Topas ATM 228
Advaced Atomizer Aerosol Generator
The Topas ATM 228 is the most advanced atomizer aerosol generator at Topas, designed for mobile use with integrated compressor and optional battery operation. It excels at producing test‐ and calibration aerosols from pure liquids, solutions, or suspensions with high stability—even at very low particle production rates and low nozzle volume flows. It meets all requirements of VDI 3491 2 as well as relevant cleanroom and filter test standards.
Topas ATM 226
Atomizer Aerosol
Generator
The Topas ATM 226 is a robust and precision-engineered aerosol generator designed for use in cleanrooms, filter testing, and quality assurance environments. Crafted for mobility and ease of use, it integrates advanced atomization technology to deliver reproducible, well defined test aerosols for demanding applications such as cleanroom acceptance testing, HEPA/ULPA filter integrity checks, leakage detection, and calibration of aerosol measurement instruments.
Topas DIL 554
Aerosol Dilution
System
The Topas DIL 554 is a static aerosol dilution system engineered for cleanroom and filter test applications. Designed for mobile operation, it enables precise, reproducible dilution of high concentration aerosols down to 1:100 at a fixed flow rate of 28.3 L/min, making it ideal for upstream conditioning of particle measurement instruments.
Topas FCS 248
Photometer Calibration
System
The Topas FCS 248 is a precision-engineered photometer calibration system designed to provide stable, reproducible aerosols for the calibration of photometers, particle counters, and aerosol spectrometers. It is particularly suited for cleanroom environments, filter testing facilities, and laboratories requiring highly accurate and traceable aerosol generation for instrument validation.
