Product use:

1. Replacement Guidelines

• Replacement Cycle: Recommended every 10-60 days, depending on the level of pollution in the operating environment.

• When to Replace: Replace the filter when:

  • Dust and oil accumulation exceeds 70% of the surface area.

  • The machine's suction power noticeably decreases.

  • The filter cannot be adequately cleaned or restored.

2. Replacement Process

• Turn off the fume extractor and unplug it from the power source.

• Open the filter compartment and carefully remove the used pre-filter cotton.

• Install the new pre-filter, ensuring it is securely positioned.

• Close the compartment and restart the machine.

3. Maintenance and Care

• Regular Cleaning: Periodically inspect the filter. Lightly tap or use compressed air to remove accumulated dust if applicable.

• Optimize Performance: Pair regular filter cleaning with consistent replacement of the pre-filter to enhance the performance of the entire filtration system.

• Use Original Filters: Opt for original pre-filter cotton to maintain compatibility and ensure maximum filtration efficiency. Non-original filters may compromise performance and reduce the machine's lifespan.

4. Precautions

• Store and use the pre-filter in a dry, cool environment away from direct sunlight, high humidity, or extreme temperatures exceeding 60°C.

• Avoid using or storing the filter in flammable, explosive, or wet environments, which could lead to equipment damage or safety hazards.

• Regular inspection and timely replacement are crucial to sustaining the fume extractor's performance and ensuring safety.
