The DD 3x8 industrial downdraft table features a five stage spark arrestance baffle system preventing sparks and slag from reaching the main filter cartridges. An integrated automatic reverse-pulse filter cleaning system reduces maintenance requirements by blowing particles into a dust tray for removal. The 3’ X 8’ Downdraft Table comes standard with 4 nanofiber filters capable of handling 99.8% of contaminants @ 0.5 micron along with exhaust duct mufflers to reduce the noise level. Downdraft tables can be mirrored together to create large work surfaces when dealing with large work pieces.
