Designing machinery may not be the most artistic pursuit in the world, but sometimes the issue of color can be essential even in industrial design. A number of our metal parts can be produced in a variety of colors using a powder coating process.
JW Winco has its own in-house machining facility; this provides an advantage for our customers to take an idea and create a unique customized solution through the choice of using one of our standard parts.
EN 774.1 Elesa® original design technopolymer plastic filler breathers.
These breathers prevent the build-up of a pressure drop over liquids in a tank. They are used when a tank has to be rapidly emptied. The elastic membrane insures a sufficient supply of air to prevent any vacuum build-up in the tank.
Additionally, the back pressure behind the membrane will prevent the escape of any liquid in the tank to the outside, especially during transport.
If the tank is turned upside down with the additional back pressure from the liquid, it will be sufficient to keep the outlet firmly shut.
Breather caps can be used with EN 664 or EN 664.1 filler strainers.
Resistant to solvents, oils, grease and other chemical agents.
