Paper filter ANDREAE

for paintplatecentrifugal

Andreae filters are composed of two folded, solid cardboards pieces which are glued to each other in bends. Openings on the front side are located asymmetrically against the openings in the rear wall. When the air goes through the filter, the airflow is changed in all axes. In the rear wall, created by deeper bends in the V-shape, pockets are created to capture separated liquid particles. Principle The air flow saturated with liquid particles, e.g. paints, is accelerated in the flow through the filter and multiply changes its direction. Particles heavier than air are separated from this stream by inertia. The air escapes through the outlet openings of the filter, while particles of paint are accumulated in the capturing chambers. Use By using inertia, Andreae filters capture very efficiently aerosol cloud, which is created by the spraying of all types of liquid paints and lacquers, binding agents, adhesives, epoxide resins, solvents, asphalt, gels, tar, Teflon, polyurethane, vinyl, oils, grease, glaze, etc. Generally said, filters can be used everywhere where it is necessary to remove liquid particles from blowing foggy air. Andreae filters can be used independently or as a prefilter in multi-level filtration systems. Advantages Accumulation of paint outside the airflow slows down the increase in differences in pressures and air velocity. Lifespan of Andreae filters is 3-5 times longer than that of flat, fleece filters. Filters show high stability in the air stream. The front V-shape wall prevents the reflection of overspray.
