Vacuum self-cleaning drum filter

A permanent filtering net which removes metallic particles from coolants is featured on Spring V, a self-cleaning drum filter which works by vacuum system

Spring V is a self-cleaning drum filter which works by vacuum system, with a permanent filtering net which removes metallic particles from coolants.

Spring V can process up to 200L/min.

of neat oil and up to 400L/min.

of emulsion.

The filtration efficiency can be customised according to clients' needs.

The self-cleaning filters of the Spring Series are suitable for various kinds of machine tools such as machining centres, deep drilling, transfer and grinding machines, lathing, high pressure processes with special tools and combined system machines.

Spring V is particularly suitable for processes with neat oil and where high levels of filtration are required.

This makes it particularly suitable to the diverse requirements of the machine tool industry in general as well as the automotive industry.

Filtration of the liquid takes place across the drum thanks to the difference in pressure which exists between the inside and the outside of the drum.

Spring V uses the vacuum created by a pump within its drum to optimise its efficiency: the pump aspires the air inside the drum thus creating a vacuum and increasing pressure on the filtering net.

This allows for an increase in throughput and prolongation of the clogging-time on the filtering net which increases the thickness of the cake on the net thus allowing for elevated levels of filtration.

In the course of time the filtering net can maintain its efficiency thanks to a double, jet-stream cleaning system.

The absence of a scraper blade on the filter net avoids possible damage of the same net.

A double scraping chain removes the waste deposit.

This completely automated system is run and monitored by an electric device with a synoptic LED and a mini PLC.
