The concept is a fully automated protection filtration with relatively low flow rates. For example, with machine and plant systems for sprinkling or spraying that require a powerful and proven backflushing filtering system that works at an extremely high efficiency level is safe during use and permanently cost-effective.

The BOLLFILTER Automatic Type 6.04 is used for the filtration of the following applications: offering high quality yet low maintenance despite low initial cost.

Cooling water, Industrial Water, Process water, Seal water and Spray water

Other Applications

Cooling water & coolants, Sprinkling water, Washing and cleaning water, Effluent Water for snow production, are just a few of the many applications that can be accommodated with the BOLLFILTER 6.04.

Effluent water, Snow gun water and Rinse wash water

Technical Considerations

With a large filtration area for maximum efficiency, the Bollfilter 6.04 filters to 200 microns at flow rates between 0.5 and 18 m3/h and at pressures up to 16 bar.

The Bollfilter 6.04 in its 200 micron form is now available from stock supplies in the UK and will be on short delivery time due to the single model in a fixed format.

On initiation of the backflush, the drive motor is turned on. This turns the rinse wheel on the individual filter candles. At the same time the sludge drain valve is opened. This results in a high axial flow in the filter candle and the retained dirt particles are flushed out and passed through the tube from the filter. After about two revolutions of backflushing the control switches the drive motor off. The sludge drain valve is closed. The filter is cleaned. By flushing the individual filter candles, the full flow rate is maintained even during the regeneration phase. A technological high-quality & cost-efficient Innovative filtration system made in Germany.

The BOLLFILTER Automatic Type 6.04 is equipped with built-in electronic controls, an LED display for operation, backflushing and breakdown. BOLL & KIRCH ensure very fast delivery and easy installation of the filter within the unit that is to be protected. The BOLLFILTER Automatic Type 6.04 has a robust and suitable compact design. The filter is made of only a few components, allowing easy access to the internal functional units and a high level of freedom for maintenance. All pressure parts, the cover and the housing of the filter, are made from aluminum and all internal parts are made of lightweight plastic. The removal of the outer function units is easy to do and allows maintenance of the filter without using any special tools.
