New 730 series with europan profile!

Aignep is launching the new 730 series, quick couplings oriented to the energy saving thinking: thanks to the special construction off the shutter, 730 series allow the improvement of 25% of the flow rate if compared to the standard one with the same profile .The shutter have been designed with the same components and dimension, but their position have been improved, this allows to avoid obstacles that can obstruct the flow. Accordingly, is possible to obtain more flow power using less compressed air energy. The new 730 series have been launched in Hannover Messe 2017 and they will be effectively on the market in the next few months. At the moment this technology is applied only on the German profile, but it will be enlarged to all the most important profiles (Italian, Swiss, B12 ISO suitable for the North American market) and improved for all automatic quick couplings of Aignep.

Ad hoc project

The project of the special shutter is the result of a near one year of studies and analysis conducted by Aignep’s R&D department. The outcome is the absence of any kind of obstacles and interferences to the flow of fluid improving the flow rate, Aignep did this by applying a better disposition of the components inside the shutter.

From a esthetical point of view, thanks to a special molding, the shape of the shutter is narrow and clean. In fact, order to improve the flow rate it has been necessary to adopt a different material from the standard one. Therefore there has been a material change from turning machine worked brass to diecast zamak (molded and nickel-plated), with the aim to obtain more flow resistance and avoid condensate.

A different disposition of the inner springs has been important to avoid obstacles to the flow: they are now mounted along the inner perimeter of the body, instead of in the center. The achievements can be shown in the fact that this new 730 series allows the same profile to ameliorate the standard flow rate, reaching 2.550 Nl/min that are far more efficient from the market standard 1.900Nl/min.

Another advantage is that this 730 series can be applied also in vacuum application: contrariwise of the classic model, the special shutters allow this quick coupling allows a bidirectional management of the flow rate.
