Bag Filters provide deep-bed particulate capture for commercial,industrialand HVAC systems that handle higher dust volumes or extended operating cycles. For odour removal in the same system, see ourcarbon filtration units. Bag Filters are widely used as secondary filtration stages due to their large dust-holding capacity.

Why Bag Filters Matter

High dust-holding capacity:The extended surface area of Bag Filters allows them to retain larger quantities of particulate without compromising airflow, making them ideal for high-duty environments.Supports overall system efficiency:By capturing fine dust and particulates upstream, Bag Filters reduce load on fans, coils and downstream filters, lowering maintenance and improving energy efficiency.

How They Work

Multi-pocket design:Air passes through deep pockets of filtration media, increasing contact time and improving overall capture efficiency.Customisable performance:Bag Filters are available in multiple grades, allowing filtration levels to be matched to airflow volume, particulate size and site duty.
