What is an Oil-Free Rotary Compressor?
Oil-free rotary compressors compress air without utilizing lubricant in the compression chamber. Within the dry compression chamber, contactless intermeshing rotors typically coated with a type of PTFE coating create compression.
Why Choose an Oil-Free Rotary Compressor?
Oil-free rotary compressors don’t use lubricant. Because these compressors don’t use lubricant, oil-free rotary compressors are typically two-stage utilizing an intercooler to remove heat caused by compression. Also, the lack of sealing fluid requires much higher rotational speeds than typical oil flooded type compressors.
Oil-Free Rotary Compressors are Safe and Efficient
Oil-free rotary compressors create oil-free air. This eliminates the possible contamination of products downstream that may come in contact with plant compressed air. If your company is in a position where air quality is critical and costs of product contamination are high, oil-free rotary compressors should be considered. And because of the oil-free design, the compressors are easier on the environment and the total cost of ownership is reduced significantly.
Buying an Oil-Free Rotary Compressor
Companies operating in food production, instrument air, laboratories, medical, chemical production, and power generation would be good fits to purchase an oil-free rotary compressor. Things to consider is whether oil-free air is absolutely mandatory in your company’s production. Oil-free rotary compressors are typically more expensive and have a short lifespan because of the higher temperatures and air-end speeds. Also, if compressed air comes in contact with the final manufactured product and the potential for damage or spoilage is high, oil-free rotary compressors is the correct choice for your air compressor.
