These blowers for vacuum or pressure are available in ten sizes from 40mm to 300mm pipe size & 3kw to 75kw power. The LT Series three lobe roots type blowers are a new series of root type blowers. The three lobe design provides better air performance, lower vibrations and noises. It is a significant improvement on the traditional two lobe roots blowers. Traditional roots blowers lubricate bearings and gears with grease and oil, but the LT series is designed to add oil only. It is very easy to maintain as oil has better lubricating properties than grease. The design of these blowers incorporates three lobes instead of the usual two. Benefits of using this three lobe, low pulse design include:
• Lower energy consumption
• Lower noise levels - The three lobe design can efficiently reduce noise by approximately 5dBA.

• Longer bearing life - The bearing life can be extended by approximately 20% as a result of less vibration being transmitted through the lobes

 

Possible Applications:
• Vacuum system for food industry: A roots-type blower can be used in the food industry to remove unedible items from chicken, fish, etc. A separator prevents the product from entering the blower
• Vacuum cleaning: Roots type blowers can also be used as the vacuum source for in-plant vacuum systems. This one shows a barrel emptying system which uses a liquid separator.
• Aeration with low pressure air: Low pressure air is used in sewage treatment aeration tanks. The air is used to support the bacteris, which in turn break down the organic matter.
• Pressure conveying: Positive pressure from a blower can be used to convey product. This example uses a rotary valve.
