MERG-1652E-DFH

The Mec Merg-1652E-DFH and Mec Merg-1652E-DFF 3/4 NPT mount second regulators are high-performance scuba diving regulators designed for use in a wide range of diving conditions. These regulators are part of Mec's Merg series, known for their reliability, ease of use, and efficient gas delivery.

The Mec Merg-1652E-DFH and Mec Merg-1652E-DFF share many common features. Both regulators are constructed of corrosion-resistant materials, including a brass body and stainless steel components. They feature a balanced diaphragm design, which provides superior breathing performance and reduces inhalation effort. The first stage of these regulators is a screw-in type, with a 3/4 NPT thread and a pressure range of 9-13 psi.

The Mec Merg-1652E-DFH and Mec Merg-1652E-DFF have some key differences as well. The main difference lies in their second stage designs. The Mec Merg-1652E-DFH comes with a dynamic-flow second stage, which offers a more natural breathing experience by providing a constant and consistent flow of gas throughout the entire breath cycle. This design is ideal for divers who prefer a smoother breathing response.

On the other hand, the Mec Merg-1652E-DFF is equipped with a demand-flow second stage. This design delivers gas only when the diver inhales, making it a popular choice among those who prefer a more responsive breathing experience. The demand-flow second stage also features an adjustable inhalation effort knob, allowing divers to customize their breathing resistance for optimal comfort.

* A durable, ergonomic venturi-operated purge button that makes it easy to clear water from the second stage

* A high-flow exhaust port that minimizes bubble creation and improves overall performance

* A DIN adapter for use with DIN tanks (sold separately for the DFF model)

* A protective rubber boot to shield the regulator from impacts and scratches

In summary, the Mec Merg-1652E-DFH and Mec Merg-1652E-DFF 3/4 NPT mount second regulators are versatile and high-performing scuba diving regulators. The DFH model offers a more natural breathing experience with its dynamic-flow second stage, while the DFF model delivers a more responsive breathing experience with its demand-flow second stage. Both regulators are built to last with corrosion-resistant materials and feature a balanced diaphragm design for efficient gas delivery.
