To maintain and strengthen our leading position, we operate a large research and development department. Many of our developments are protected by patents and utility models.

By means of customised engineering we supervise all the individual subprocesses of a project – from outlining the requirements to the realisation and operation of the system.

We guarantee product and application related service worldwide and quick and reliable supply with BOLLFILTER GENUINE PARTS.
