Types of large industrial air compressors

Large industrial air compressors are the backbone of many factories, construction sites, farms, and other places that need a big and steady supply of compressed air. There are two main ways to divide large air compressors: by how they make the air (the compression process) and by how strong and fast they are (their capacity and power).

• By Compression Process:

• - Reciprocating Air Compressors: These use pistons and cylinders, like car engines, to squeeze air. They work in stages, drawing in then pushing out air in a back-and-forth motion. Big factories with diverse needs often choose them for their multi-purpose use. Some models are smaller for medium sizes, but larger units can tackle more demanding tasks. Advanced designs ensure effective performance while steady piston movement controls sound levels. On the contrary, older models might feel noisier, so checking specifications first could help avoid extra noise.

  - Rotary Screw Compressors: Instead of pistons, these have two twisting screws that constantly push air through. They are quieter and run all the time, making them perfect for big spaces needing a steady air supply. Their design means they are less likely to interrupt work with breaks. Their durability often results in a longer lifespan compared to other types of compressors. This provides users with greater value for investment over time. Count on these compressors to keep delivering compressed air consistently day after day.

• By Size and Power:

  Large compressors can produce a lot of air: measured in Cubic Feet per Minute (CFM), with the CFM numbers usually being above 20. They are also sturdy and powerful, using horsepower (HP) levels from 20 to 150 or even more, making them heavy-duty machines. Users should know the CFM and HP ratings of their compressors.

- Full-Load CFM: This is the amount of compressed air the compressor gives when it is working at its highest level. Compressors with higher Full-Load CFM can provide more air, which is great for driving bigger air tools and equipment that need a lot of air. So, factories that run advanced machines that require more air are advised to go for those with higher CFM ratings.

- Horsepower (HP): This shows how powerful the compressor motor is. Motors with higher HP can squeeze out more air. Big factories or construction projects that use the compressor all day should pick models with more horsepower to meet their heavy air needs.

Specifications and maintenance of large industrial air compressors

The specifications for large air compressors can vary depending on the type. Here are some standard specs corresponding to various models:

• Tank Size: It could vary between a few liters to several thousand liters. For example, a 10HP rotary screw compressor has a tank size of 1000 liters.
• Flow Rate: The flow rate, measured in Cubic Feet Per Minute (CFM), indicates the volume of compressed air produced. For large compressors, it could be 20 CFM to several thousands CFM. For example, a 1000 liters 10HP rotary screw air compressor may have a flow rate of 37.3 CFM.
• Power: Power indicates how much electricity it consumes to run. It could be 2HP, 5HP, 10HP, 20HP, or more. For example, a 20HP rotary screw air compressor runs on 20HP power.
• Operating Pressure: It shows the maximum pressure the compressor can achieve. A large industrial air compressor's operating pressure could range from 100 PSI to 175 PSI or higher.
• Voltage: It is the motor's operating voltage. It can be 230V for_single-phase or 380V for three-phase motors. A 20HP rotary screw air compressor has a motor voltage of 380V.
• Weight: A large air compressor can weigh anywhere between 1000 KGs and 4000 KGs or more. A heavy air compressor needs more than one person to move and often has wheels for easy transport.

Some necessary maintenance aspects of large air compressors are as follows:

• Regular inspections: Users should routinely inspect the air compressor for visible indications of wear and damage, such as loose components, leaking hoses and worn belts. They should also check the oil level in the pump to ensure it is within the recommended range and look for any unusual noises or vibrations while the machine runs.
• Tighten loose components: After a rotary air compressor has been in use for a while, some of its components may become less tight. Regularly checking and tightening these parts can prevent air leaks, stop the machine from breaking, and extend its lifetime. Users should often verify pipes, fittings, connectors, and clamps, ensuring they're correctly aligned and securely fastened.
• Replace damaged hoses: Large air compressors often have hoses connecting to pneumatic tools and other equipment. Over time, some of these hoses may get damaged, affecting the amount of air they transmit and possibly the quality of the compressed air. A damaged hose can cause air leaks, reduce the efficiency of the compressor, and even lead to injury. Therefore, users should check the hoses regularly and replace the damaged ones if they find any.
