Reduced air consumption Direct Operated Precision Regulator Greatly reducing the bleed air flow compared with the conventional model (ARP3000)  Constantly bleeding a small amount of air in order to make precise pressure adjustment possible  Interchangeable mounting available ARP3000 → ARP30 (No equivalent models for APR20 and 40 are available since they are newly added ones.) Series ARP20 to 40 Energy-saving Model Conventional Model When setting 0.3 MPa 0.8 l/min (ANR) or less When setting 0.3 MPa 4 to 6 l/min (ANR) When air supplying time is 24 hours/day, 250 days/year When air supplying time is 24 hours/day, 250 days/year 288 m3 or less/year (\430/year) Energy-saving model Conventional model 80% Corresponding value: Air unit \1.5/m3 (ANR)  Refer to the catalog for details.
