WHAT’S THE DIFFERENCE BETWEEN BRUSHED AND BRUSHLESS MOTORS?
Brushless blower motors have a higher capacity to move air than brushed motors however do so with less static pressure. Static pressure can be thought of as suction and is measured in inches of water column (wc.). Thus a low suction unit will pull water perhaps 2 inches up a pipe and no more and thus would have a static pressure of 2″wc. High power brushless motors have a maximum measurement of 44″wc. This makes them ideal for applications with VOCs, odors and light loads of dust. Brushed motors on the other hand are measured at 90″wc and are ideally suited to conveying heavier smoke, heavier dust and any type of ‘sticky’ fume. Not only do the brushed motors have more static pressure but the filters tend to last longer as the motor can continue to ‘suck’ air through dirty filters that might otherwise reduce the airflow and require changing in a brushless unit. Brushed units are typically less expensive than the brushless units however they do require that the brushes be changed every 500-700 hours. This is a simple procedure that takes approximately 2 minutes and the only tool required is a screwdriver. Demonstration videos are provided for each of our products indicating how to perform this simple procedure. Since there are many advantages to both types of blower motors many of our units are available with either type as an option. If you have any questions or concerns about which type of blower motor is best suited for your application please call us at 1-800-626-0664 in North America or +1 514-421-0658 internationally to discuss it with one of our experts.
I contacted you via phone earlier today regarding an air filtration system. According to the head of our tech department this should be compatible with the Morntech (MT- L1290) that we have ordered. The specifications are listed in the right column of the chart below.
Our SPH-426 (SPH-400 series) was the perfect match for their Morntech (MT- L1290) laser cutting, laser engraving machine. Just to mention other brands of Laser cutters, Laser markers, Laser engravers- we’ve matched our Laser Fume, Dust, Odor Extractors with:
Our most popular unit for small to medium duty laser applications
Designed to fit into an application where direct capture from the source is possible
The SPH uses high power blower motors to pull the air through 3 stages of filtration consisting of a pre-filter for large particulate, a certified HEPA filter to capture 99.97% of all particulate greater than 0.3 micron and a chemical filter with up to 40 lbs. (18kg) of odour and VOC treatment
This unit is available in brushed and brushless versions
This unit has many options and can be customized for OEM applications
We offer single or dual inlet lids with multiple diameter inlets as well as extended lids with either top or bottom intakes for customers using these units under tables. In total we have 18 different lids, ask us about your application!
