After reading this buyer’s guide, you will be well informed and ready to purchase the best device for your specific needs.
Types of Dust Collectors
In order to purchase the best dust collector for your specific needs, you first need to understand that there are different types of collectors, and that each one operates in a different manner and offers different benefits.
There are three main types of dust collectors, which include:
- The shaker bag house dust collector
- The pulse jet dust collector
- The reverse air bag house dust collector
Below, you will find a detailed description of each of these three types of dust collectors, including how they work, which will help you gain a better understanding of dust collection devices, and which one will work best for your needs.
The Shaker Bag House Dust Collector
This is the original dust collector. It collects dust on the inside of the filter bag. The housing typically consists of two or more compartments, and one compartment can be removed for cleaning while the other one continues to work. The filter bag hangs in vertical rows, and the bag tops are sealed closed. This allows them to be attached to the shaking mechanism across the width of the dust collector. The bottom of the bags are opened, and they are attached to a cell plate. Dirty air enters the bag house and is collected on the inside of the bag. The buildup of dust actually holds the bag open. The damper closes and the shaker mechanism moves, which creates a sine wave that starts at the top and moves down the length of the filter bag. The collected dust is then released and falls into the hopper below. Most of the dust is removed within the first five to 10 seconds of operation.
The Pulse Jet Bag House Dust Collector
The pulse jet bag house dust collector works by creating a pulse jet stream that usually operates at a five to 6:1 air to cloth ratio. The filter bags hang vertically inside the unit and they are held firmly in place by clamps, snap bands or other types of hold downs. The bags are supported by wire cages inside the system. The dust enters the system through an inlet and it is filtered through the bag. The dust is then deposited on the outside surface of the bag. The dust is removed by a big blast of compressed air, which is injected into the top of the opening of the filter bags. The air is provided by a blow pipe, which feeds over the filter bag. The blast of high pressure stops the normal flow of air through the filter. As the bag expands, the dust is released into the hopper.
The Reverse Air Bag House Dust Collector
In this type of dust collector, the dirty air flows from the inside of the bag to the outside, which actually means that the dust is collected on the inside of the filter bag. The filter bags are tubular in design, and opened at the bottom and connected to a tube sheet. The filter bags are supported from the top through a spring type suspension. The flow of air is reversed to being the cleaning.
Things to Consider When Purchasing a Dust Collector
There are a number of factors that you are going to want to take into consideration before you choose a dust collector to purchase. By taking these factors into consideration, you will be able to choose the best dust collector for your specific needs. Some of the most important things to consider include the size of the filter, the suction power and the cost of the unit. To learn more about these and other factors that we consider to be the most important when choosing a dust collector, please keep on reading.
What type of dust control do you need?
Dust collection needs can vary significantly, and they are unique to your specific situation. For example, you could be collecting dust that develops as a result of collecting wood chips, from spackle, or from welding. For this reason, it is very important to understand what your dust collection needs are, including the type of dust that you generate and the process that is used to create dust. For instance, is dust generated only when conditions are aggravated, or is dust always being generated? Also, is the dust only created a few hours a day, or is it created on a continuous basis. Also, how much dust do you create? Is it enough to require emptying the dust collector several times a day, or can you go a full day, a week, or even a month without needing to empty the device? Your answers to these questions will greatly determine what type of dust collector will work best for your specific needs.
The size of the filter
You also want to consider the size of the filter on the dust collector. You want to make sure that the filter can effectively pick up the dangerous dust particles that are infiltrating your space. The best dust collectors offer filters that have pleads in them. These pleads can filter particles as small as .3 microns, which will ensure that your air is fully cleaned.
The suction power of the dust collector
Another important factor to consider is the suction power of the dust collector. The last thing you want to do is purchase a device that doesn’t offer enough suction to remove the dust out of the air. The suction of a dust collector is measured by CFM, and you will need to calculate the amount of static pressure loss that will occur between your dust collector and where your tools are set up and operating.
Single stage or two stage?
You are also going to want to consider whether you should purchase a single stage or a two stage dust collector. Single stage collectors are less expensive than two stage collectors, however, they usually aren’t as effective as two stage collectors. A two stage dust collector first draws the air into a separator, which filters out the larger pieces. After that, the smaller pieces reach a filter, and they are removed. The benefit of this is that the largest particles will not clog the filter, which ensures that the filter suction is always working and that there won’t be any disruption in the collection process.
The durability of the dust collector
These devices do a tough job, and they are exposed to a lot of pollutants. As such, they need to be able to withstand a lot of wear and tear. The best dust collectors are highly durable and will be able to effectively rid the air of dust and contaminants and thoroughly purify it. You want to make sure that the dust collector offers every component that is needed to make it operational in one cohesive design. You also want to make sure that it is constructed of high quality materials that will last a long time.
What is in the dust?
You also want to make sure that you understand what is in the dust. Standard dust collectors are often efficient enough to remove most contaminant from the air and allow the air that is being pulled from the building to be returned; however, there are certain hazardous components that can impact the dust and the efficiency of the dust collector. For instance, chromates are hazardous and they require additional filtration in order to ensure that it can safely handle the dust and properly purify the air.
The size of the area
You should also consider the size of the area where the dust will be collected from, as this will impact the flow of air and the amount of dust in the air. You want to make sure that you purchase a dust collector that can properly clean the air in the space that you need the air to be cleared from.
You should also consider the installation of the dust collector. Usually, an HVAC technician will need to install the device; however, what is required for installation will impact the cost of installing the device, as well as the time it will take to install it.
Lastly, you are also going to want to consider the cost of the dust collector. These devices can vary significantly in price. Generally speaking, larger, more advanced models that offer more feature will have a higher price tag. Make sure you know how much you want to spend before you start shopping so you can avoid spending more than you are comfortable with.
The Features Dust Collectors Can Offer
Dust collectors can offer a number of features. These features are intended to make the dust collector more efficient and easier to use. As was mentioned above, the more features that a dust collector offers, the more expensive it will be. It is important to understand the features that are available so that you can determine if you want or need them, and if the added expense will be worth your while.
