With over 1,200 installations around the world, Outotec Larox® PF Filters are the benchmark for reliability and efficiency in a wide range of applications.
The individual filter plates have single-sided filtration areas of 1.6, 2.5, 6, or 9 m2, depending on the model and an operating pressure of up to 16 bar. The plates are stacked vertically to give a total filtration area of 1.6–252 m2.
Consistent Performance and Simpler Maintenance
Outotec Larox PF Filters are fully automatic, operating either with a stand-alone panel and integrated PLC or through a distributed control system. Automation extends beyond simple filter sequencing to process control, ensuring consistent results under varying process conditions. After each cycle, the filter cloth is passed through high-pressure water sprays to remove any embedded solids.
This maintains cloth permeability and consistent filter performance by ensuring every chamber has equal cloth resistance, and also extends cloth life. Our single-cloth system makes maintenance simple and quick, with cloth changeover typically taking as little as 30 minutes and requiring only two technicians. Furthermore, a thorough cloth inspection can be carried out without the need for equipment shutdown.
