AMC Filtation
In the environment for human survival, not only filled with dust particles of different sizes, but also mixed with a variety of modular pollutants, they are quietly eroding our environment, equipment and health.
Molecular Gaseous Pollution will lead to the corrosion of electronic component. So that it causes the failure of the products and increased the cost of operating costs. Besides, bad smells reduced the comfort of employs greatly and do harm to the health of human beings potentially.
HEAFIL has been in the field of air filtration for more than 20 years and accumulated a lot of successful clean air solutions. We can provide customized solutions to clean air. And we gathered various molecular control particles and media which can help remove molecular pollution effectively to protect the production process and human health.
。
Referring to types and concentrations of the molecular, as well as the odor intensity, we make plans for filtration solutions to ensure the effect is achieved. It is a honor and pleasure for us to provide molecular filtration solutions and optimization advice. So that there is a correct filtration solution to your production process.
1. AVOID CORROSION
