Air Compressor

How to choose the best air compressor for my workshop?

The use of one or another type of air compressor will depend on the needs of the installation in terms of flow and pressure of the compressed air, it is also important to know the field of application of each type of compressor, to choose the most appropriate.

What kind of air compressor to choose:

Continuous use: workshop screw compressor Screw compressor
In the opposite case: piston compressor for workshop Piston compressor

The requirements of flow and compressed air pressure lead to choosing the power of the compressor, since each compressor is capable of guaranteeing a flow rate and a certain pressure with a different power.

To calculate the air flow you need to add the flow of every pneumatic tool to individual , which results in the maximum needs of air flow, and applying some coefficients to adapt the maximum theoretical consumption to the reality of each workshop, because not all the equipment works simultaneously.

We should not choose only for the price since cheap air compressors can cost us more in the long run.

Example:

To perform the calculation of the compressed air flow it is necessary to establish an average flow rate for each of the pneumatic tools (for example, 300 l / min.), As well as how many people will use the tools at the same time .

To obtain the total amount, simply multiply the average consumption , ie 300 liters / minute, by the number of workshop workers (imagine that everyone is working at the same time). Finally, to the total obtained, we must apply a coefficient of simultaneity (being 1, to be connected all at the same time, so we will take a value always less than 1).

Total flow = 900 l/min

Once we have an approximate calculation of air consumption and pressure, we can determine the power of the compressor. The following table can guide you about the power of the air compressor; However, before deciding on one or the other, you can contact us and we will advise you.

What is a scroll air compressor?

The scroll compressor is a positive displacement compressor . It is not a well-known equipment, but it has a typical application in oil-free applications.

The spiral compressor has an orbital displacement. The compression is done by volume reduction. The compressor assembly consists of two spiral-shaped rotors; one of them is fixed in the housing and the other is mobile, driven by the motor. They are mounted with a phase shift of 180º, which allows smaller air chambers to be created in their movement.

Do you know what are the advantages of this type of compressor?

Best running

A screw compressor uses rotating elements smaller and better capacity, thus preventing vibration and friction cause the pistons and thus achieving greater mechanical efficiency.

Higher air output by HP

Thanks to their greater efficiency, the screw compressor produces more air by HP. Generally, a piston compressor produces 3 to 3.5 cubic feet minute / HP. A screw compressor produces cubic feet 4 to 5 minutes / HP., Exceeding the compressor piston 30%.

Major work period under load.

Because of increased heat in the compressor piston, the working period under load is 50% -60%, with a maximum of 80%. Screw compressors are designed to operate with a period of low work load of 100%, ie continuously.

Durability

This is thanks to their greater efficiency, functioning more chilled and better balance. The screw compressor has a longer life, generally twice the compressor piston.

Do you know what are the advantages of this type of compressor?

Long duration

The materials used in the manufacture of piston compressors must be of high quality and high resistance to friction and wear.

Variable compression capacity

Depending on the number of cylinders, the compressibility can increase or decrease, depending on the process needs.

Adaptable

Piston compressors can be adapted to the type of use and industrial process for which required.
