An oil-less oil free air compressor operates without the need for oil lubrication, which means it requires different types of seals compared to oil-lubricated compressors. One of the key seals in an oil-less compressor is the piston seal, which helps to maintain air pressure inside the compression chamber.
The piston seal is located between the piston and the compression chamber wall. As the piston moves up and down, it creates compression and moves air into the tank. The piston seal prevents air from leaking past the piston and ensures that the compression process is efficient.
Oil-less compressors typically use a synthetic piston seal made from materials like Teflon or Viton. These materials are designed to withstand high temperatures and resist wear and tear from constant use. Synthetic piston seals offer several advantages over traditional oil-lubricated compressor seals:
No oil contamination: Oil-less compressors don't use lubricating oil, which means there is no risk of oil contamination in the compressed air supply. This makes them ideal for applications that require clean air, such as painting or food processing.
Reduced maintenance: Because oil-less compressors don't use oil, there is no need to change or top up the oil levels. This can save time and money on maintenance costs.
Longevity: Synthetic piston seals are designed to last longer than traditional oil-lubricated seals, which can wear out faster due to exposure to oil.
However, it's important to note that oil-less compressors may require more frequent replacement of piston seals compared to oil-lubricated compressors. This is because synthetic seals are typically softer than traditional seals and may wear out faster due to constant use.
If you experience a drop in air pressure or notice air leaking from your oil-less compressor, it may be time to replace the piston seal. Consult the owner's manual for specific instructions on replacing the piston seal and seek professional assistance if necessary. Regular maintenance and inspection of the piston seal can help to extend the life of your oil-less compressor and ensure it operates at peak efficiency.
