Filter bags for steel plants, baghouse by baghouse.
Steel plant baghouses handle hot, abrasive and sometimes spark-laden fume. Sinter plants often run fibreglass in reverse-air baghouses; EAF and BOF secondary dedusting usually runs polyester or aramid with spark protection; blast furnace cast houses need abrasion-resistant felt. Steel is one of Masturlal's core industries.
Media by baghouse
| Baghouse | Conditions | Media to evaluate |
|---|---|---|
| Sinter plant | Hot gas, fine dust, acid components | Fibreglass (reverse-air) or PPS |
| Blast furnace cast house | Abrasive dust, moderate heat | Polyester or aramid, heavier felt |
| EAF dedusting | Hot fume, sparks, fine dust | Polyester or aramid with spark arrestor |
| BOF secondary dedusting | Fine fume, temperature peaks | Aramid or P-84 |
| Stock house and material handling | Ambient, abrasive | Polyester |
This is a starting point. The final choice depends on measured temperature, moisture, gas chemistry and the cleaning system.
Things that shorten bag life here
- Sparks are the main cause of burn holes in EAF baghouses; a spark arrestor upstream matters as much as the media.
- Fine metal fume can blind standard felt; a smooth microfibre surface helps it release.
What Masturlal supplies

Questions, answered.
Which filter bags are used in steel plants?
It depends on the baghouse. See the table above: each location has a different temperature and dust, so different media.
Does Masturlal supply plants outside India?
Yes. About 30–35% of turnover is exports, mainly to the Middle East, Bangladesh and Southeast Asia, with installations in 40+ countries.
