Bosch 300 CFM Dust Extractor GAS20-17AH News & Opinion

Bosch 300 CFM Dust Extractor GAS20-17AH

The new Bosch 300 CFM dust extractor is coming and the major talking point is, well, it’s a 300 CFM dust extractor with automatic filter cleaning! Suction power at this level opens the door to a couple of possibilities you won’t approach with a standard vacuum.


10-Second Summary

  • Model Bosch GAS20-17A
  • HEPA and OHSA Table 1-compliant
  • 300 CFM
  • 17.5-amp motor requires a 20-amp, 120V circuit
  • $1499

First of all, 300 CFM gives you the ability to run 9-inch grinders on concrete with room to spare and the 17-gallon capacity will let you work for a long period before emptying. Remember that you need 25 CFM for every inch of grinder wheel under OSHA’s silica dust regulations.

What it also opens up is the ability to split the suction with a Y-connector and use two tools at once. Pulling out the grinder example again, you can two guys wrapping up concrete surface prep with a pair of 5-inch grinders and get the job done faster.

Pulling this kind of air comes at a power cost, though. The Bosch 300 CFM dust extractor requires 17.5 amps to run – so you’ll need to be on a 20-amp circuit. Bosch intends for this model to work on commercial and industrial sites, so that shouldn’t be a major problem.

Expect retail prices to set in at $1499 – about $150 less than Hilti’s 300 CFM model.
