DIMENSIONS

Heavy duty and reliable piston-operated FR + L unit.

• Stability of the set pressure as the upstream pressure varies

• Metal bowl with external sight glass

• Semi-automatic and automatic condensate drain

• Quantity of lubricant proportioned to air flow

• Micrometric lubrication regulation

• Activation guaranteed with low flow rates

Refer to the sections on the single modules for a further description,
