The VKL series of dilution systems according to the ejector principle forms the basis for VDI guideline 3491 sheet 15.The welas® VKL dilution systems are a classic among dilution systems, as they have been successfully used throughout the world since 1984. They are characterized by a particularly long service life and easy operation.The VKL series of dilution systems deliver a temporally constant, representative dilution with the factors 10 and 100. They can easily be cascaded down to a dilution factor of 1:1,000,000.The function of the cascaded VKL systems can be quickly and clearly validated by the user on-site. Depending on the application area, the VKL systems can be configured pressure-resistant to 10 bar overpressure or made of stainless steel for aggressive aerosols.The VKL systems can be combined with all common particle counters, i.e. for suction volume flows from the VKL step of approx. 0.03 l/min to 50 l/min.
