Product Description
CRESSI AC25M MASTER CHROME REGULATOR – DIN
The Cressi AC25M Master Chrome DIN Regulator is a premium scuba regulator set designed for smooth breathing performance, flexible hose routing, and reliable operation under demanding diving conditions. It combines Cressi’s third-generation IP-adjustable balanced piston first stage with the Master Chrome pneumatically balanced second stage, creating a refined regulator system for recreational and advanced divers.
The AC25M first stage features a 360° rotating turret with five low-pressure ports, including a top-mounted high-flow coaxial port, allowing hoses and instruments to be positioned neatly without interference. It also includes Cressi’s external intermediate pressure adjustment system, which can be fine-tuned using a simple Allen key.
The Master Chrome second stage uses a pneumatically balanced design with adjustable Venturi control and adjustable inhalation effort, giving the diver more control over breathing performance. Its patented elliptical diaphragm, low-friction lever, internal heat exchanger, and noise-absorbing technopolymer body contribute to smooth and dependable airflow.
