Dr.Air KH-380 Electronic Welding Fume Extractor

Product Description: Dr.Air KH-380 Electronic Soldering Fume Extractor

1. Product Overview

Dr.Air presents the KH-380, a specialized fume extractor designed for electronic circuit board soldering. Operating at a power of 200W with an airflow capacity of 380-400 m³/h, this device fully meets the demands for treating smoke and dust in electronics manufacturing.

With a minimalist design, modern technology, and premium materials, the Dr.Air KH-380 is the top choice for businesses prioritizing a clean working environment.

2. Key Advantages

• Sleek Design: Simple yet professional aesthetic.

• Dual Extraction Arms: Two smoke ducts allow for simultaneous operation, doubling efficiency.

• Durable Build: The body is made of powder-coated metal, ensuring high durability.

• Flexible Ducts: The extraction arms are made of heat-resistant plastic. They can be extended, retracted, and rotated 360 degrees to fit any workspace requirement.

• Portability: Integrated handles on both sides make moving the unit easy.

• High Filtration Efficiency: The multi-stage filtration system removes up to 99.97% of dust and smoke.

• User-Friendly: Simple control panel for easy operation.

3. Multi-Stage Filtration System

The Dr.Air KH-380 utilizes a comprehensive three-layer filtration method:

1. Primary Filter

2. Intermediate Filter 

3. High-Efficiency Filter 

Capabilities:

• Particle Removal: Effectively filters and absorbs oil mist and soot particles larger than 0.3μm with a purification rate of 99.7%.

• Toxic Gas Absorption: The high-efficiency filter incorporates Composite Activated Carbon, which absorbs common hazardous gases such as Benzene, Ketones, Alcohols, Alkanes, and mixed organic exhaust.

• Safe Recirculation: The purified air is safe to be discharged directly back into the room without harming human health, achieving both air purification and energy conservation goals.

4. Why Use a Fume Extractor? (Health & Safety)

The Origin of Toxic Fumes: Hazardous substances in soldering fumes originate from base materials, inert gases, coatings, and ambient air. They are formed through physical and chemical processes like evaporation, condensation, oxidation, and combustion.

Health Risks: Regardless of the source, gases and metal dust generated during soldering pose serious risks to human health, particularly the respiratory system. Research links welding/soldering fumes to lung cancer and nervous system damage due to the presence of heavy metals like Nickel, Chromium, and Manganese.

• Nickel & Hexavalent Chromium: Classified as potential occupational carcinogens.

• Manganese: Chronic exposure is linked to Parkinson’s-like symptoms.

Specific Effects of Toxic Components: Hazardous substances become toxic when they reach certain concentrations. Below are the specific risks:

• Manganese Oxide: Respiratory irritation, Pneumonia, Nervous system damage, Parkinson’s disease.

• Zinc Oxide: Metal Fume Fever (nanoparticles in lungs leading to cell necrosis).

• Copper Oxide: Nausea, diarrhea, eye pain, Metal Fume Fever (chills), Liver and Kidney damage.

• Nitrogen Oxides: Respiratory irritation, shortness of breath, potentially fatal Pulmonary Edema.

• Carbon Monoxide (CO): Blocks oxygen uptake in blood. Symptoms include dizziness, fatigue, fainting, cardiac arrest, and respiratory paralysis.

• Carbon Dioxide (CO2): Increased breathing rate, dizziness, headache, unconsciousness.

• Phosgene: Severe respiratory irritation, Pulmonary Edema.

• Other Toxins: Soluble Barium compounds, Calcium Oxide, Fluorides, and Vanadium Pentoxide.
