This is a great dust collector. All the right pieces for a great price... especially when you get free shipping. One thing I wanted to clear up is the difference between a dust collector and a shop vac. Typical Dust Collector (DC) static suction is about 8-12 inches of water. In other words, the dust collector can pull a static column of water about a foot high. The 50-850 is rated at 11.4", so its at the top of range. Nice! But DC's, as a whole, are meant to pull large volumes of air not large amounts of suction power. A typical tank style 2.5 hp shop vac can pull around 60 inches of water... much higher static suction power. But with air movement ratings at around 150 cfm, no where near the volume of air that a DC can. The 50-850 is rated at 1200 cfm. You can't beat a good DC for pulling and fltering a large volume of air. Great for planers, table saws etc. But don't expect to use them to vacuum the family minivan though they will do that too in a pinch. The Delta 50-850 is a great dust collector, good static vacuum, nice large volume of air, great price and quality from a reputable company... but don't throw away your shop vac.
