Manufacturing Filter bags at Hongyuan Envirotech

Fiberglass Baghouse Filter Bags are crafted from a robust and compact technical material that has been widely employed in the air filtration sector for a significant period. These bags deliver exceptional results in environments with elevated temperatures, reaching a maximum of 500°F (260°C), and can even endure sudden temperature spikes up to 550°F (290°C). In terms of chemical resistance, fiberglass possesses a moderate level compared to alternative filter media materials. While fiberglass filter bags exhibit impressive tensile strength, they are susceptible to damage from pulsating flex abrasion. However, this issue can be resolved by incorporating a 20-wire cage.

The fiberglass filter bag is a filter material that can withstand high temperatures and has a strong structure and exceptional performance. This product has a high level of porosity and allows gas to pass through with minimal resistance, making it an efficient and fast-acting filter material for high temperatures.
