As a project company in need of emission control solutions, choosing the correct dust collector is vital for both the safety of workers on-site and compliance with job site codes and regulations. In this blog, we will discuss the factors to consider when selecting the appropriate dust collector size for your job.
Protecting Your Workers
The primary purpose of a dust collector is to remove impurities from the air and improve air quality. This is crucial for worker safety on job sites where hazardous dust is present. While protective gear like blast helmets can provide some protection, proper ventilation is necessary to ensure worker safety.
Ventilation Requirements
The ventilation requirements for non-hazardous dust call for a horizontal air movement of 24m/minute. However, for hazardous dust, a higher airflow of 30m/minute is required. These requirements are used to calculate the correct dust collector size needed for the job.
Calculating the Correct Dust Collector Size
To calculate the correct dust collector size, you will need to multiply the cross-section area of the site by the required airspeed. It is essential to note that you should use metric units of measurement (meters and millimeters) for accurate calculations.
Let us take an example of a site measuring 5 meters by 5 meters with non-hazardous dust.
Multiply the length, width, and airspeed requirement: (5 m x 5 m x 24 m/minute = 600 cubic meters/minute.
Therefore, you would need a 600 cubic meters per minute dust collector for the 5m x 5m job site with non-hazardous dust.
If the same site had hazardous dust, the required airspeed would be 30m/minute, and you would need a 750 cubic meters dust collector (5 m x 5 m x 30 m/minute = 750 cubic meters/minute)
Conclusion
Selecting the correct dust collector size is crucial for the safety of workers and compliance with regulations. By calculating the correct size needed for your job, you can ensure that your workers are protected from hazardous dust, and your company remains compliant.
