More About HVAC Bag Filters
Our synthetic bag filters are manufactured in our UK factory for use in HVAC systems where filters with a high dust holding capacity, low-pressure drop and where long service life is required. Bag filters are ideal for use as a medium to high-efficiency final filter or as a prefilter to high-grade filters such as our HEPA filters.
Our bag filters are manufactured with media classification EN779:2002, with a choice of M5 55%, M6 65%, F7 85%, F8 95% and F9 >95%, in a corrosion-resistant galvanised steel frame. Fire testing according to DIN 53438-3 (F1) with a maximum operating temperature of 80°C.
Chose between all the standard sizes between 287 and 592mm, with a choice of pocket and header frame depth. All sizes are displayed as height x width, with the long side of the pocket being the height. Please select the relevant filter width to view the relevant variations.
Common questions about Bag Filters
What are bag filters used for?
Bag filters are widely used in various industries to remove particles and contaminants from air or liquid streams. They are designed to capture and retain dust, dirt, pollutants, and other impurities, thereby improving the quality of air or liquid. Common applications include industrial processes, HVAC systems, wastewater treatment, and many more. Bag filters are instrumental in maintaining clean and safe environments, protecting equipment, and ensuring compliance with environmental regulations.

How often should bag filters be changed?
The frequency of bag filter replacement depends on several factors, including the type of contaminants being filtered, the filter's design, and the specific application. In general, bag filters should be changed when they reach their capacity and can no longer effectively capture particles. Routine inspections and monitoring of pressure differentials across the filter can help determine when replacement is necessary. Some applications may require bag filters to be changed weekly, monthly, or even annually. It's crucial to follow manufacturer recommendations and conduct regular maintenance to optimize bag filter performance and lifespan.
What are the different types of bag filters?
Bag filters come in various types to suit different applications. Some common types include:
Standard Bag Filters: These are typically made of woven or felted fabric materials and are used for general dust and particle removal in HVAC systems, industrial processes, and pollution control.
High-Efficiency Bag Filters: These are designed with finer materials and advanced filtration technology to capture smaller particles, making them suitable for applications where stringent air quality standards must be met.
Liquid Bag Filters: These are used in liquid filtration applications to remove solids, contaminants, and impurities from water, chemicals, oils, and other liquids.
Pulse-Jet Bag Filters: These bag filters use a cleaning mechanism that involves periodic bursts of compressed air to dislodge accumulated particles, extending their lifespan and efficiency in high-dust environments.
Reverse-Air Bag Filters: These bag filters are ideal for applications with high temperatures and abrasive materials, using a reverse airflow for cleaning.
What is another name for a bag filter?
Another common term for a bag filter is "fabric filter." Bag filters are often referred to as fabric filters due to their construction using fabric or felted materials to capture particles from air or liquid streams. This terminology is frequently used in industrial and environmental contexts when discussing filtration equipment. So, "bag filter" and "fabric filter" can be used interchangeably to describe the same type of filtration system.
