Below is a simple 11-point checklist for those looking to invest in a mobile fume & dust extraction system. This may prove helpful as you review your options, and consider your particular needs.
This particular list is more pertinent for this performing heavy-duty welding. If your application calls for light or intermittent use, this check list might be overkill. If that is your situation, and you’d like to know what is available to you, please feel free to reach out. We’re here to help.
11-Point Mobile Fume & Dust Extraction Checklist
- Fan silencer included as standard
- Lockable wheels
- How is the Fan actuated? Is it via a physical switch, or by a welding sensor clamp?
- Fan start and light switch on the hood
- LCD display: for notification of the status of the fan, if the unit needs to be serviced, and if it is time to change the filter
- Customization via the push of a few buttons: select fan delay off time for automatic start, set automatic cleaning (on or off), & timer cleaning intervals
- Automatic cleaning of the main filter cartridge
- Mechanical and compressed air process to clean the main filter.Why is this important? During use dust bridges are created between the pleats. These dust bridges contribute to filter load, and cannot be cleaned exclusively with compressed air. You want a mechanical method to break these dust bridges. Typically, this is mechanical cleaning method is performed as the filter rotates during cleaning. While this is happening, compressed air is blown from the inside to expel the dust bridge out of the pleat. This type of process results in a cleaner filter, greater filter longevity, and overall cost savings as you don’t have to replace filters as often.
- Automatic damper – to prevent dust from leaking out during compressed air cleaning
- Easy removal of the dust bin
- HEPA filter – can this be added as an option?
