**How to Perform High-Efficiency Leak Detection Using the TDA-6D/4B Aerosol Generator**
The **TDA-6D/4B aerosol generator** is a versatile and advanced device designed for generating submicron particles in both compressed and non-compressed gas environments. This dual-purpose system allows users to switch between modes seamlessly, making it ideal for a wide range of applications.
The **Laskin nozzle** is a key component of this generator, capable of producing fine particles within an airflow range of **50 to 5,000 cubic feet per minute (CFM)**. It can generate suspended particle concentrations ranging from **10 to 100 micrograms per liter**, depending on the setup. The system is built with durable **stainless steel construction**, featuring large fill ports and independent control over pressure and nozzle settings.
The **TDA-6D/4B** includes a **3-inch clean connector output**, and an optional adapter allows integration into positive pressure systems. Whether you're testing small cleanrooms, biosafety cabinets, or HEPA filter units, this device is designed to meet your specific needs.
This model is particularly recommended for systems operating at **5,000 CFM or less**, such as workstations, vacuum filtration units, and portable clean air systems. It is especially useful when **clean compressed air is not available**.
