Filtry spływowe FRS Atos

Return filters are used to protect pumps and the entire hydraulic system against contaminants in the medium. FRS filters are low pressure filters, they can operate at a maximum pressure of 8 bar. FRS are designed to be installed  on the return line of the hydraulic system (at the top of the oil tank).

Maximum working pressure: 8 bar, maximum flow: from 45 to 550 l/min, microfibre filtration rating: 12 or 27 μm

The FRS series of filters includes 4 sizes and many variants regarding the sizes and types of oil ports and filter cartridges. The material of the filter elements is made of microfiber. The filtration rating, according to ISO 16889, for βx (c) ≥ 1000 is 12 or 27 μm. In addition, these filters can be adapted to the needs of the installation and equipped with clogging indicators and by-pass valves.
