The diffusion mechanism is often a results of the collision with gas molecules via the smallest particles, Specifically Those people underneath 0.one µm in diameter, that are thereby impeded and delayed within their route through the filter; this actions is comparable to Brownian motion and raises the chance that a particle will probably be stopped by either of The 2 mechanisms above; it will become dominant at reduced air flow velocities.
Duct and fan HEPA filters models are employed with clean rooms and laboratories to eliminate hazardous airborne particles. They may be built to take out particles from recirculated air of turbulent and unidirectional ventilated clean rooms.
