Length Scand
Tech Cables are made in standard lengths from 5' to 99'. Our
most common are 16', 23' and 33'. Custom sizes are available and
since they are Made in the USA, they can be ordered and
shipped Nationwide within 48 hrs. Standard sizes can be shipped
over night/next day.
Weight
Cable
Weight is important for many reasons. Scand Tech’s
lighter cables are easier to use in almost all applications,
especially when you are on a ladder. Lighter cables and brush
attachment systems allow the brushes to spin up to center so a
12 brush in a 12
duct will reach the top of the duct.
If a brush system is too heavy the weight causes the brush
bristles to bend making a 12
brush miss the top of the duct anywhere from 1 inch to 4 inches.
Bi-directional
If a brush spins clockwise it will “hug” the right side of a
rectangle duct (say a 12
x 16). When it is reversed it will “hug” the left side giving
you complete cleaning. Some of the above systems use threaded
brushes. A threaded brush may "unscrew” when spun in the
opposite direction of the threads. If it is held on with a clip,
the clip may be knocked off if it hits a corner. Remember,
losing a brush 20 or 30 feet down the duct, costs labor to get
it back, if you can Scand Tech cables are
bi-directional and the brushes are locked on quickly with
the turn of screw.
Brush Sizes Scand
Tech has five (5) different styles of brushes; for normal
dirt in Round duct, Metal Mix for severe or
“caked” on dirt in round ducts, Whip Brushes for
rectangular ducts (whips into corners that round brushes will
NOT reach), Soft Poly brushes for flex duct and bag
duct, Steel for dust collectors and kitchen exhaust.
Sizes from 4 to 28
(every 2). Remember:
If ducts were only ONE size, one brush would
work! PS. Straps vs. brushes? In our test, the straps only hit
50-60 % of the surfaces.
Will Center This
is important. If a brush is spun by a portable drill and can not
lift the end of cable attachment and brush assembly, then the
brush will not reach the top of the duct. Yes, most of the dirt
is on the bottom but you are cleaning the entire system
(tops and sides), aren’t you? Some systems have to use
extra stiff brushes to keep the shape, only problem is that they
do not bend and clean the complete surface. The Scand Tech
Brush System is the lightest system available. All brushes
spin up to full size so when you are cleaning the duct with the
proper brush, you will be cleaning the entire Duct!
* Each
brush system was purchased at full retail pricing with available
brushes. All brushes were tested with the appropriate size brush
in the same appropriate size ducts. All brush systems were
tested with the same Dewalt 18V cordless drill on both high and
low settings.
