True Oil-free Air at Class 0 Level
Air purity class of the discharge air from Hitachi Oil-free Screw air compressor (DSP) is proved to be the highest level “Class 0” from the test result which was conducted by the renowned TÜV institute, in accordance with ISO8573-1.
ISO8573-1:2010 CLASS 0 TÜV Certification
TÜV (The Technische Überwachungs Verein), a Germany based international test service provision third-party on aspects of technical safety and quality evaluation, is globally well-reputed on its neutrality and expertise as well as its strictness in testing.
Stainless Steel Rotor
Particular stainless steel, which is superior in corrosion resistance and durability, is applied for rotor with highly accurate grinding.
Furthermore, compensated profile, which is optimized for thermal expansion during operation, enables to keep optimal clearance.
High Performance Coating
Hitachi original coating, which can withstand the high temperature of over 300°C, protects the rotors from a decrease in performance (efficiency, air purity, etc.).
*Necessary to prepare a USB flash memory device (5.5cm or smaller) on user’s side.
*Operation data for one day is approximately 400kB. (For reference)
*Necessary to prepare a Bluetooth® USB dongle on your side.
*For setting changes, part of the items are applicable.
Open network serial communication Modbus®/RTU is supported as standard.
*Modbus®/TCP support is optional.
Comparison of cost with the same air capacity level
Because there is only one air end for DSP single-stage model, the initial cost is lower than two-stage model.
The overhaul cost, which covers the most of maintenance cost, is about half of two-stage for the same reason.
Air capacity increases accordingly at PQ WIDEMODE ON.
0.3 MPa model is newly added
Air capacity is improved by the newly-developed high efficiency air-end.
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.
