DustControl Wings
Dust collection | How and why dust removal should be done in your pit.
Protect your employees and the environment.
Automatic system for controlling dust in pits.
Main advantages of the system:
- Completely automatic
- No electricity consumption
- No maintenance needed
- No maintenance needed
- Passed 100% of environmental inspections in Brazil
- Custom-made for each pit
- Completely below grate
- Pneumatic clean-out option when products shouldn’t be mixed
- Reduction in “shrink” (weight of dust expelled into the atmosphere)
How it works
For use in pits receiving: soybeans, corn, wheat, sugar, fertilizers, coffee and other bulk products
Pits and hoppers that receive bulk products have serious problems with dust emission, threatening the health of employees circulating in the area, creating conflicts with neighbors who are upset with dust in the air and just general pollution of the environment. All of these factors can lead to problems with local regulations and EPA inspectors that consequently lead to fines and legal costs. There is an easy and effective solution for controlling dust emissions in receiving pits and hoppers. Mechanical DustControl baffles are metallic modules installed below the pit grate that utilize the product itself to filter the dust as it is being expelled from the pit. The DustControl modules are only 15 to 20 inches deep (40-50 cm) with ducts that control the flow of the product into the pit, slightly slowing its velocity in order to maintain the ducts full of product. As the product is being unloaded, the modules first fill with product so that the dust-laden air being forced from the pit must pass through it. The product slows the velocity of the exiting air to the point that it can no longer carry the dust and it deposits the dust with the product. Essentially, the product is the dust filter. A second advantage is that the air leaving the pit at a reduced velocity does not create an airstream that captures the dust above the pit and disperses it through the atmosphere, but by being slowed down, allows the dust generated above the grate to settle into the pit. The DustControl baffles keep the dust with the product which reduces shrink, the weight loss that occurs when dust is separated from the product during transportation. One of our port facility clients calculated that this savings in shrink paid for the DustControl systems within a year. If desired, modules can be manually cleaned between unloading. For feed mills that cannot mix their products and have frequent product changes, Wings offers a pneumatic clean-out system that facilitates this process.
The DustControl is completely automatic without operators, and also maintenance-free. The first Mechanical DustControl systems, installed in 2003, are still working today without maintenance. DustControl works with almost all flowable bulk products including corn, soy, sugar, rice and fertilizers.
DustControl Plus
CONTROLLING EXCESSIVE AMOUNTS OF DUST
Mechanical DustControl + low-energy consumption filter = DustControl PLUS
• All the benefits of the Mechanical DustControl with a filter to capture dust above the pit grate.
• The filter removes dust separating from the product above the pit by creating a negative pressure below the grate.
• An added filter is a safety feature – it removes dust before entering your storage facilities.
• This reduces the risk of explosion. • Substitutes a large inefficient baghouse filter with a smaller filter (can be a preexisting filter)

Pneumatic Clean-Out
The DustControl Pneumatic Clean-out System is used to avoid mixing different types of grains during the unloading process. The DustControl is composed of metal modules with chutes and counter-weighted louvers that controls dust emission from receiving pits. As grain is unloaded into the hopper, it falls into the module chute and the weight of the product forces open the louver. At the end of unloading, the louver on each module closes and a small amount of grain remains in the chute. If it’s important that the chutes be completely free of product during a changeover, an employee can use a broom stick to manually open each louver to empty the chute. If you want to speed up the process, the Wings Pneumatic Clean-out System can be installed. A control box is mounted at a convenient location near the pit and air lines are connected to air cylinders mounted on each module. These cylinders are attached to drive bars that open and close the louvers when the operator pushes the button on the control box. This system needs a small air compressor.
At the end of unloading, when the quantity of product is not sufficient to maintain the louver open, this small amount of product remains in the module.
When the button on the control box is pushed, the air cylinder opens the louver to empty the module chute. The pneumatic clean-out system is ideal for pits that receive different types of products that should not be mixed, as is often the case in feed mills.
