Solder fume extraction

Mara Hofacker,

Mobile filter system for flexible use

ULT has introduced the new LRA 160.1 device variant, a mobile and flexible solution for removing small to medium quantities of soldering fumes. The extraction system has been incorporated into the design of the recently introduced new ULT 160.1 system generation.

In addition to improved device handling, the new filter system offers high filtration performance, low-noise operation and a very good price-performance ratio. Thanks to the long filter service life, users benefit from significant cost savings in the medium term. The mobile, robust and compact design of the LRA 160.1 enables flexible use at changing manual workstations. The device can also be connected to external soldering systems for automated operation via a D-Sub interface.

The easy-to-operate filter units offer installation options for one extraction arm (e.g. Alsident type) or two DN 50 hoses as standard.

Various solder alloys and fluxes are used during soldering. During the soldering process, large parts of the flux and a small proportion of the solder are vaporized - the resulting aerosols and particles can enter the production area. These airborne pollutants can cause serious illness among personnel. A particularly dangerous product here is aldehydes, which are formed from colophony-containing substances and can be carcinogenic in some cases.

In addition, gases are produced during heating from parts of the protective lacquer, adhesive or carrier materials of the assembly. These gases include sticky aerosols that settle in the soldering machines and on products and contaminate them. ULT 's extraction and filter systems are used to remove these air pollutants. The systems remove the smallest particles and vapors during manual soldering work as well as during automated and semi-automated soldering processes.
