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 Air)
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 99.995% down to 0.3 microns.
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 where 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 99.995% @ 0.3 microns.
Chemical / gas filters
BOFA’s advanced carbon filters are designed to filter 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 airflow rates and the type, depth and surface area of the carbon used, taking into consideration the contaminants associated with the application and ensuring that appropriate dwell times are achieved.
Our filters have been developed to capture contaminants and odours, reducing the risk of bypass and/or tunnelling.
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 compact, cost effective and efficient solution, rather than having two separate filters.
