Description
The DIR set combines two V2 ICE first stages with two TEC1 second stages, one on a long 2.10 m hose and one on a short 61 cm hose. The first stage is a balanced diaphragm design with a dry chamber that seals the working diaphragm and prevents freezing in cold water; this protection is also an advantage in heavily silted water. It is made of marine brass with a high-quality frosted chrome finish, and the hoses are arranged in a V shape. Its breathing performance exceeds the requirements of the latest EN 250A standard and gives smooth breathing in all conditions.
The streamlined configuration is popular for twin tanks and stage tanks. Neatly routed hoses and easy valve access let you use the full hose length when needed, while free space behind the head and a better position in the water (head-up design) add comfort and safety.
The TEC1 second stage is a downstream demand valve with venturi and breathing resistance adjustment. A heat exchanger reduces the risk of icing in cold water, and a breathing resistance of about 1 J/l makes breathing easier and helps reduce air consumption. TecLine regulators are trialled in demanding conditions from icy Polish lakes to caves and tropical waters, and after assembly and tuning every regulator is checked by two independent technicians. Suitable for nitrox up to EAN40 (40% O2).
