Air compressors can power a variety of tasks, from powering a car to operating a nail gun. If you want a handy experimental air compressor, you must first understand the relevant technical knowledge of the air compressor. Read on to make an informed choice.
Single-stage piston air compressors are commonly used domestic models and work well in many applications in the home or workshop. An electric motor or gasoline engine drives a piston, which compresses the air and forces it into a storage tank. As the piston forces more air in, the air pressure rises. Once the pressure reaches the specified level, the compressor stops. When you use the stored air to power the tool, the compressor restarts to establish air pressure.
The two-stage compressor has two pistons. The first compresses the air and pushes it through the check valve towards the second piston, which further compresses the air and delivers it to the storage tank. These compressors are usually heavy commercial models that can deliver more air at higher pound-per-square-inch (PSI) levels. They are ideal for continuous use in a store or to power multiple tools at once.
Stationary air compressors are large equipment designed to be placed in a shop or garage. These are high-powered models with large storage tanks that can be used without interruption for long periods of time. They usually have a vertical design, reducing the floor space required.
Portable air compressors have smaller air tanks, handles or wheels that allow you to easily move them to different work areas. Compared to fixed models, they are more compact and suitable for lightweight, fast applications such as spray guns and powering most types of nail guns. And there are several styles:
A flat flat air tank is installed at the bottom of the pancake compressor unit. The design adds stability and takes up less space than other styles.
The hot dog compressor has a horizontal design with a single cylindrical storage tank.
The double stack compressor has two horizontal cylindrical oil tanks. The stacked design increases air capacity without increasing the footprint required for the unit.
The unicycle compressor has two cylindrical fuel tanks with a wheel and handle for easy movement.
The inflator is the smallest compressor. The inflator does not have an air tank, so the motor must be continuously running to provide air. This type of compressor can inflate small floats, tires and sports equipment.
Electric compressors are common models. Compared to gasoline-powered models, they require less maintenance, operate quieter, and can be used in any dry area, as long as a power source is available. Electric compressors are suitable for working indoors. Many domestic compressors operate at a domestic current of 120 volts, but larger models may have different requirements. Portable electric compressors require suitable extension cords, which can limit mobility. Follow the manufacturer’s specifications for extension cords and refer to the power cord safety tips. Depending on the model, the inflator can be plugged into a 120 volt household socket or a 12 volt car accessory socket.
Gas-powered air compressors are ideal for outdoor work areas with limited or unavailable power. They usually have more horsepower than electric models, so they can produce a larger PSI.
Do not use the electric compressor in a humid place. Do not use gasoline-powered compressors indoors or in closed or unventilated places.
Air compressor specifications
The horsepower (HP) rating of the compressor indicates the power output of the engine or electric motor. Measured in PSI, higher horsepower produces more air pressure. A higher PSI means that the compressor can store more air in the fuel tank, allowing you to operate pneumatic tools longer. Cubic feet per minute (CFM) and standard cubic feet per minute (SCFM) describe the amount of air delivered by a compressor at a particular PSI level. The CFM value changes with PSI. When the PSI output is reduced, the CFM increases. Compressors with higher CFM ratings provide more air and are more suitable for heavier applications, such as operating pneumatic wrenches and frame nailers.
Compressor manufacturers evaluate tank sizes in gallons. Smaller tanks (approximately 4 gallons to 6 gallons) are sufficient for many projects, such as spray guns and nail guns or nail guns. Larger tanks can store more compressed air at higher pressures. They are suitable for larger tasks that require continuous airflow, such as automotive work and retrofit projects.
Horsepower represents the power output of the compressor, and the CFM rating of a particular PSI level determines which tool the compressor will use.
The power of electric tools is a key function of air compressors. Think about the tools you want to use now and the ones you might need in the future. Examples include:
Staple gun and stapler
Air Hammer / Chisel
Paint spraying machine
Rotary tools / grinding machines
Most pneumatic tools have specific requirements for air volume and pressure. The compressor must meet these requirements for the tool to function properly. When choosing an air compressor, consider the tools to power it. Determine which requires the highest CFM with the highest PSI. For safety, add 50% of the CFM to the required CFM and look for a compressor that meets the requirements. For example, if the tool requires 3 CFM at 90 PSI, choose a compressor that provides at least 4.5 CFM at 90 PSI.
Air compressor function
Understanding the available air compressor features can help you choose a model that can handle and simplify your work:
The oil-free pump reduces maintenance and does not mix oil into the compressed air.
Belt drive systems run quieter than direct drive systems.
Thermal protection stops the motor to prevent overload damage.
The adjustable exhaust allows you to direct the exhaust away from the work area.
Multiple connectors allow you to handle different tasks without having to connect and disconnect tools.
The included accessories and tools (such as hoses, nails and blow guns) add value to your investment. Please note that not all compressors are equipped with air hoses.
You can purchase auxiliary air tanks to increase air storage capacity.
The air hose must meet the specifications of the compressor and the tool you plan to use.
The car air compressor is suitable for inflating bicycle tires, car tires and sports balls. It inflates ordinary tires in 5 to 6 minutes. This is a built-in pressure gauge with compactness and low power consumption. Compressed air can also be used in automotive areas to provide power.
