When selecting a suitable air compressor for your business, a few factors must be considered beyond the cost. The efficient functioning of material handling, spray painting, machine tools, and various other operations rely heavily on a reliable compressed air system.
Air experts often suggest the use of screw air compressors. These compressors offer high efficiency, continuous operation, low noise levels, a compact design, and exceptional reliability.
How Screw Air Compressors Work?
Screw air compressors are known for their efficiency, dependability, and ease of use. They employ the use of oil for cooling, sealing, and lubrication within the compressor. The core of a screw compressor comprises of two rotating elements known as rotors. These rotors feature interlocking helical grooves that progressively reduce the volume of air as it passes through the compression chamber.
As the rotors rotate, they draw in the surrounding air, trapping it between their lobes and gradually compressing it as the volume diminishes.
Types of Screw Air Compressors
Screw air compressors can be classified into two main categories:
oil-free and oil-lubricated.
Oil-free Screw Air Compressors: Oil-free screw air compressors eliminate the need for oil for lubrication. Instead, they use alternative lubricants such as distilled water, PTFE, or proprietary coatings. These compressors are specifically designed for applications where the presence of even the slightest trace of oil is deemed unacceptable. Industries such as food and beverage production, pharmaceuticals, and research rely heavily on oil-free compressors to ensure compliance with strict purity standards and regulations.
Oil-lubricated Screw Air Compressors: Oil-lubricated screw air compressors incorporate the use of oil for lubrication and efficient heat dissipation. The oil is separated from the compressed air stream, undergoes filtration, and then recycled for continued usage. These compressors are commonly employed in industries where minimal traces of oil are tolerable, such as construction, mining, and automotive.
Benefits of Screw Air Compressors:
Screw air compressors are highly favoured by air experts and industry professionals due to various reasons. Some of them are:
1.High Efficiency: The continuous compression significantly reduces energy wastage compared to reciprocating compressors, where compression occurs intermittently, thus offering increased efficiency.
2.Continuous Operation: These compressors ensure a steady and uninterrupted supply of compressed air. Their design enables them to operate continuously without the need for frequent start-stop cycles, which can compromise both efficiency and the lifespan of the equipment.
3.Low Noise and Vibration: Screw air compressors are notably quieter and generate less vibration compared to other compressor types.
4.Reliability and Low Maintenance: Screw air compressors offer improved reliability and require minimal maintenance. This reduces downtime and lowers maintenance costs for businesses.
