Auto-line© Automatic Filters L & LE

HiFlux Auto-line© filters are designed as compact self-cleaning automatic filters made from stainless acid-proof 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 lubricating oil, bitumen, HFO, grease, paint, toothpaste, water, fermentation liquids, petrol, syrup, con-densate, CIP liquids, antibiotic suspensions, paint, lacquer, many types of waste water etc.

The filter is used when an automatic continuous cleaning process is required. Because 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.

When cleaning, the scraper is lead through the filter element and scrapes the dirt into the sludge chamber. Since the scraping plunger is milled out, the flow through the filtration can continue during the scrap-ing process. This means that the filter can work continuously and the flow is not interrupted during the cleaning process.

The drainage of the filter takes place through the bottom valve, which can be set to be activated after a certain number of scrapings. Due to this the sludge is being concentrated before it is pushed out of the filter. This means that 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 re-duced by about 5 -10% during the short period the drainage takes place.

The E-type filter has an extended pneumatic cylinder, so that cross con-tamination between the liquid to be filtered and the pneumatic system is avoided.

In the design of the filter importance has been attached to making the construction robust and reliable. By limiting the number of moving com-ponents, wear and maintenance requirements are minimised. The sim-ple construction makes the filter very easy to service, hence there is no need for external service assistance or special tools.

For other possibilities see Auto-line R, 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 atmospheres (zone 1/21) according to directive 94/9/EC.
