Maintaining optimal particle levels is an important part of creating the right environment for respirator fit testing. That's where AeroFit's Particle Generation Management (PGM) comes in.

This patent-pending feature automatically activates and deactivates the provided particle generator at defined time intervals, helping maintain optimal conditions throughout the testing process.

With PGM, AeroFit takes an active role in managing the testing environment, so you can focus on the fit test itself.
