Hollis Tech Configured Regulator Package

- Hollis DC7 500SE Regulator with Maxflex Hose -
Introducing the Hollis Gear DC7 Regulator, a high-performance system that combines an over-balanced diaphragm first stage with a servo-controlled second stage for exceptional airflow and precision. This regulator is designed to meet the strict CE standard for cold-water performance, and its environmentally sealed first stage ensures the delicate internal parts remain protected from contaminants like salt, sand, and chlorine.

The DC7 First Stage Regulator features a secondary diaphragm that completely seals the main spring cavity, providing excellent resistance to freezing or corrosion in icy or contaminated waters. Crafted from marine-grade brass with a black anodized finish, this DIN 300 bar (4350 psi) first stage offers four low-pressure (LP) and two high-pressure (HP) ports for optimal hose routing in both back-mount and side-mount configurations. Nitrox compatible up to 40%, this regulator requires less maintenance than models that expose internal mechanisms to contaminants.

The 500SE Second Stage utilizes a servo-controlled valve in a side exhaust configuration to deliver unparalleled performance for both air and tri-mix divers. Its innovative design ensures a gentle inhale activates the valve, providing increased airflow through multiple ports. This pneumatically balanced regulator features a large soft purge cover for easy clearing, a patented orthodontic mouthpiece for comfort, and can be configured for left or right positioning without any upside-down issues.

Designed with recreational divers and underwater photographers in mind, the side exhaust configuration keeps bubbles away from the face. Constructed from durable materials like Delrin plastics, rubber, stainless steel, and chrome-plated brass, the DC7 500SE Regulator comes standard with a 30-inch Maxflex hose for enhanced flexibility and reduced jaw fatigue. The package also includes a bolt snap tie point and an owner's manual for your convenience.
