The size of your pulse jet bag filtration system will depend on the design you select.
You can follow the steps below to determine the most appropriate size of your filters.
You should consult experienced professionals to work out the expected minimum conveying velocity for the process gas and dust you will be handling.
Different particle contaminants have different conveying velocity.
Usually, the conveying velocity will vary between 3,500 to 5,000 ft/m for most materials.
Identify the primary sources which need constant venting and filtration when the application is running.
Also, count the secondary sources and note how frequently do they require venting.
This step will help you know how many vents you need to install in the workplace.
It also enables you to determine the quantity of airflow expected.
Calculate the quantity of CFM you require at each branch of your system.
You should consult a dust collection expert experienced with similar applications.
Consult the OEM for determining CFC of large sources like furnace, kilns, or for custom made equipment.
Draw a floor plan indicating the positions of all materials and devices. Connect the pieces in a sketch up to the filter.
Work out the required CFC where two primary branches meet by combining the CFC for each branch at the required velocity.
Static resistance is the resistance created due to friction arising from airflow through the system.
You should add the SP of the following elements to come up with a total SP.
The worst branch/ branch with highest SP
Main trunk line SP
The static pressure of main dust collector including any pre-filter
Introducing the Sinter-plate Filter Board Surface Air Filter, a groundbreaking innovation in dust collection systems. Crafted from rigid PE sintering material as its core, this filter is enhanced with a PTFE coating, delivering exceptional surface air filtering capabilities.
