Used Dust Collectors
As industrial manufacturers and users of heating and cooling systems continue to generate dust and pollution, one of the largest and most important industries today is air purification. To help keep our environment, work environments, and employees healthy, engineers have developed systems to removing contaminants from the air. Among these are dust collectors, which are popular and highly useful machines that purify air by pulling it in, trapping contaminants in a filter, and then allowing clean air to be released back into the environment. Dust collectors are not to be confused with air cleaners, which remove dust using disposable filters.

Applications of Used Dust Collectors
Used dust collectors can remove as diverse a variety of particles from the air as un-used dust collectors. Such particles include not only dust, but also fumes, smoke, and foreign airborne media, like metal shavings and wood shaving. They are great assets to workplaces and facilities that use machines that stir up and dispense liberal amounts of contaminants and irritants. Such environments are found in industries, including woodworking, building restoration (flood and fire), rubber and plastic processing, pharmaceutical production, and industrial machining. Quite commonly, for example, dust and fumes are created during brazing, welding, grinding, cutting, high speed machining, tempering, laser marking, and quenching.
Features of Used Dust Collectors
Parts of a used dust collector that may be refurbished, restored, or cleaned include motors, filters, suction arms, hoods, electric panels, and exhaust ducts. Most dust collectors, regardless of their exact design, some with an electric motor, which may be powered by a cord plugged into an outlet or by a battery or batteries. All dust collectors, by virtue of their function, have a filter. Filters are not all the same, and, upon request, suppliers can outfit new and used dust collector models alike with a number of different specific filter types, such as HEPA (high efficiency particulate) filters or fabric filters. The type of filter that is installed in a dust collector plays directly into the way it collects particles, as these particles are pulled in by the suction created by the motor.
Benefits of Using Used Dust Collectors
Dust collectors serve their customers by improving air breathability, removing odors from the air, creating a cleaner environment, and bettering the overall working conditions of employees present. They range in size and price, but many larger models can be quite expensive. For a less costly solution, consider used dust collectors. There are many reasons to look into used dust collectors, whether one is working within a small budget, looking for a deal, or purchasing a secondary system. Used dust collectors are just as handy as their new counterparts, as reputable suppliers always make sure they are refurbished, restored, and/or cleaned before resale. Often, they are in like-new condition, but, because they are pre-owned, they are sold at much lower prices.

Points to Consider When Purchasing a Used Duct Collector
Those shopping for used dust collectors may select from systems designed to focus on small areas or systems designed to tackle the air quality issues of an entire warehouse. Those interested in the purchase of a used dust collector are advised to discuss their needs at length with a knowledgeable supplier. Important factors to consider include the size of the space in need of air purification, the level of pollution to be addressed, and accessibility. This will help the supplier determine if a system needs to be small or large, permanent or portable, outlet powered or battery-powered, and so on.
In addition, the purchase of a dust collector, whether new or used, should always be based on the following factors: degree of dust collection required (quantified by the nature of the dust, the dust’s potential as public nuisance or health hazard, the dust’s salvage value, the plant location, and the allowed emission rates), dust concentration and particle size, characteristics of dust (concentration level and texture), characteristics of airstream (level of condensation, temperature, and chemical presence), and methods of disposal.
Customers should also make sure that they have a full understanding of how to care for their collection system. They should, for example, know how often the filter or the collection bag needs to be changed, as well as how to assemble and reassemble the device. Finally, those planning to purchase a set of used dust collectors must make sure that the supplier they choose has, if needed, updated their systems so that they comply with current OSHA and EPA standards.
