This printed kit adds a second-hose intake to the Blyss A018I-12CH. The Daewoo COL1579GE, identified in its manual as A018B-12CH, has the same published cabinet dimensions and is a strong may-fit candidate after a rear-photo clip check. We hold the files, print to order and post it tracked across the UK.

A single hose blows your cooled indoor air outside. That air has to be replaced, so warm outdoor air is pulled in through gaps around doors and windows. You are cooling air just to throw it away.
Because warm air keeps leaking back in, the unit runs longer to hold the same temperature. On the hottest days, when you need it most, a single-hose unit can struggle to keep up.
A second hose feeds the condenser with outdoor air instead of room air, so the room stays sealed and cools faster. It is the same principle used by higher-end portable units that ship dual-hose from the factory.
The complete kit was designed for the Blyss A018I-12CH. Blyss publishes the A018I-09C, A018I-09CH, A018I-12C and A018I-12CH in one family manual with the same 440 × 715 × 335 mm external dimensions and common casing drawings. Daewoo identifies the COL1579GE as an A018B-12CH and publishes exactly the same cabinet dimensions. These are strong shared-case candidates, but only the Blyss A018I-12CH is the exact design model.
The model the hose collar and rear intake backplate were made for.
Exact design modelSame published A018I casing family and dimensions. The cooling-only and heating versions differ internally.
May fit · rear-photo check requiredThe cooling-only 12,000 BTU sibling of the A018I-12CH, with the same published case dimensions.
May fit · rear-photo check requiredThe Daewoo manual identifies the underlying model as A018B-12CH. Its 440 × 715 × 335 mm cabinet and published rear fittings match the Blyss format; the intake-cover clips still need checking.
May fit · rear-photo check requiredBefore ordering for a model marked “may fit”: send the complete rating-label model and a straight-on photo of the lower rear intake. We will compare the grille outline and fixing points with the print before taking payment.
Everything below is included and printed to order. The renders come straight from the print files we hold.
Connects your second hose to the new intake.
Approx. 176 × 175 mm
Adapts the unit so the condenser can draw air from a second hose instead of the room. Shown with the threaded hose ring.
Approx. 210 × 213 × 163 mmThe designer’s own unit with the kit fitted. You supply one standard portable-AC exhaust hose. Not sure which? Message us before ordering and we will point you to the right one.
The complete set: both parts needed for the conversion are included. Nothing else to print or buy from us.

Tougher than PLA and handles the warm exhaust side well. Our default choice for this part and only a little more than PLA.
The most heat and UV resistant option. Pick this if the unit sits in a conservatory or strong direct sunlight.
Polycarbonate is the strongest, most heat tolerant material we print. More than this part strictly needs, but it will not blink at the exhaust side.
Cheapest, but it can soften in sustained heat and sun, so we do not recommend it for this part. Fine for a shaded room used occasionally.

A single-hose portable air conditioner pulls air from inside the room to cool its condenser, then blows that air outside. That creates negative pressure indoors, so warm unconditioned air gets sucked back in through gaps around doors and windows. A dual-hose setup gives the condenser its own outdoor air supply, so it does not depressurise the room. The result is faster, more efficient cooling, especially on hot days.
Nothing is missing. This is the complete printed set for the conversion: the rear intake backplate and the hose adapter, both included. The only thing you supply is a second exhaust hose, which is a standard portable-AC part. If you are unsure which hose fits, message us before ordering and we will point you to the right one.
We recommend PETG or ASA. These parts sit at the hot exhaust side of the unit and often near a sunny window, and standard PLA can soften in sustained heat and direct sunlight. PETG is our default and only a little more than PLA. ASA is the most heat and UV resistant option if the unit sits in strong sun. We print PLA on request but do not advise it for this part.
You do not need to upload anything, we already hold the print-ready files. Open the kit page, pick your material and colour, and check out. Postage is £5.55 Royal Mail Tracked 48, free on orders over £40. We print it to order and post it from Basingstoke, usually within a few working days.
The kit is designed for the Blyss A018I-12CH. Blyss groups the A018I-09C, A018I-09CH, A018I-12C and A018I-12CH in one family manual with the same published dimensions and casing drawings. The Daewoo COL1579GE / A018B-12CH also has the same published cabinet dimensions and matching rear arrangement. These related models are not guaranteed: send the rating-label code and a straight-on rear photo so we can compare the lower intake and fixing points before you order.
It is a strong candidate. Daewoo’s manual identifies the COL1579GE as the underlying A018B-12CH, with exactly the same 440 × 715 × 335 mm cabinet dimensions as the Blyss A018I-12CH. The rear filter, exhaust connection, drains and hose fittings also appear to match. The remaining uncertainty is the intake-cover clips, so please send a straight-on rear photo before ordering.
Complete printed kit from £34.50. PETG or ASA for heat resistance. Printed to order in Basingstoke and posted tracked across the UK: £5.55 postage, free over £40.
