![]() ![]() Types of Air Compressors.Īir compressors are categorized as either positive displacement or dynamic displacement, based on their internal mechanisms. Generally, the differences aren’t too severe: it all boils down to the way a compressor handles air displacement. There are different types of air compressors and each one has a different specialty. Some of the more popular options are nailers, impact wrenches, sanders, and paint sprayers. It’s similar to how a combustion engine works, using a crankshaft, piston, valve, head, and a connecting rod.įrom there, the pressurized air can be used to power a variety of tools. They’re powered by an engine that turns electrical energy into kinetic energy. Think of it as an open balloon: the compressed air can be used as energy as it’s released. Then, the air is forced through an opening in the tank, where pressure builds up. They’re good choices for continuous use in shops or to power multiple tools at once.Īir compressors work by forcing air into a container and pressurizing it. These compressors are usually heavy-duty, commercial models that can deliver a greater volume of air at higher pounds per square inch (PSI) levels. The first compresses the air and pushes it through a check valve to the second piston, which compresses it further and delivers it to the tank. As you use the stored air to power a tool, the compressor restarts to build the air pressure back up. Once the pressure reaches a specified level, the compressor stops running. An electric motor or gasoline engine drives a piston, which compresses air and forces it into a storage tank.Īs the piston forces more air in, the air pressure rises. Single-stage, piston-type air compressors are the most common models for home use and work well for many applications around the home or workshop.

An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. The compressed air, then, is held in the tank until called into use. When the tank’s pressure reaches its engineered upper limit, the air compressor shuts off. By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. An air compressor is a pneumatic device that converts power (using an electric motor, diesel, or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). ![]()
