Industrial Vacuum Cleaner Terms
– A specification that rates the output
power of vacuum cleaners rather than their input power, as measured at
the vacuum cleaner inlet with air flow suction. This is also referred
to as “sucking power.”
– A characteristic of vacuum motors that are air-cooled
with a ventilator that is independent of the cleaning air. Usually found
in either tangential exhaust systems or peripheral systems.
– International
professional designation available through training and testing by the
Association of Energy Engineers (AEE).
– Family
of chemicals used as refrigerants, being tightly regulated and phased
out of production due to stratospheric ozone depletion potential. Examples:
R-11, R-12, R-113, R-114, R-115.
– A design
of a vacuum cleaner in which the filtering system cleans the dirt suction
airflow before it goes through the fan
or fans of the suction motor. This prevents damage to the fan that results
from material carried by a dirty-air system and usually creates considerably
more suction, particularly when a hose and attachments are used.
– Cyclonic systems that separate the dust particles
from the airflow by spinning the air with a separation chamber. The spinning
causes centrifugal force to move the dust particles outward while the
air exits from the inner part of the chamber; some cleaners utilize multiple
chambers and most cleaners add filters to increase the total system filtration
efficiency.
– A design of a vacuum cleaner that has the air
carrying the dirt passing through the fan of the suction motor into the
bag. Typically, this does not create as much suction with attachments;
it commonly creates more airflow when operating with big openings and
short airflow distances.
– A design of a vacuum cleaner in which the airflow,
which picks up the dirt, passes through the fan of the suction motor
before it is cleaned by the filtering system.
– A special type of vacuum cleaner hose that has
internal wires that carry electrical current to the power nozzle’s
motor. Typically, these hoses reinforce the hose, but not always like
crush resistant hoses.
– A kind of filter media consisting of very
fine synthetic fibers on which a static electric charge builds as air
passes through. The charge draws the smallest allergen and dust particles,
helping the filter retain them.
– The fan or impeller that creates the suction necessary for
the vacuum.
– The percentage of particles retained by
the primary filter as air passes through it. The efficiency increases
as the size of the particles increase.
– A filtering efficiency
specification whose purpose is to effectively remove radioactive dust
from plant exhausts without redistribution. This filter must be able
to capture 99.97% of all particles 0.3 mm (micrometers or microns) in
size or larger from the air that goes through it.
– A type of filter or paper bag that uses similar
construction or fibers to that used in a true HEPA filter. While being
a significant improvement over regular filters, the vacuum that uses
it may not have a completely sealed filtration system, so there is no
guarantee that the stringent HEPA specification will be met by it.
– A kind of filter that is able to capture micron
size particles at an extremely high efficiency rate.
– The exhausting of cleaned air through many
small openings on the vacuum motor perimeter.
– In relation to the airflow in a vacuum cleaner, the
opposition to a passage of air. This occurs in a variety of ways in a
vacuum cleaner system.
– This manufacturing process creates dust recovery
tanks along with other vacuum equipment. It is the molding of a flat
aluminum disc to make a deep container from one piece of metal without
soldering so that all parts made this way are free from air leaks and
ensure the highest vacuum strength.
– The exhausting of cleaned air through a single
exit on the side of the motor.
– A characteristic
of particular vacuum motors in which the cleaning air flows through the
casing to cool it.
– A filtering efficiency specification
for filters utilized in environments that require the maximum degree
of clean air, like pharmaceutical labs. Specifically, these filters must
retain particles 0.12 mm or larger with the efficiency rating of 99.999%;
the testing and marking of certified ULPA filters ensures that these
filters are attaining the ULPA specification.
– The speed of air at any given point
in the vacuum cleaner system. It is the force of the air that collects
the dirt and moves it into the bag or dirt receptacle.
– In terms of vacuum cleaners, a measure of the power
of the vacuum created by the suction motor. This is essentially a measurement
of how high water is lifted by a vacuum hose attached to a tube placed
in water.
