When choosing a DC, consider the following parameters:
Power. The higher the power, the bigger particles the unit can suck in. for industrial models, this indicator starts at 1.5 kW, but don’t worry about the noise. Modern dust collectors are relatively quiet. The soft-start system, which reduces engine wear, is a good solution.
Class. L Class means the device can work with chalk, gypsum, and lime dust. M Class means the device collects larger concrete and wood dust. H Class means high power models that can handle all types of dust, including carcinogenic asbestos dust. ATEX models are universal vacuum cleaners, sucking even explosive sawdust and chips.
There’s a good reason to buy devices that can be used for wet and dry cleaning. But there is no need to overpay for a brand – almost all modern devices are durable and reliable enough.
