Air compressor

Pneumatic tools are powered by air that's typically delivered from an air compressor. Air compressors work by forcing air into a container and pressurizing it. They then force air through an opening in the tank where pressure builds up. Just like an opening of a balloon; we can use compressed air as energy as it's released. The three most common air compressors are the reciprocating, rotary screw and centrifugal. However, a two-stage double-acting reciprocating compressor is the most energy-efficient air compressor. Because it compresses air in both downward and upward strokes, doubling the capacity of the cylinder. Air compressor power tools can range from an air impact wrench, air drill, air hammer or air ratchet wrench.

Here is a simple diagram of how air compressors work

 

Safety

• Do not use gas air compressors indoors.
• Perform a routine safety check before each use of your air compressor: Check hoses, ensure proper power supply, check the oil level, etc.
• Always wear eye protection such as safety goggles.
• Wear hearing protection when operating your air compressor.

When using tools such as Impact driver, Air ratchet, Dust off Gun and Air riveter, you must take extra safety precautions such as...

• Never wearing a tie, loose clothing or jewellery (Watch, rings, Etc)
• Tie long hair back or secure under a cap.
