Dust collectors are a class of air pollution control gadgets found in industrial or commercial environments that are designed to satisfy EPA and workplace air quality security requirements. They come in lots of shapes, sizes, and styles. The size of the dust collector will be figured out by a number of aspects, ultimately, the right-sized dust collector for any centre is the one that produces the required results.

Selecting a dust collector that is too large for a plant or facility is an obvious waste of resources – from its initial financial investment cost and area needed for installation to the continuous expenses of energy it takes in. On the other hand, too small of a system might conserve cash upfront on the preliminary investment, however, an improperly sized dust collector leads to costly inadequacies.

Our plumbers have worked with Sigrist Design on a recent build (which is what inspired this blog post). Sigrist Design was extremely helpful and we were pleasantly impressed with their ability to design a dust collection system customised for the client we were working with. With their considerate and collaborative communications, we would definitely recommend them again, and the school renovation project we worked on was a great success. Find them here.

Determining Your Dust Collector Requires

The type of dust, particle matter, and gases being produced within the centre will play a substantial role in identifying what kind of dust collector system works best for your facility and its size. More than likely you will be choosing from amongst four of the more common types of dust collectors – baghouse dust collectors such as the pulse jet or shaker systems, a cartridge dust collector, and a cyclone dust collector – depending on the commercial environment. Baghouse and cartridge-style designs are effective material filtering systems. The cyclone dust collector systems are utilized in combination with the cartridge, shaker, and pulse systems as a pre-cleaning system.

Particular types of dust require a baghouse collector, whereas other kinds of dust require a cartridge dust collector. Cartridge dust collectors are normally applied for fine, grainy dust and gases with effectiveness of 3 microns, whereas baghouse systems are more effective in collecting larger, sticky, or oily resin-like particle matter with efficiencies to approximately 5 microns.

Selecting The Right-Sized System

The size of the facility and the kind of dust, gases, and particulates created will play a huge part in the selection procedure. As soon as those dust collector requirements have actually been recognized, 3 primary factors will identify the appropriate size of the dust collector. Your engineer or team of engineers will require to determine air volume, air-to-cloth ratio, and interstitial velocity needed to satisfy the filtering needs of the centre.

Air Volume

Air volume is the quantity of air that passes through a dust collector when cleansing. That number is reliant on the residential or commercial properties of the dust and its attributes.

Air-to-Cloth Ratio

The air-to-cloth ratio refers to the volume of air that travels through one square foot of the filter media’s area. The homes of the dust being filtered will likely have a suggested air-to-cloth ratio to effectively filter the dust. For maximum effectiveness and filter life, the air-to-cloth ratio ought to be determined to the particular application conditions.


The interstitial speed of the air moving through the system likewise needs to be determined to figure out the right-sized collector. Interstitial speed determines the upward motion of air through the space in between the filter bags or cartridges and the dust collector. If the speed is expensive, the dust will be re-entrained back into the bag or cartridge causing incomplete cleansing, shortened bag or cartridge life, high-pressure drops in the system, and the waste in cost and excess, related to the application of compressed air.

Selecting the right-sized dust collector for your center is important for a clean, safe workplace, for keeping maintenance expenses down, improving production, and remaining compliant with national and local emissions policies. Calculating the CFM, air-to-cloth ratio and interstitial velocity will ensure that the right-sized dust collector performs as needed with the centre’s air quality at an optimum level.
