Review on METROVAC Computer/Electronics Duster, 4 inW, 70 cfm, Upgraded 2016 Version by Joe Olson

This "ESD" model is actually grounded and to my surprise the plastic tips are actually conductive plastic. I will explain why this is important for electronics. The Metro ED500 DataVac (White) is similar but does not have a ground connection and does not come with a wrist strap. I can't confirm if attachments are conductive. So you're basically paying an extra $25 for a ground wire, wrist strap, cooler color, and potentially conductive fasteners. But of course MetroVac has given serious thought to how to make this electrostatic discharge safe. It's not just a trick. Just to let people know what you get with "ESD protection" you don't use a vacuum to dust electronics because the incoming air is unfiltered and the moving particles create static electricity which then creates ESD can components. Instead use a blower as it will spread the dust in all directions. It's messy, but it prevents electrostatic discharge. The fan itself has an air filter, but the tips are not only grounded, they are conductive and connected to ground. This dissipates static charges that may have built up in the plastic. For example, ESD bags are simply conductive plastic bags and work in a similar way. Although in reality it connects you to the earth. To put things in perspective, this blower is powerful enough to be a moderate blower at waist height. This is quoted at 70 cfm and the leaf blowers are around 350 cfm. The grip is surprisingly comfortable and very light. It is relatively large compared to a compressed air tank, but so light that it is not difficult to hold. I thought the switch might be very awkward to press, but it's pretty easy. It's just fiddly enough that I'll probably use my other hand to turn it on and off occasionally. The length of the cable is quite good, even if it is not very noticeable in the photos. moderately hot. Maybe around 150F? Although this is fairly typical for engines. Again not shown in the pictures, maybe this was changed in the middle of the model? But it does have an unpainted grounding tab, which is one of the screws holding the case together. You can attach a wrist strap to it, but I plan to buy a detachable eyelet for it. It's worth the money considering compressed air is typically $5 a can and you'll spend about a can to clean a computer.
