Interception functionPhysical size interception: The filter screen is the core component of the pre filter. When a fluid containing impurities passes through the filter screen, impurity particles larger than the filter aperture will be blocked on one side of the filter screen and cannot pass through it, thus achieving the filtration of large particle impurities. For example, in an air pre filter, larger particles such as dust and hair are intercepted by the filter screen; In the water pre filter, large particles such as sediment and rust are also blocked by the filter screen.Inertial collision interception: When impurity particles in a fluid move at a certain speed, due to inertia, they may deviate from the streamline of the fluid, collide with the surface of the filter, and be intercepted. This inertial collision interception is very effective in removing impurity particles with certain mass and velocity.Adsorption effectSurface adsorption: Filter materials usually have certain adsorption properties, and their surfaces can adsorb impurity particles in the fluid. When impurity particles come into contact with the surface of the filter, they will be adsorbed on the filter due to the intermolecular attraction, thereby further removing impurities from the fluid. For example, activated carbon filters can adsorb odors and harmful gases in the air, as well as residual chlorine and organic matter in water.Chemical adsorption: Some pre filter mesh materials undergo special treatment and have specific chemical activity, which can react chemically with impurities in the fluid, form chemical bonds or complexes, and fix impurities on the filter mesh. This chemical adsorption has a good effect on removing certain special impurities, such as heavy metal ions.Precipitation effectIn some pre filters, the flow rate of the fluid decreases, allowing sufficient time for impurity particles to settle to the bottom of the filter or the surface of the filter screen under the action of gravity. Then, the precipitated impurities are removed through regular discharge or cleaning to maintain the filtering effect of the filter. For example, sedimentation pre filters in some water treatment systems work basedon this principle.In summary, the pre filter works together in multiple ways to effectively intercept and remove impurities in the fluid, protect subsequent equipment from damage, and ensure the normal operation of the system and fluid quality.Quote Inquiry Contact us!
