Used Dust Collector equipment

Dust Collectors
Dust collectors are air cleansing equipment designed to improve commercial or industrial air quality by capturing particulate matter for proper disposal. Dust collectors are often used as air pollution control devices to filter pollutants and solid particles from being released into the air. Special Projects International offers several different types of dust collectors from well-known manufacturers such as Boedecker, Consolidated Engineering Co., Donaldson Torit, MAC, Mikro-Pulsair, Vac-U-Max, and more. Our wide range of types of dust collectors include: reverse pulse jet dust collectors, shaker type dust collectors, industrial air filters, cyclone separators, and bin vents. The different types of dust collectors we offer are listed and described below.

Reverse Pulse Jet Dust Collectors
Reverse pulse jet dust collectors are the most common type of industrial dust collector in our inventory. A pulse jet dust collector is a suction and filtration system. Dust-laden air is drawn into the machine where the air is cleaned by filter media that collects the dust. After the clean air is discharged from the collector, compressed air is applied in reverse pulse to clean the filter media. We offer a wide range of sizes of reverse pulse jet dust collectors to suit various processes.

Shaker Type Dust Collectors
Shaker type dust collectors are another common type of industrial air cleaning machines. These systems have cartridges or bags that collect the dust as uncleaned air is fed into the system. Once enough dust has formed on the bags, they are shaken, and the dust settles into a collection hopper. These systems can operate continuously and are available in several different sizes.

Industrial Air Filters
Industrial air filters are machines designed to remove solid particulates and molecular contaminants for the purpose of improving air quality in a system or environment. Contaminated air flows into the upstream side where contaminants are removed by a filter media. After passing through the filter, the clean air exits downstream leaving the contaminants in the filter media. Industrial air filters are used in numerous applications to keep debris, dirt, oil, and other contaminants out of the air.

Cyclone Separators
Cyclone separators work by feeding a gas into the cylindrical machine body where it winds around the inside circumference. As the gas travels down the inside of the machine, its path creates a vortex. This vortex within the machine leaves the unwanted particulates at the bottom or on the wall sides. As the heavier particulates accumulate on the outside of the vortex and are discharged through the bottom, the centrifugal action of the separator forces the light, clean gas upwards through the discharge. Some advantages of cyclone separators are that they are cheap, easy to maintain, have high efficiency, and do not use filters so they can run continuously without getting clogged. Cyclone separators are often used in sawmills, oil refineries, or in kitchen ventilation systems to separate the grease from exhaust air in extraction hoods.

Bin Vents
Bin vents are dust collection systems that function similarly to reverse pulse jet dust collectors and shaker type dust collectors. Dust-laden air enters the bin vent dust collector from the bottom and dust accumulates on the outer surface of the bag filter creating a surface cake. Then, using an electronic adjustable timer, a controlled pressure drop will remove the dust from the filter and send it towards the bottom discharge. These units usually do not include hoppers, but instead are mounted on top of silos, mixers, or other dust-generating pieces of equipment.
