ZeroSmog filter set Z4V, main filter + 10 pre-filters

Refresh your work area with fresh Weller filters. The HEPA particle filter and the granulate gas filters are combined so that they can be replaced together as a main filter unit. Over time, the HEPA filter becomes clogged and the gas medium becomes saturated and oxidized. The fine dust filter (pre-filter mat) is the preliminary stage of filtration and is typically replaced monthly, depending on the application. This filter set is a convenient way of replacing the main and pre-filters in an optimum ratio.

• Main filter: HEPA class H13 particle filter; broadband granulate gas adsorption medium consisting of 50% activated carbon, 50% potassium permanganate (KMnO4)
• Pre-filter: High degree of absorption through class F7 filter mat
• The filter set is compatible with Zero Smog EL, TL and 4V filtration units and offers an upgrade over the standard filter in terms of performance and versatility
