KNOKOO FES035 Welding Fume Purifier Pre-Filter Cotton (10 sheets) | First layer of protection, intercepting large dust particles and reducing maintenance costs

1. Dedicated Protection, Lightening the Burden on the Main Filter

Features: As the first stage of filtration, it is specifically designed to capture large particles of PM60 and above, such as visible welding slag and dust.

Benefits: Effectively blocks approximately 80% or more of large particulate pollutants, significantly reducing the burden on the main filter element and contributing to its 2-3 times longer lifespan.

2. Economical and Convenient, Worry-Free Replacement

Features: 10-piece economic pack, low-cost design, recommended replacement cycle is 10-60 days (depending on usage environment).

Benefits: Users can stock up on sufficient supplies at once, resulting in extremely low cost per piece. No cleaning is required when dirty; simply discard and replace, making maintenance simple, quick, and cost-effective.

3. Precise Fit, Ensuring a Seat

Features: Specifically designed for the FES035 model, with precise dimensions (16.6*16.6*0.8CM).

Benefits: Ensures a perfect fit, preventing unfiltered air leakage through gaps (bypass), guaranteeing all airflow is effectively filtered.

4. Ready to Use Immediately, Completed in Three Steps

Features: No tools required; installation involves only three steps: "Shut down the machine - Remove the old cotton - Insert the new cotton."

Benefits: Any operator can complete maintenance within one minute, minimizing equipment downtime.

Product use:

The pre-filter element is a key component of the FES035 Fume Extractor and is designed to provide initial air filtration by capturing dust, debris and large particles (up to PM60). This guide describes its use, maintenance and suitability for use in various industries.

1. Installation:

• Turn off the FES035 Smoke Absorber before installing or replacing the pre-filter.
• Insert the Pre-Filter:Remove the old pre-filter and dispose of it properly.
• Slide the new pre-filter into the designated compartment, ensuring it fits snugly.
• Close the filter compartment securely and turn the device back on.

2. Maintenance​:

• Regularly inspect the pre-filter for visible dust or debris buildup.
• For light maintenance, gently clean the filter using a vacuum cleaner or a soft cloth. Avoid excessive cleaning, as it may damage the filter material.

3. Optimal Performance Tips:

• Regular replacement of the pre-filter helps protect the main filter, extending its lifespan and improving overall air purification performance.
• Always use authentic pre-filter cartridges specifically designed for the FES035 Smoke Absorber to ensure compatibility and efficiency.

4. Applicability:

The pre-filter cartridge is ideal for use in a variety of industries and environments:

• 3D Printing.
• Electronics Repair Industry.
• Laser Engraving / Marking Industry.
• Other Environments: Suitable for use in any setting where smoke, dust, or odors are present, ensuring a safer and healthier workspace.
