Bag Filter for Galvanizing Fumes

Bag Filter for Galvanizing Fumes

In any hot-dip galvanizing operation, managing zinc oxide fumes and particulate emissions is critical not only for regulatory compliance but also for the health and safety of plant personnel. The ANI Metal Bag Filter for Galvanizing Fumes is engineered to capture and contain airborne contaminants generated during zinc immersion and annealing processes, delivering a clean, safe working environment while safeguarding your equipment and surrounding community.

Why Bag Filters Are Essential in Galvanizing Plants

During a typical galvanizing cycle, molten zinc reacts with air to form zinc oxide fume, which can carry heavy metal particulates. Without proper filtration, these fumes:

• Obscure visibility and corrode nearby structures

• Exceed local emission limits, risking fines and shutdowns

• Expose operators to respiratory hazards

A purpose-built bag filter system removes up to 99.9 % of submicron particles, ensuring your galvanizing plant meets environmental regulations and plant safety standards.

Key Features of ANI Metal Bag Filters

High-Efficiency Filter Bags
Our filter media uses multi-layer polyester felt treated for high abrasion and chemical resistance, capturing fine zinc oxide while lasting longer than conventional fabrics.

Modular Cell Design
Scalable sections let you tailor capacity for batch-size, throughput, and future expansions without disrupting production.

Reverse-Pulse Cleaning
Automated pulse-jet system periodically dislodges accumulated dust, maintaining differential pressure below 250 Pa for consistent airflow.

Robust Housing & Ductwork
Heavy-gauge, acid-resistant steel construction withstands high-temperature galvanizing fumes and minimizes corrosion over years of service.

Integrated Emission Monitoring
Built-in sensors track particulate levels in real time, triggering alarms if concentrations approach preset thresholds.

Operational Benefits

• Improved Air Quality: Protect operators’ health with virtually dust-free air in work zones.

• Regulatory Compliance: Stay well under permit limits for particulate emissions and zinc oxide output.

• Extended Equipment Life: Remove corrosive particulates before they attack ventilation fans, ducting, and chimneys.

• Reduced Maintenance Costs: Self-cleaning pulses extend filter bag service intervals by up to 50 % compared to manual cleaning systems.

• Energy Savings: Low-pressure drop design cuts fan power consumption by as much as 20 %.

Maintenance & Environmental Compliance

Routine inspections and digital performance logs help plan scheduled shutdowns for filter replacement—minimizing unplanned downtime. The captured zinc oxide is conveniently collected in hoppers for recycling or safe disposal, turning waste into a potential revenue stream while meeting ISO 14001 environmental management standards.
