DIL 556 Dilution System

DIL 556 Dilution System for static dilution (1:10) of aerosols at static air flow rate (2,83 L/min)

The DIL 556 Dilution System serves for the defined and reproducible reduction of particle concentrations in aerosols.

The main application of the DIL 556 dilution system is the verification of test aerosols for testing clean rooms. DIN EN ISO 14644-3 defines the necessity of appropriate dilution systems when using test aerosols for verification. In the applied principle that corresponds to the standard VDI 3491-15, particles are removed from the sample aerosol according to the specified dilution ratio. The particle size distribution remains unchanged.

Benefits

  • constant and reproducible aerosol dilution even under changing operation conditions
  • internal monitoring of the dilution ratio and visualisation
  • suitable for mobile operation (compressed air supply is not required)
  • long-term lifetime, minimum maintainance required
  • precice operation for both overpressure and underpressure
  • flow rate and dilution factor adjustable for customer requirements

Applications

From the aerosol flow to be diluted, a sample is passed through a thin capillary. The particle concentration of the capillary flow rate remains unchanged, whereas a HEPA filter removes nearly all particles from the bypassing flow rate. After the capillary and filter both flows are remixed. The dilution ratio results from the ratio between the two single flow rates.
