Duplex filter for liquid filtration

The BOLLFILTER Duplex Type 2.04.5 is a filter used for the filtration of liquids, such as water, oil and liquid fuel. It can be installed in the suction or pressure lines to protect parts of the system installed upstream, such as valves, pumps, sliders, pressure gauges or pipelines and, thus, protects these against contamination and silting.
BOLLFILTER Duplex Type 2.04.5 features
The BOLLFILTER Duplex Type 2.04.5 filter consists of two filter chambers. The filter elements used are star or basket sieves, which can remove particles in liquids of 10 micron to 5 mm filter fineness. In order to retain the finest metallic solid bodies in the filter element, as required, magnetic bars can also be installed in the sieve elements.

BOLLFILTER Duplex Type 2.05.5 is switchable. As such, the system continues to run without interrupting operation. Switching off the filter chambers at the same time is excluded.

Fully API 614 compliant, this filter maintains a proper balance of cost and performance. The compact size and ease of operation make this and ideal choice for most oil applications.

The ideal duplex filter for separating solids/dirt particles from gases.

Duplex coalescer gas filter for generators and turbines
The high-performance duplex filter BOLLFILTER Duplex Type BFD-C HD is used as a gas filter and coalescence separator in chemical and petrochemical plants, in the offshore industry, and in the power plant sector. This filter is primarily used for filtering fuel gas and seal gas. In cases of heavy contamination,
the filter is combined with a pre-separator, e.g. a cyclone or cyclone demister, to separate off solids and liquids. A rapidly rotating flow of gas is required in order to separate out small and lightweight particles. Therefore, the cyclone is designed under actual operating conditions in order to achieve the most efficient separation possible.
