Description
The DIR set is designed for twin-tank diving: it consists of two R5 TEC first stages, two TEC2 second stages (one on a long 2 m hose and one on a short 61 cm hose) and a 52 mm pressure gauge. 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. The regulator is popular with different types of wing.
The TEC2 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 CE certified and tested to EN 250A, and are also trialled in demanding conditions from icy Polish lakes to caves and tropical waters. Suitable for nitrox up to EAN40 (40% O2).
