Application of Circular Filter Inserts

An assessment of the problems associated with remote handling, changing, and disposal of filters suggests that significant advantages to filtration systems could be made by the adoption of high-efficiency particulate air filters with circular geometry for both new and existing ventilation plants. The circular filter development has considered filters for a range of flows from 45 to 3400 m³/h, for small gloveboxes to large-volume installations. The development has also concentrated on filter systems employing simple change techniques that take advantage of the circular geometry.
