Follow N.R. Murphy's simple four-step system to evaluate dust collectors before purchase.

For decades, N.R. Murphy Limited has been a respected source of dust-collection systems across North America. But the company does more than supply great products; it serves as a collective of experts who advise customers on how to select the right system and use it at its peak effectiveness and efficiency. For example, N.R. Murphy offers a simple four-step guide on sizing up dust collectors before purchasing them.

List, location, and filter area

N.R. Murphy recommends to its customers that they take many factors into consideration when they determine the sizes and configurations of their new dust-collection systems. They should ask themselves the following questions: How many machines in the system produce dust? What is the pickup size of each one? What material will be collected, and at what weight? Which cleaning type is more suitable, shaker-style or continuous?

After these initial considerations comes N.R. Murphy’s four-step system. Step one: make a list of all dust-producing equipment. Identify these machines’ locations and calculate the total air volume that the system needs. Take the weight and flow characteristics of the collected material into account during this step.

Next, determine the location of the dust collector. Here, it is important to consider accessibility for installation and for waste-disposal vehicles, along with whether the collector will be outdoors or indoors. It is also wise to consult national fire safety codes for proper indoor size. After determining the location, it is wise to design the ducting layout, size the branch lines and main duct, and calculate the system static pressure.

Step three: determine the filter area that the system requires. This task involves knowing the correct air-to-cloth ratio, depending on the type and physical properties of the collected materials and the dust collector’s duty cycle. Finally, it is essential to find a reputable manufacturer – a company with the right expertise and the correct equipment for high-end dust-collection systems.

With more than 75 years of experience in providing the best industrial air-quality equipment on the market, N.R. Murphy knows how to help clients find the right solutions for their unique needs.
