BOLL Duplex Filter TYPE 2.04.5 with flange connections DN 25 – DN 80 available with heating APPLICATION Filtration of all liquids. For installation into suction or pressure pipework to protect plant components (valves, pumps, pressure gauges, nozzles etc.) preventing accumulation of dirt and sludge. OPERATION The Duplex Filter 2.04.5 allows change-over during operation without pressure-loss. The filter is compact and easy to maintain, requiring only manual cleaning when maximum allowable pressure drop is reached. When maximum pressure drop is reached the standby filter chamber is brought on line simultaneously as the dirty one is isolated by means of the change-over valve. After venting, the dirty element can be removed, cleaned and refilled to be the standby filter TECHNICAL CHARACTERISTICS • Switch change-over valve to clean • Filter housing of cast iron or ductile filter chamber • Release pressure in the contaminat- ed filter chamber by means of vent1 Differential-pressure ∆p as function of flow Q with oil of viscosity 50 cst and filtration degree 40 µmicrons. ing screw • Lift the cover of the contaminated filter chamber • Remove filter element OPTIONAL ACCESSORIES • Soak filter element in cleaning fluid, iron; internally nickel lined for water application • Change-over valve of cast iron; water filters rubber-lined • Optionally star-pleated or basket filter element, star-pleated ele- ment also available as disposable filter element Differential pressure indicator type • Filter fineness: 10 microns to 5 mm 4.36 can be supplied fitted at factory. • Operating pressure The filter elements can be fitted with For details see operating instructions cast iron up to 16 bars magnetic bars. manual ”maintenance and servicing”. ductile iron up to 25 bars
