Electric air compressors have several technical specifications that determine their performance and suitability for various types of use. Knowing these specifications is crucial to choosing the most suitable compressor for your needs.

Tank capacity is one of the key features of electric air compressors. A larger tank allows more compressed air to be stored, allowing you to work longer without having to switch the engine back on to recharge the air. This is particularly useful for applications requiring a continuous flow of compressed air such as painting or the use of pneumatic tools.

A large capacity means:

• Longer working sessions: Reduces the frequency of air recharge interruptions by increasing operational efficiency.
• Increased pressure stability: A large tank maintains a more stable pressure during use, improving the performance of pneumatic tools.
• Suitable for intensive applications: Ideal for jobs requiring continuous use of compressed air, such as sandblasting or powering industrial machinery.

The maximum pressure of an electric compressor is a crucial parameter that indicates the amount of pressure that the compressor can generate in the tank. Most standard air compressors reach a maximum pressure of 8 bar, while professional models can reach up to 10 bar.

The advantages of high maximum pressure are:

• More air available: It allows more air to be stored in the tank, increasing efficiency and the duration of work sessions. Each additional bar increases the amount of air stored in the tank by approximately 10%.
• Use of professional pneumatic tools: It allows the use of a wider range of tools that require high performance to operate correctly.
• Versatility: Makes the compressor suitable for different types of jobs from small housework to industrial applications.

As far as pressure ranges are concerned hobbyist and DIY compressors have a maximum pressure ranging from 0034 to 8 bar. These are sufficient for light operations such as inflation and cleaning. Professional and industrial compressors, on the other hand, operate in a range of 8-10 bar, offering superior performance for high pressure pneumatic tools.

Pumped intake air is one of the most important technical specifications of electric air compressors as it identifies the true air production capacity of the compressor. The higher this figure, the better and generally larger the compressor will be. This parameter may be less essential for the use of small equipment but becomes crucial for professional pneumatic tools that have a high air requirement.

The advantages of a high intake air capacity are:

• Increased operational efficiency: It allows pneumatic tools with high air demand to be supplied continuously and without interruption.
• Suitable for professional equipment: Essential for the use of equipment requiring large amounts of air such as sandblasters and wreckers.
• Increased productivity: Reduces downtime due to lack of compressed air and improves overall productivity.

The intake air capacity varies considerably between air compressor models, with values ranging from less than 150 to more than 600 litres per minute. An important technical fact is that in order to obtain the "air produced" figure, it is generally necessary to cut 15-20% off the intake air figure due to the natural dispersion that occurs between the intake air and the air actually available in the tank.

The rated power of an air compressor expressed in HP (horsepower) is an indicator of engine performance. A more powerful motor improves the overall performance of the compressor, allowing the pumping unit to be fed more efficiently and smoothly.

The compressor's power rating ranges from less than 1 HP to more than 5 HP. The size and power of the motor are normally proportional to the size of the pump and its air intake capacity, determining the overall performance of the compressor.

• Superior performance: A powerful motor supports a higher air intake capacity and higher pressures.
• Longer service life: Reduces stress on the engine during operation and extends engine service life.
• Suitable for intensive applications: Required for powering professional pneumatic tools and continuous industrial use.

The cylinder head RPM is a key indicator of the performance of an electric air compressor. Low header revolutions mean better compressed air performance at lower temperatures and less wear on the pump unit.

The advantages of low header revolutions are:

• Improved operational efficiency: Reduces compressor heating and improves overall efficiency.
• Less wear on the pump unit: Extends compressor service life through reduced mechanical wear.
• Compressed air at lower temperatures: Ideal for heat-sensitive pneumatic tools and longer compressor life.

Coaxial compressors with a pump directly connected to the motor operate at over 2400 RPM, while belt-driven compressors operate below 1650 RPM. A greater reduction in engine speed transmitted to the cylinder head ensures slower rotation, improving compressor service life and performance.

Electric air compressors can be equipped with two types of transmission: coaxial or belt-driven. The choice between these two systems significantly affects the performance, maintenance and intended use of the compressor.

Advantages of coaxial compressors

• Connection to tractor: Suitable for agricultural use and in environments without direct access to the power grid.

The side cooling manifold is a feature designed to reduce the temperature of the air leaving the pumping unit. This ensures compressed air at lower temperatures and less wear and tear on the compressor.

In other words, this component contributes to:

• Improved operational efficiency: Reduces compressor overheating by maintaining an optimal working temperature.
• Less compressor wear: Extends compressor service life by reducing the heat generated.
• Superior quality compressed air: Provides compressed air at lower temperatures, ideal for heat sensitive applications.

The side cooling manifold is particularly useful in intensive and professional applications where temperature management is crucial to maintain optimal performance and extend compressor life.

The type of pump used in an electric air compressor largely determines its performance and applicability. The pumps can be single-stage, two-stage axial 3-piston or piston pumps. Compressors with 3-piston axial pumps are suitable for small domestic jobs, while those with 2-stage pumps are ideal for industrial applications requiring high performance and reliability.

Choosing the right type of pump means more:

• Operational efficiency: Each pump type has a specific efficiency that can be optimised for particular applications.
• Compressor life: A suitable pump reduces wear and improves the durability of the compressor.

The noise level is another important factor, especially if the compressor is used indoors or in residential areas. Silenced compressors are designed to operate at lower noise levels, improving user comfort.

The maximum pressure expressed in bar determines the compressor's efficiency in handling pneumatic tools and specific applications. A pressure of 8 bar is sufficient for most hobby applications, while for professional and industrial applications a pressure of up to 10 bar is preferred. The air capacity measured in litres per minute indicates the amount of air that the compressor can produce. A high value is essential for high-demand pneumatic tools. The nominal power rating expressed in HP affects the overall compressor performance; more powerful motors ensure greater efficiency and durability.

The type of power supply must be chosen according to the availability of electricity at the place of use. The compressors can be powered by 230 volts single-phase electricity suitable for domestic use or 400 volts three-phase electricity required for professional and industrial use. There are also battery-operated or tractor-mounted models for specific uses. Cooling systems such as side cooling manifolds are crucial to maintain operational efficiency by reducing overheating and extending compressor service life.

Electric air compressor pumps can be single-stage, two-stage, axial 3-piston or piston pumps. Axial 3 piston pumps are suitable for small housework, offering a good compromise between cost and performance.
