Core technology comes from Kaishan North America R & D Center. The “Y-4” Oilless Screw Air Blower Profile invented by Dr. Tang Yan, a world-famous compressor expert, is adopted. Its super-energy-efficient design idea, perfect workmanship and quality assurance, plus world-top machining test facilities, can ensure the high energy efficiency of products, with their reliability reaching the world-leading level.
 |
Highly-efficient screw rotor profile Y-4, exclusively developed for blast blowers. |
 |
Multiple Vi (volume ratio) design, aimed at the demands of different pressure working conditions, providing the main engine with the best efficiency. Precision synchronizer gears, higher efficiency and higher reliability. |
 |
Highly-efficient motor, a large starting torque. |
 |
Air intake filter—high-efficiency low pressure drop, air inflow and outflow silencer design, plus acoustic enclosure, lower noise. |
 |
Complete system design, including air filter, silencer, main engine, motor, starting cabinet, control system, lubricating system, cooling system, acoustic enclosure and base. |
 |
Forced lubricating system, more steady and reliable operation of main engine. |
 |
Kaishan smart controller, colored touch screen, image-text display, friendly interface, simple and easy operation. |
In contrast with Root’s blower, Oil-free Air Blowers can save 35% energy at most
The Energy Efficiency Contrast Diagram between Screw Air Blower and Traditional Root’s Air Blower.
| The pressure/ volume diagram of screw blast blower
Energy consumption / Energy saving ◆ Thermodynamic energy consumption ◆ Energy saving 4→1: Suction 1→2: Internal compression. Intermeshing of opposing rotors, decrease of volume between teeth, and increase of pressure. 2→3: Exhausting. The air is discharged from the pipe. |
The pressure/ volume diagram of Root’s blast blower
Energy consumption ◆ Thermodynamic energy consumption 4→1: Suction 1→2: The air volume remains unchanged. Air is compressed outside due to the backpressure of pipe network. 2→3: Exhausting. The air is discharged from the pipe. |
Performance Advantages of Screw Air Blower Contrasted with Root’s Air Blower:
1. Higher efficiency, lower noise;
2. Allowing a higher rotating speed and tooth-crest speed;
3. Capable of reaching a higher discharge pressure;
4. A lower pressure fluctuation;
5. Root’s blast blower does not have internal compression.
