Extreme Thermal Stability: The SENOTAY Fiberglass Filter Bag
Achieve flawless emissions control and exceptional cost-efficiency in extreme-heat industrial environments with the SENOTAY Fiberglass Filter Bag Series—the ultimate heavy-duty solution for high-temperature baghouses from Hebei OuTai Environmental Protection Equipment Co., Ltd. (SENOTAY). Woven from premium, alkali-free fiberglass yarn, these bags feature extraordinary dimensional stability and outstanding tensile strength (surpassing steel wire of the same diameter at a fraction of the weight).
Because pure glass filaments are susceptible to friction-induced self-abrasion, SENOTAY precision-treats every bag with specialized chemical finishes. This dramatically improves flex-life and protects the fibers during mechanical shaking or high-frequency pulse cleaning, making them a highly durable and cost-effective premier choice for heavy industrial processing.

Difference Between Woven vs. Non-Woven Fiberglass Filter Bags
Property | Woven Fiberglass | Non-Woven Fiberglass |
Structure | Interlaced yarns forming a stable weave. | Randomly bonded fibers (needle felt) |
Air Permeability | Lower (dense structure) | Higher (porous, flexible fabric) |
Mechanical Strength | Higher tensile and tear resistance | Good flexibility, less stiffness |
Dust Release | Easier due to smoother surface | Requires additional coating |
Common Use | High-temperature steady flow systems | Pulse cleaning and flexible housing systems |
Advantages of Fiberglass Filter Bags
· Excellent Heat Resistance – Operates continuously at 280°C with minimal shrinkage.
· Superior Filtration Efficiency – Up to 99.5% efficiency in particle capture.
· Chemical Durability – Withstands acids and oxidation gases.
· Low Energy Cleaning – Easier dust release reduces pulse energy demand.
· Non-hygroscopic – Does not absorb water or moisture.
· Extended Lifespan – Resistant to abrasion, maintaining stable performance for years.
