Continuous Filtration as a Production Strategy

for High-Performance Extrusion Systems

Cofit designs and manufactures screen changers that keep the line running: the filtering surface is cleaned or renewed while extrusion continues. This reduces screen-change stops and helps keep melt pressure stable, from virgin resin to heavily contaminated post-consumer recyclate.

Three technologies: AP, a continuous self-cleaning screen changer; GorillaBelt, an automatic belt screen changer; ScrapeAway, an automatic, continuous and self-cleaning laser melt filter.

We don’t start from the machine, but from the production your line loses at every screen change.

Trusted by leading global OEMs in high-performance extrusion environments.

How Much Production Does Your Line Lose Every Year?

On high-output lines, even short manual screen changes accumulate into significant annual production loss.

Multiple stops per shift

Minutes of downtime at every screen change

Pressure instability during restart

Scrap during stabilization phase

Increased operator workload

Lower annual sellable tonnage

In continuous operations, these interruptions compound quickly.
Quantifying the impact is the first step to reducing it.

Why Leading OEMs Choose Cofit

Changing screens without stopping the line is no longer just a mechanical feature: it is a production stability choice.

For over 20 years, Cofit has been an approved supplier to Brückner Maschinenbau for BOPP lines, with more than 600 AP08 continuous screen changers installed on these lines.

Stable melt pressure

Elimination of line stops during screen change

Improved downstream stability

Reduced operational risk

Proven reliability in demanding global installations

Low maintenance

Our approach is based on engineering validation, not commercial pressure.

Structured Technical Validation for OEMs

Our structured validation reduces integration risk and builds confidence before full deployment.

Our Products for Your Extrusion Line

From heavily contaminated post-consumer and post-industrial plastics to clean materials for demanding applications, Cofit screen changers help you keep production running, with high filtration quality and limited material loss.

AP Screen Changer

For virgin material, clean regrind and regranulate, clean or semi-clean applications, including those with a low recycled content. AP is a continuous self-cleaning screen changer with two parallel filter cartridges: operator-activated backflushing cleans one cartridge at a time without interrupting production.
