Mr Bob MccabeWe have purchased 6 sets Roller Shutter Door for our candy factory from your company. Good quality! Good sevice! We will purchased other clean room equipment from your company later.
Mr ManhThis year we are going to build a mobile phone screen electronics clean factory.We send Hongkong YaNing a list of products we need,Unexpectedly, they soon gave me a very detailed quotation and drawings, and gave us a lot of good advice. Very professional, good service, good product quality! We decided to place an order.

Covering wire mini-pleat G4 primary filter with aluminum frame
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.
● 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.
