fighters. 

CBDC air quality is closely monitored for contaminates including carbon dioxide, carbon monoxide,  hydrocarbons and moisture.  Air samples are analyzed on a quarterly basis by an independent laboratory that specializes in air quality analysis.  The results of this analysis show that our air filtering system is providing SCUBA air quality that exceeds standard SCUBA air and is compatible with high-pressure oxygen environments.  The analysis is posted in the shop for your inspection.

Our high air quality means that CBDC fills all cylinders with Modified Grade E "Oxygen Compatible" air, which is a real bonus for the NITROX diver who must keep his/her cylinders oxygen clean and oxygen service rated.

Are you in town visiting or don't yet own your own cylinders?  CBDC rents air and NITROX cylinders plus we have a great line of quality aluminum and steel cylinders for when you decide it's time to buy.
