Specifications

The SRFA series filter is composed of two single bowl filters, a 2-position 3-way directional valve, by-pass valve, indicator and diffuser. It is simple in structure and easy to use .It can be installed on the top, at the side or in the bottom of the tank; there is by-pass valve and contamination indicator in it, for protecting the hydraulic system safety. The feature of this filter allows continuous operation even during replacing element, which is clogged by contaminant. When the filter element is clogged by contaminant that results in the pressure reaching to 0.35MPa, the indicator will give signals. At this time, turn the directional valve in order to make the other filter work then change then change the element.

If the filter cant's be changed in time that make the pressure reaches to 0.4MPa,the the by-pass calve will open to keep the system safety. The filter has check valve, so when it was installed at the side or in the bottom of the tank and change element, it won't let the oil flow out of the tank.

The diffuser is installed under the filter bowl, which makes the medium flow stably into the tank.

The filter element is with high filtration accuracy, low initial pressure loss and high dirt-holding capacity. Filter ratio β3,5,10,20＞200, filter efficiency n≥99.5%, and fit the ISO standard.
