We fill all breathing air at 200 psi per min max fill rate and Oxygen at 50 psi per min. We will not over fill a cylinder. Because of the gas heating while being filled you may find less then the cylinders rated pressure when it cools. If you leave your cylinders to be fill I will top to rated pressure when gas has cooled.

A certified custom gas blender (TDI #7595) will blend any mix you wish with proof of proper certification for use of the mix you request. While there are shops out there that will hot mix we refuse to hot mix. For a Nitrox mix expect to leave overnight or drop off early and pickup a few hours later. For Trimix we require 24 hours to fill your request. There is no need to dump your old mix as in most cases we can top your old mix to the breathing gas you request.
