HEAFIL introduced the Keilimann Pocket sewing machine. By sewing the media, there is a good structure (V-shape) formed between the media. So that the air flow passed through the media smoothly, it helps avoid the turbulence and reduce the pressure drop. The good structure is beneficial to the appropriate space between bags. Additionally, it maximizes the media’s contact area with the air so that the filer media area can be full used to ensure the life cycle and minimize the energy consumption.
Besides, HEAFIL owns the most advanced pleat machine in the world. It can produce pleats, whose height can be from 12mm to 280mm. Moreover, it is with Intermittent Hot Melt Technology, which is pleasant with the air flow. The pressure drop of the filter package can be optimized and rise up steadily. In addition, the machine provides the possibility of the specialty. We can specify the air filter according to the installation space and the performance of the media. Not only meet the efficiency but also achieve the best air pressure drop , life cycle and reduced total cost.
