A dust collection system is an accessory found in commercial and home woodworking shops used to collect wood dust, chips and shavings at the point of origin. Dust collection systems work on the same principle as central vacuum systems in homes: a fixed motor creates suction, which is distributed through the space via a network of rigid ducting and flexible hoses to the point of use. Suction can be further regulated with the use of blast gates.Smaller dust collection systems use a 'single-stage' vacuum unit to create suction and perform air filtration where the waste material is drawn into an impeller and deposited into a container (bag, barrel, canister, etc). Air is re circulated into the shop after passing through a filter to trap smaller particulate. Larger dust collection systems utilize a dual-stage (or two-stage) system, which separates larger particles from fine dust using a pre collection device (cyclone, baffled canister, etc) before drawing the air through the impeller. Air from these units can then be exhausted outdoors or filtered and re circulated back into the work space. Dust collection systems are often part of a larger air quality management program that also includes large airborne particle filtration units mounted to the ceiling of shop spaces and mask systems to be worn by workers. Air filtration units are designed to process large volumes of air to remove fine particles (2 to 10 micrometers) suspended in the air. Masks are available in a variety of forms, from simple cotton face masks to elaborate respirators with tanked air - the need for which is determined by the environment in which the worker is operating. Proper dust collection and air filtration is an important element in any work space. Repeated exposure to wood dust can cause chronic bronchitis, emphysema, "flu like" symptoms, and have more dangerous results decades after exposure such as cancer. Wood dust also frequently contains chemicals and fungi which can become airborne and lodged deeply in the lungs, causing illness and damage. A dust collection system for use in connection with a portable power tool is provided. The dust collection system generally includes a dust collection port having an intake that is interconnected to an air impeller by an intake duct. The impeller is driven by a motor, to create a vacuum at the intake port of the dust collection port. The outlet of the air impeller is in communication with a dust collection volume. In operation, the dust collection system is fixed to a portable power tool. Dust created during sawing or other operations is collected by the dust collection port, and is drawn away from the location at which the dust is created by a vacuum established by the air impeller at the intake port. The dust thus collected is deposited in the dust collection volume, which may include a filter bag. The present invention provides for the efficient collection of potentially harmful particulates created during sawing or other operations, without adversely affecting the portability of the portable tool to which the system is affixed.
