S-class Pre-motor Microfilters –
S-class Pre-motor Microfilters (S =
“Schwebstoff” = airborne particles) are made from electrostatically charged
micro-fiber material, which attracts and captures dust particles from the airflow
of the vacuum before it passes over the motor to
cool it. Cooling the motor with super-clean air increases
motor life and reduces the possibility of
maintenance, even after many years of use. The S-class
Standard requires filters to absorb greater than
99.9% of particles down to 0.3 microns in diameter.
For comparison, 100 microns is the diameter of a
human hair. Their advantages are a relatively open
texture that allows smoother airflow for better suction
performance, a longer life expectancy, and they cost less than HEPA filters.
HEPA Pre-motor Microfilters (Optional) –
HEPA Pre-motor Microfilters
("High Efficiency Particulate Air") remove a minimum of 99.97% of all
airborne particulate matter down to 0.3 microns in diameter. Because these
filters use small grid-like structures to capture dust particles, dirt build-up
clogs the airflow pathway sooner than what is expected from S-class
microfilters. However, SEBO’s HEPA microfilters are sold along with four-layer
"Ultra-bags," which provide highly effective filtration before the airflow
goes through the HEPA microfilter, greatly increasing life expectancy and
reducing the potential of diminished air flow.
Exhaust Filters – Exhaust filters clean the air emitted by the vacuum motor.
