PLG 1000

Aerosol generator for the defined atomization of oils and use on filter test rigs

Category:

Description

The PLG 1000 is a cold atomizer intended for use in air-conditioned rooms. If the room is unable to be air-conditioned, then a heatable version of the device should be used, e.g. PLG 2000 H.

Startup

The liquid to be dispersed is filled in the reservoir. The nozzle system developed by Palas® is immersed in the liquid. This nozzle system is based on the Laskin principle and guarantees extremely precise dosing constancy with uniform particle size. The mass flow is adjusted using the volume flow through the nozzle. The volume flow is controlled by a pressure regulator and a manometer on the device.

This nozzle system is based on the Laskin principle and guarantees extremely precise dosing constancy with uniform particle size (see Fig. 3).

The PLG 1000 generates mass flows of up to approx. 5 g/h max. (depending on the aerosol substance in use).
