Dr.Air KHS-4800 High-End Welding Fume Extractor

1. Product Overview

The Dr.Air KHS-4800 is a specialized industrial fume extractor designed to treat dry, oil-free, and non-corrosive fumes generated during metalworking processes.

Engineered with a robust dual-stage filtration system, the unit first captures large particles before passing the air through a secondary stage for fine dust elimination. It is the premier choice for industrial facilities looking to effectively remove hazardous welding fumes and particulate matter.

2. Key Features

• High-Capacity Performance: Delivers a processing airflow of up to 4800 m³/h, ensuring rapid and effective air purification.

• Nano Filtration Technology: Effectively captures ultra-fine dust particles, safeguarding worker health.

• Durability: The casing is constructed from high-grade materials, designed to withstand high temperatures and mechanical impact.

• Portability: Despite its industrial power, the unit features a compact design with wheels for easy mobility between workstations.

• Safety Mechanisms: Equipped with built-in overload and overheat protection for safe, continuous operation.

3. Working Principle (How it Works)

The Dr.Air KHS-4800 operates on a streamlined 4-step process to ensure maximum efficiency:

1. Extraction: The high-power fan generates strong suction, drawing welding fumes and dust into the intake hood.

2. Transport: Fumes are transported through the heat-resistant suction arm into the main filtration chamber.

3. Filtration: The air passes through the multi-layer system. The Nano filter core traps microscopic particles and toxic smoke.

4. Discharge: Clean, purified air is recirculated back into the working environment.

4. Structural Components

The system is comprised of:

• High-power suction fan & durable motor.

• Heat-resistant suction arm & hood.

• Multi-stage filtration system (featuring Nano technology).

• Insulated filter chamber.

• Sturdy frame with 360° mobility wheels.

Important Safety & Operation Guidelines

To ensure safety and longevity of the KHS-4800, please strictly follow these instructions:

Pre-Operation Checks:

1. Connections: Ensure all hose connections and joints are tightly sealed to prevent suction loss.

2. Power Supply: Check that the power source and electrical components are connected correctly before starting.

3. Placement: Place the machine on a flat, solid surface to prevent vibration, tipping, or excessive noise.

4. Clearance: Maintain a clearance of 50cm – 100cm around the machine for proper airflow.

Operating Cautions: 5. Prohibited Materials: DO NOT use this machine to filter air containing oil, water/moisture, flammable gases, or corrosive fumes. Moisture and oil can clog the filter cartridge or cause damage. 6. Fire Hazard: strictly prohibit suction of burning items such as lit cigarettes, burning paper, or cotton into the machine. 7. Moving: When moving the unit, do not tilt it more than 45 degrees. 8. Electrical Safety: Ensure the voltage matches the machine’s specifications. Do not share the power outlet with other heavy appliances.

Maintenance: 9. Shut Down: Always turn off the power switch and unplug the device when not in use. 10. Unauthorized Repair: Do not disassemble the device without professional authorization. 11. Routine Care: Regularly check the seals and clean the dust from the unit to extend the machine’s lifespan.
