AHU Flat panel fiberglass filters Manufacturer in China

Material composition:

  • Frame – aluminum alloy, galvanized sheet, corrugated cardboard
  • Filter material – glass fiber filter material

Flat panel fiberglass filters are suitable for pre-filtration of various clean ventilation systems, protection and filtration of central air-conditioning heat exchange components for general ventilation requirements, and return air filtration of various industrial clean workshops or civil buildings.

In order to meet the air filtration configuration problems of various user air conditioning systems, it has the following forms:

  1. Efficiency specification G2-F6 (initial effect to medium effect).
  2. Outer frame (cardboard, aluminum alloy, galvanized sheet, plastic).
  3. The filter material is tiled.
  4. Filter material: fluffy fiberglass felt.
  5. The filter has low resistance, large dust holding capacity, and is easy to disassemble and replace.
  6. The design of the metal frame can be used in high temperature environments.
  • Flat panel fiberglass filters can capture particles above 5um, dust and various suspended solids.
  • Large air volume, low resistance, high dust holding capacity, flame resistance, good chemical properties, low hygroscopicity, and can be used for a long time in an environment of 150 degrees.
  • Can be washed and reused many times. High dust holding capacity, economical and practical, strong heat resistance, no fracture phenomenon.
  • The filtration efficiency is higher than the initial efficiency of nylon mesh.
  • Low resistance, large air volume and thin thickness.

Application areas:

  • It can filter banana oil, soot, dust and other particles generated in the high temperature drying room.
  • Structural materials:
  • Frame material: aluminum alloy, stainless steel, galvanized iron
  • Filter material: special organic synthetic fiber, glass fiber
  • Temperature: 150℃, Humidity: ≤80%,
