Three-Lobes Blower Initially, nearly all blowers were of the two-lobed type, and although the design of the three-lobed type was understood to offer the advantages; lower noise and vibraton as well as greater efficiency, construction was difficult. Anlet alone has been able to produce high-performance yet low-cost blowers using a patented three-lobe rotor machining tool. |

Operating Principle The blower is a displacment blower, and sends a fixed amount of air in proportion to its rotation speed. With the three-lobed rotors, the two rotors make six intake and exhaust cycles per revolution, and because the air has less pulses than with the two-lobed type, fluctuations in load are small, mechanical strength is high, and less noise and vibartion are generated. Figure I shows the operation principle. While the two three-lobed rotors mounted on two parallel shafts maintain only a very small clearance between themselves and the inner surface of the oval casing operating chamber and between each other, they are rotated in opposite directions at an equal speed, moving a fixed volume of the air enclosed by the casing and rotors from the intake side to the output side. Because each rotor phase is synchronized correctly by a timing gear, there is no contact. The permits high speed and eliminates the need for internal lubrication. Moreover, the simple design, easy handling and stable performance make possible a wide range of applications. |
