Air Compressors

• Air compressors are large machines that power portable pneumatic tools. Pneumatic systems usually operate at pressures between 80 and 100 psi (pounds per square inch). Air compressors are normally plugged into an electrical outlet, but some can be carted to locations where electricity is unavailable. Pneumatic tool air compressors can be noisy and create a loud work environment.
  
  

Hosing

• Portable pneumatic tools are hooked up to air compressors with specially designed hosing that can withstand high pressure. Improper or defective hosing in a pneumatic system creates a hazardous work environment. Portable pneumatic tools should be hooked up to air compressors with abrasion-resistant, crush-resistant hosing. Hosing should be regularly checked for cracks and excessive wear.
  
  

Comparisons

• Portable pneumatic tools are usually lighter than electric power tools because they do not require a motor within the tool itself. Many pneumatic power tools are cheaper than comparable electric power tools, though the air compressors and special hosing can be expensive. Pneumatic tools generally require more regular maintenance than electric power tools but they are more durable, offer more power and deliver more torque.
  
  

Safety

• Ear protection is recommended when working with portable pneumatic tools and air compressors Operators should also wear safety goggles since debris may become airborne. Posting signs and erecting protective shields around workspaces where pneumatic tools are operating will help prevent injury to bystanders.
