BAG FILTER

We manufacture and provide Bag Filter, ensuring efficient dust collection and air filtration solutions for industrial applications

A bag filter removes dust and particulate matter from industrial gas streams using fabric filter bags, ensuring clean air emission, environmental compliance, and efficient filtration in various industrial applications.

Bag Filters are vital for controlling industrial air pollution and ensuring cleaner emissions. Their
effectiveness, adaptability, and efficiency make them an integral part of environmental compliance and operational efficiency across various industries.

Bag Filter

A Bag Filter is an essential air pollution control device used in industrial applications to capture and remove dust, particulate matter, and contaminants from air or gas streams. It plays a crucial role in ensuring regulatory compliance with environmental standards while improving workplace air quality.

Types of Bag Filters

1. Pulse Jet Bag Filter – Uses compressed air pulses to clean the filter bags efficiently, widely used in cement, power plants, and chemical industries.
2. Reverse Air Bag Filter – Uses reverse airflow to clean the bags, suitable for high-temperature and large-scale industrial applications.
3. Shaker Bag Filter – Uses mechanical shaking to remove dust from the filter bags, ideal for small- scale and batch operations.

Applications in Industry

  • Power Plants – Captures fly ash and fine particles from flue gases.
  • Cement Industry – Controls emissions from kilns, crushers, and grinding units.
  • Steel & Metallurgical Industry – Removes dust and fumes from furnaces and material handling units.
  • Pharmaceutical & Chemical Industry – Ensures clean air in production and processing units.
  • Food Processing Industry – Helps in maintaining hygiene by filtering airborne particles.

Benefits of Bag Filters

  • High Filtration Efficiency – Removes up to 99.9% of dust and particulates.
  • Environmentally Friendly – Helps industries comply with air pollution norms.
  • Energy Efficient – Modern pulse jet systems optimize airflow and energy consumption.
  • Customizable Design – This can be designed for various industrial applications and dust loads.
  • Durability – Long service life with proper maintenance and high-quality filter media.

Materials Used

  • Polyester, Polypropylene – Common for standard applications.
  • Aramid (Nomex), PTFE (Teflon) – Used for high-temperature and chemically aggressive environments.
  • Fiberglass – Ideal for extreme heat and corrosive gas filtration.

Maintenance & Challenges

  • Filter Clogging – Regular cleaning and maintenance prevent pressure drop and efficiency loss.

  • Bag Wear &  Tear – Requires periodic replacement to maintain optimal performance.

  • Moisture &  Temperature Control – Prevents condensation-related damage and corrosion.
