The manufactures in the electronic industry safeguard the environment and the RoHS directive eliminates lead in electronic products.
Lead-free soldering demands new technology, more flux and a higher temperature of the tools. An increased temperature will give up to 10 times higher reactivity in the chemicals. Higher reactivity will create faster and more powerful reactions in the active chemicals (flux), which will create more particles and new health risks.
Lead-free soldering gives up to 250 % more particles in the size 0.5-1.0 micrometer, the particle size with the highest risk to develop occupational asthma.
In lead-free soldering applications is it therefore of utmost importance to use a pre-filter to catch the bigger amount of the particles and increase the lifetime of the main filter.
A pre-filter for the high airflow systems MG 75, 95 and 100. The pre filter is mounted on the filter system. The filter media is of a “bag” type model with a high separation degree.
