Given the 6' ducting, and required filters, the major and minor Dp's were calculated and compared to the available fan curves. This determined that the optimum setup was a single M6 fan with minimal other backpressure as seen below: | Given the 6' ducting, and required filters, the major and minor Dp's were calculated and compared to the available fan curves.

This system is designed to: a) reduce particulate entrapment in the fine particulate phase, b) ensure removal of particulate matter which is roughly similar to tobacco smoke as per literature on laser exhaust, and c) have sufficient residence time of the air in the carbon bed, while not increasing the overall dP of the filter system. | This system is designed to: a) reduce particulate entrapment in the fine particulate phase, b) ensure removal of particulate matter which is roughly similar to tobacco smoke as per literature on laser exhaust, and c) have sufficient residence time of the air in the carbon bed, while not increasing the overall dP of the filter system. | ||
