Realistically, you’ll leave it on high most of the time. Sometimes you don’t need every CFM or inch of water lift available, so each of these dust extractors has a variable power control dial. Bosch comes in second with 7.5 amps available for a tool. Just be sure you’re connecting to a 20-amp breaker if you’re running that much. Hilti gives you the most potential with up to 11 amps available for a tool. All of these dust extractors have this feature. When you shut the tool down, the extractor runs for a few extra seconds and powers down. The advantage of running power through the dust extractor is that it senses when you turn the tool on and automatically kicks on the extractor. Considering that you need 25 CFM for every 1″ of grinder wheel diameter, you’re probably going to want separate power sources for most concrete applications to get the best dust collection possible.

Every one of our dust extractors has this feature, but the power of the tool you can connect varies widely. The extractor has an outlet that allows you to run a power tool and automatically turn the vacuum on and off when it senses power going to the tool. One of the benefits of going with a premium OSHA-compliant dust extractor is pass-through power. The potential downside to more frequent filter cleaning is that you lose some suction performance during the cycle. Metabo is also the only model to feature a cleaning-only mode to run through a cleaning cycle without kicking the vacuum on. When the extractor drops below a predefined performance level, Metabo’s auto cleaning system immediately vibrates the filter to clean it, regardless of where it is in its interval cycle. Once again, Metabo moves ahead with a suction performance sensor. Most of these models automatically clean every 15 seconds. When it comes to auto cleaning intervals, more frequently tends to be the way to go. But when it comes to reducing the amount of dust that reaches the air, it’s a superior design to the common reverse airflow systems. It’s not a simple innovation and adds to the cost of the dust extractor.

Metabo uses an electro-mechanical system that eliminates the escape and lowers the risk of filter damage. However, that can potentially create a release of dust or damage the filter over time. Most auto filter cleaning systems use a reverse airflow method for cleaning the filter. Just keep in mind you’ll need to grab a pair of HEPA filters to get started with your Makita dust extractor.Įditor’s Note: Bosch now ships with a HEPA filter for the same price as model VAC090AH.

Makita and Metabo both require (and ship with) 2 filters.

These 99.97% capture rate filters require a design that won’t allow 0.3-micron (or greater) particles to escape somewhere else on the machine!īosch, Hilti, and Makita both require you to grab your HEPA filters separately while Metabo, and Milwaukee all ship with them. It’s not as easy as just slapping the filter in any vacuum, though. To make sure you’re covered, we’re looking at HEPA-ready extractors only in this test. While the majority of applications don’t actually require a HEPA filter, it is a requirement in some cases. But not everyone needs to spend $1500 on their dust extractor, so back to the matter at hand. Given its twin-turbine design and CFM rating bordering on double what we see from these smaller models, I expect that it would dominate the field.

That size requirement actually eliminated the 2017 Pro Tool Innovation Awards winner for dust extractors the beastly Hilti 300 CFM VC 300-17X.

These dust extractors are still easily portable and have a decent amount of capacity to go along with it. Additionally, I limited the field to the medium size 8 – 12-gallon range. The group that we brought in certainly isn’t an exhaustive list of every OSHA-compliant dust extractor out there – it covers the most popular brands. We’ll look to revisit those when they hit the market in standalone reviews. When I started contacting manufacturers about our shootout right after the September 23rd deadline, I was surprised to find that several well-known names didn’t have theirs ready quite yet. In order to be fully compliant, your dust extractor needs to have a filter cleaning mechanism and a HEPA filter to be good across the board. In this head-to-head review, we’re looking for dust extractors that meet OSHA silica dust requirements for working in masonry applications. To answer that question, we have to look at several things, but the most important is the application.
