Everything you need to know, before comparing different types of compressors

Each company or professional has its own need of compressed air, and sometimes they need a tailored solution, applying to a specific technology or different power ranges. Before evaluating different models, knowing the amount of compressed air needed by your tools and production machines is mandatory, as well as the the required air quality.

TYPES OF COMPRESSORS

Screw models

Screw technology is ideal for industries and professionals who need a great quantity of compressed air. The parameter to compare different models is the FAD (Free Air Delivery). You can choose between:

Piston models

Piston technology is suitable for discontinuous usage, which does not require a high airflow. The intaken air is a useful parameter to compare the different models. They are the ideal choice for hobbyists and professionals.

Oil-free models

For some applications, the high quality of the product requires an oil-free compressor, a technology that avoids any oil contamination (Class 0, according to ISO 8573-1:2010). They are available with scroll, piston, and water injection technologies as well as at a different power:

HOW TO SIZE A COMPRESSOR

When it comes to choosing the right compressor, the main principal aspects to consider in addition to the continuous/discontinuous usage are:

Maximum pressure (bar) depends on the tools and machines fueled by compressed air (for instance, car washing machines needs a 15 bar compressor).

Compressor power (HP) must be efficient to meet the air demand and the needed pressure.

In general, compressors are integrated with a compressed air tank, which lets you stock compressed air. The tanks’ size must be big enough to avoid the engine continuously switching on. Some models are equipped with a vertical tank, which is very useful in restricted spaces.

*Piston compressors’ data refers to the intake air; airflow (normally pointed as FAD) is lower

Maximum delivered air* (l/min o m3/h) is the quantity of air that the compressor can deliver in order to fuel pneumatic tools. To avoid oversizing your compressor and to keep the maximum safety margin, in general, users consider 30% of delivered airflow more than the estimated needs.
