What To Consider When Choosing A Rotary Screw Compressor

If a rotary screw air compressor is an important piece of equipment you use, there is no room for mistakes. This is especially the case when you are upgrading or replacing your unit. You want to choose a new compressor that is going to be equipped to handle your needs. Here are just some of the factors you want to consider during the selection process.

Airflow

The airflow of the system relates to the rate at which air moves through. This is formally measured in cubic-feet-per-minute, or CFM. The most important thing to understand is that there is no right or wrong CFM. Your selection should instead be based on the type of projects you plan to perform. Sit down and analyze the types of functions you need the compressor to perform, along with their CFM requirements. Choose an option that can accommodate the highest airflow requirement.

Air Dryer And Filter Design

Ensure you are selecting a model that is equipped with an air dryer and filter. These systems play an important role in controlling moisture and keeping unwanted particles out of the compressor, both of which can cause significant damage. If the unit does not have these features installed, in order to protect the compressor, you will be forced to purchase them separately. Having them already included saves you both money and time.

Horsepower

You also want to look at the level of horsepower the system can deliver. Remember, the greater the horsepower of the engine, the greater the power of the compressor itself. Similar to airflow requirements, you need to assess your needs. While you don't want to select a machine that is under-equipped to handle your needs, you also don't want to choose a machine that is over-equipped as doing so will only cost you money.

Electrical Configuration

Lastly, review the electrical configuration of the unit. Generally, rotary screw air compressors come with a single or triple phase electrical configuration. Which setup is best for you depends on the electrical load you can support. If you aren't sure of this, it might be a good idea to speak with an electrician to prevent costly damage to the unit and your electrical system.

Make sure you are taking the time to choose your rotary screw air compressor wisely. If you have concerns about what options are most important for your needs, a professional can examine your needs and help you make the right selection. Don't hesitate to ask.
