Product Description

Mini pleat pre filter for primary filtration of ventilation system



1. Primary filter description

The use of metallic materials as a framework for the initial effect filter feels rather Chinese characteristics. The choice of filter material is basically the same as the disposable paper frame. The main reason for making the metal frame is durable and cost-effective. Thanks to the use of a metal frame, it is only necessary to replace the inner filter element whenever the filter life is reached, thus saving costs.
Due to the reasons of structure and cost, the preliminary filter of metal frame generally uses non-woven fabric as filter material. However, it should be noted that some users always require filter manufacturers to use washable filter materials. In principle, as long as any filter material is rinsed with water (including rinsing), its filtration performance will be greatly reduced, so the parameters will all become bad, which will lead directly to filter scrap. Even if some filter materials can be used for flushing, it is at the cost of severely reducing filtration efficiency. Therefore, it is not recommended to extend the service life at the expense of filter performance. The correct method of use is to replace the filter element.


2. Primary filter Feature

Cheap, Light weight, Versatile, Compact.

Mainly used:

● Central air conditioning and centralized ventilation system pre-filtration

● Large air compressor pre-filter

● Clean air return system

● Pre-filtering of local high-efficiency filtration devices

● High temperature air filter with stainless steel frame, high temperature resistance 250-300°C

The pre filter, which is commonly used for primary filtration of air conditioning and ventilation systems, is also suitable for simple air conditioning and ventilation systems that require only one level of filtration.

G series coarse air filters are divided into eight categories: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (active carbon filter), GT (high temperature coarse filter).
