Sebo Exhaust Filter - S-Class (insert) for 300 and 350 Mechanical
The SEBO 50170ER S-Class exhaust filter was made to fit the 300 and 350 Sebo vacuum machines. It is recommended that you change this filter every 6 - 12 months on your vacuum machine.
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.
