Manual Adjustable LWD-M
01. LWD-M: Flexible Control for Customized Air Distribution
Designed for applications requiring frequent on-site adjustment, the LWD-M series features optional 2-slot, 3-slot, and 4-slot configurations. Each linear slot is equipped with a rotatable wheel-type core, allowing users to manually redirect airflow direction with precision. The adjustable louver angle ranges from 11° to 169°, providing flexibility to meet diverse ventilation requirements across different zones.
It also delivers multiple core advantages: a large effective free area ensures smooth airflow; low airflow resistance minimizes energy consumption while maximizing outlet efficiency; high air volumes and extended throw enable uniform air distribution even in expansive spaces; and low sound levels prevent disturbances in offices, leisure areas, and other daily environments, comprehensively enhancing the overall ventilation experience.
02. LWD-T: Automatic Control for Efficiency and Convenience
Equipped with an integrated thermal actuator, this model eliminates the need for frequent manual intervention. It automatically adjusts the blade angle in response to supply air temperature fluctuations, intelligently adapting to seasonal ventilation demands between summer and winter. This provides a truly passive, efficient, and worry-free solution for climate control.
Summer Mode: Horizontal Ceiling Attachment：In summer mode, the blades automatically shift to a horizontal ceiling attachment configuration. This generates a high-velocity, long-throw airstream that rapidly mixes the indoor air. By promoting thorough air circulation, it ensures uniform temperature distribution throughout the space, eliminating localized hot spots and significantly enhancing overall thermal comfort.
Horizontal Air Supply in Summer
Winter Mode: Vertical Downward Discharge：In winter mode, the blades automatically shift to a vertical downward discharge. Leveraging low airflow resistance and high outlet velocity, this configuration counteracts the natural buoyancy of warm air (which tends to rise). It delivers high-efficiency, long-distance heating that ensures stable and superior warmth distribution throughout space.
Vertical Air Supply in Winter
03. Optional Plenum Chamber: Streamlined Installation
The LWD series Linear Wheel Diffuser are available with an optional plenum chamber. Featuring a circular duct connection collar, it allows for quick and efficient on-site duct hookup, significantly reducing installation time. Internally lined with elastomeric insulation, the plenum requires no additional external thermal wrapping. This design not only lowers construction costs but also effectively mitigates the risk of condensation (sweating), perfectly balancing practicality with installation ease.
With its superior airflow dynamics and universal adaptability, the LWD Series Linear Wheel Diffuser stand as the professional choice for diverse environments. From corporate offices and convention centers to hotel lobbies, libraries, museums, and sports arenas, the LWD series delivers.
It is particularly tailored for high-ceiling spaces and large-scale venues demanding stringent environmental comfort and extended throw capabilities. Empowering your space with lasting comfort.
