The decision around choosing a suitable air compressor for your business goes beyond affordability and cost. Material handling, spray painting, machine tools- all rely on the mechanisms of a compressed air system to function adequately, if not efficiently enough, to offer the advantages of flexibility in operations, uptime assurance and minimum maintenance.
Therefore, businesses equip their manufacturing processes with screw air compressors.
So, what are screw air compressors?
Screw air compressors or rotary screw air compressors are an advanced version of the original piston air compressors. Using a rotary type positive displacement mechanism, they are the workhorses that provide large volumes of medium to high-pressure air in large factories. The screw air compressors find their use in food production, beverages and medicines, construction, mining, petrochemical engineering and more.
Types of rotary screw air compressors:
Industries and manufacturing plants widely use two types of rotary screw air compressors: oil-free and oil-lubricated rotary screw air compressors. Each of these is unique in their way and are suited for specific purposes.
Oil-free screw air compressors:
In an oil-free screw air compressor, the air is compressed entirely through the action of the screws without the assistance of oil lubrication. Instead, PTFE, distilled water or other proprietary coatings are used for lubrication and heat dissipation. They usually have lower to medium discharge pressure capability as a result. However, higher pressure can be achieved by multi-stage oil-free compressors, where the air is compressed in multiple stages.
Oil-free screw air compressors are used in applications where even the slightest bit of oil contamination cannot be tolerated, including the production of food and beverages, medicines and medical research, packaging, and more.
Oil-lubricated screw air compressors:
Oil is injected into the compression chamber to aid lubrication and adequate heat dissipation in an oil-lubricated rotary screw compressor. The oil is separated from the discharge stream, cooled, filtered, and recycled.
Oil-lubricated screw air compressors are used in applications that require or can tolerate slight levels of oil, such as tools, heavy drilling and mining, metallurgy, mobile tire services, and more.
Benefits of screw air compressors
A. Continuous flow: There is no disruption in the delivery of air for any application.
B. Flexible and durable: They can be designed for extreme weather conditions as well.
C. Lower maintenance costs: The innovative design is ideal for customer needs, ensuring that the equipment functions smoothly and hence no unwanted costs.
D. Low noise output: These compressors run quietly and provide a safe working environment.
