Functions: – Minimizes turbulence in the air compression process. – Fence in the process of air compression. – Protection against oxidation and loss of efficiency. Importance of technical monitoring and maintenance: – The rotors (screws) and the housing have a clearance less than 0.05 mm between them. – Any material between the rotors and the housing results in Teflon desquamation, loss of efficiency and damage to the compressor unit. – 25mbar of pressure drop in the air intake, reducing the total flow of the equipment by 2%.
