Siphon blast cabinets and pressure blast cabinets are the two main types of sandblasting cabinets that exist on the market. The two have some distinct differences in how they operate.A siphon/suction sandblasting cabinet is mostly used for light production and general cleaning of parts and objects. A siphon blaster works by using a suction gun with an air jet to pull blast media through a hose and deliver that media to a blast nozzle, where it is then propelled at high speed into the cabinet. Siphon sandblasting equipment is easier to set up, but it takes more blasting pressure to achieve maximum abrasive impact. Because of this, suction sandblasting cabinets will leave a less pronounced anchor pattern than a direct pressure cabinet using the same blast media.

A pressure sandblasting cabinet uses a pressurized vessel (like a pressure pot) filled with blast media, which forces the media  through a blast nozzle. Pressure sandblasting is significantly faster and more aggressive than suction sandblasting.

Sand blasting machine is equipment that uses pressure blasting techniques to clean rust, paint and other kinds of contamination from metallic parts. Main use of a sand blasting machine is to clean metals that are used in construction industry, ships, etc.

Portable sandblasting equipment is used worldwide in a variety of applications. Whether it’s offshore, marine, civil, general engineering and maintenance, or building and stone cleaning, Portable blasting equipment typically uses a pressure blasting technique; however, many hobbyist and DIYers use small, hand-help siphon and gravity blasters.
