Characteristics of Roots blower inside and out thanks to a rotor structure in the form of clover and reasonable housing outlet structure, so the fan vibration, low noise. Fan capacity utilization, high volumetric efficiency, and compact structure, flexible installation. Bearing selection more reasonable, even each bearing life, thus extending the life of the fan! Roots blower product features energy efficient blower factory direct, high-precision, low noise, long life, compact, small size, light weight, wide easy to use, the product uses, throughout the petrochemical, building materials, electricity, metallurgy, chemical fertilizer, mining, ports, textile, food, paper, aquaculture and wastewater treatment, environmental protection industry and many other areas blower housing blower ◆ host chassis, base, wall panels, fuel tank, rotor, manufactured by gray cast iron HT250, resin sand casting, aging treatment. Surface design of the rib-like projections, not only played at a high temperature is not easy deformation, surface and increases the cooling surface area of ??the blower fan manufacturers, the blower case design temperature of 160 ℃. Interface machined to smooth, to ensure airtight assembly. ◆ clover Roots blower rotor made of gray cast iron HT250 manufactured rotor leaf type line arc line. Taiwan uses four-axis CNC machining center with movable, once forming, high precision. Rotor balancing rigorous Roots blower manufacturers, wholesale, accuracy of G2.5 level, so that the exhaust air flow quite smoothly continuous, and shrink fit secured to the shaft blower, between two of the rotor during operation without touching friction, no seal and lubrication. Rotating blades static balance and dynamic balance in line with VDI 2060 Q-6,3, ISO1940 and ANSI S2.19 G2.5 standards.
