●Technical parameters

●Product Introduction
Antistatic Filter Bags are an industrial filter material with conductive properties. They are widely used in dust removal equipment in flammable and explosive dust environments, such as flour mills, coal powder plants, aluminum and magnesium processing, chemical plants, etc. Its main function is to prevent sparks caused by static electricity accumulation during dust removal and avoid dust explosion accidents.
●Common materials:
Polyester (polyester) needle felt + conductive fiber
Aramid (Nomex), PPS, PTFE and other high temperature resistant materials
Stainless steel conductive fiber or carbon fiber can be mixed
●Structural form:
Sewn bag structure (cylindrical type)
Pleated structure (star shape)
Surface treatment: singeing, calendering, laminating, water and oil repellent, etc.
●Advantages of antistatic filter bags
1. High explosion-proof safety
Conductive fibers (such as stainless steel wire or carbon fiber) are added to the filter bag to effectively guide the accumulated static electricity, prevent sparks from igniting dust, and ensure production safety.
2. High filtration efficiency
The filter bag is made of high-quality needle felt or coated material, with high filtration accuracy, can capture fine dust particles, and the emission can reach or even exceed the national environmental protection standards.
3. Strong wear resistance and chemical corrosion resistance
The material has excellent mechanical strength and acid, alkali, oil and solvent resistance, and is suitable for a variety of complex working conditions.
4. Adapt to a variety of working conditions
It can withstand high temperature (200~280°C), high humidity or corrosive gas environment, and is suitable for coal-fired boilers, cement plants, steel plants and other working conditions.
5. Long service life
The material has good toughness and is not easy to break. Combined with anti-sticking treatment, it can extend the service life and reduce the replacement frequency and maintenance cost.
●Applicable industry scenarios
Powder processing (flour, powdered sugar, starch, etc.)
Chemical production (paint, pigment, plastic additives)
Coal powder conveying and storage system
Metal grinding and polishing workshop
Cement and building materials industry
Pharmaceutical and food processing industry (must meet hygiene standards)

●FAQ:

Q.What is the filtration efficiency of the room temperature dust bag?
A.The filtration efficiency of the general needle felt material is more than 99%. If the coating technology (PTFE coating) is used, the efficiency can reach more than 99.9%, which is close to "zero emission".

Q.What are the common specifications of the room temperature dust bag?
A.Common diameter: Φ130mm, Φ160mm, Φ180mm, etc.
Length: Commonly 2m, 2.5m, 3m, can also be customized
Installation method: round mouth (steel ring type), spring ring, flange mouth, etc.

Q.What should be paid attention to during use?
A.Avoid excessive temperature to prevent bag burning
Regularly check whether the bag cage and filter bag are damaged
Avoid blockage caused by oily or sticky dust
Keep dry to prevent condensation and bag sticking
