MITER SAW DUST COLLECTION SERIES

For example, Grizzly Industrial advertises its G1029Z2P 2-hp collector as having 1,550 cfm at 11” of static pressure.īefore buying a small-shop collector, it’s a good idea to visit Air Handling System’s website and Oneida’s ductwork tutorial at One should also take a look at Bill Pentz’s extraordinarily informative site (which will answer just about any technical questions you might have. This “resistance” is measured in static pressure loss and dust collectors are often rated using this number. Because of these anomalies, there is a loss of efficiency. Some of these parts are curved, some are vertical and others are made of differing materials (plastic, metal, etc.).

Most of us will rely on the collector’s manufacturer to tell us that number, as measuring it is a bit of a challenge unless one has an engineering bent and access to an anemometer or a similar gauge.Ī dust collection system is a series of parts assembled together to create a whole. It doesn’t completely solve the problem, but it does help quite a lot by dislodging compacted sawdust.Īir Handling Systems, which designs and sells ductwork and collectors, recommends that the velocity of the air should be about 4,000 feet per minute (fpm) in branch ductwork between the machines and the main duct, and a minimum of 3,500 fpm in the main duct. In our shop, we added an air hose fitting to the side of one saw, so we can blow compressed air into the housing as the vacuum is running (see photo).

The cabinet just fills up and needs to be emptied on a regular basis. Most saws are pretty awful in this regard. The theory behind the lower hose is that the inside of the cabinet acts as a plenum, creating a vortex that keeps dust airborne long enough to enter the hose and be carried away. Table saw dust collection on a cabinet saw is generally run though a hose connected to the side of the cabinet, but adding an overarm chute that also collects above the blade will dramatically improve dust control.
