352 X80 Air Purifier Fresh Air Conversion Kit

  • Transform your unused 352 X80 air purifier into a fresh air system
  • The frame is versatile, offering three inlet positions—left, right, and rear—with various diameters (Φ60, Φ80, Φ100) available. Non-inlet positions are sealed with cover plates

 

Important Considerations:

  • The original air purifier utilizes four-sided air intake. Due to spatial constraints, the intake area is reduced, increasing air resistance. Airflow will decrease to varying degrees at the same fan speed. Ventilation efficiency cannot match a dedicated fresh air system; avoid unrealistic expectations regarding ventilation speed. Low-speed operation is primarily for maintaining air quality
  • This modification is suitable for ventilation in small rooms of approximately 15m2, delivering acceptable results
  • Your ductwork inner diameter should exceed 59mm, 79mm, or 99mm for successful installation

Printing Instructions:

  • PETG filament is recommended. Depending on your chosen inlet, approximately 500-700g of filament will be required
  • To prevent filament waste, we strongly recommend printing a tolerance test sample before proceeding. Ensure the test sample fits smoothly into the wheel socket with sufficient damping to prevent slippage

     

Installation Steps:

1. Remove the four corner wheels by simply pulling them out
2. Connect the four ABCD frames and insert them together into the wheel sockets
3. Reinstall the four corner wheels by inserting them directly
4. Install your chosen inlet
5. Install your chosen cover plate
6. Connect one end of the ventilation duct to the inlet and secure it with tape
7. Connect the other end of the ventilation duct to the outside
8. All done! Here's the result in my 15m2 room!
