Introduction:
Primary filters, also known as coarse filters, are usually made of synthetic fibres. Primary filter is suitable for the primary filtration of air-conditioning system, mainly used for filtering dust particles above 5μm. As the pre-filter of the air filter, it can effectively block the dust particles in the air and protect the back-end intermediate and high-efficiency filters.
Pleated panel primary air filter can not be cleaned, should be regularly tested and replaced in a timely manner when the filter does not meet the expected filtration effect. Generally speaking, the primary filter needs to be replaced once every 3 months, and the specific replacement time needs to be determined according to the specific use situation.

Characteristics:
Frame: Cardboard/Aluminium/Galvanized
Media: Synthetic fiber (non-woven)
Efficiency: G3,G4 (EN779) / MERV8 (ASHRAE 52.2)
Max. Temperature: 80℃
Max. Relative Humidity: 99% RH Rec.
Features:
1.Lightweight panel construction for easy handling and installation.
2.High quality polyester synthetic fibre filter material with low initial resistance, good fire resistance and long service life. The fluffy and dense fibre structure ensures high dust collection rate and large dust capacity, which effectively prolongs the service life of the back-end medium-effect filter and reduces the operating cost.
3.Various frame materials are available - paper frame, galvanised frame, aluminium frame. The galvanised frame and aluminium alloy frame have a sturdy structure, which ensures that the filter will not be deformed or damaged even under poor working conditions.
