All kinds of pleat pre-filters with aluminum frame for primary filtration

1. Primary filter description

Primary effect air filter is suitable for primary filtration of air conditioning system, mainly used for filtering dust particles above 5um (micron); generally used for pre-filtering of central air conditioning and centralized ventilation systems, pre-filtering of gas turbines and air compressors; Only a simple filter and simple air conditioning and ventilation system are required.

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).

3. Primary 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.
