Filtration efficiency:

BS plate filter has two filtration efficiencies, G3 and G4, corresponding to gravimetric efficiency of 80%~90% and colorimetric efficiency of 40%. Filters with this efficiency can be used for pre-filtration to protect downstream filters, or for simple air conditioning and ventilation systems that only require one-stage filtration.

Why choose primary effect plate filter

Prolong the life of the back-end filter

Effectively intercept large particle pollutants, reduce the load of medium-efficiency and high-efficiency filters, and reduce the frequency of replacement.

Low resistance design

Ensures good air circulation performance and reduces fan energy consumption and system operating costs.

Large dust holding capacity

It can store more dust particles and extend the maintenance cycle.

Easy to install and replace

Standardized structural design, suitable for most air treatment equipment and filter boxes.

A variety of specifications are available

Support customization of different sizes, thicknesses and filtration levels.

Economical and efficient

With low purchase and maintenance costs, it is the most commonly used pre-filtration solution for HVAC systems.

Main features

• Low initial resistance
