Zero-Smog Filter System
Weller Zero-Smog Systems have a three stage filter system for
removing fine particles, fumes and gases produced in assembly operations.
Filters to meet varying work place requirements are available.
The main areas where filtration is required are • Solder /flux fumes
Fine dust filter as per DIN 24185 / EN 779
Filter class
F5
F7
F9
HEPA filter DIN 24184, 24183 / EN 779 HEPA (High Efficiency Particulate Air) Filter
Filter class
H13
Filter process
1. Fine dust filter
For standard applications with little flux up to pollution
gases with high solids content. Weller offers the filter
classes F5, F7 and F9.
2. HEPA filter
Filters particles up to 0.3 µm. Weller offers HEPA
(High Efficiency Particulate Air)
filters of class H13, medium filtration efficiency 99.95 %.
3. Wide band gas filter
For cleaning harmful fumes and vapours. The Weller wide
band filter consists of 50 % active carbon and 50 % Pura-
tex. Harmful gases with a high molecular weight are clea-
ned by the active carbon. Puratex is suitable for absor-
bing gases of lower molecular weight. Because of its
composition, Puratex is able to convert a large number of
chemical pollutants by means of molecular modification
into non-polluting gases.
4. Gas filter (option)
The gas filter is used for extracting adhesive fumes and
solvents. Experience has shown that filtering suspended
particles is not so vital in this respect. The gas filter is fil-
led with 50 % active carbon and 50 % Puratex. The HEPA
H 13 is omitted.
