Air Knife Dewatering Unit
Applications
The dewater air knife can remove the residual water after cooling as well as reduce the moisture content of materials. It is an efficient machine developed for the production and improvement of of engineering plastics and color masterbactch processing industries. It can adapt to high water, high temperature, high humidity, high dust and other harsh production environments.

Operational Principle
The dewater air knife uses a negative high-pressure produced by the high-pressure blower in order to quickly remove the surface water of the wet materials. The gas-liquid mixing flow separates the liquid through the high efficiency eddying flow and automatically collects it in the tank for discharge.
- The moisture content of a typical nylon product treated with this equipment can be stabilized below 0.08% due to its superior suction. The dehydration efficiency is higher than that of a traditional air blower, and the surface water removal rate is above 99%.
- The air knife dewatering unit is suitable for high glass fiber reinforced products with a wear-resistant ceramic suction head. It not only has a small resistance to passing through the material, but is also easy to clean.
- The air knife dewatering unit can be used for the dewatering of LFP long glass fiber reinforced material due to the guide slot that is designed to prevent material blocking.
- The air knife dewatering unit uses backwash flow to prevent the drain from being blocked for long periods of time.
- It achieves a high - efficiency separation of gas and liquid using the multiple-cyclone separator in the case. It will not be blocked, and it is easy to clean, with the suction head wind speed reaching up to 25m/s due to the lack of a filter and the small wind resistance pressure loss.
