Applications in Pharmaceutical Powder Recovery
Our triangular filter bags are specifically designed for use in:
- Dust collectors in tablet pressing, granulation, and blending operations.
- Hopper and bin vents to recover powder and prevent emissions.
- Vacuum conveying systems for sensitive pharmaceutical powders.
- Fluid bed dryers and other processing equipment requiring high-efficiency filtration.
The triangular shape fits perfectly into triangular or square housings, offering up to 30% more filter area compared to standard cylindrical bags of similar volume. This results in lower pressure drop, reduced energy consumption, and longer bag life. Additionally, the needle felt material provides a depth filtration mechanism, capturing fine particles even at high dust loads.

Frequently Asked Questions (FAQ)
-
What materials are available for the triangular filter bag?
We offer needle felt made from polyester, polypropylene, Nomex, and other specialty fibers. The choice depends on your operating temperature, chemical exposure, and required filtration efficiency. -
Can I get a custom size?
Yes, we manufacture triangular filter bags in any size to fit your equipment. Please provide the dimensions (length, width of each side, and cuff details) for a precise quote. -
What is the typical filtration precision?
Our bags can be made to filter particles from 1 micron up to 100 microns. For pharmaceutical powder recovery, we recommend precision between 1–10 microns for fine powders. -
How do I install the bag?
Installation is straightforward. The bag typically has a sewn cuff or elastic top that fits over the support grid. We can also add snap bands or grommets for secure mounting. -
Are these bags washable and reusable?
