Portable and powered by gasoline, the air compressor is a staple for a range of applications, like inflating tires and running air-conditioners. This all-purpose device is also ideal for running air tools.

Gasoline air compressors come in several varieties, ranging from the frequent piston compressors to the more uniquely designed rotary and diaphragm compressors. The piston type is the most popular and relies on a piston to squish air into the cylinder. Alternatively, rotary version uses a spinning shaft for compression purposes, while the diaphragm variety vocally employs a diaphragm to complete its task.

With a range of 30 to 60 gallons (113 to 227 liters) of compressed air capacity, most gasoline air compressor models are equipped with a tank either crafted out of steel or aluminum. This reservoir serves to securely house the compressed air, enabling a wide variety of applications.

Acting as the beating heart of a gasoline air compressor, the compressor pump draws in air and renders it compact, ready for storage within a tank until use is necessary. Generally made of cast iron or aluminum, this powerful component functions as an essential part of the system.

Located close to the air outlet, most gasoline air compressors are equipped with a regulator to take control of the pressure delivered to the tank. This device serves as an adjustment valve, calibrating and modifying the power of the air pushed into the vessel.

Beginning a gasoline air compressor can be done with either a switch, a key, or a tug of the cord. Ready to get to work, it will hum along for around half an hour before it needs another splash of fuel.

Motorized compressors are employed to power a variety of air-driven tools and accessories, from screwdrivers and impact guns to sanders and air conditioners. Additionally, they can be used to swiftly fill tires with air.
