Pleated Panel Filters

Pleated Panel Filters

Pleated panel filters are disposable and often used in heating, ventilation and air conditioning systems (HVAC). It is manufactured from a G4 filter media consisting of non-woven cotton fibres that are excellent for collecting dust and are also treated with flame retardant additives. The cotton fibres are laminated onto a mesh backing and pleated during manufacturing to allow consistent airflow through the filter. The finished pleated panels come in a heavy duty cardboard frame box with excellent resistance to tear when wet or dry.

Typically, airflow is lowest at the bottom of the pleat, where contaminants are filtered out. As pollutants build up, the resistance at the bottom of the filter increases, resulting in airflow moving up the side of the pleat. These filters provide an average energy efficiency saving of 30-35% and an arrestance of 93%.

Pleated panel filters are popular in food, drink and pharmaceutical industries where glass fibre is prohibited. They are used over glass or synthetic panel filters when a more significant dust holding capacity is required. Also commonly used in waste air and ventilation systems to filter coarse dust particles such as pollen and fog or to protect against pollution in air conditioning or compact instruments. In public protection equipment, they act as circulation filters and can also be applied as pre filters.
