Please see also "Can or S-Class Filtered Household Vacuums Safely Retain Anthrax?" for an answer to this important question. For more information, see our article on External Structure Materials & Durability or General Electric's articles on GE Plastics and Designing with LEXAN Resin. Dirty- Design A vacuumed and cleaned design in which the flow which picked up the dirt passes through the fan of the suction motor before it is cleaned by the filtering. The maximum permitted for UL Approval is 12 Amps.
This prevents residual dirt or moisture in the main flow from coming in contact with the armature, field, carbon brushes, etc. 546 to get inches of water lift. Micrometer (µm) A unit of measure equal to 1/1,000,000 meter (10-6 meter). This should not be confused with the phrase "down to" which may mean a mixture of particle sizes for the stated efficiency.
The other has to do with the ability of the filtering to clean the so a minimum amount of dirt and allergens is recirculated back into the home. See also Flow. While usually not producing as much suction for use with attachments, this design often will produce more flow when working with large openings and short flow distances. Electrified Hoses A special type of vacuumed and cleaned hose which has internal wires which carry the electrical current which runs the power nozzle's motor.
Filtering media opposes the flow since the must flow around its fibers. Beater Bar A long rigid bar or raised area on a revolving brush roll which pushes the carpet away from the roll, creating a rapid beating action. See also our article on Filtration Efficiency -, ULPA, etc. This type of motor can only be used in vacuuming cleaned devices which incorporate the "clean " design so that very little residual is present in the main flow.
Beater Bar A long rigid bar or raised area on a revolving brush roll which pushes the carpet away from the roll, creating a rapid beating action. Bakelite Bakelite is an important thermosetting resin made from phenol and formaldehyde which can be injection molded to make parts which are resistant to heat, chemicals and moisture. Inertia The tendency of matter to remain stationary if not moving or to keep moving in the same direction if not stationary. It is shaped so that it wraps around the core of the armature on two opposite sides.

The acronym is used primarilly in the USA whereas Europeans often refer to the same filter as an S-Class filter. 97% of all particles as small as 0. It incorporates a revolving brush roll similar to that used in the upright type of vacuumed and cleaned and an electric motor to drive it.

See also our article on Suction Motor Design & Operation. turbulence within a hose slightly opposes the flow.
Canister Type The type of vacuumed and cleaned that houses the suction motor and filtering in a somewhat square or rectangular container. Opposition to flow is even present within the suction motor and vacuumed and cleaned case since the makes a number of sharp turns as it passes through them. A vacuumed and cleaned's suction motor reduces the pressure in order to create flow. For examples of excellent, see our list of Ristenbatt Vacuum's Preferred Models.
