Note that when the Roots blower installation points: 1. Do not set the fan in place is easy to produce organic solvents, paints and other flammable and corrosive gases in case of fire and poisoning. 2. Do not set the fan in person and children often frequented by Roots blower where a good place to prevent injuries and burns. 3, the fan room temperature should be at its forty degrees Celsius, more than forty degrees Celsius will greatly shorten the life of the fan and motor, set the fan to keep the temperature at forty degrees Celsius. ◆ host shell blower Roots blower housing, base, wall panels, fuel tank, rotor, gray cast iron HT250 manufactured by using resin sand casting blower sewage treatment, aging treatment. Surface design of the rib-like projections, not only played at a high temperature is not easy deformation blower, cooling surface and increase the surface area of ??the fan, 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 sewage aeration blower, a molding process, high precision. Rotor balancing rigorous accuracy of G2.5 level, so that the exhaust air flow quite smoothly continuous, and shrink fit secured to the shaft, the rotor during operation without touching the friction between the two, no water 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.
