    Gas Filter

    A device that retains dust particles conveyed by the gas and protects the elements in danger (burners, counters, boilers, pressure regulators, etc.) from rapid clogging.

    It consists of a filter cartridge made of washable synthetic material and can be entirely removed for full inspection, cleaning and/or replacement.

    This device is designed with special type O sealing ring, which is convenient to use, it can be used on town gas, natural gas, liquid petroleum gas and other non-aggressive gases.

    NSTALLATION REMARKS:

     

    1.All installation/maintenance must be carried out by professionally qualified person. 2.Please close the gas supply valve before installation.

    3.Gas filters are usually installed upstream of proprietary regulating and switching devices. After installation, the arrow direction on filter (3) must point to the using equipment and the filter should be installed anywhere that will not interfere with the normal operation of the equipment.

    4.Care should be taken during installation to avoid debris or metal waste entering the filter.

    5.  For threaded connection, check and make sure the pipe thread is not too long; If the thread is too long, it will damage the filter when screws are installed. The connection of pipes and fittings must match the connection thread of the filter.

    6.For flanged conncetion, check that the inlet and outlet butt flanges match each other. Avoid unnecessary mechanical pressure on the filter. At the same time, calculate the space needed to install the sealing ring. If the gap left after installing the sealing ring is too large, do not close the gap by tightening the filter.

    7.Check the gas after installation to ensure no leakage.

    MAINTENANCE

     

    Change the filter element if the difference between the up and downstream pressure exceeds 10 mbar. We recommend replacing it at least once a year anyways. To replace it, please follow the following procedure:

    -  Shut the gas inlet off by shutting the upstream valve off,

    -  Loosen the screws and remove the cover,

    -  Remove the filter element and clean it carefully or replace it with a new one

    -  Re-install the cover so that the guides inside

    the cover correspond with the filter element, and retighten the screws,

    -  Check that there is no cover leak.
