(1) The flow rate depends on various factors: the melt viscosity, the degree of filtration, the type of contaminant and its percentage, the production line.

Continuous filtration

DUO guarantees to work in continuous way and at constant pressure.

Single independent discharge screw

Contamination collected by both filter surfaces is discharged by means of a single independent screw, which is able to carry out the contamination.

Filters replacement

DUO is designed to make maintenance operations and filter replacement easier and faster, without removing machine’s components.

Double filter

DUO uses two filters. This makes it possible to reduce the size of the filtration chamber and have large filtering surfaces, in order to increase the production volume.

Flexibility

The ability to adjust the speed of the discharge screw allows even the most contaminated materials to be handled according to the customer’s requirements.

Versatility

DUO is designed for the filtration of various types of plastics. It is designed to handle different types of contamination such as: paper, wood, aluminium, copper, etc…

Reliability

DUO and all its components, as well as the consumables, are manufactured using high quality alloy steels and wearresistant treatments are carried out on the most stressed parts. It is also designed to guarantee high resistance to pressures line (up to 350 bar).

Cleaning efficiency

The unique design of the indipended scraper disc, equipped with 6 blades, allow excellent cleaning, even at low rotation speed.

Its design also prevents contaminants filtrates from re-entering the melt.

Continuous cleaning allows to use filters longer than traditional technologies.

Amount of contaminants

DUO can be used to filter materials with high percentages of contaminants (up to 15% by weight depending on the type of pollutant).

Laser filtration

Filter discs are drilled using the latest laser technology and treated to be wear resistant.

The conical shape of the holes helps the plastic to go through them.

Cost-effective

The efficency of the continuos cleaning system, increase the life cycle of filters, reducing the amount of consumable components to be purchased.

Productivity

The continuous pressure filtration system maximises the productivity of the line.

Minimum waste

The screw rotates independently of the scraper disc. In this way the waste can be minimised depending on the contamination.

Labour

Innovative design reduces cleaning and replacement times for filters and blades.

The presence of the operator is reduced considerably.

Standard and special maintenance operations are simple, fast and can be carried out directly at the customer’s production site.

Optimisation

The possibility of adjusting the indipendent discharging screw of the speed of the scraper disc, helps the managing of highly contaminated materials.
