How to choose the best compressed air compressor

//How to choose the best compressed air compressor

How to choose the best compressed air compressor? That is why we must be clear that the use of pneumatic equipment rather than electric compressors is becoming more and more common in workshops processing natural stone and agglomerates. Both for performance, durability and reliability of the tool, as well as for safety, as it avoids the risk of electrocution in contact with water.

The quality of the air supplied directly affects the performance of the machine. And therefore the final finish resulting from its use.

Although in our sector, air compressors are largely intended to supply air to portable pneumatic tools. We have to take into account current and future needs when choosing and dimensioning our compressed air installation.

Traditionally, the piston compressor has been the most popular choice. This is due to its price for low air demand and lower air quality. However, today’s high quality pneumatic equipment such as the Alpha® pneumatic tool for which MASER is the exclusive distributor for Europe. These pneumatic tools of the American brand require a constant and dry air flow. This will guarantee the correct functioning of the equipment, thus ensuring the best final finish, making it necessary to choose a screw compressor with a built-in dryer.

SCREW COMPRESSOR VS. PISTON COMPRESSOR

But before we go on, let’s look at the advantages of the screw compressor over the piston compressor:

Air produced: 95% of the air sucked in versus 75% of the air sucked out, resulting in energy savings.

Idling: In screw compressors we can regulate the idling time (compressor operation without air production).  This is in contrast to the start-stop system of piston compressors, resulting in energy savings.

Nivel sonoro: 62-70 dB(A) frente 85-90 dB(A)

Duty cycle: 100% on load vs. 50-60%. The piston compressor limits the running time due to its need to rest for cooling. Compared to the continuous operation of the screw compressor due to its oil cooling.

Final air temperature: 20°C + ambient temp. vs. 75°C + ambient temp. which helps in this case to avoid excessive water condensation.

Wear: continuous friction of pistons, cylinders, rings and valves is a bad thing. It causes wear and tear, resulting in the piston compressor delivering less air in the long run with the same energy consumption. Screw compressors, as their blades do not have friction, there is no wear and tear and they always produce the same air.

COMPONENT INSTALLATION AND SIZING

As important as the choice of compressor type. It is also the correct installation of all components. Such as is the correct sizing of these.

We can choose to purchase a compact unit that integrates the screw, the boiler and the dryer in the same space:

 

Power ratings from 3hp to 30hp.

From 8 to 13 bar pressure.

Up to 3.000 lts/min of air delivered.

60 to 70 dB(A) maximum.

Pre-installed and pre-configured: plug, plug and play.

Compact: minimum footprint.

Easy maintenance.

 

Or we can choose to make an installation tailored to our needs. Depending on the air flow rates required at any given time, the number of operators who can work simultaneously, etc…

In this case, the traditional compressed air installation will be as follows and in this order:

FLECHA a, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granito

8 to 13 bar pressure compressor

FLECHA b, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granito

Tank capacity from 100 to 3,000 litres.

FLECHA c, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granito

FLECHA A, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granitoAir Filter.

FLECHA d, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granito

Dryer.

FLECHA e, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granito

Acceptance Filter.

FLECHA f, Maquinaria de obra, maser, maquinaria para piedra, marmol, piedra, granito

Regulator, Assembly, Couplers, etc…

Although there is a tendency to dispense with the dryer in order to reduce the investment. Pneumatic equipment must work with dry air, avoiding sending water, no matter how little, to the tools. In the long run, they will suffer from rust and/or corrosion problems, calcareous residues and others, which will shorten the useful life of the equipment. In addition, these will cause stoppages in your production with the consequent economic damage.

WHAT DOES MASER HAVE TO OFFER?

MASER has therefore added the widest range of compact compressors to its product catalogue. In other words, boiler, compressor and dryer in one piece. Or the possibility of acquiring each element separately to dimension the installation. Depending on your requirements, or to renovate and improve the existing installation.

In accordance with the air flow and pressure requirements of the Alpha® Professional Tools range of pneumatic tools distributed exclusively by MASER, we recommend that all professionals interested in acquiring them verify that their current compressor meets the minimum and essential requirements for correct operation and guaranteed finishes.

Especially for the Alpha® AIR834- polisher homologated by Cosentino and the Alpha® PSC-150 circular saw. These are our top products and we recommend the following models. Both will more than meet your technical requirements, all of them with built-in dryer:
