AWH dirt traps have been specically designed and manufactured for installation in piping systems with
the aim of tration liquid ow in trade and industrial applications (food industry, chemical industry,
pharmaceutical industry and minimum-germ processes).
Fluids intended to be handled include water, steam, mineral oil, foodstuffs, liquids used in chemical and
the pharmaceutical industries, which are subject to a hygiene standard.
2.2 Intended Use
WARNING
This dirt trap is exclusively intended for the purpose detailed above. Any use
other than that outlined above or any modication made to the dirt trap without
manufacturer‘s prior written authorization shall be considered „not intended“,
and the manufacturer shall not accept liability for any damage that may result
from such use or modication not intended. The risk involved shall be solely borne
by the operating company. The dirt trap must not be commissioned until it has
been ensured that all safety devices are functioning and that the installation into
which this strainer has been integrated is in conformity with the EU Guidelines.
