Cleanroom particle capture systems and cleanroom workstations include a duct carrying a particle capture air stream. A fan and a particle filter are arranged at the first end of the duct with at least some of the particle capture air stream passing through the filter, wherein the particle capture airstream has a first air velocity at the filter. A blow off device provides a blow off airstream into the duct at a second end of the duct, with the blow off airstream having a second air velocity at the second end that is higher than the first air velocity. The duct has one or more intervening features to reduce the second air velocity such that it substantially matches the first air velocity when the blow off airstream reaches the filter.

A micro particle flow facilitator, includes: (a) a bourdon tube having a flexible duct capable of expanding and contracting in response to pulsations of a pressurized fluid, the duct being hollow, closed-ended and having an inlet port; and (b) a fluid pulsator for providing the pulsations of a pressurized fluid to the inlet port of the bourdon tube, the pulsator being in fluid-tight communication with the inlet port of the bourdon tube and having a fluid inlet port for connection to a source of pressurized fluid.

A portable air abrasion device has a dispensing chamber and a flow valve for controlling the flow rate from the dispensing chamber. The flow valve includes a fluid flow chamber for receiving granular materials exiting the dispensing chamber. The fluid flow chamber has a granular materials inlet port, a fluid flow inlet port for receiving the flow of a fluid to the fluid flow chamber and a fluidized granular material exit port for dispensing a fluidized mixture of the granular material away from the fluid flow chamber. The fluid flow chamber also has a flow regulator employing a lead screw to control the flow of fluidized granular material through the fluidized granular material exit port.
