Suction Blasting Cabinet

A suction blasting cabinet is a type of sand blasting cabinet that uses negative pressure to draw abrasive media into a Sand blasting nozzle, where it is propelled onto a workpiece. The suction blasting process involves using a suction gun, which is connected to the cabinet by a hose. The gun draws the abrasive media into the gun through a venturi effect created by compressed air.

Suction blasting cabinets are commonly used for smaller applications, such as surface preparation of parts, cleaning and deburring, and etching. They are also ideal for use with lighter abrasive media such as glass bead, plastic, or walnut shells.

Suction Sand Blaster Cabinet

Suction Sand blaster cabinet works by sucking media from a hopper using the venture principle. The air jet is half the diameter of the nozzle, and as the air stream passes through both, a low pressure is created, sucking the media from the hopper into the air stream. The media acceleration distance is quite small (about 4 to 14" from the nozzle to the workpiece). The suction systems function properly and can blast continually as long as there are blasting media in the sand blasting hopper.

Suction Sand blaster systems do not deliver media well at low air pressures (5 to 25 psi), and the length of the suction feed pipe is limited. Suction blasting cannot transfer very heavy blasting (bigger steel media) into the air stream. Most industrial blast cabinets are suction systems that perform effectively with a wide range of media.

Suction Blasting Cabinet Working

The operation of a suction blasting cabinet is relatively straightforward. Here is a general overview of how it works:

• The operator places the workpiece to be blasted inside the cabinet.
• The operator selects the appropriate abrasive media for the job and fills the hopper with the media.
• The operator connects the suction gun to the sand blasting hose and turns on the compressed air supply.
• The operator pulls the trigger on the suction gun, creating negative pressure that draws the abrasive media into the gun.
• The operator aims the nozzle at the workpiece and pulls the trigger to release the abrasive media.
• The operator moves the nozzle back and forth over the workpiece, directing the flow of abrasive media to achieve the desired finish.
• Once the blasting operation is complete, the operator turns off the compressed air supply and removes the workpiece from the cabinet.

Suction Blasting Cabinet Features

Some of the key features of suction blasting cabinets include:

• Simple operation: Suction blasting cabinets are easy to operate and require minimal training to use effectively.
• Low cost: Suction blasting cabinets are generally less expensive than other types of blasting cabinets, making them a cost-effective choice for small-scale applications.
• Versatility: Suction blasting cabinets can be used with a variety of abrasive media, allowing them to be used for a wide range of applications.
• Small footprint: A suction blasting cabinet is typically smaller in size than other types of sand blasting cabinet, making them ideal for use in smaller workspaces.
• Easy maintenance: Suction blasting cabinets require minimal maintenance, and the abrasive media can be easily replenished as needed.

Overall, suction blasting cabinets are a simple and effective way to perform sandblasting operations on small workpieces. They are a popular choice for hobbyists, small businesses, and industrial applications where larger blasting cabinets are not required.
