In the chemical and pharmaceutical industry, there are dusts which, due to their high value, are recycled into the production process. On recycling, it must be simultaneously ensured that the products are free of foreign substances and that the strict legal requirements in terms of product purity are maintained. All this demands filter media tailored perfectly to the individual requirements of the dust collector to meet the highest standards in filtration efficiency and product purity.
Typical Operating Conditions:
| Temperature: | Cont. (°C) | 20°C-250°C |
| Peak (°C) | Orientation to the maximum peak temperature of the fibre polymers used | |
| Dust: | Cosmetics, fertiliser, detergents, pharmaceuticals, pigments | |
| Dust Properties: | Abrasive, chemically aggressive, explosive, fine, coarse, sticky | |
| Dust Source: | Dryer, mills, mixers | |
| Harmful Gases: | H2O, NOx, volatile chemical substances | |
| Cleaning Process: | Pulse jet | |
| Fuels: | Natural gas, oil |
Specific Requirements for Filter Media in the Chemical and Pharmaceutical Industry:
- Discharge of electrostatic charges
- High abrasion resistance
- High separation efficiency
- Good chemical resistance
Scrim and Fibre Types for Filter Media in the Chemical and Pharmaceutical Industry:
Due to different operating conditions and compositions of the gas streams, almost the complete spectrum of needlona®-filter media from the low and high temperature range is used in the chemical and pharmaceutical industry. needlona®-filter media stand out for their excellent separation of the often valuable dusts and hence make a positive contribution in increasing the productivity of your production processes.
In environments in which explosive dust is present, we recommend the use of needlona®-filter media from our ExCharge®-product line. They dissipate electrostatic charges safely and achieve resistance values of well below than 106ohms. ExCharge® is certified by DEKRA-EXAM GmbH.
