ROTARY VACUUM FILTER - NEOTECHS

The filtered solid body cake is removed from the filter by the blower gas continuously. Thus this enhances the efficiency of the filter remarkably. As this vacuum system filters slurries in large volume in succession the filtering costs per ton drastically drop down comparing to the conventional filters. And the system is designed compactly to give much more freedom in installation space.

What are high efficiency rotary nozzles and why

05/08/2019  Rotary nozzles improve irrigation efficiency by delivering water more slowly. That prevents runoff by giving soil time to absorb the water and allows the water to reach the root zone of the plant. These nozzles also deliver water in a larger droplet size, making the spray less susceptible to being carried off by the wind. This is all accomplished via their distinctive multiple rotating streams of water,
