Overview of Autofilt RF3

• The slotted-tube filter elements with filtration rates of 50 to 3,000 ∪m ensure highly effective separation of contaminating particles from the process medium.
• Automatic cleaning starts as soon as the elements become contaminated. The filtrate flow is not interrupted during the back-flushing procedure.
• A range of filters of different sizes allows flow rates of up to 10,000 m³ per hour.
• Numerous combinations of materials and equipment as well as individually adjustable control parameters allow optimum adaptation of the filter to any application.

AutoFilt RF3 cost-effectiveness

• Particle contamination in operating fluids accelerates the rate of wear of system components, pipelines and valves and often leads to their premature failure. In many cases, the use of automatic back-flushing filters leads to a significant increase in service life and maintenance intervals.
• Costs for new purchases, maintenance and waste disposal can thus be minimized.

Examples of Application

• Power stations
  Treatment of industrial water for cooling generators and filtration of sealing water to increase the service life of the turbine shaft sliding-ring seals in hydroelectric power stations.
• District heat supply
  Protecting heat exchangers from clogging and wear.
• Chemical industry
  Improving product quality by filtering process media.
• Steel industry
  Protection of nozzles and pumps during high-pressure descaling, water treatment for cooling blast furnaces and rolling mills.
• Sewage treatment plants
  During production of industrial water, filtration of a take-off of the clear run can be used to save valuable drinking or well water.
• Environmental technology
  Back-flushing filters are used as pre-filters before waste-water treatment plants (UV treatment, reverse osmosis, membrane filtration...).
• Mining
  By filtering underground, spray water of an even quality is assured. This results in more reliable operation of pumps and disc-cutting machines.
• Paper industry
  For example: the protection of spray nozzles for the screens of paper-making machines. This results in fewer failures caused by clogging and wear.
• Automotive industry Mechanical engineering Machine tools
  Cooling lubricant emulsions can be kept much longer in circulation. This eases the pressure on the environment and reduces waste-disposal and re-purchasing costs. Filtering of cooling and service water protects cooling channels and pipelines from clogging.
