What pressure is an aluminum 80 scuba cylinder typically filled to?

An aluminum 80 scuba cylinder is typically filled to a pressure of 3,000 psig. This standard is used to ensure that the cylinder contains enough compressed air for a diver's needs. The aluminum 80 designation refers to the cylinder's volume, which holds approximately 80 cubic feet of air when filled to this pressure.

Filling to this pressure maximizes the efficiency and usability of the cylinder, allowing divers to benefit from longer dive times and sufficient air supply. High-pressure ratings are essential for maintaining safety and performance during dives, and 3,000 psig is a widely accepted standard for scuba cylinders of this size.

This pressure provides a good balance of safety, performance, and air volume for recreational and professional diving activities, thus ensuring that divers have an adequate supply of air while underwater.
