Diameter 43mm standard size 1.7mm thickness anodized aluminum alloy tube for Karakuri system. We are the manufacturer of aluminum tubes. Our products are sold directly from factories. With low prices and large shipments, we are the best choice for dealers. 43 series aluminum pipes are typically used in environments with higher requirements for load-bearing capacity. The aluminum tube with a thickness of 1.7mm can provide the user with sufficient bearing capacity. Compared with the traditional lean pipe, the aluminum pipe has less resin coating. Because the supporting connectors are also aluminum materials, it is easy to recycle when doing waste treatment. Moreover, the surface of the aluminum pipe is treated with acid resistant aluminum, and it can be kept beautiful for a long time without maintenance. At the same time, the aluminum tube surface is also coated to reduce oxidation and keep the factory clean. Features 1. WJ-LEANâ??s aluminum tube use international standard size, can be used in any international standard parts. 2. Easy assembly, only needs a screwdriver to complete the assembly. The material is environmentally friendly and recyclable. 3. Aluminum alloy surface is oxidized, the surface is smooth without burrs, and the overall system is beautiful and reasonable after assembly. 4.Product diversification design, DIY customized production, can meet the needs of different enterprises.

Rotary Air Blower Product Description The Rotary Air Blower utilizes an involute profile integral shaft ductile iron impeller design. The head plate, gear cover, end caps and rigid one-piece housing are made of gray cast iron. Carburized and ground alloy steel timing gear tapers are mounted on the shaft and secured with locknuts. Cylindrical roller bearings are used on the drive end and ball bearings on the gear end. The characteristics and advantages of rotary blowers 1. Small size, large air volume, low noise, and low energy consumption (the rotary blower adopts the principle of operating compressed air, although small in size, it has high air volume, energy saving, and operates quietly) 2. The operation is smooth and the installation is very convenient (for small models, as long as they are placed properly, the vibration is minimal and there is no need to install anti vibration devices, making the installation very convenient). 3. Resistance to load changes and stable air volume (for example, if the pressure of the sewage treatment aeration tank changes, the load changes, but the air volume also changes very little with the pressure change). 4. Equipped with an air chamber for smooth air dissipation (all models are equipped with an air chamber to prevent air pulsation and ensure smooth air dissipation). 5. The material is excellent, the structure is clever, and the performance is excellent (all blowers are made of high-quality materials, the structure is exquisite, sturdy and durable, and the performance is excellent, with few faults occurring during long-term use). 6. Simple maintenance, few malfunctions, and long service life (low speed, low wear, and long service life).

Product Description Roots vacuum pump is a dry positive displacement pump. They operate on the Roots principle, which is similar to that of rotary vane pumps. These pumps are the ideal solution when fast pumping speeds are required. In the case of contactless, oil-free compression Roots booster pumps, two symmetrical cams rotate in the working chamber. During this process, the rotating blades do not come into contact with each other or the housing. Roots vacuum pumps are often used in pumping stations in combination with oil-lubricated rotary vane pumps to achieve very high volume flows and deep final vacuums. Benyuan's three-lobes roots vacuum pump is an internationally advanced roots blower produced by importing and digesting patents and proprietary technology from the American Hibar company and utilizing the company's advanced manufacturing processes. Features 1. Air cooling. Pressure rises to -50 kpa 2. Small size, lightweight, dual-purpose for both vertical and horizontal use, convenient to replace European and American models 3. High-speed, energy-saving 4. Belt self-tensioning technology, easy to use and maintain 5.Impedance-integrated composite muffler with good noise reduction effect
