Usually, when the industrial dust accumulate to certain extent (explosive limit), in case of static sparks or external ignition or other factors, it’s easy to lead explosion or fire accident. When the weather is dry , it’s easy to accumulate statics causing by the friction and the voltage even can reach to 10 kv , which brings a big threat to the industrial production.

According to this work condition, our company composited several conductive fibers to our product , making the product with the function of anti-static which can eliminate lots of the charge in the bag filters.
