Many years of designing and manufacturing fume extraction and filtration systems for a variety of industries has given BOFA the experience and knowledge to help ensure that their products are the best available on the market.
Their unique filtration systems are designed to meet or exceed airborne emissions standards and optimise productivity while lowering the overall cost of ownership.
The combination of pre-filtration systems and high efficiency particle filters enables BOFA extraction units to remove 99.995% of particles 0.3 micron in size. This ensures that clean air is maintained in the workplace, while patented innovations such as DeepPleat DUO coupled with reverse flow air technology, optimize filter lifetime and lower the overall cost of ownership.
PANEL PRE-FILTERS: 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 HELP. Most pre-filters have an efficiency grading of F5-F7. When plastics are being lasered, the particulate size generated is typically 0.2microns.At this level of filtration the media has efficiency of 35% in F5 to 65% in F7. When metals are being lasered the particulate size being generated is typical below 1 micron. This equates to an efficiency of 65% in F5 to 80% in F7.
The BOFA range of fume purification systems have an F8 grade media which gives an efficiency of 80% at 0.2 microns and 95% at 1 micron.
DeepPleat DUO PRE-FILTERS: Save filter life and money with BOFA's unique pre-filter. This patent protected DeepPleat DUO concept is designed around reverse flow operation to maximize filter life. As the contaminated air enters the filter chamber the velocity is dramatically reduced, allowing the larger particles to fall to the bottom and therefore clear of the filter media. The smaller, lighter particulate are then retained within the filter pleats. This allows a greater majority of the larger particulate to fall away from the filter surface and into the dropout chamber within the filter enclosure giving a far greater efficiency and much longer life for the full filter area.
Important Notice: Many factors beyond the control of BOFA can affect the use and performance of BOFA products in a particular application, including the conditions under which the product is used. Since these factors are uniquely within the user’s knowledge and control, it is essential the user evaluate the products to determine whether the product is fit for the particular purpose and suitable for the user’s application. All products, product specifications, availability and data are subject to change without notice, and may vary by region or country.
