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.
Key Features & Benefits
- Mobile Operation with Internal Compressor
The ATM 228 has a built‑in brushless compressor, so it does not require an external compressed‑air supply. - Stable & Reproducible Aerosol Generation, Even at Low Production Rates
The device is designed to maintain consistent aerosol output & quality even when operating at low flows or low particle production. This is important for sensitive tests or small filter cross-sections. - Compliance with Multiple Standards
The ATM 228 meets many international & national standards, including VDI 3491‑2, VDI 4258‑1, ISO 14644‑3, DIN norms, etc. - Support for Various Aerosol Media
Can generate aerosols from pure liquids, solutions, and suspensions (DEHS, PAO, salt solutions, PSL, etc.). - Optional Battery Mode & Remote Control
There is an option for battery operation for true mobility, and a remote-control interface - Compact and Lightweight Design
- Low Power Consumption
Max. approx. 36 W; works on standard AC power (100‑240 V) or 12 V DC (for battery usage).
Typical Applications
- Cleanroom acceptance and qualification
Use in ISO-classified cleanrooms (per DIN ISO 14644 and VDI 2083) to perform acceptance testing and airflow validation. - Filter integrity and penetration testing
Ideal for HEPA/ULPA filter testing, leakage detection, and quality assurance in ventilation or containment systems.
By choosing Topas for aerosol generation with the ATM 228, operators gain a mobile, high-precision, and fully compliant solution that ensures reproducible aerosol output for validation and testing across diverse cleanroom and filter applications.
