How to choose the right screw air compressor for your factory

DEHAHA High Pressure Screw Air Compressor for Fiber Laser Cutting Application

Choosing the right screw air compressor for your factory involves considering a few key factors, including your air requirements, the type of applications, energy efficiency, and maintenance. Here’s a step-by-step guide on how to make an informed decision:


1. Identify Your Air Requirements:

This is perhaps the most important factor. Understand the quantity of compressed air required by your operations (measured in CFM, or cubic feet per minute) and the pressure required (measured in PSI, or pounds per square inch). You should choose a compressor that can generate enough air to meet these requirements.

Dehaha Compressor Company reminds you that when you need to purchase an air compressor, you need to confirm the air requirements of your environment.

2. Type of Applications:

Depending on your applications, you may need a different type of screw air compressor. For instance, oil-injected rotary screw compressors are generally used in industrial applications that require a continuous flow of air, while oil-free rotary screw compressors are required for applications where oil contamination must be avoided, such as food and beverage or pharmaceutical industries.

3. Energy Efficiency:

Compressors can consume a lot of power, so consider the energy efficiency of different models. Newer models often have better energy-saving technologies. Variable speed drive (VSD) compressors can adjust their output to match demand, saving energy during periods of lower usage.

4. Size and Installation:

Consider the space you have available for installing the compressor and whether you will need a stationary or portable unit. Keep in mind that you also need enough space for maintenance operations and adequate ventilation.


5. Maintenance and Reliability:

Regular maintenance is essential for the longevity of a screw air compressor. Consider the maintenance requirements, ease of obtaining replacement parts, and reliability record of the various models and manufacturers.


6. Noise Levels:

Some screw air compressors can generate significant noise which could potentially disrupt your operations or require additional investments in noise abatement strategies.


7. Cost:

Last but not least, consider the initial purchase price, installation costs, and operating costs (energy and maintenance) over the expected life of the compressor. Remember that the cheapest model might not be the most cost-effective in the long term.


Before making your final decision, you should consult with an air compressor specialist or sales representative. They can offer advice tailored to your specific needs, based on their expertise and experience in the industry.

Scroll compression principle Compressor sucks air through air inlet located at outer scroll.Compression chamber goes smaller with rotary movement and trapped air is compressed.Compression chamber becomes minimum volume at the center of the scroll and air is pumped out through air outlet located at the center of scroll.These, suction, compression & discharging, process is repeated continuously. Long maintenance cycle with long life consumable parts. Compressor head replacement at every 10,000 hours or 4 years whichever comes earlier. Scroll oil free screw air compressor, 100% oil free for food industry, dental and medical industry.
