Asphalt batching Site Bag Filter Nomex Filter Bag With Filter Cage supported
ECOGRACE Nomex / Aramid filter bag : Continuous operating temperature is up to 204°C, instant service temperature is up to 210°C, F ire retardant performance is excellent, Corrosion resistance and alkali resistance is good, Excellent thermal stability, excellent abrasion resistance and flexural resistance.
Aramid Filter Bag are mainly used in cement industry, asphalt batching industry,
metallurgical industry and tobacco industry for flue gas purification.
Nomex filter bag with PTFE membrane : puts PTFE membrane bonding to the surface of thermoplastic fiber filter material, plays the role of early powder layer to achieve surface of filter material. The membrane surface is smooth, with excellent chemical stability and good cleaning effect, greatly improving the service life of filter materils.

1. How to choose the right filter bag ?
Every filter media has its own characteristics and parameters, when we choose filter material for dust collector system , we need to know the following parameters :
(1) Working temperature ( Continuous working temperature / Instant Max temperature )
(2) Dust / ash particle
(3) Gas chemical composition
(4) Working pressure , filter velosity
(5) Emission concentration
2.How to assure the product quality of dust filter bag ?
We ‘d like to get and testing your sample and make sample accord to your sample and send to you for your checking . We will provide our sample for free if the sample price less than USD 30 .00 .
3.How many times can I clean and reuse a filter bag?
Filter bags are designed for one time use. Attempting to clean a bag will stretch the material. Maybe some holes will get bigger and allow dust to get through. In our company, most of the fiber is imported, we use the best raw material to ensure the quality of filter bags. Normally we can offer 2 years, 3years, 4years bags life time and even longer by your requirements.
4.Do you offer volume / distributor discounts?
Yes, we do offer volume discounts, and certainly that is based on the quantities and frequency of orders. Please feel free contact us if you want volume discounts and we will gladly offer you more details.
5.What shipments are available?
Normally, we ship goods by sea,air or express. Special requirement can also be acceptable.
