2 Hitachi Social Innovation Environment Friendly, High OilFree Rotary Screw Compressor (DSP) Since the first Hitachi air compressor (1911), Hitachi has become one of the global leading manufacturers in air compressor. With the concept 'Toward the next 1 years, Contribute to Environment and EnergySaving', Hitachi coit ourselves to unstoppable effort in technology innovation. With high standard reliability, excellent EnergySaving and various air solutions, Hitachi will contribute to the industrial growth and development. Premium Air Quality True OilFree Air at Class evel Test and analysis of condensation of oil in the discharge air of Hitachi Oilfree Screw Compressor (DSP) are implemented by third party (TÜV) based on ISO85731 standard. y the test result, oil contained in the discharge air of Hitachi DSP is proved and certified as the highest level of quality air Class. ISO85731:21 CASS TÜV Certification TÜV (The Technische Überwachungs Verein), a Germany based international test service provision thirdparty on aspects of technical safety and quality evaluation, is globally wellreputed on its neutrality and expertise as well as its strictness in testing.

Cut Down Overhaul and Initial Cost Comparison of cost with the same air capacity level ecause there is only one airend for DSP SingleStage model, the initial cost is lower than TwoStage model. The overhaul cost, which covers the most of maintenance cost, is about half of twostage for the same reason. Expanded ineup (ow ).3 model is newly added Air capacity is improved by the newlydeveloped high efficiency airend. Applications In case that the pressure requirement is higher than blower but lower than standard compressor SPEC, low pressure SPEC DSP can be your solution. 22 SPEC.3 SPEC 1 5 Capacity Comparison Comparison of Overhaul Cost (%) Instrumental Panel Control Panel SingleStage TwoStage SingleStage TwoStage Comparison of Initial Cost (%) Example of Hitachi (SingleStage) and 45 (TwoStage), model Air low Main Production ine ow Equipment Powder Transport () Powder AirCooled, (15) Unit Intake Air /Temperature Discharge Air Pipe Connection Oil Quantity Cooling Fan Motor Output Coolant Pump Motor Output (5/6Hz) P.D.P [Dryer] Refrigerator Nominal Output Refrigerant Sound evel (1.5m from front) d(a) AirCooled, Vtype (22) Unit PQ WIDEMODE PQ WIDEMODE Range Intake Air /Temperature Discharge Air Pipe Connection Oil Quantity Cooling Fan Motor Output Coolant Pump Motor Output (5/6Hz) P.D.P [Dryer] Refrigerator Nominal Output Refrigerant Sound evel (1.5m from front) d(a) WaterCooled (/) Unit PQ WIDEMODE PQ WIDEMODE Range Intake Air /Temperature Discharge Air Pipe Connection Oil Quantity Cooling Fan Motor Output Cooling Water Flow Rate Cooling Water Temperature Cooling Water Pipe Connection Sound evel (1.5m from front) /min d(a) 2.
