DFSR-WN Oil free electric roots air compressor with CE ISO for steam
MVR Roots Steam Compressor
Our company's DFSR-WN Oil free electric roots air compressors with CE ISO for steam have been developed with air capacity from 5 m3/min to 130 m3/min. The maximum pressure difference between inlet and outlet is 58.8Kpa to 80Kpa.
Specific parameters are shown in the following table:
| Model | Air capacity
(m3/min) | Differential pressure
(Kpa) | Rotating speed
(rpm) |
| DFSR-100WN | 5-9 | 58.8-80 | 1000-1650 |
| DFSR-125WN | 10-22 | 58.8-80 | 870-1650 |
| DFSR-150AWN | 20-30 | 58.8-80 | 980-1580 |
| DFSR-200BWN | 24-45 | 58.8-80 | 930-1550 |
| DFSR-250WN | 45-76 | 58.8-80 | 750-1250 |
| DFSR-300WN | 75-130 | 58.8-80 | 750-1250 |
Note:
1. The air capacity in the table is measured when the pressure difference between the inlet and outlet is 40Kpa. The maximum allowable pressure difference of the actual MVR compressor can be:
A- FSR-250WN, FSR-300WN, the maximum allowable differential pressure is 60Kpa
B- FSR-100WN, FSR-125WN, FSRSR-200WN, FSRSR-250WN, the maximum allowable differential pressure is 80Kpa.
2. In the table, rotating speed is the recommended value. Don't try to exceed the range.

MVR roots steam compressor features
Shell: The inlet adopts spiral type. When the impeller rotates, the gas enters the shell through the spiral line to form a circular cavity, thus reducing the pulsation of the blower.
Material selection 304/316L/2205/HT200+Ni-P
Rotor: Three-leaf or two-leaf type, compound type line, Impeller area utilization factor 0.5, volume efficiency increases 5%, noise reduces about 5dB
Material selection 304/316L/2205/HT200+Ni-P
Wallboard: The surface is provided with a backflow groove. This structure can increase the compression ratio of the blower and can also help reduce the noise of the blower.
Material selection 304/316L/2205/HT200+Ni-P
Mechanical seal: Double-faced container-type mechanical seal, moving ring using silicon carbide or graphite, static ring using carbide steel, easy installation and maintenance, special design structure, use more reliable.
Bearings: Positioning bearings are NSK bearings that are imported from Japan.
Gears: High-precision grinding gears are used to reduce mechanical noise, and the accuracy reaches level 5 of the national standard GB/T10095-2008.
