Multi-film gas sampling bags are made of layered films that consist of polyethylene and aluminum films. It has a stronger ability to resist gas permeation than any other films. This kind of bag is widely used in petroleum chemical industry, environmental monitoring, scientific experiments for gas sample collection and preservation.
Fitting type: Metal connecting type,Double metal connecting type, Model L Valve , Model L of Double Valves ,Straight Pole Valve,Straight pole of double Valves.
Features:
Non-permeable
Opaque - to protect collected gases against ultraviolet light
Do not chemically interact with gases
Simple to maintain and do not require technical training to operate .
*Note: 0.5-30 liter volume, we can supply other size according to customer requirement, too.
P84(pi-polyimide) is a filter material with the properties of flame resistance, high temperature resistance. Polyimide will keep a good performance when the temperature up to 240 degree centigrade, instant can up to 260 degree to 300 degree. Polyimide is leaf-shaped structure with a larger filter surface, and always embeded in the surface of other needle felt with different material to improve the filter efficiency.
For the properties of high temperature resistant filter material, good chemical resistance, good air
Permeability, high filtration efficiency, mostly applied in cement kiln, asphalt,
Waster incinerator, coal boilers, etc.
We offer polypropylene needle felt filter cloth.

Aramid needle punched felt can be operated in high temperature area while maintaining high strength, fire-resistant material. With a good dimensional stability and abrasion resistance ability, aramid filter fabrics have excellent dust release properties and resist attacks from many chemicals found in industrial smoke and fumes, but we suggest seldom to use them in the wet and acid circumstance.

PP needle punched filter felt has more advantages when compared with PET needle felt. It is acid and alkali resistant, and has low intenerate point. So PP needle punched felt are often used in liquid-solid separation field to equip with frame press filter, vacuum filter, bag filter centrifuge and other separating facility at below 100 centigrade.
We can change the normal PP needle felt performance by finishing treatment such as singe, calendar, heat set, coat and membrane.
Note: The weight (300~650 grams) and width (within 2.3 meters) can be customized! We can finish them with singeing, calendering, heat setting, Teflon coating and membrane.
There are two types of this kind of bags, one is made by aluminum foil, the other is made by VMPET.
Its multilayer structure can protect the product in it from damage caused by static, electromagnetic interference and moisture. Also it can be vacumized.
Normally it is used to package machines, electronic components, telecommunication equipments. Trade marks, symbols and pictures can be printed on it.
The inner and outer layers both can be made with a surface resistance of 108 - 1011 Ohm.
All sizes with flat openning, ziplock, and tridimensionals are available.
Its structure is normally APET/CPP. The thickness can be from 2 to 8 mils. It can keep components sensitive to static away from the potential static damage. In addition, it is semi-transparent, so the goods can be easily recognized from outside.
Trade marks, symbols and pictures can be printed on it if needed. The inner and outer surface resistance is 108 - 1011 Ohm.
Tianyuan mesh filter bags are constructed of quality monofialment meshes. As a woven fabric, monofilament mesh resists abrasion and a wide range of chemicals. It is unaffected by metal corrosion and has a high tensile strength and no fiber migration. Tianyuan monofilament mesh has uniform mesh opening which ensures the precision filtration of the filter bags. Besides monofilament mesh bag, we also provide multifilament mesh bag.
Material
Nylon (polyamide) or polyester monofilament / multifilament mesh
For versatile filtration systems such as high flow multi-bag pressure vessels, filter bags both in polyester and polypropylene execution are available on stock. The fibers may be of the woven or non-woven variety while the fabric opening ranges from 1-200 microns.
Our range of centrifuge filter bags are used as basket type as well as lifting type star filter bags. The most popular material for centrifuge filter bag are polypropylene and cotton . Woven fabrics of weight ranging between 500gms to 900 gms are used for making centrifuge bags depending on process requirements. We have best manufacturing facility and expertise to create this centrifuge very quickly

Water and oil proof filter bags are widely used under the occasion of larger moisture content. Comparing with other filter bag, the usage life and dedusting cycle time could be extended because of the non-adherence to the bag. The passing gas volume is also increased, so that it can save the energy, maintenance cost and increases the output.
