the basic versionInline Filter ILF
The separated solids collect in the filter tube and are discharged by hand. If the filter insert clogs, the filter can be backflushed.
Inline Filters ILF and ILF-V
Inline filters for hygienic and sterile process lines: a tubular filter surface separates the solids from the liquid. On the ILF they are discharged by hand, on the

Overview
Separating solids. In the line.
The filter sits directly in the pipeline and allows a high flow rate with low pressure loss in continuous operation. The simple, robust design makes filter changes, inspection and maintenance easy and safe.
- For gases and liquids
- Sterile design, static seals only
- Filter insert as perforated tube, slot tube or mesh
- Can be backflushed, on the
ILF-V inline through the sterile valve - CIP and SIP capable up to 160 °C
- Connections

Versions
Emptied by hand or flushed inline.
with attached sterile valveInline Filter with Valve ILF-V
The solids are discharged automatically through the sterile valve. If the filter insert clogs, the filter is backflushed inline. The housing stays closed.
