Pneumatic Valves: What is a Pneumatic Sander? How Does It Differ from an Electric Sander?

Generally, sanders are required in any vehicle body repair or paint shop. Body repair techs and painters rely on sanders every day to achieve that perfect finish on their customers’ vehicles. Whether you’re preparing a car for painting or removing abrasive imperfections, having a quality sander will always make a difference between a dissatisfied and a delighted customer. The common type of sander typically used in body and paint shops is the random orbital or dual action sanders. This sander can be air-driven (pneumatic valves powered) or electric.

What is a pneumatic sander?

Pneumatic (air-driven) sanders are designed for industrial or professional use in the sanding of wood, vehicle body, metals, composites, and many others. Compared to electric sanders, pneumatic sanders are much lower-priced. To operate, pneumatic sanders require a compressed air installation that delivers a stable airflow. This sander is light and compact in size. Though they are noisier than their electric counterparts, they are less likely to heat up. 

Differences between pneumatic and electric sanders

As already mentioned above, electric sanders are more expensive than pneumatic ones. Electric sanders are also larger and heavier. This is because of the motor inside. Being air-driven, pneumatic sanders have no motor. Electric sanders are plug and use tools, while pneumatic sanders need an air compressor.

Advantages of pneumatic sanders

  • They are more resistant machines designed to withstand greater workloads.
  • Compact and lightweight – Allows for smooth and precise handling essential to perfect sanding. Time for finishing is shorter, and the worker gets less tired. 
  • They generate safer work environments because of the absence of electrical short circuits, shocks, and fire danger hazards, especially in work areas where varnish and other chemicals are present. They are even the safest option for the treatment of hazardous materials.
  • The design is simple, with fewer moving parts, implying lower costs in repairs.
  • They give off less heat, meaning greater comfort for the user, and can be used in extreme temperature conditions without affecting performance.
  • Can be used in any demanding environment, even without the presence of electricity.
  • Has a longer lifespan, so, therefore, it is the more profitable option.
