DC 10000

Dilution cascade with electrical operating pump

Still have questions?


The DC 10000 consists of four cascaded special dilution systems with a dilution factor of 1:10. The DC 10000 dilution cascade has one aerosol inlet and four aerosol outlets. Depending on which aerosol outlet is connected to the measuring device, the aerosol with the dilution factors 1:10, 1:100, 1:1,000, or 1:10,000 are diluted.

The DC 10000 can be operated with all standard optical particle counters (OPC) according to ISO 12501-4 or optical aerosol spectrometers (OAS) according to ISO 12501-1. The DC 10000 can be used up to a particle size of approx. 5 µm.

Dilution cascade with electrical operating pump

Fig. 1: Functional principle

Particle-free air with the volume flow VR circulates through an annular passage around the suction nozzle. Thus, according to Bernoulli, a volume flow VAn is generated in the suction nozzle.

The dilution factor VF is calculated according to the formula:

The DC 10000 needs no compressed air connection. So only an electrical power supply is necessary for operation.

Table 1: Technical characteristics of Palas® dilution systems


  • No compressed air connection; only electrical power supply 115 - 230 V, 50 - 60 Hz
  • Dilution factors 1:10, 1:100, 1:1,000, 1:10,000
  • The user can perform a simple functional test on-site
  • The dilution systems can be combined with all common particle counters
  • The dilution systems from Palas® are characterized unambiguously. This is documented with a calibration certificate for each individual device.
