Recommandations pour l'installation de filtres en Y

The location of mesh filters in engineering system diagrams is regulated by regulatory documents and installation instructions for pipeline fittings that require protection from mechanical inclusions in the working environment.

A mechanical filter is installed:

• Before electric and gas boilers and water heaters.
• Before control valves of heat flow regulators.
• Before pressure regulators and differential pressure regulators of any design.
• Before plate heat exchangers and some types of shell and tube heat exchangers.
• Before mechanical flow meters, some types of ultrasonic and electromagnetic flow meters.
• Before circulating and booster pumps, with the installation of a mesh filter being particularly important before pumps with wet rotors.

A mesh filter may not be installed if another filter is already installed on this pipeline within 10 meters.
