1. air pre filter Description


The preliminary filter is the primary filter of the air conditioning system and is mainly used for filtering dust particles above 5μm. The initial filter is available in plate, folding and bag styles.

The frame materials include paper frames, aluminum frames, and galvanized iron frames.

The filter materials include non-woven fabrics, nylon meshes, activated carbon filters, and metal meshes.

The protective meshes are double-sided sprayed wire mesh and double-sided galvanized wire mesh.


2. air pre 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).


3. air pre filter Structure


1) The outer frame of the filter consists of a sturdy waterproof sheet to fix the folded filter material. The diagonal design of the frame provides a large filter area and allows the internal filter material to adhere tightly to the frame. The perimeter of the filter is bonded with a special professional adhesive glue to the frame to prevent air leakage or damage due to wind resistance pressure.

2) The outer frame of the disposable paper frame filter is generally divided into a general cardboard frame and a high-strength die-cut cardboard, and the filter element is a pleated fiber filter material lined with a single-faced wire mesh. Beautiful appearance, Rugged and durable structure. General cardboard frame for the manufacture of non-standard filter, can be used for any size filter production, high strength, not easily deformed. High-strength die-cut cardboard is used for the manufacture of standard-sized filters, characterized by high specification accuracy and low aesthetic cost. If the imported surface fiber or synthetic fiber filter material is used, its performance indicators can meet or exceed the import filter.

3) The filter material is folded into a high-strength die-cut cardboard, increasing the windward side area. Dust particles in the inflow air are effectively blocked by the filter material between the pleats and the pleats. The clean air flows evenly from the other side, so the air flow through the filter is gentle and uniform. Depending on the filter material, the particle size that it blocks varies from 0.5μm to 5μm, and the filtration efficiency is also different.
