Introduction
(contd)
The color change operation is automatic and is initiated by the touch screen
control panel. During a color change, the VT hopper cycles through a
number of cleaning processes. High-pressure purge air is pulsed through
the powder feed pumps, hoses, and spray guns to clean them of powder.
This also cleans the sieve section and hopper itself, leaving minimal
cleaning for the operator. The reclaim and fresh powder transfer pumps can
be purged manually, as required.
The Spectrum VT feed center requires a remote air extraction system that
provides a constant airflow through the enclosure, preventing powder
escaping into the spray room. The typical extraction system has a dust
collector assembly consisting of an exhaust fan, primary cartridge filters,
pulse valves and controls, and final filters. A round duct connection is
provided at the top of the feed center enclosure.
