Weller Tools, the world’s top brand in hand soldering solutions, offers a spare main filter for Zero Smog 4V to provide continuous clean air for the workplace.
Ideal for soldering, laser and gluing applications, the main filter consists of a HEPA class H13 particle filter and a granular medium. Contains 2.2 kg of granular medium composed of 50 percent activated carbon, 50 percent KMnO4 (potassium permanganate). This 50/50 blended medium is very flexible and is efficient with many more gases than just activated carbon.
The spare filter includes a small silicone hose and connector. This is used by Zero Smog 4V to measure the differential pressure through the filter to show when the filter is full.
The filter also fits the Zero Smog EL and TL filter units as an upgrade to the standard filters found in these devices.
The life of the main filter is extended by using it together with pre-filters. Pre-filters and the main filter can also be purchased as a convenience kit and at a reduced price (part number FT91000042).
