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.
