Pulse-Bac® Technology
represents a quantum leap forward
in the vacuum
industry.
Our revolutionary design in vacuum filtration does what
no other vacuum can do; prevent filters from clogging during
operation. CDCLarue patented Pulse-Bac Technology internally flushes
filters clear of dust
and debris using only vacuum and ambient air. No
blowers, compressors, shakers or buttons to push, just turn it on;
automatically the Pulse-Bac does the rest.
Pulse-Bac
vacuums are designed with two or more filters per
machine, each filter has a valve located above it; this
valve
controls both ambient and vacuum air flow through the filter. When a
cleaning cycle begins to flush clear a filter, the valve on that
filter (A) will shut
off the vacuum and open the valve to
an ambient air inlet. The valve
on the remaining filters (B) and or
(C) remain open and allow vacuumed air to
be pulled through them.
The closing of the valve on filter (A) triggers ambient
air to be
pulled through the filter in reverse, flushing the filter clear of any dust or
debris
that has face the outside of filter (A). Reversed ambient air
is pulled through
filter (A) by the vacuum pressure coming from
filters (B) and or (C). This entire
process takes place in less than a second and is repeated on
each filter continually while the vacuum machine is
operating.
