This model is similar to the 3444B, but contains a larger fan and motor, along with our typical rails and tops found on our larger tables. There are no intake dust ports or vise due to these modifications. The 3444B Super comes with 80/20 cartridge filters which clean with a 99.95% capture rate at 0.5 micron. This model comes standard with casters, Denray's "Jet Pulse" push button cleaning, and a rubber coated top. This model does provide the option of a tilt out front edge as an add-on.
