- Applicable for a variety of metals
- Downdraft collects particles and fumes transferring them through a filter system to clean the air
- Easier to clean
- More versatile, if you desire expanding your production by extending the table, it is easier to do so with a downdraft
- Best applicable for cutting mild steel
- Particles or fumes are pushed into the water so none remain in atmosphere
- Less expensive to install and operate because there's no need for a filter or a fume collector
- Filter must be changed regularly
- Occasionally different filters for different applications.
- More time consuming when removing or adjusting certain parts on the table, having to wait for them to be cool enough to handle with gloves or tongs
- Water must be added on a regular basis along with chemicals to prevent algae growth
- Must also be drained periodically and legally disposed of
- When cutting aluminum, hydrogen bubbles can build up under the aluminum plate from the molten aluminum dropping into the water, creating the possibility of an explosion
We said more difficult because, In reality, there is no correct answer for this, this is really a preference issue which depends on the company. Axsis Technologies has built and fabricated both down draft and water tables, and would be glad to build you preference.
