How to choose air compressor suitable for the glass industry?

What You Need to Know Before Buying a Compressor

If you are planning to buy an air compressor, then it is obvious that you need to buy a quality compressor in order to achieve psychological expectation. There are several factors that you need to consider to help you choose the best compressor.

Below are some of the top things that you need to know before buying a compressor.

1.Horsepower

You need to determine the size of the air compressor and one of the best way to get the exact size is checking on the horsepower rating. However, some salesperson may exaggerate the ratings and it is important that you get the actual rating of the horsepower. You may consider checking on the amount of power consumed after running the compressor. Usually, a 5 HP motor will run on 24 amps on 220 voltages. If the ratings are overrated the motor could draw about 15 amp, 110 voltages. Simply find a way to ensure that the horsepower is accurately rated value.

2.Air tank size

The size of air tank may not be significant as it is only used in storing the compressed air. However, if you need to save some money, you may choose a smaller air compressor if compare with a larger tank. Also, remember this option is only possible if you use compressed air intermittently. The compressor will run in the same way, no matter bigger or smaller tank. The only difference is that the smaller tank may not be more efficient before starting and cooling compressed air period.

If you financial situation well, you may consider buying a smaller tank as it is more portable and efficient when rising up the pressure.

3. Air pressure

You also need to check the air pressure rating to ensure that you purchase a compressor which runs more efficiently. In most cases, the air pressures are rated about 90 PSI. With such a rating, the air compressor will run properly but you need to ensure the compressor has a higher shut-off pressure valve.

4. The CFM (Cubic Feet Per Minute)

If you need to purchase a high quality compressor, the key is ensure the volume of compressed air which produced by the compressor. The CFM rating is according to the size and speed of the compressor. As a efficient air tool, you may consider a 3 to 4 CFM for a 90 PSI compressor. The CFM ratings may be exaggerated like the horsepower ratings, so you should be careful to ensure the CFM ratings are correctly.

How Do Rotary Screw Air Compressors Work?

All compressors work using a mechanical element that physically reduces the volume air takes up, compressing it. In a rotary screw compressor, that mechanical component is a pair of screws. These two screws are meshed together and turn continuously. Air enters and is then compressed in the gap between the screw threads. Here’s how oil-flooded rotary screw air compressors work:

1. Air enters the compressor through the inlet valve.

2. Air then travels through the pressure control line and into the regulator valve. This process sets the air pressure for the system.

3. Both oil and air enter the compressor, where they combine into a mist. Air travels the length of the matching rotary screws and becomes compressed.

4. After exiting the compressor, the air and oil mist enters the primary oil separator tank. The tank uses centrifugal force to make the oil molecules come together, forming droplets that fall to the bottom of the tank. The oil can then be recycled into the air compressor for the next batch of air.

5. The air then enters a secondary separation filter, which further purifies the air and removes more of the oil.

6. The oil-free air then exits the system, into a reserve tank or the connected air tools or machinery.

7. The oil travels from the separator tank to an oil cooler. Next, it goes through a filter that removes any debris and is then returned to the air compressor.
