Introduction (contd)
Both HDLV transfer pumps deliver the powder to the vibratory sieve, where
it is conditioned before delivery to the powder spray guns. Ultrasonic sieve
screens are available as an option.
The color change operation is partially automatic. At the start of a color
change, the lances are raised out of the powder source so it can be
removed from the feed center. Then, when the operator initiates the gun
purge, the lances are automatically lowered onto a purge manifold
assembly and clamped in place. High-pressure purge air is then pulsed
through the lances, in-line powder feed pumps, hoses, and guns to clean
them of powder. The reclaim and virgin HDLV transfer pumps are purged
manually when the operator is ready.
The Encore Powder Feed Center requires a remote air extraction system
that provides a constant airflow through the feed center enclosure,
preventing powder from escaping into the spray room. The typical
ColorMaxr 2 extraction system includes an afterfilter assembly consisting of
an exhaust fan, primary cartridge filters, pulse valves and controls, and final
filters, plus the ductwork to connect the afterfilter to the booth cyclone and
feed center. Afterfilters are available in 9000, 11250, and 15750 CFM
capacities.
A 10 inch duct with a transition section and a pneumatically-operated
damper is provided with the feed center.
