Labnics Aerosol Generator produces polydisperse challenge aerosols for filtration efficiency testing, with a flow range of 1,500–65,000 CFM and compressed inert gas operation. The photometer monitors aerosol concentration, while oil-circuit protection safeguards the supply system and heat exchange supports temperature control. Understanding the aerosol generator working principle helps assess aerosol concentration and filter performance. Manufactured for HEPA/ULPA filter testing and leak detection in cleanrooms and HVAC laboratories, this system supports air filtration performance assessment.
