Product Details
The working principle of PURE air filter is based on physical filtration, using specially designed filter paper or fiber materials to form a multi-layer filter. When the air passes through, larger particles will be intercepted by the surface, and small particles will be captured by the deep filter material, thereby ensuring that the air cleanliness entering the combustion chamber meets the standard requirements.
