Optional HEPA filter for W-3 Filtercart, with BGIA approval, class H 13 (Hepa 13 = 99.95 % of all suspended particles are filtered)
HEPA filters remove suspended particles from the air. HEPA stands for High Efficiency Particulate Airfilter
The filter consists of a close-meshed fibre net that retains particles of different sizes
The replacement of the filter depends on the intensity of use, therefore a service life cannot be predicted. If suction power is lost for example, a filter should be replaced
