3100 Regulator

#RG3100

DISCONTINUED: Nov 1, 2012

Five low pressure ports on the 3100 Regulator gives divers ultimate flexibility in hose routing. This is especially beneficial to the backmount technical diver where the need for a streamlined reg configuration can cause undue stress on the hoses.

Our 5th LP port is located on the top of the turret and we designed it with safety and convenience in mind. The port is slightly convex and slotted on each side to accommodate an 11/16 wrench for securing the turret while loosening the LP hose. This makes it easy to change the hose without concern of loosening the turret. Please click on TIPS to the left for suggestions on hose lengths when using the 5th port.

The 3100 Series Regulator is the same high-performance, workhorse reg as the former 3000. Designed for the challenging world of technical diving, this reg is certified to CE EN 250 and approved for cold water 300 bar [continued]

service, having passed the most rigorous of tests.

A pneumatically balanced design delivers gas at a constant pressure so work of breathing remains effortless independent of depth or tank pressure. A diaphragm first stage means regulator parts are not exposed to the environment, protecting it from contaminates and debris. An ergonomic venturi lever is easy to adjust even with thick gloves.

An optional environmental kit protects the reg in cold weather and harsh environments. It comes standard with a 300-bar DIN connector and an additional yoke adapter. Using oxygen compatible materials and assembly processes that are today industry standard, the 3100 is suitable for oxygen use at gas pressures up to 3000 psi. **

** CAUTION: The 3100 Regulator is suitable for oxygen use only if precautions are taken. Diver must use oxygen compatible materials, keep the regulator clean from contaminants during assembly and [continued]

use and open the tank valve slowly each time the regulator is pressurized. These are normal operating instructions and safety precautions for any equipment used with oxygen mixtures above 40%. Please refer to your agency training guidelines for additional information on how to safely dive oxygen mixtures above 40%.

When routing from the right post, primary inflation (hoses cross) using our 5th port , you'll need shorter BC hoses.

  • For 12" corrugated hose you need a 18" BC hose
  • For 16" corrugated hose you need a 22" BC hose
  • The rest of the hoses are standard (LP84, LP22, HP24)
