BOFA Replacement Filters

Many years of designing and manufacturing fume extraction and filtration systems for a variety of industries has given BOFA the experience and expertise to ensure that our product solutions are the best available on the market.

Their understanding of industrial processes and applications are reflected in the design and manufacturing procedures applied to our range of standard, inline and patented filters.

Their unique filtration systems are designed to meet or exceed airborne emissions standards and optimise productivity while lowering the overall cost of ownership.

Pre filters

The pre filter is designed as a barrier, to capture the larger dust and particulate, protecting the HEPA filter from premature blocking.

BOFA offer a range of pre filters, all designed for different applications and processes, depending on the amount of dust being extracted.

The efficiency of the pre filter is directly related to the life of the HEPA in that the more particulates captured in it, the less can pass through and prematurely block the HEPA. Most pre filters have an efficiency grading of F5 - F7.

HEPA filters (High Efficiency Particulate Arresting)

HEPA filters used by BOFA are of the mini pleat design. They are generally manufactured by specialist filter companies to ensure that the latest manufacturing and test methods are adopted. Each filter incorporates a series of webbing between the pleats. This feature not only guarantees even spacing for full filter coverage between each pleat, but also alleviates the possibility of airflow vibration or collapse.

Filters should be individually tested and certified to a minimum efficiency of 99.997% down to 0.3 microns and 95% as small as 0.1 micron.

The BOFA ADVANTAGE micro filters are positioned within the system in such a way that all the particulates are not only captured but held within the media.

This is not the case with conventional reverse airflow systems were particulate can fall away and rest on the outside of the pre filter creating a health risk on filter replacement.

Mini pleats can be produced with depths of up to 200mm within each pleat, depending on the application.

BOFA HEPA filters are tested to filter 99.997% @ 0.3 microns.

Chemical/Gas filters

Assured safe capture and removal of hazardous fumes.

BOFA’s advanced carbon filters assures the safe capture and removal of hazardous fumes, with specific carbon types matched carefully to industry applications.

Contaminated air must remain in contact with the carbon bed for a period of time sufficient to ensure that no contaminants or odours are emitted (‘dwell time’). Our product designs consider the balance between air flow rates and the type, depth and surface area of the carbon used to ensure suitability for the contaminants associated with the application and to ensure that appropriate dwell times are achieved.

Our filters have been developed to capture all contaminants and odours, eliminating the risk of bypass and/or tunnelling.
Chemical-Gas filters

Advanced carbon filter (ACF) technology

BOFA’s combined filters are a combination of a HEPA filter and a chemical/gas filter coupled together to create a more compact, cheaper and more effective solution. This joint filter method extends across most of the BOFA products creating a safer, cleaner system.
