  Airvac vacuum sewers

  Airvac vacuum sewers are a cost-effective, environmentally friendly alternative to traditional gravity and pressure sewer systems providing low maintenance, efficient and reliable sewage collection.
  
  
  Features
  1. The excavation depth of vaccum pipes are about 0.8 to 1.5 meters. The advantage of vacuum sewers are rapid construction, small damages, flexible piping configuration without obstacle migration, etc.
  
  2. As an auxiliary system of the gravity system, it can effectively reduce the depth of the pipelines in the region, significantly reducing its construction costs.
  
  3. No pipeline plugging, no odor leakage problem in closed system, no effluent seepage or groundwater infiltration

  KAWAMOTO Inverter package booster

  
  
  Features
  1. Energy saving drive. Silent and highly energy-saving operation is possible due to adoption of low sound inverter, high efficiency motor, and improved pump efficiency.
  
  2. Sanitary stainless. Cast stainless steel are adopted for major parts, so durable and sanitary
  
  3. Soft start. Starting current is reduced by inverter control. Soft start reduces the negative impact on the power source such as voltage drop, etc
