For over three decades, Palas has built filter test systems for filters and filter media or has upgraded existing test rigs with components such as aerosol generators (droplets, salts, and solids), aerosol spectrometers, dilution systems, discharger systems, and automation software.
In the field of room air filtration, more than 14 existing test rigs have already been upgraded and automated using Palas technology to satisfy our international customers.
Upgrading and automation of particle measurement, as offered by Palas with the GVT 3000 (General Ventilation Test System Upgrade), serves in quality assurance and the development of filters in EN 779, ASHRAE 52.2, and ISO 16980 test rigs. The upgrade consists of an aerosol spectrometer, incl. a laptop/PC and monitor, aerosol generators (optionally: discharge unit), a sampling system, as well as automation of the measurement process.
The Palas aerosol generators offer unrivaled consistency in particle concentration and size. This forms the basis for the excellent repeatability of test results using the Palas filter testing systems and test rig upgrades.
