The Bosch VF120H Pleated HEPA Filter pairs with the either the VAC090A or VAC140A dust extractor with auto filter cleaning to help move users toward compliancy with the OSHA respirable crystalline silica dust regulation. The VF120H captures 99.97% of particles 0.3 microns and larger, and when installed in a Bosch HEPA ready VAC series dust extractor, the filter/dust extractor unit has been independently tested to meet the EPA definition of a HEPA vacuum. This filter can be used for EPA lead-related Renovations Repair and Painting (RRP) rule compliant applications. The VH120H filter and dust extractor unit is a critical component in the end-to-end Bosch PRO+GUARDTM Protection System — along with the right tool, accessory, attachment, connections and respirator. The use of a fleece filter bag is highly recommended when using VF120H. The filter bag may help prevent the HEPA filter from being directly exposed to abrasive materials and sharp objects that can be collected during normal use of a dust extractor. The VH120H is for use in dry applications only.
