Vlp Series - Cartridge Filter Cleaning - MAGUIRE NOVATEC VL Series Instruction Manual

11.2- VLP Series - CARTRIDGE FILTER CLEANING:

VLP Series loaders are typically used for conveying free flowing powder materials. For this
task, they are equipped with higher capacity cartridge filters. The amount of dust within the
conveyed materials will determine the frequency of necessary manual filter cleaning.
NOTE: Although the blowback system of the loader will extend the operational life of the
filter media, it cannot be relied upon alone. Frequent checks of the filter accompanied by
thorough manual cleanings are required, in addition to cleanings during material changes to
prevent cross contamination.
CAUTION: Disconnect electrical power and compressed air supplies before any type of
loader maintenance.
The cartridge filter(s) may be removed for inspection and cleaning by unclamping the ring
clamp of the lid, directly below the motor. If necessary, unplug the control cable and
disconnect the air line. Carefully remove the motor lid and expose the cartridge filter
mounting plate directly below the lid. The cartridge filter mounting plate, with the cartridge
filter(s) installed below it may now be carefully removed for inspection and cleaning.

filter cartridge. Do not attempt to repair the media. Remember that the filter
protects the vacuum motor and holes or any kind of leakage through the filter can allow
material to pass into and through the motor, severely shortening the motor's life, possibly
creating a fire hazard and sending material dust into the air around the loader. In addition,
examine the sealing ring around the top of each filter cartridge. This seal provides the
vacuum seal between the cartridge filter and the filter mounting plate and must be fully
intact. Replace the cartridge if this seal is not perfect.
NOTE: Polyester filter cartridges, supplied as standard with all NOVATEC VLP loaders are
washable to extend their life. Use only clean water, sprayed at medium pressure through the
media from the inside out to remove dust and debris. The cartridge must be thoroughly
dried before being put back into service. A commercial drying device may be used, or the
cartridge can be thoroughly drained of water and water droplets and left to dry for no less
than 24 hours.
