About Air Compressors

What is an Air Compressor?

Air compressors use stored pressurized air as a source of power. Most compressors have an electric or gas-run motor that helps to power the given compression method (pistons, rotors, etc.) Energy is stored as pressurized air in an air tank. The more air stored in the storage tank, the higher the pressure. When the air is used and the tank pressure gets too low, the motor will kick in and work to keep the pressure at desired levels.

Piston Air Compressor from C-Aire

Piston (Reciprocating) Air Compressors

Piston air compressors use one or more pistons to compress air and then pump the compressed air into a storage tank. Reciprocating pistons create air pressure by decreasing the size of the space holding the air. As the pistons move downward, outside air opens the inlet valve and fills the area above the piston. The piston then moves back up closing the inlet valve and opening the discharge valve. The compressed air goes into the tank where the pressure continues to rise.

Fire Protection Air Compressors

Fire protection air compressors are specifically engineered for dry pipe & pre-action fire sprinkler systems. In a dry sprinkler system, compressed air pressurizes the pipes that carry water to the sprinkler heads. When a fire causes one or more sprinkler heads to activate, the air escapes, and the dry pipe valve releases. This allows water to enter the pipe and flow through the open sprinklers onto the fire. These systems are designed for use in areas where the pipes are at risk of freezing, such as unheated buildings or outdoor areas.

Climate Control Air Compressors

Climate control air compressors are used in heating, ventilation, and air conditioning (HVAC) systems to control the temperature and humidity of the air in a building. The compressor provides air pressure to pneumatic actuators that open and close ventilation dampers, which allow air to flow into an area.

Rotary Screw Air Compressors

Rotary screw air compressors use two intermeshing helical rotors, or screws, to compress air. The rotors are driven by an electric motor and turn in opposite directions, trapping and compressing air between them as they rotate. Rotary screw compressors are known for their high efficiency and smooth operation and are often used in large-scale industrial operations with continuous compressed air requirements.
