The fist generation, 2-lobe blower was composed of 2 pean-shaped rotors.
Sucking and discharging air 4 times per rotation the 2-lobes blower had many problems, including great variations in pressure, vibration and noise.
it was difficult to process and hard to make its axis larger,thus weakening it .
The second-genration, 3-lobes blower had much less variation in pressure, vibration and noise,since it sucked and dischared air 6 times per rotation .
The third-generation, 3-lobes helical blower greatly reduced pulsation, vibration and noise,and removed axial thrust by consecutively sucking and exhaling air without and exhaling air without and pressure difference.

DESCRIPTION
1 BLOWER

5 FLEXI-CHECK
6 BELT ASS'Y
7 SAFETY VLAVE
8 ANCHOR BOLT
9 ANTI-VIBRATION MOUNT
This rotary blower, or 'Roots blower' has two built-in rotors, a motor, noise silence for suction and other parts.
Principle of operation
Two rotors move in opposite directions within a casing while keeping a suitable clearance between casing and rotors.
In a case of 2-lobes rotor,this operation occurs 4 times per rotation; a 3-lobes, 6 times; and in a case of helical rotor, it occurs consecutively. In all cases, the air moves towards the exhaust in proportion.
Regarding to Seloction of Blowers
Our product can be used in a various use, selocted by customer's purpose and ordered by data sheet & order specification.
To a degree of pressure difference & vacuum level air cooling, water cooling,back flow cooling and multistage cooling type can applied.
For a discharge port noise can be extinguished inside pipe,discharge silencer is not necessary spec.
In a case of much less noise & vibration, acoustic hood & anti-vibration rubber can be chosen in a option item.
In a case of direct coupled type, power loss is prevented by a degree of 3-5% in a point of view transmission efficiency.
Helical type can be applied from 80A to 300A.
