Hollis DC7 500SE Regulator With Maxflex Hose

The new 500SE is a perfect blend of old school design and new technology. It features a servo controlled valve to ensure precise airflow and unmatched performance for air and trimix divers in a side exhaust setup. This design is a refinement of the original "lever-servo valve" that was created 35 years ago. The overbalanced diaphragm first stage ensures optimal hose routing for both backmount and sidemount users, as well as top-level performance regardless of depth.

The DC7 First Stage is a high performance over-balanced first stage that delivers increasingly greater intermediate pressure as depth and gas density increase, providing exceptional gas delivery even in the most extreme conditions. Fixed hose routing makes it an ideal choice for both backmount and sidemount configurations. Additionally, environmental sealing prevents internal corrosion, contamination, and icing of the first stage, making it incredibly durable. It is also designed to meet the rigorous CE standard for coldwater performance.

The 500SE's use of a servo controlled valve marks a significant advancement in technology for both air and trimix divers. The design ensures precision airflow and unparalleled performance in a side exhaust configuration. This innovative technology builds upon the original "lever-servo valve" that was introduced 35 years ago, showcasing a perfect blend of old school craftsmanship and new school advancements.

In addition to the servo controlled valve, the overbalanced diaphragm first stage of the 500SE offers ideal hose routing for both backmount and sidemount users, providing top-level performance regardless of depth. The DC7 First Stage is designed to provide progressively greater intermediate pressure as depth and gas density increase, ensuring superior gas delivery under the most extreme conditions. Its fixed hose routing is suitable for both backmount and sidemount configurations, making it a versatile choice for divers. The environmental sealing of the first stage prevents internal corrosion, contaminants, and icing, ensuring its durability and reliability in varying conditions.

The technological advancements of the 500SE, such as the servo controlled valve and overbalanced diaphragm first stage, demonstrate a commitment to providing divers with the best possible equipment for their underwater adventures. With its precision airflow and unmatched performance, the 500SE is poised to set a new standard for diving equipment, ushering in a new era of excellence for divers of all levels.
