OLD SCHOOL. NEW TECH.

The new 500SE utilizes a servo controlled valve to provide precision airflow and unparalleled performance for both air and trimix divers in a side exhaust configuration. To achieve this, we have perfected the original "lever-servo valve" we designed 35 years ago. Overbalanced diaphragm first stage also provides ideal hose routing for both backmount and sidemount users and optimum performance regardless of depth.

 
  • Pneumatically balanced servo valve system
  • Patented Orthodontic Mouthpiece for comfort and reduced jaw fatigue
  • Standard with 30" maxflex hose
  • Easily disassembled without the use of tools and underwater if necessary
  • Left or right positioning - no upside down
  • Boltsnap tie point

High performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions. 

The DCX high-performance, over-balanced first stage, provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions. Based on the DC1 the DCX also has a 5th low pressure port that points directly down from the first stage providing easy hose routing for backmounted doubles, sidemount or even for recreational divers. It differs from the DC1 in that it is lighter and protected by a super hard PVD* (Physical Vapor Deposition) coating. PVD is by far the most durable coating available and will out last any traditional finish. 

  • Swivel turret allows for ideal low pressure hose routing
  • Environmental sealing prevents internal corrosion, contaminants, and icing of the first stage
  • Designed to withstand the rigorous CE standard for coldwater performance 
  • More streamlined internal design makes it lighter weight than previous designs 
  • PVD* "industrial" plating.
  • Unique 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. 
  • 2 HP ports and 5 LP ports for optimum hose routing 
  • 5th port allows for side-mount or twin cylinder set ups 
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping salt and contamination out.

*Physical Vapor Deposition (PVD) is a time tested proven technology that has been used for decades in other industries and is now available for specific Hollis products. PVD is a collective set of processes used to deposit thin layers of material, typically in the range of few nanometers to several micrometers. This state of the art process provides a superior alternative to traditional “Chrome Plating”, is environmentally friendly and provides longer lasting durablity.
