Types of Portable Sand Blasting Machines

1. Siphon Feed Sandblasters
   A siphon feed portable sand blasting machine uses suction to draw abrasive media from a hopper or container. Compressed air is used to propel the media through the nozzle, which creates a vacuum that pulls the material into the airflow. While siphon feed machines are typically more affordable, they may not offer the same cleaning speed or power as pressure-feed models.
2. Pressure Feed Sandblasters
   In a pressure-feed portable sand blasting machine, the abrasive media is stored under pressure in a sealed tank. The compressed air forces the abrasive material through the nozzle with greater velocity, providing a more efficient and powerful cleaning process. Pressure-feed machines are often used for heavy-duty applications where faster cleaning is required.
3. Wet Sand Blasters
   Wet sandblasters combine water and abrasive media to create a slurry that is used for cleaning surfaces. The inclusion of water reduces airborne dust, making them ideal for environments where minimizing dust exposure is important. Wet sandblasting is also gentler on surfaces compared to dry sandblasting, making it suitable for cleaning delicate materials.
