Filtermakers Australia Pty Ltd 3 & 4 Peaked Deep Bed Bag Filters are available in the range of G3 to F5 ratings. Designed for use in most commercial or industrial HVAC systems, the FMDB 3 & 4 Peaked Bag are a widely used 
industry standard.
Our gusset supported pockets provide excellent inflation properties critical to HVAC Systems. Other non-gusseted style bags collapse easily and do not fully inflate or utilize their full surface area, which can cause airflow issues and greatly reduce the filter and equipment life spans.
The FMDB bags are made from the highest quality, premium 100% polyester synthetic media, which is moisture resistant and designed to remove and reduce airborne contaminants in the HVAC environment.
The FMDB filter range is made to the highest standards at our manufacturing facilities in Kilsyth utilising Australian made media.
All of our disposable bag filters meet or exceed the current Australian Standards and have been tested in accordance with AS1324.2 and ASHRAE 52.2.
Custom made bag filters can be easily and quickly manufactured if a sample, or detailed drawings can be provided. (Our Factory is Your Factory)
Utilising High Efficiency Media with excellent depth filtration, the FMDB provides High Efficiency Filtration with minimal initial resistance.
