Dustless System
The Problem
Traditional floor sanding equipment uses a dust
bag to collect and "filter" the dust collected during the
sanding process. The bags are messy, difficult to empty, and
don't hold much material. This requires a technician to empty the
bag many times during a job. Because the bag is the only
source of filtration, the air flow through the bag and back into
the job space will always contain the smallest particles of
dust. The problem is compounded because as the bag fills
with material, it becomes a smaller "filter". Due to
increased back pressure from the partially full bag, the amount
of fine dust which is blown through the bag increases.
This also affects the ability of the technician to collect dust
from the floor and is often responsible for more dust being left
behind or becoming airborne as the bag fills.
Quite simply, dust bags attached to sanders
don't really work.
The Solution
Without a bag, the sander can function well. The back
pressure is eliminated and the dust pickup is very efficient.
However, something is still needed to collect and filter the
dust.
Bill's Floor Sanding has invested in the very
latest technology developed to solve the dust collection and
filtration problem, resulting in a virtually dust free
environment during and after the work project. The DUSTLESS
SYSTEM utilizes four distinct processes to accomplish this.
The mechanical process involves the use of a
cyclone, which is a centrifugal separator. The separator
uses gravity and airspeed to separate material from an air
stream.
The cyclone spins the air stream and drops the
dust into a dust cup. The air stream leaves the cyclone
and is again filtered through a high-efficiency cartridge
filter. The filter removes material to below 1 micron in
size. The dust that is in the bottom cup is removed via a vacuum
pump and compact hose. The dust is continually removed as
it is created and separated. The pump moves the material
into a 35 gallon drum containing a plastic bag.
The drum uses another small cyclone to drop the
dust into the plastic bag. The air stream continues through a
final filter that removes any fine dust from the air.
The problems stemming from the dust bags filling
up, leaking and passing fine dust through are now gone.
The system eliminates the need for plastic sheeting or masking
of room space. Filters stay cleaner longer because the cyclone
removes most of the dust before it reaches the filter. The
system holds a large volume of dust, therefore eliminating the
need to empty dust bags several times through the course of a
job. The plastic bag is self contained, and is discarded,
eliminating the need to contact the dust or any waste material.
The health of our customers and our employees is
ultimately more protected with the DUSTLESS SYSTEM.
Success Stories
I'm extremely pleased with the way the system
worked. Didn't have to put up any plastic at all. My wife
came home to take a look and she was thrilled with the fact that
there was no dust! She didn't look forward to doing months worth
of cleaning and changing the furnace filter every week while we
waited for the dust to go away. - Syracuse NY homeowner.
No one else is even close to having the
solution this system offers. I did a 500 sq ft re-sand and
finish the last couple of days. I sealed the floor last night,
and this morning walked over to the ebony grand piano in the
living room. It has a gloss finish, and when I ran my
finger across it, there was no dust. No dust! I couldn't
have claimed that was possible before, and while I am still
reticent about making wild claims about being dustless, I'm
getting closer.
