3.0 Description and Function - General
The 6-54 Dust Collector is normally attached to the surface preparation equipment with
50 feet of 5-inch diameter flexible exhaust hose. This dust collector is designed to be
able to fit through a 34-inch door opening and is mounted on a mobile chassis. During
actual operation, the surface preparation equipment cleans in a radial area around the
dust collector. Once an area is cleaned, the entire system is moved to an adjacent area
to repeat the process. During some applications, the dust collector may be positioned
in an adjacent room and connected with a longer hose. This procedure is usually done
on steel surfaces where less dust and contaminants are being removed. Blastrac does
not recommend using more than 50 feet of hose on concrete surfaces. Consult with
your Blastrac representative if you have a particular application that requires a longer
exhaust hose. The 6-54 Dust Collector is comprised of the following elements:

3.1 Description and Function - Filter Chamber
The central part of the dust collector is the filter chamber. Dust laden air enters the
chamber from the surface preparation equipment through the exhaust hose and into the
vent hose connection located at the bottom left from the control panel. The dirty air
passes through a plenum and flows through an array of four vertically mounted,
specially designed filter cartridges. Dust is captured on the surface of these filters
allowing clean air to pass to the clean air portion of the dust collector where it exhausts
to the open atmosphere.
The dust that was trapped on the external surface of the filters is periodically removed
by pulsing the filters with an internally supplied burst of compressed air. This
momentary pulse of air allows the dust to fall into a hopper at the bottom of the filter
chamber. Two filters are pulsed (in sequence) at a time, determined by a timer board
located in the control panel. This timer board is usually set to pulse a two filter bank
every ten seconds and allows the pressurized air reservoir to drop about 30 PSI during
