Auto-line© R Automatic Filters LR

HiFlux Auto-line filters are designed as compact self-cleaning automat-ic filters made from stainless acidproof EN 1.4404 steel with a wide range of applications. The robust construction of the filter makes it suitable for cleaning practically all liquids, including paint, lacquer, lubricat-ing oil, bitumen, HFO, grease, paint, toothpaste, water, fermentation liquids, petrol, syrup, condensate, CIP liquids, antibiotic suspensions, many types of waste water etc.

The filter is used when an automatic continuous cleaning process is required. As the impurities are being concentrated in the filter until it is drained away while the filter is still in operation the liquid loss due to cleaning is minimal.

The filtration principle is based on filter elements, with the dirt particles being retained on the inside surface of the filter element.

In the cleaning process the dirt is scraped into a sludge chamber from where it is drained away from the filter at appropriate intervals. This results in a defined and absolute cleaning of the filter.

Drainage is controlled individually, which means that the loss of medium is reduced to an absolute minimum in connection with sludge removal.

When cleaning a number of knives scrape the surface of the filter element leading the sludge into the sludge chamber in the bottom of the filter. The principle is that of a rotating screw. This principle means that the filter gains a large dirt capacity due to frequently scraping. The flow through the filter is continuous during the scraping period which means that the filter can work continuously and the flow is not interrupted.

Drainage of the filter takes place through the bottom valve which can be set to be activated after a certain period of time. This results in the sludge being concentrated before it is pushed out of the filter. Hence the product loss is reduced to a minimum.

Draining usually takes place within a period of 1 -3 seconds where a minor fall of pressure can occur. The flow in the filter will only be reduced by about 5 -10% during the short period the drainage takes place.

The filter is available as R-E version where the scraping process is driven by a gear-motor or as the R-P version, where the scraping process is driven by a pneumatic actuator.In the design of the filter importance has been attached to making the construction robust and reliable. By limiting the number of moving components, wear and maintenance requirements are minimized. The simple construction makes the filter very easy to service hence there is no need for external service assistance or special tools. Furthermore the compact design of the filter is making it suitable for situations where the height is a limitation.

For other possibilities see Auto-line Automatic Filters, KS and AKS 137 filters.

Special versions can be supplied according to customer requirements -typically other temperature and/or pressure levels.

Capacity: (at a viscosity of 1 cSt and as a pressure filter)

*) Capacity in m³/h / micron

The filter should only be installed as a pressure filter in systems which have a positive overpressure (the surroundings must be taken into consideration).
All Auto-line filters are standardly produced according to the pressure equipment directive 97/23/EC article 3, section 3, but can be delivered with approval according to category I, II, III or IV. Auto-line filters can be delivered with approval for use in explosive atmos-pheres (zone 1/21) according to directive 94/9/EC.
