How do you calculate pressure drop in a bag filter?
The pressure loss across a strainer or filter can be calculated using the system’s flow rate and the Cv factor for that strainer or filter. For example, a 1 ” strainer with a Cv factor of 8 will have a 4 psi pressure loss in a system with a 16 gpm flow rate: (16 ÷ 8) 2 = 4.
How do you calculate CFM for dust collection?
For a rectangular port, calculate the area (multiply length times width, in inches). Then, multiply that area times 28 to find the approximate flow in CFM @ 4,000 feet per minute (FPM).
How many CFM is the Harbor Freight dust collector?
1550 CFM
How do I build a shop dust collection system?
- Step One: Layout the Machinery Of Your Shop.
- Step Two: Draw a Top-Down View Sketch (to Scale) Of Your Machines and Dust Collector.
- Step Three: Determine the Total CFM Required For Your Whole System.
- Step Four: On Your Drawing, Sketch Out The Position of Your Main Duct Line.
- Step Five: Determine The Size Of your Ducting.
How do you size a shop dust collector?
To determine flow capacity, measure the tool’s dust collection port. If it’s round, measure the diameter. For a rectangle, multiply the length by width, then multiply that number by 28 to find the flow of CFM at 4,000 feet per minute (fpm) airflow.
What is a good cfm for dust collector?
In general, the range for effective chip, shaving and large particle dust control is between 300 cfm for a tool with a lower dust and debris output, such as a scroll saw, and 900 cfm for a tool that really puts out the shavings, like a 24′ thickness planer.

How many HP dust collector do I need?
If you regularly operate more than one machine simultaneously, it would be wise to look at 3-hp or bigger dust collectors. The 2-hp machines are no noisier than the 11/2-hp collectors. They cost more, however.
Is 2HP dust collector enough?
No, I don’t think you need a bigger dust collector. A 2HP machine should offer at least 1,200 CFM of draw — plenty for connecting to your table saw, planer, jointer and lathe. So, yes, smooth-walled pipe (either metal or PVC) will increase airflow and dust collection efficiency. A larger main “trunk” line than a 4-in.
How does a shop dust collector work?
Dust collector systems work in general by drawing dust and particulates from the air through a filter that first captures and separates the matter, and then discharges purified air back into the workplace or environment.
How many Micron is a dust collector?
Most standard collectors filter a high percentage of 2 to 2.5 microns; but I’ve included one that even filters 86% of 1-micron dust particles. All of my picks separate dust particles from wood chips for more efficient debris packing and a clog-free filter.
What is the difference between a shop vac and a dust collector?
Simply put, vacuum systems are for precision cleaning and material conveyance, whereas a dust collector maintains breathable air and clean process air throughout an entire facility.
How long can dust collector hose be?
This type of collector works well with up to 15 feet of hose, but is still too small to serve a duct system connected to more than one tool at a time.
What is a 2 stage dust collector?
A two-stage dust collector consists of a first stage cyclone, a blower and a second stage after filter. A cyclone separator is a cone shaped vessel into which the dust-laden air enters. The blower then relays the fine dust to the after filter.
