Close mini pleat filter diffuser. It is composed of a filter for laminar flow coupled with a circular inlet cover: 4 handles allow to easily separate the two parts, while the tightness is assured by a gel gasket. This system, patented at European level (n° 2149405), permits to speed up the filter replacement operations because it avoids to disconnect and then connect again the flexible pipe and it avoids also to recalibrate the adjustment damper. Different versions are available according to the installed accessories. It is commonly used in air controlled contamination environments, also in critical applications like clean rooms with laminar flow. 

Close mini pleat filter diffuser efficiency:
