Product Description

The Dive Perfect Edge First Stage Regulator is for the discerning technical diver who wants the benefits of five low pressure ports all mounted on a rotating turret, resulting in optimal hose routing while eliminating sharp bends in the hose. This is a feature rich 1st stage regulator with a definitive blend of style, ruggedness and high performance, at a moderate price.

Every detail of this product has been carefully designed to deliver a regulator package of the highest quality with improved safety for technical divers. These regs meet the tough CE EN250 European standards, and are cold water and Nitrox ready.

Dive Perfect Edge 1st Stage Regulator Features and Benefits

The Dive Perfect Edge FS-8045 DIN ICE 1st Stage Regulator features five low pressure ports all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose.

The first stage regulator is supplied in 300 bar DIN configuration for added safety and lightness for travel. The environmentally sealed chamber 1st stage regulator is suitable for cold water use (below 10°C / 50°F).

The first stage regulator is compatible with EAN40 out of the box. It can be cleaned for use with 100% Oxygen.

The second high pressure port makes it easy to add a dive computer pressure transmitter. The fourth and fifth low pressure ports make it easy to add a drysuit inflator hose.

Dive Perfect Edge FS-8045 DIN ICE First Stage:

  • DST style first stage.
  • Highly polished bright chrome plating.
  • Compact cylindrical body with LP ports on a rotating turret and angled for optimum hose routing.
  • 5 angled medium pressure ports, 5 x 3/8"-24 UNF.
  • 2 angled high pressure ports, 2 x 7/16"-20 UNF.
  • Over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth.
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out

Dive Perfect Edge First Stage Technology

Over-balanced Diaphragm Design

The heart of any regulator is the first stage. The Dive Perfect Edge FS-8045 DIN ICE 1st Stage Regulators utilise an over-balanced diaphragm design. In an over-balanced first stage design, the inter-stage pressure in the hose increases faster than traditional balanced models as a diver descends to greater depths. This increased inter-stage pressure compensates for the increased density of your breathing gas by allowing a larger volume of gas to flow through the system on demand. The result is superior breathing performance regardless of depth.

Environmental Dry Sealing System

Standard on the Dive Perfect Edge FS-8045 DIN ICE first stages is the Environmental Dry Sealing System. This system serves a number of purposes, including the prevention of ice build up on the main spring that can occur when diving in extremely cold water. Dry sealing the first stage also acts as a safeguard against the entry of contaminants and silt into the main spring chamber, and eliminates the need for messy silicone oil or grease filling inside your regulator.

The Environmental Dry Sealing System enables the regulator to meet the European Standard for cold water regulators (as defined by CE EN250), which means that the regulator has been certified for use in water as cold as 2 to 4 degrees Celsius (35.6 to 39.2 degrees Fahrenheit). If you dive primarily in cold/temperate waters, like in Southern Australia, you need to make sure that the regulator you're getting is suitable.

The Environmental Dry Sealing System also comes into its own if you'll be diving in waters that are silty, sandy, or high in dissolved solids. The environmentally sealed regulator prevents any salt water from entering the first stage, which assists to keep it breathing within specs over an extended period of time.

300 bar DIN Cylinder Connection

DIN regulators are used by technical divers and are mandatory in Europe for safety reasons as the O-ring is captured on the regulator side rather than the cylinder valve. DIN regulators are more streamlined than INT/Yoke/A-clamp regulators and also lighter than the equivalent Yoke regulators, which is great for the travelling diver. Yoke regulators are generally limited to 240 bar (3500 psi). These DIN regulators can be used on up to 300 bar (4350 psi) cylinder valves, and are more suitable for demanding diving situations like technical diving, especially in environments like caves and wrecks where a bump to a Yoke valve could cause a serious gas leak. Most cylinder valves today are DIN/K valves where, using an 8 mm Allen key, an insert can be screwed in and out switching the valve from DIN (without the insert) to K/INT/Yoke (with the insert).

Exceeding CE EN250 Standard Performance

The Dive Perfect Edge 1st Stage Regulator meets the tough CE EN250 European standards. This means the regs have been tested on an ANSTI wet breathing simulator, which measures how much effort — "work of breathing" — it takes to move air through a regulator as it is subjected, underwater, to a precise series of depths and breathing rates.

Tests are performed at a high-pressure supply of 75 bar, at a rate of 25 breaths per minute and a tidal volume of 2.5 litres, to conform to European test standards. Per industry practice, the regs are tested in the face-forward position, and regs with breathing adjustments are set at the wide-open/no-free-flow point.

The simulator pressurises the test chamber to simulate depths of 50 metres (165 feet) of seawater. Each "breath" by the machine moves 2.5 litres of air through the regulator, and this is done at breathing rates of 15, 25 and 30 breaths a minute. These precisely measured volumes of air — 2.5 litres multiplied by the breathing rate — are called Respiratory Minute Volumes (rmv).

These regs have achieved better than 62.5 rmv @ 50 msw to meet the European conformance standard EN250. The fittest diver would be hard-pressed to keep up for more than a couple of minutes at this breathing rate and these regs will still perform well in even more-extreme conditions.
