The Pleated Primary Air Filter is a medium efficiency disposable air filter, suitable for ventilation and air conditioning systems , which require a higher efficiency and greater dust holding capacity.
The G4 Pleated Paner Air Filter can be used where glass panels are undesirable, such as in the food industry and hospitals.Typically G4 Pleated Panel Air Filters are used as pre-filters on supply air systems , or to protect heating or cooling coils from dust build up ,which leads to system inefficiency.
Another common place to see a G4 Pleated Panel Air Filter is to protect fans in extract systems for office blocks or kitchen extract systems.
● Low resistance
● High dust holding capacity
● Large filtration area
Pre- filter and foreign material filtration in commercial and industrial ventilation systems.
1. Used for clean room conditioning system, pre filtration through fresh air venting units, and exterior air conditioning connection.
2. Primary filtration of central air conditioning system.
3. Pre filtration at the inlet of air purification equipment.
4. Pre-filtration in a medium filter.
5. Glass fiber plank pre filter In Ventilation system for outdoor fire proof and high temp resistance working condition.
