The autonomous PAG 1000 (Portable Aerosol Generator), newly developed by Palas®, offers maximum flexibility for the generation of droplet aerosols, for example from DEHS, especially also at low concentrations.
The generator is small and with a weight of only 5 kg quite handy; being battery-powered makes it independent and quickly ready for operation. The fact that no compressed air connection is required demonstrates its flexible application options even more. A battery charge is sufficient for one working day and if needed, the device also operates on mains operation.
Thanks to the changeover operation of the internal pump for aerosol generation, the PAG 1000 offers a wide range of settings for the concentration. The electrical control via the internal display permits the reproducible setting of the particle concentration. Sample applications for the PAG 1000 include testing of laminar flow boxes, clean room accaptence test, test of smoke detectors, HEPA/ ULPA filter testing, laboratory applications or flexible aerosol supplies on site.
