Not every project fits a standard vent — and honestly, it shouldn’t.

We work with contractors and brands who need real engineering customization, not catalog limits.

Here’s what we can tailor for OEM & project orders:
• Custom lengths and 1–4 slot configurations
• Narrow edge, frameless, and pre-embedded frame options
• Multiple finishes, including wood-grain styles
• Structure optimized for condensation control
• Compatible with different duct and ceiling systems

Built on 15+ years of manufacturing experience, ISO 9001 processes, and exports to 10+ countries.

If you’re sourcing a reliable OEM HVAC partner, message us — happy to review your drawings or specs.

Most people never notice good airflow — but they always notice bad vents, stains, noise, or uneven cooling.

For building owners and contractors, HVAC outlets aren’t just fittings, they’re long-term performance parts.

Our compact central AC linear outlet is built for durability and clean operation:
• Anti-condensation structure with ABS + aluminum alloy
• Adjustable vanes for stable airflow control
• Smooth finish that resists deformation over time
• Recessed install helps reduce dust build-up
• Custom sizes available to fit your ceiling plan, no forced changes

Small component, big impact on comfort and maintenance cost.

Message us if you’re planning a project and need custom outlet options.

Good airflow is invisible — but poor quality never is.

For developers and property owners, ventilation components must deliver long-term stability, not just initial performance.

This compact linear AC air outlet is designed for durability, low maintenance, and visual consistency over time.

Value-driven features:
- Anti-condensation material design (ABS + aluminum alloy)
- Stable airflow output with adjustable vanes
- Clean surface finish resistant to yellowing and deformation
- Concealed installation reduces dust accumulation
- Custom sizing avoids forced structural modifications

A small component — but one that affects comfort, maintenance, and aesthetics for years.

Air distribution shouldn’t interrupt design — it should disappear into it.

In many modern projects, what architects and designers want is simple: clean lines, hidden systems, visual continuity. Traditional diffusers often break that flow. Slim linear air outlets are built to do the opposite — deliver airflow while staying visually quiet.

Our compact central AC linear outlets are developed for design-driven spaces where aesthetics matter as much as performance.

Design-focused features:
• Ultra-slim linear profile for modern ceilings and wall lines
• Optional wood-grain finishes — natural / walnut / dark walnut
• Minimal frame or frameless recessed installation options
• 1–4 slot configurations to match airflow needs without visual clutter
• Surface consistency for high-end residential and boutique commercial interiors

From apartments to showrooms, airflow becomes part of the design language — not a distraction from it.

When installation efficiency matters as much as airflow performance.

In many commercial HVAC projects, delays don’t come from major equipment — they come from details.

Air outlets that don’t align with ceilings, frames that protrude, or airflow that’s hard to balance.

This is why more contractors are choosing customized linear air diffusers for compact central AC systems.

Key engineering-oriented features:
- Linear slot design with 1–4 adjustable vanes (slots) for balanced air distribution
- 360° airflow direction adjustment, suitable for narrow ceiling spaces
- Pre-embedded installation options (gypsum board / plaster finish / frameless recessed)
- Composite ABS + aluminum alloy structure for anti-condensation performance
- Narrow frame options (≈1.5 cm visible edge) to reduce ceiling opening tolerance pressure
- Modular length customization for site-specific duct layouts

✔ Smooth airflow
✔ Simple installation
✔ Reduced rework on-site
For HVAC contractors, this means less coordination friction and cleaner project delivery.

Malaysia – Air distribution in commercial buildings

In Malaysian commercial buildings, cooling demand is high and operating hours are long.

But increasing air volume alone does not guarantee comfort.
If supply air enters only at isolated points, temperature differences appear quickly across large spaces.

Linear slot diffusers distribute air along a continuous line, helping:
-reduce thermal gradients
-improve overall air mixing
-avoid overcooling near outlets
-maintain comfort with stable airflow

JULAN linear diffusers offer adjustable blades and multiple slot options, allowing designers to tune airflow pattern without changing duct layout.

Efficiency is not only about equipment — it is about delivery.

Taiwan – Customization for architectural ceilings

Architectural ceilings are rarely standardized.

Designers work with:
custom lighting modules
irregular ceiling grids
and varied room widths
That makes fixed-size air outlets difficult to coordinate.

JULAN linear diffusers are produced with:
-customizable lengths
-1–4 slot configurations
-multiple installation styles
-optional surface finishes, including wood-look frames

This allows air outlets to follow architectural intent instead of forcing design compromises.

Air devices should adapt to space — not the other way around.

Taiwan – Condensation is an airflow problem

In Taiwan’s climate, condensation is not an occasional issue — it is a design constraint.

Cold air delivered in narrow jets often creates localized cold spots on ceilings, increasing surface condensation risk.
Linear slot diffusers help mitigate this by:
-spreading cold air across a wider ceiling line
-avoiding concentrated cold surfaces
-supporting smoother mixing with room air

JULAN linear diffusers further combine:
-anti-condensation composite materials
-adjustable blade angles
-customizable slot numbers based on load

Condensation control starts with airflow pattern, not only insulation.

Macau – Comfort in Large Public Interiors

In large spaces like gaming halls, hotel lobbies, and long corridors, comfort depends on one thing:

how evenly the air is delivered.

With point diffusers, people often feel:
cold air directly overhead,
while other areas stay warm and stuffy.

Linear slot diffusers create a different result.

Instead of isolated air spots, they form a continuous airflow line along the ceiling.

With JULAN linear diffuser design:
• air spreads across the ceiling plane
• airflow direction avoids occupied zones
• draft sensation is reduced
• temperature stays more balanced

In public buildings, comfort is not about stronger cooling.

It is about removing hot and cold extremes where people move all day.

Macau – Built for 24/7 Operation

In Macau’s hotels and gaming facilities, HVAC systems run almost nonstop.
So performance is not just about peak load — it’s about staying stable over time.

What really matters:
material stability
condensation control
consistent airflow day after day

JULAN linear diffusers use a composite ABS + aluminum structure to help:
resist deformation under long-term cooling
reduce surface condensation risk
keep blade alignment stable
maintain smooth airflow during continuous operation

With multiple slot options, airflow can be distributed along long ceiling runs instead of concentrated at a few outlets.

For buildings that never sleep, durability becomes part of comfort.

✔ Full aluminum body for corrosion resistance
✔ Ideal for offices, hotels, and retail spaces

A practical solution when design and air distribution need to work together.Message us to discuss your HVAC diffuser requirements.

Hong Kong – Ceiling integration with architecture

In Grade A office and mixed-use developments, HVAC components are no longer hidden infrastructure.

They are part of the ceiling system.

Architects increasingly align:
-lighting lines
-ceiling joints
-and air outlets into one continuous visual language.

JULAN linear diffusers are designed for this coordination:
- narrow-frame or frameless appearance
- custom lengths aligned with lighting modules
- slot numbers matched to air volume
- flush installation with gypsum ceilings

Instead of breaking the ceiling rhythm with square outlets, air distribution becomes part of the architectural grid.

This is not only about aesthetics — it simplifies coordination between architectural and MEP drawings.
