This is a prototype balanced regulator for use with the diving apparatus we designed in conjunction with our client.
A balanced regulator is designed to maintain a similar effort to draw air from no matter what depth you are diving at. Unbalanced regulators will increase the breathing resistance as the depth gets greater. A balanced regulator becomes more advantageous when diving at greater depths.
As we were designing a prototype, our design did not need any tooling and was able to be made purely by machined and fabricated parts.
