Products Description
Polyester Fiber Anti Static Waterproof Dust Cartridge Shot Blasting.This air dust filter cartridge is manufactured with high-performance filter media, such as polyester fiber, cellulose, or PTFE membrane, and incorporates advanced pleating technology and structural design. It is specifically engineered for industrial dust collection, ventilation systems, and air purification equipment. Its primary function is to efficiently capture particulate matter, fumes, microorganisms, and other airborne contaminants, ensuring exhaust gas complies with environmental regulations while protecting downstream machinery and personnel health.Polyester Fiber Anti Static Waterproof Dust Cartridge Shot Blasting.
Product Features
High Filtration Efficiency: Exhibits excellent capture capability for micron- and submicron-sized dust particles, achieving filtration efficiency above 99.9% to meet stringent emission standards.
Low Operating Resistance: Optimized pleat spacing and breathable design minimize pressure drop while maintaining efficiency, significantly reducing fan energy consumption.
Large Dust-Holding Capacity: The pleated structure substantially increases effective filtration area, extending service intervals and reducing replacement frequency.
Temperature and Corrosion Resistance: Available in heat-resistant or chemically resistant media options, suitable for high-temperature flue gas or acidic/alkaline environments.
Excellent Pulse-Jet Cleaning Performance: Compatible with pulse-jet systems, allowing easy release of dust from the cartridge surface, ensuring strong regeneration capability and long-term stable operation.
Convenient Installation and Maintenance: Standardized interface designs fit mainstream dust collector models, enabling quick mounting and dismounting with short maintenance downtime.

Service Life
The service life of the filter cartridge is significantly influenced by operating conditions (dust concentration, temperature, humidity, particle characteristics), cleaning methods, and maintenance frequency. Under normal operation and with regular maintenance, the typical service life ranges from 6 to 24 months. Proper adjustment of pulse-jet cleaning parameters, avoidance of overtemperature operation, and periodic seal integrity checks can effectively prolong the replacement cycle.
FAQ
Q1: What filtration efficiency can your cartridge achieve? Does it meet emission standards?
A: Our cartridges offer ≥ 99.9% efficiency for particles ≥ 0.5 µm, with outlet emission concentration stably controlled at ≤ 10 mg/Nm³. This fully complies with current national and local environmental regulations, and in some regions, meets ultra-low emission requirements.
Q2: Can the cartridge handle high-temperature or corrosive conditions?
A: Yes. We offer multiple media options: standard polyester for ≤ 80℃, and high-temperature fiberglass or PTFE-membrane materials for ≤ 200℃ (peak 240℃). For acidic, alkaline, or oily dust, we provide corrosion-resistant and oil/water-repellent treatments. Final selection depends on your specific operating conditions.
Q3: The pressure drop across my cartridge rises too quickly. Why and how to fix it?
A: Rapid pressure drop increase is typically caused by high dust loading, insufficient cleaning pressure, improper pulse timing, or mismatched media. We recommend checking pulse valve performance, shortening the interval or raising cleaning pressure, and verifying inlet dust concentration against design values. We can also re-evaluate and recommend a more suitable media grade based on your actual conditions.
Q4: How long is the normal service life? Is replacement costly?
A: Under normal operation and regular maintenance, service life typically ranges from 6 to 24 months, depending on dust characteristics, temperature, and cleaning efficiency. Our cartridges feature high dust-holding capacity, offering extended service intervals and competitive total operating costs (including energy and labor) within the industry.
