How does a Central Vacuum Work?
|
 |
- Clean air is drawn through the cooling air intake
port to keep the operating temperature of the BY-PASS MOTOR at optimum
performance level.
- A separate fan guard, sealed with a rubber sealing
ring, prevents objects and dust from entering the armature. This allows
only cool, clean air to pass by the armatures ensuring a longer life
for the motor.
- The spent cooling air circulates around the motor
and is directed centrifugal upward at approx. 60". Forced by the configuration
of the plastic cover on top of the power unit, the air then changes
its direction downwards through the circumferential opening of the motor
chamber and is expelled outwards. (See top view A and illustration B).
A sound baffle effect created by this change of direction reduces the
motor noise considerably.
- This method of venting the armature cooling air
affords the use of an optional motor intake muffler which reduces armature
noise to less than 50%.
- The directional flow intake speeds the airflow
radially along the inside of the separation chamber.
- Airflow is forced between the inside contour
of the separation chamber and the Dust Deflector Shield in a circular
motion, creating cyclonic action as the air spirals its way down through
the Cyclonic Separator Cone.
- The diminishing diameter of this separator cone
increases the velocity of the air, accelerating the centrifugal forces
that separate dust and debris from the airflow.
- This cyclonic action forces all heavy dust and
debris into the separation cone, where the venturi-like effect causes
all matter to be forced through the lower opening of the separation
cone into the dust canister where it is held down by sheer vacuum force.
- This process will ensure that the separated matter
will not be picked up again and reenter the separation cone and filter.
- SuperVac's unique double filtering system creates
an updraft for the returning air through the center of the separation
cone and through the filter.
- After passing through the filter the air enters
the fan chamber of the motor.
- Following the movement of the fan blades this
air is now directed through a directional exhaust vent, by-passing the
armature.
- Exhausted air, characteristically warm due to
the friction it has been subjected to along its path, vents any harmful
carcinogens and allergy causing particles outside your home.
- An optional exhaust muffler further reduces the
sound of the powerful motor without impeding the maximum airflow for
which the motor's has been specified.
