Interspiro Divator RS4 Regulator – 4-Port + DP1, DIN, PSI

The Interspiro Divator RS4 4-Port + DP1 Regulator is a rugged, high-performance first-stage regulator designed for public safety diving, professional diving, rescue operations, and surface-supplied air applications. This configuration combines the versatility of the Divator RS4 first stage with a dedicated Interspiro DP1 surface-supply connection, allowing the diver to operate from a conventional SCUBA cylinder or integrate with the Divator DP1 high-pressure surface-supply system.

Built for demanding dive environments, the RS4 provides exceptionally high airflow while maintaining stable intermediate pressure despite changes in cylinder pressure or diving depth. Its robust, shock-resistant construction is designed for professional users operating in cold water, contaminated-water response environments, current, low visibility, and other challenging conditions.

The 4-port configuration provides four low-pressure outlets for configuring the regulator with equipment such as a Divator or other compatible full-face mask breathing hose, octopus regulator, drysuit inflation hose, and BC inflation hose. A separate high-pressure outlet can accommodate compatible instrumentation such as an Interspiro HUD or other HP device.

This version is factory configured with a DIN cylinder connection, PSI pressure gauge, and DP1 surface-supply connection, making it an excellent choice for public safety dive teams that want a single regulator configuration capable of supporting both conventional SCUBA operations and Interspiro DP1 surface-supplied diving.

DP1 Surface-Supply Capability

When connected to the Interspiro Divator DP1, the RS4 becomes part of a lightweight high-pressure surface-supply diving system. The DP1 delivers cylinder pressure from the surface to the diver, where the RS4 regulates the breathing gas at the diver. This eliminates the need for the surface attendant to continually adjust intermediate pressure as depth changes.

The lightweight DP1 supply hose can also serve as the diver's safety line, providing public safety dive teams with a compact and rapidly deployable alternative for operations where surface-supplied breathing gas is preferred.

Ideal For

Public safety dive teams, fire department dive teams, sheriff and law-enforcement dive teams, search and recovery divers, rescue divers, professional diving operations, and agencies building an Interspiro Divator full-face mask and DP1 surface-supply system.
