Roots Blower widely used for air supply, dust extraction, material conveying, and cooling in factories, wastewater plants, and ventilation systems. High-efficiency designs ensure reliable performance under heavy-duty conditions.
Product Introduction
Double oil tank three -lobe Roots blower is a Positive displacement blower There are two impellers on the two parallel shafts, There are some tiny gap between impeller to bodycasing , impeller to impeller.
The impellers rotate in opposite direction , a certain air will be absorbed at inlet port and transferred toblower’s outlet port.
Each impeller always keeps the correet phase by the synchronous gears, not touching each other. So theycan rotate at high speed without any lubrication inside, And it is simple structure, running smoothly.performance stabilization.
Product Advantages
- Helical synchronous gear: smooth operation and low noise.
- All bearings are the Japanese NSK bearing.
- The oil seal is used CR seal imported from USA.
- Cooling way is air-cooling and water-cooling.
- The impeller uses the impeller & shaft integrated structure , high accuracy.
- Compact structure, the same inlet and outet impeller structure, flexible installation.
- There are various installation ways. The air blower can be installed into horizontal air inlet and vertical air inlet using the same bottom base frame.
- It can also change the position of the drive shaft, right shaft or left shaft drive, uppershaft or lower shaft drive.
Application Field
1.Wastewater Treatment
Blowers provide aeration in sludge tanks, enhancing microbial activity.
2.Food Packaging
Vacuum blowers secure packaging films during sealing, ensuring airtight precision for freshness preservation.
3.Aquaculture
Blowers deliver oxygen through diffusers to maintain dissolved oxygen levels for fish survival.
4.Printing Industry
Screen printers use blower-generated vacuum pressure to hold materials in place for accurate printing.
