Abstract: Fan blades within a fan assembly are rotated in a first rotational direction, thereby generating airflow from above the fan blades downward past the fan blades. Airborne particles adhere to the surface of the fan blades as the air flows past. The fan direction is then reversed maintained at a relatively low rotational rate. A fluid is dispensed onto the hub of the fan blades. Due to the centripetal force of the spinning fan blades, the fluid is spread thin across the top surface of the fan blades and the liquid film washes the blade of the fan, removing particulates from the fan blade. The solution is pushed outward against the inner wall of the fan housing forming a fluid meniscus. The fan speed is increased to push the fluid meniscus into an annular reservoir. The collected fluid is then vacuumed and consolidated into the collection vessel.
