Sand separators are used to remove sand, grit, and other fine solids from water. A sand separator removes 98% of particles 200 mesh (74 microns) and larger. A rule of thumb to determine if a sand separator removes material from a water source is to place some of the water containing the solids in a clear container. Shake the container and then let it sit and observe the material. If the material is large enough to settle out then a sand separator removes that material. The sand separator works using a centrifugal vortex. Water is drawn through tangential inlet slots into a separation chamber. Sand is centrifugally separated from the water and tossed to the perimeter of the chamber. Water free of sand is drawn to the center of the separator and up through the vortex outlet. Sand particles fall downward to the bottom of the separator where a flapper valve opens to let the sand out or a manual value is open to flush the sand out.

Sandblasting is the process of shaping, smoothing, and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies. Sandblasting can occur naturally, usually as a result of the particle blown by the wind causing eolian erosion, or artificially, using compressed air. Sandblasting can also be used to produce three dimensional signage.

Sander polisher is a multi-orbital action machine, which eliminates swirl marks and allows coarse grit paper to be used for high stock removal rates. On paint and fiberglass it leaves a perfect key for primers. The multi-orbital action reduces work surface heat generation, which is particularly important when sanding filters and paint. The tool can also be used for polishing because of its rotary gearing. It can also be connected to a centralized or freestanding dust collection system.

A sander is a power tool that used to smooth wood and automotive or wood finishes. It has a means to attach the sandpaper that does the work. Woodworking sanders are usually operated by electrical power while the ones used in auto-body repair work on compressed air.
