...without using oil and lubricants

Dry compressors are  used in the chemical, petrol chemical and food industry, as well as in the gas compression process without using oil or lubricants.
The choice of the sealing elements and of the running rings’ material is the premise for the device’s good working. The rings must be able to grant a great resistance to wear and compatibility to the values of pressure and temperature. Ptfe is the ideal integration element for this development because it can easily be mixed with organic materials, generating  mixtures  which are perfect for the dry working. This mixture can grant a considerable durability also at different pressures, high speed and different fluids without lubrication.
