The Hollis DC1 1st Stage Regulator is a Streamlined Over Balanced Diaphragm Regulator that provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions. The diaphragm membrane on the Hollis DC1 1st Stage Regulator transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. The standard Diaphragm Regulator does allow water into the Mainspring Chamber so that the Diaphragm can perform this Transmission of Pressure Changes.

With the Hollis DC1 1st Stage Regulator there is a Secondary Environmental Diaphragm Membrane that Seals off the Spring Chamber keeping the First Stage completely Sealed off from the Environment adding a Second Layer of Corrosion Resistance and the Environmental Sealing Prevents Icing of the First Stage, allowing the Regulator to withstand the rigorous CE standard for coldwater performance.

The Hollis DC1 1st Stage Regulator has 5 Low Pressure Ports with 3/8" Threads and 2 High Pressure Port with 7/16" Threads The LP Ports are mounted on a Swivel Turret that allows for ideal low pressure hose routing. One Low Pressure Port points directly down from the first stage providing Easier Hose Routing for Back Mounted Double, Side Mount Cylinders or even for Recreational Divers. The Hollis DC1 1st Stage Regulator is manufactured from Marine-Grade Chrome Plated Brass and is Nitrox compatible to 40% out of the box. The Regulator weighs 34.88 oz (989 g), is available in a Yoke or DIN Cylinder Connection comes with a CD Owner's Manual and is covered by a 24 month limited warranty.

Miflex Xtreme Low Pressure Braided Regulator Hoses
Miflex Xtreme Low Pressure Braided Regulator Hoses feature an external nylon safety braiding designed to resist the snags and abrasions that divers can often encounter. The patent Pending XTREME double braiding also resists UV rays out of the water, thus extending the lifespan of the hose.

Unlike traditional hoses, the XTREME nylon safety braiding is not simply pushed over the hose fittings. Instead the braiding is tightly bound and fixed to the hose core by stainless steel or brass sleeve.
