New ERF350 Filters up to 3800kg
of Contaminated Polymer
Feedstock Per Hour
With its newly developed ERF350, Ettlinger
Kunststoffmaschinen GmbH, manufacturer
of high performance melt filters and injection
molding machines for high shot weights,
sets new benchmarks in the filtration of
contaminated polymer feedstock.
This first model in a new, performance
enhanced generation of the ERF series is
suitable for processing all standard polyolefins
and polystyrenes as well as numerous
engineering plastics, for instance styrene
copolymers, TPE and TPU. Like all ERF models,
it is capable of removing foreign particles
such as paper, aluminum, wood, elastomers or
high-melting polymer composites containing
up to 18% contaminants. And just like all
other Ettlinger filter systems in the future,
this brand new machine can be very easily
integrated into Industry 4.0 environments.
Depending on the type and level of contamination
in the melt to be cleaned and the selected screen
size, the ERF350 achieves a maximum throughput
of 3800 kg/h in combination with the same ultra-
low melt losses. It is thus positioned much higher
up in the portfolio than the existing ERF250, which
already impresses with a maximum throughput of
3000 kg/h. This represents an increase of around

28% for the same filtration surface and typical small
footprint. This value has since been confirmed during
the first few months of practical duty with pilot
customers. Users profit from more productivity when
recycling contaminated waste plastics from industrial
or consumer sources. Furthermore, experience to
date has shown that energy consumption is about as
low as that of the ERF250 in spite of the far better
efficiency.
Volker Neuber, Ettlinger’s managing director: “Users
of our new ERF350 melt filter very soon realize that
their investment pays for itself in minimal time
owing to the clearly superior performance. It’s a
highly efficient way for recycling plants to strengthen
their competitiveness in terms of costs and
performance in what is a fiercely contested market
constrained by price tags. Companies which process
large quantities will particularly profit from the new
technology. Compounders where PP is converted for
use in the automotive sector or manufacturers of, say,
LPDE packaging films, are only two examples here.”
