⚡ UPDATED* Custom Dual-Hose Adapter for Screwfix Blyss Portable Air Conditioners (A018I-12CH & A018I-09C) ⚡
*Hose connector no longer required
⚠️ PLEASE NOTE: This listing is for the 3D-printed ADAPTER ONLY. Air conditioner and hoses are not included.
Upgrade your portable air conditioner to a highly efficient dual-hose system.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Single Hose (Standard): Cools your room, but constantly forces air out of the exhaust. This creates a vacuum (negative pressure) that sucks hot air from outside or other rooms back in through doors, windows, and floorboards. Your AC is constantly fighting against itself.
Double Hose (With this Adapter): Keeps indoor and outdoor air completely separate. One hose pulls outside air in to cool the compressor, while the second hose blasts that hot air right back out. Your cold indoor air stays inside, cooling your room much faster and using less electricity.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Designed specifically for:
Screwfix Blyss A018I-12CH (12,000 BTU/h)
Screwfix Blyss A018I-09C (9,000 BTU/h)
Unconfirmed Compatibility: Based on research, the OEM for this Blyss unit appears to be the Trotec PAC 3501 S WiFi. While the adapter may fit this model, this is unconfirmed and I am not affiliated with Trotec.
I also had confirmation that this will fit Daewoo COL1579 12k Btu, BLACK+DECKER BPP08HWTB 12,000-BTU & Honeywell HT09CESAWK (Photos attached)
I have a list of compatible ACs. Please send me a message to check if you are unsure if it will fit your AC.
Please check your exact model number before ordering. Because this is a custom-designed item, returns cannot be accepted for compatibility/fit issues on other models.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Durable Material: 3D-printed in premium PETG, which handles ambient and exhaust heat exceptionally well. I have been running this exact setup on my own air conditioner since 2023 without any issues.
Strong, Single-Piece Design: Each adapter is printed as a single, solid piece (no weak glue seams or joints) for maximum durability.
Finish & Color: As with all 3D-printed parts, there may be minor, cosmetic surface imperfections that do not affect performance. I personally inspect every adapter before shipping to guarantee structural integrity. I ship these in whatever neutral color filament (usually white, or grey) I currently have in stock.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Lead Time: Each adapter takes approximately 14 hours to print. I print these on demand and work through the queue as quickly as possible. Please bear with me if there is a minor delay. If you are in a rush, please message me before purchasing to get a current estimate on lead times.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
To complete your dual-hose setup, you will only need to source the following separately:
Flexible Venting Duct: A standard 150mm (6-inch) flexible AC exhaust hose.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Insulate your exhaust duct: Standard plastic hoses radiate a lot of heat back into the room. Wrapping your exhaust hose in reflective insulation makes a massive difference.
Hose Placement: Ensure your intake and exhaust hoses are positioned at least 50cm apart at the window. This prevents the intake from sucking in the hot exhaust air you just expelled.

Disclaimer: This is an aftermarket, custom-designed modification. You are installing and using this adapter at your own risk. Please double-check your AC model compatibility before purchasing.
