Don’t be surprised if the dust collector that meets your static-pressure needs is rated at about double the cfm any of your machines requires. Manufacturers often rate cfm with no ducts attached, so their ratings are higher than you’ll get in real-world use. (To learn more, see our dust collector review from issue 140.)

Jan 16, 2005 · I would like some information on dust collection. I have been reading as much as I can about the subject and I have found myself perplexed about Static Pressure and dust collection systems. First, I understant that most duct collection units are rated for static pressure, and I am curious about how the reliability of these ratings

This determines if the dust collection system is running efficiently or if the system needs maintenance. When purchasing a fan or a blower, it will be rated for a certain amount of cubic feet per minute (CFM) at a given amount of static pressure. For example, the fan may be rated for 10,000 CFM at 11” of static pressure

The largest value you calculate for your system then represents the static pressure loss your dust collector must be able to overcome. Enter this figure on Worksheet 1. Worksheet 1 now shows the maximum CFM flow and static pressure loss for your system. To power your system, you’ll need a dust collector that meets or exceeds both figures

Jun 02, 2016 · Dust collection systems need to balance air volume (measured in cubic feet per minute or CFM) and velocity (feet per minute or FPM) and limit static pressure (SP). The air travelling through the ducts must maintain enough velocity to keep the dust and chips in the airstream—that’s 4,000 FPM in the branches and 3,500 FPM in the main line

A typical dust collector will have a media face velocity in the range of 0.5 to 12 feet per minute. By contrast, ASHRAE 52.2 tests airflow velocities in the 118 to 748 feet per minute range. That means the magnitudes are 10 to 1500 times higher in a MERV test than in a dust collector

In simple terms, static pressure determines how much resistance (“static pressure loss”) your dust collector can overcome in order to move a given volume of air through the hoses and pipes. When it comes to designing a dust collection system, the raw CFM figure is initially more important than the raw static pressure figure, though static

These blowers are only capable of pressures up to approximately 1 ½” static pressure water gauge. Static pressure is pressure, which is exerted against the walls of an air duct that is created by friction and impact of air as it moves. The average static pressure of most small dust collection systems is 8″ to 10″

Differential pressure is the difference in pressure from the dirty side (filter side or dirty air plenum) to the clean side (clean air plenum) of a dust collector. It is a measure of all resistances to airflow between the two chambers of the collector and typically includes the loss through the orifices of the tubesheet, the resistance of the

Differential pressure (also known as pressure drop, or Delta P) is a measurement of vacuum on two different sides on the dust collector (clean-air side and dirty-air side). On a negative pressure dust collector, dirty air is pulled by the system fan along the length of the ductwork into the dust collector and then through the filters before
