Air Control Units (FRL's)
The operational safety and durability of a pneumatic circuit depends on the quality of the compressed air. The compressed air and the moisture increase the rate of wear of the surfaces and seals, reducing the efficiency and the life of pneumatic components. Furthermore the pressure fluctuation due to a discontinuous demand of air, adversely effect the correct operation of the circuit.
To eliminate these disadvantages it is essential to install the service units: filter, pressure regulator & lubricator.
