Hvac cleanroom design calculation explained. Traditionally designers have used an air velocity of 0 5 m s as the standard for cleanroom design however recent research has shown that velocities as low as 0 35m s are able to maintain the correct particle count within a room again dependant on the level of particles generated by people and processes. The above suggested air changes per hour are only a design rule of thumb.
