102 Hepa Filter System
Equipped with a high-efficiency drop-in HEPA filter individually certified to have
minimum. efficiency of 99.99% at.3 microns (based on 1EST-RP-CC007 particle
count test method). For further filtration, a polyester prefilter is located on the
bottom of the HEPA filter and is held firmly in place with Velcro fasteners.
Additionally, a dacron filter bag (dacron material sheds dust to maintain vacuum
efficiency) covers the entire spacer sleeve and HEPA filter for three-stage filtra-
tion. In addition our paper bag provides an extra filtering area and is used in trap-
ping and holding the bulk of any recovered material and can be easily disposed
(for dry use only).
