Scuba Diving Regulators

Repair and Maintenance

The air is then sent down the hose to the second stage. Here the pressure is reduced by that same intermediate pressure, leaving air at ambient pressure.

Regulator first stages can be balanced or unbalanced.   Balanced first stages are designed to breath as easily at low tank pressures and depths up to 90ft as when they are attached to a full tank at the surface.    Most regulators provide one or two high pressure ports for pressure gauges and three or four low pressure ports for second stages, LP inflator hoses or dry suit hoses.   Second stages offer external adjustments that can be made by the diver while diving to vary the performance of the regulator. The venturri assist is a two position adjustment that creates a venturi effect to optimize breathing performance and help prevent free flows at the surface. Another type of adjustment is the adjustable air flow knob or dial. This adjustment alters the flow rate to compensate for depth changes.

All Regulators are Fully Assembled by Scuba Instructors

At Scuba.com all equipment is fully assembled by a factory trained certified scuba instructor before you receive it. Unlike other dive centers (even possibly your own local dive store) where you may find anyone, even possibly an uncertified diver, assembling your equipment. At Scuba.com a scuba instructor assembles everything and all you need to do is add air and water. See less ▴
