Product Description
The helical construction uses the stator helical method that the screen lines of casing at the suction and discharge sides are cut to a helical shape, and the triangle suction and discharge sides port formed by a straight line of the rotor top is to be opened and closed gradually.

Therefore, the suction and discharge ports of this type is not opened or closed at moments, which makes these blowers have an only limited operation sound and almost free from pulsations from discharges.

The rotors are three-lobe straight type, so that the rotors can not interfere with each other, resulting from minor displacements in the thrust direction as in the helical type. Therefore, the clearance between the rotors should be assured in the profile direction only and thus there is no necessity of an excessive clearance on account of displacements in the thrust direction as in case of the rotor helical type. From such reasons, these blowers have a very high efficiency, in comparison with the rotor helical type of same dimensions.

By adoption of an unique profile of rotor, the clearance between the rotors can be held to be constant, which makes the efficiency even higher.

The precision of rotors is fully controlled and variation of precision between blowers is almost nil because the rotors are produced under the mass production control by utilizing a prenision NC matching. In addition, the rotors are dynamically balanced in the fabrications as in the case of conventional rotors which are still unbalanced.

The advancedest driving gears are adopted not only to extend the use life but also to make noise lower. The gears are made in special Cr-Mo steel by hardening treatment and are made according with gear precision of JISI first-class. Therefore, the harmful disturbances to products from gears are avoided.

The transported air is clean and is any oil-dust free oil lubrication is not needed in casing and the structure design present the bearing oil and gear oil from entering the casing.

With the establishment of quality management system and manufacture management system, the aims of parts exchanging, less production cost and rapid delivery are realized. The blowers of right quantity are keeped in stock to make delivery in time.

Greentech International (Zhangqiu) Co., Ltd is the professional roots blower supplier. The NSRH type clover spiral Roots blower on the basis of the manufacture and sale of a Roots blower for many years the development of new products using new technology.
The machine through the use of new lines on the impeller, the overall adiabatic efficiency and volumetric efficiency is further improved, and is excellent particularly in the fan of the air volume and pressure characteristics.
So-called excellent efficiency is the amount of heat generation of the wind turbine itself is reduced, i. e. The temperature rise dropped, the various models using the exhaust pressure in the dry state is up to 1kgf/cm2.
