Description of the plate-frame type air filter element
These two images show the front and back sides of the same plate-and-frame type filter element: the front side has pleated filter media, the back side has a metal protective mesh.
✅ Structure composition
1.Outer frame: galvanized steel or aluminum alloy frame, high strength, not deformed; the corners are secured with rivets; Suitable for installation on duct flange; sizes are made to order.
2.Filter material: brown folded filter paper (polyester fiber/wood pulp paper); continuous corrugation significantly increases the filtration area; plastic ribs fix the pitch of the folds and prevent the filter layer from collapsing under the pressure of the air flow.
3.Supporting Protective Mesh: The metal perforated mesh on the back side protects the filter paper from being damaged by air flow and keeps the filter element flat.
✅ Key features
The folded design increases the filtration area: compared to a flat filter, the dust holding capacity is higher, the service life is longer, and the initial aerodynamic resistance is lower.
The metal frame is strong and durable: heat-resistant, does not deform from moisture, suitable for industrial ventilation, air conditioning of server/hardware rooms, work at the inlet of air compressors and other operating conditions.
Ease of installation and dismantling: standard frame sizes; installed directly into the mounting groove of the air conditioning unit or fan cabinet; easy replacement.
Filtration classes available: usually G3/G4 (pre-filtration) or F5–F7 (medium purification); The filter retains particles ranging in size from 1 to 5 microns or more, is used as a preliminary filter at the inlet and protects the subsequent highly efficient filter element.
✅ Areas of application
Pre-filtration of industrial central air conditioners and fresh air supply units
Pre-filtration of precision air conditioners for server and inlet air compressors
Ventilation systems for paint shops and cleanrooms
Primary dust protection of fans and dust collection equipment
✅ Recommendations for use
1.When the pressure drop reaches the rated final resistance (usually 200-250Pa), it is recommended to replace the filter immediately; In most cases, paper models cannot be washed.
2.Installation direction: the filter paper side is towards the air inlet side, the metal mesh is towards the air outlet side.
3.Options available: stainless steel outer frame, heat-resistant filter material; Suitable for high temperature operating conditions.
