If both are used at the same time, some sand may be
Air-blast cabinets use one of two operating systems: pressure or suction. Pressure systems apply compressor power all the way from the media storage hopper to the nozzle outlet, resulting in faster work, more precise control at both high and low pressures and, in many applications, more efficient use of compressed air than is possible with suction systems.

an air lift (so named because it uses air to displace and lift the sand) to the top of the filter and is then passed counter current to a side stream of the clean water.
An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at the bottom of the discharge pipe which is immersed in the liquid.
An air lift pump, located at the center of the module, draws the media from the bottom of the filter up into the wash box. As the media is released into the wash box, it falls into the sand scrubber where the filtered solids are separated from the sand.

The main part of the Fluidbed Cleaning System is an insulated reactor containing sand particles. The sand is brought to a bubbling, 'fluidised' state by injecting air from the bottom. The reactor is directly heated using a 'flame-shield' at the bed surface in order to achieve temperatures around 450°C.
Apr 12, 2011· Air lift suction should take the sand out. Its how they dredge around ship wrecks to bring the small things to the surface. Use a large hose that will reach to the bottom of the well tape or fasten an air hose to the outside, with a hooked tube going into the larger hose at the bottom.
