Review on POWERTEC 70283 4 Inch Collection Nozzle by Sean Perry

I recently switched from a 2" hose vacuum to a real DC 4" hose vacuum. Not having room for both, I upgraded the nozzle and floor nozzle to 4 inch versions, which are surprisingly hard to come by. That works great. It's like running a fire hose over the old ones, but it moves a lot more air and picks up dust from places the 2-inch version couldn't touch. I use it on both the handle for the top of the workbench and the bottom. - Standing equipment and attached to a stick for use on the ground. The bristles on the edges prevent sticking to surfaces and seal the hose. I tried another brush head that didn't have bristles and it just stuck to a flat surface blocking airflow. It has never had such a problem. I'd love to see more 4" accessory options (crevice tool, anyone?), but until then, this is highly recommended. (Why not just use an adapter? Try this. The dust collector has high static pressure and low air volume, while the dust collector has large air volume and low static pressure. With 4" hoses and accessories, it's better than a shop vacuum . C adapter and 2 inch accessories, the new dust collector is not as powerful as a shop vacuum cleaner.)
