Industrial Air Compressor Purchasing Step

There are several important factors to consider when we purchasing industrial air compressors.

From determining the required CFM, horsepower, pressure, and voltage, to deciding on the type of compressor, there are many considerations that can impact the efficiency and cost of your operation.

Step 1: Determine your required CFM, horsepower, pressure, and voltage

The first step in purchase the industrial air compressor is to determine your specific requirements for CFM, horsepower, pressure, and voltage.

CFM (cubic feet per minute) refers to the volume of air the compressor can deliver. What is CFM in compressor?

Horsepower and pressure refer to the power and force with which the air is delivered.

Voltage refers to the electrical requirements of the compressor and can vary depending on your location and power supply.

To determine your specific requirements, consider the size of your operation, the number of tools or machines that will require compressed air, and the frequency of use.

Choosing the industrial air compressor that can deliver the necessary volume and pressure to keep up with your operation, without wasting energy or incurring unnecessary costs.

Step 2: Determine the type of compressor you need

 Once you have determined your requirements for CFM, horsepower, pressure, and voltage, it’s time to consider the type of compressor that will best meet your needs. There are several different types of compressors to choose from, each with their own advantages and disadvantages.

2.1 Reciprocating, centrifugal, or rotary screw compressor?

Reciprocating compressors are typically smaller and more affordable, making them a good choice for small businesses or workshops. They work by using a piston to compress air, which is then stored in a tank.

Centrifugal compressors are used for high-volume applications, such as in power plants and factories.

Rotary screw compressors are a popular choice for many industrial applications. They use two rotating helical screws to compress air, resulting in higher volumes and smoother operation. Rotary screw compressors are ideal for medium to large operations that require continuous compressed air.

When selecting a compressor, consider the size and type of operation, as well as the specific demands of your equipment.

2.2 Fixed speed or variable speed compressor?

Fixed-speed compressors run at a constant speed, providing a steady supply of compressed air. These compressors are typically less expensive but less efficient than variable-speed compressors.

Variable-speed compressors adjust their speed based on the demand for compressed air. They are more expensive but more efficient, as they can reduce energy usage during times of lower demand.

2.3 Oil-lubricated or oil-free compressor?

Lubricated compressors use oil to cool and lubricate the internal components. They are typically less expensive but require regular maintenance to check and change the oil.

Oil-free compressors use special coatings or materials to lubricate the internal components, making them suitable for applications where oil contamination is a concern. They are more expensive but require less maintenance.

Oil-free compressors are best suited for operations that require a clean, oil-free air supply, such as the food or medical industry.

Step 3: Consider your budget and costs

When purchasing industrial air compressor, it’s important to consider both the upfront purchase cost and the ongoing operational costs. Here are some factors to consider:

3.1 Purchase cost

Reciprocating compressors are typically the most affordable, followed by centrifugal compressors and rotary screw compressors.

However, when considering the total cost of ownership over the lifespan of the compressor, rotary screw compressors are often the most cost-effective option.

3.2 Operational costs

Variable speed compressors are typically more energy efficient than fixed speed compressors, which can result in significant cost savings over time.

While variable speed compressors may be more expensive to purchase, they can often pay for themselves within a few years of operation.
