Nautec-Silencer Every cylinder inspection facility knows the problem, visual and hydrostatic inspections. Cylinders must be drained, with the accompanying assault on ones auditory nerves. With the MicroMaxx filtration system as a base, Nautec has developed and refined an effective noise reduction system that ensures operational safety requirements. When a pressure vessel is rapidly emptied, temperatures well in of excess -40C or -40F, are created. Conventional “Silencers” have no filtration system. Water vapour inside the cylinder can turn into ice crystals. Cylinder particulate can be ejected with sufficient force to cause personal injury. By installing the MicroMaxx filter in a muffler or silencer system, potentially dangerous loose cylinder particles and ice crystals are contained. As well, the decibel rating of the escaping air is reduced significantly. The decibel reduction will vary with the amount of air left in the cylinder, how far the knob is opened and marginally, with the valve air flow design. The Nautec Silencer consists of three parts: 1). A connection piece to the cylinder – G5/8” that will accommodate valves up to 300 BAR. 2). A replaceable filter element, that contains air borne particulate and ice crystals. 3). A silencer pipe that attaches to the connection piece. The filter element is identical to the element used in the MicroMaxx system. It mounts in the silencer pipe and o-ring seals to the connection piece, creating a sealed unit. No unfiltered gas can escape. This creates an element of safety for the operator within a unit that can have components easily replaced. An aftermarket “A-Clamp” or “Yoke” adapter is available.

MICRO-MAXX-Filter® for NAUTEC Valves ¾“NPSM and M25x2 Cold water diving can cause “internal icing” in breathing air. The effect intensifies with minor increases of the percentage of water vapour in the breathing mixture. The first system point to be affected is the water protection or dip tube. This is the first point of “air relaxation”. With the right conditions, steel cylinders will rust and aluminum cylinders will oxidize. Micro particles can lead to air contamination and affect the diver physiologically and compromise equipment integrity. The Nautec filter element is made from a hydrophobic PE plastic, the material is a poor conductor of heat and physiologically harmless. Further, it is temperature resistant, impact resistant and chemically neutral. By filtering out the smallest particles in the range of 3 to 5 thousandths of a millimetre (3-5 μ) and being impermeable to water, your personal safety against icing is ensured. The MicroMaxx Filter is intended to replace the conventional plastic or brass water protection or dip tube. It has been designed to fit all Nautec Valves! There is also a model with an M 6 x 0.75 metric connection thread for valves made in Italy (Halcyon/Scubapro, Thermo, etc.). What are the advantages of the Nautec-MicroMaxx-Filter® ? • Installation of the filter on almost all cylinder valves without additional, expensive adapters required! • 25% improved filter performance with a new surface geometry! • A special screw connection, developed by Nautec, gives high strength to withstand pressure surges, even when filling from storage tanks. • Cost saving! Easy replaceable filter element. Simply unscrew the old filter element and screw on a new one. NAUTEC recommends inspection of the filter element annually, at every visual inspection. Heavy use or questionable air sources will merit more frequent inspections. The filter must be replaced every five years at the time of hydrostatic testing. A cylinder valve, with an installed MicroMaxx filter system, should be physically marked to avoid damage at the time the valve is removed. The filter element must be replaced immediately: • when contaminated with compressor oil (visual inspection or olfactory test) • when the zinc white colour has changed in any way (a brownish color would indicate rust from steel cylinders). • when mechanical damages occur, such as when removing the valve without due care.

Tank valve specifically designed for sidemount diving. Tank neck thread is DIN EN 144-1 (M25x2). Nautec SLS-L and SLS-R valves are standard shut off devices in accordance with DIN EN 12209-2 (G 5/8“), for an operating pressure of 232 bar. Depending on the model, the shut-off mechanism is arranged either 90° to the left or 90° to the right of the regulator connection. On the opposite side of the knob there is a about 35 mm valve body extension put into place. This prevents the bungee loop from slipping off. Only 1 first stage can be connected. Equipped with a orange “Full-Metal-Core-Double-Wheel-Rubber-Knob” (for maximum grip).
