数でゴリ押し作戦もまさかの結果！激安＆簡単はんだ吸煙器の自作実験をご紹介します！

Summary

In this DIY video, the creator explores the feasibility of building a cost-effective soldering fume extractor. They discuss the health hazards of inhaling soldering fumes and the high cost of commercial extractors. The experiment involves using affordable PC fans and various filters, including HEPA and activated carbon, to create a homemade version. Despite initial attempts with axial flow fans, the video concludes that a centrifugal fan or cyclone type might be necessary for effective filtration, suggesting that while a budget approach is possible, it may not suffice for capturing harmful particles.

Takeaways

Q & A

What is the main purpose of a soldering smoke extractor?

A soldering smoke extractor is a device designed to capture and remove smoke generated during soldering processes, which can be harmful to health and cause discomfort due to coughing and irritation.

Why are commercially available soldering smoke extractors expensive?

Commercially available soldering smoke extractors are expensive due to their brand value, the cost of the filters used to remove harmful substances, and the overall manufacturing and marketing costs.

What is the DIY approach to creating a soldering smoke extractor as described in the script?

The DIY approach involves using affordable PC fans, which are cheaper and can be found easily, to create a fan system that can draw in smoke. The script also mentions using a 3D printer to create a fixture for the filter and experimenting with different types of filters.

What type of fan did the script suggest using for the DIY soldering smoke extractor?

The script suggested using a 12cm PC fan, which is cost-effective and has good silent performance, but noted that it has a significant drawback of being underpowered.

What is the issue with using multiple PC fans stacked vertically for the DIY extractor?

Stacking PC fans vertically can help increase the suction power, but since these fans are not designed for this purpose, they may not perform optimally, and the overall performance might not meet the expectations for a smoke extractor.

What is the role of filters in a soldering smoke extractor?

Filters in a soldering smoke extractor are crucial for removing harmful substances from the smoke. They are typically made of activated carbon, which can adsorb these harmful components.

Why are activated carbon filters expensive and require frequent replacement?

Activated carbon filters are expensive because of the material cost and the process involved in activating the carbon. They require frequent replacement because they can become saturated with harmful substances over time, reducing their effectiveness.

What alternative filter did the script suggest for the DIY extractor?

The script suggested using air purifier filters, which are more cost-effective and come with a combination of activated carbon and HEPA filters, offering a high-performance solution.

What is the significance of static pressure in the context of the DIY extractor's fan?

Static pressure is significant because it determines the fan's ability to overcome resistance, such as that from filters. Fans with low static pressure, like the PC fans used in the DIY project, struggle to pull air through filters effectively.

What was the conclusion of the experiment regarding the use of PC fans for a soldering smoke extractor?

The conclusion was that while it is possible to create a basic smoke extractor using PC fans, the results are not satisfactory for effectively capturing and filtering harmful substances due to the low static pressure of the fans.

What type of fan is recommended for a more effective DIY soldering smoke extractor?

The script suggests that a centrifugal fan or a siphon fan, which has higher static pressure, would be more suitable for an effective DIY soldering smoke extractor that can handle filters with higher resistance.
