Self-cleaning filter saves on downtime
8 Jan 2003
Building on the success of its Eco self-cleaning filter, Russell Finex has introduced a horizontal version that features significant improvements in terms of easier operation and maintenance.
The major benefit of the filter is that only one person is needed to dismantle and re-assemble it for screen change, product changeover or cleaning.
But what really differentiates the filter from competing machines like bag filters, or disc and blade self-cleaning filters, is its SpiroKlene continuous screen cleaning mechanism. Fitted with scraping elements in product-compatible materials, the SpiroKlene assembly acts in the manner of an Archimedean screw, positively driving oversize material away from the filtration area towards an optional automatic discharge system.
The continuous removal of material from the screen area in this way ensures consistent flow rates and low differential pressure. Rotating at around 10rpm, the cleaning shaft requires only 'O' ring or lip seals.
The reusable perforated stainless steel microscreen gives accurate separations down to 10µm, while wedge wire screens are also available for higher capacity filtration where required. Magnetically detectable screens are also available for the food industry.
The range of models available can handle throughputs from a few hundred l/hr up to in excess of 100 000 l/hr. Jacketed models are also available to maintain product temperatures.
