Polyester is one of the most economical low temp filter bag medias used in the dust collection industry because of its reliable performance in a broad range of applications and availability. This media is used in industries including food manufacturing, woodworking, metalworking, building products, and energy. Polyester is one option if you are continuously operating between ambient - 275 degrees Fahrenheit, and have less than 10% moisture.
Filter bag is the most important part in dust collector which influences the collection efficiency and working temperature.
Renewal of bags creates major cost in maintaining bag house, so the lifetime of bags are the main factor affecting the cost and working condition of bag-house.
There are three types: woven fabric dust bag, non-woven fabric bag and compound filter material.
Three shapes: round type, flat type and customized type
Filtering method: inner filtering & outer filtering
Feature
1.The filter cloth is based on the thickness of the whole filter layer and belongs to deep filtration
2. the depth of the whole filter layer is formed from the fiber into a three-dimensional porous structure, from the inside and outside to the outside
Dense, forming gradient filtering
3. high pollution capacity, long filtration life, low pressure difference
4.Repeated cleaning, economic benefits
Application
1) The fume and smoke treatment and particle removing system in metallurgy plant, alloy plant, steel works, moulding factories, fire-retardant factories and power stations
2) Fume filtration, tiny particle recycle and division of liquid and solid in aluminum electro analysis, tin, zinc, cooper and other rare metals
3) Smoke filtration in garbage burning, coal-feed boiler and liquidized laid boilers
4) Division of liquid, solid and tiny particle recycle in chemicals, coke, carbon, dyestuff, pharmacy and plastics
5) Asphalt concrete mixture, cements, ceramics, building materials, lime and plaster
6) Dust treatment, purification and collection in electronics, mining, foodstuff processing, flour and timber processing.
