Professional Advice

In the field of cardboard air filter frames, different filtration grades and working environments have varying requirements for cardboard air filter frames. To ensure you choose the most suitable cardboard air filter frame, we will make recommendations based on your specific needs and provide you with comprehensive technical support throughout the process.

Firstly, the selection of cardboard air filter frame varies with different filtration grades. Generally, a 1.2 mm thick cardboard is used for primary filters, while a 2 mm cardboard is more suitable for medium efficiency filters.
At the same time, different working environments have different requirements for the properties of the cardboard. For example, if the working environment is relatively humid, choose to make the cardboard waterproof and moisture-proof. If it is relatively dry, no additional treatment is needed.
In addition, we provide die-cutting equipment and have extensive experience in this field. If you encounter any problems during production, we will do our utmost to provide you with technical support.
