How To Choose The Right Capacity And Pressure For Your New Rotary Screw Air Compressor in GA

It is very important to choose an air compressor that can supply you with enough CFM ( Cubic Feet per Minute ) of compressed air, at the right pressure. Unfortunately, most people don’t know exactly what they need, and end up buying a too large or too small rotary screw air compressor in GA. We’re here to help.

If you buy a rotary screw compressor, it is usually for one of the following reasons.

1. This is your first air compressor.
2. It’s a replacement for an old rotary screw compressor
3. You now have a reciprocating compressor, but need more capacity.
4. You already have a rotary screw compressor, but need more capacity.

For each of the above cases, here is how to easily determine the right pressure and capacity for you.

1. This is your first air compressor. Review the manuals or spec sheets of your pneumatic equipment. It should indicate the pressure at which the equipment operates and the amount of air ( cfm ) it requires. The part that needs the highest pressure dictates the required pressure. Add 1.5 bar to the maximum required pressure to account for pressure drop and load-unload the differential of your air compressor.

Now, add up the air consumption of all your battery straps tape collection equipment. This is the capacity ( cfm ) of your air compressor. It’s a good idea to buy a larger air compressor, but not too big. Rotary screw air compressors in GA don’t like standing still. Keep in mind that some equipment states the average consumption, while other equipment states the peak consumption.

2. it’s a replacement for an old rotary screw compressor. Review the current pressure and capacity of your old compressor. If your old compressor was adequate, buy a new compressor of the same pressure and capacity. Take a moment to decide whether it is a good idea to buy a slightly larger compressor to account for future expansion of your business.

3. You now have a reciprocating compressor, but need more capacity. Verify the pressure at which your current compressor is set. Don’t look at the maximum pressure of your current reciprocating compressor, as this is often much higher than the pressure needed to operate your machinery.

If you want to replace the compressor, check the capacity of your current compressor to determine if you need a larger compressor than you have. How much larger depends on the tools/equipment you added that made your old compressor inadequate. Again, be sure to take into account the future expansion of your business when determining the right capacity.

If you want to add the screw compressor as an additional compressor, remember that it they stand still for a long time, it makes them old and rusty. Always make the rotary screw compressor your primary compressor and the reciprocating compressor your secondary/backup compressor as rotary screw air compressors are more energy efficient.

4. You already have a rotary screw air compressor in GA, but need more capacity. Many times we see people buy the same type or capacity of the compressor as the current one, which is a good idea. It allows you to easily use the two compressors alongside each other, and use one as the backup for the other. Another idea is to buy a larger compressor and use the old one only as an emergency backup.

You might consider getting a variable speed drive (VSD) compressor to take care of the compressed air need when your first compressor can’t keep up.
