Dilution Systems » DC system

Dilution cascade with electrically operated pump to dilute highly concentrated aerosols with selectable dilution factors

Applications
  • Aerosol dilutions in filter media test systems, e.g. MFP 1000 HEPA and MFP Nano plus according to EN 1822 and ISO 29463
  • Aerosol dilutions in filter test systems, e.g. according to EN 779, ASHRAE 52.2 and ISO 16890
  • Aerosol dilution in clean rooms
  • Aerosol dilution in the operating room to determine the level of protection according to SWKI VA 105-1 and DIN 1946-4
  • Recovery tests according to ISO 14644-3

As with the VKL series deployed successfully worldwide, the DC series of dilution cascade uses the ejector principle. A compressed air supply is not necessary. The DC dilution system works with an external pump.

The dilution factors available for selection are 10, 100, 1,000 and 10,000, each with its own aerosol outlet. The DC 10000 can be used up to a particle size of < 5 µm.

The DC series, like the VKL series, can be combined with all common particle counters. On request, the DC series can also be operated with external compressed air.

This dilution system is used very successfully with filter media test rigs, including Palas® MFP 1000 HEPA and MFP Nano plus according to EN 1822 and ISO 29463, as a shiftable dilution cascade for both DEHS or salt aerosols.
