Supply Air Diffuser List

The SQ-A/SQ-G 4-way ceiling diffuser provides balanced four-direction air distribution with concentric stepped louvers. It features an extruded aluminum (SQ-A) or galvanized steel (SQ-G) construction with an oven-baked white powder-coated finish as standard. Built to fit standard ceiling grid openings such as 595 x 595 mm and 603 x 603 mm, it integrates with optional plenum boxes and dampers such as opposed blade, butterfly, or radial fan blade dampers to accommodate diverse HVAC airflow and balancing requirements.

The MB-A ball spout jet diffuser provides focused, high-velocity, long-distance air projection while maintaining low operating sound levels. Constructed entirely from aluminum with a white powder-coated finish, it incorporates a fully steerable spherical nozzle that swivels 360° to direct airflow wherever needed. Commonly wall-mounted in large, expansive venues like airports, ballrooms, concert halls, and theaters, it delivers targeted spot cooling or heating.

The SQD-A double deflection diffuser features a specialized center core profile designed to achieve extended throw distances in a perpendicular direction. This design delivers a higher room air induction and mixing ratio for uniform conditioning throughout occupied spaces. Constructed entirely from 1.2 mm extruded aluminum with a clean white powder-coated finish, it is sized for standard 595 x 595 mm or 603 x 603 mm ceiling modules and can be paired with optional volume control dampers and plenum boxes.

The MD-A drum jet diffuser is built for spaces demanding long throw distances and large air volumes, such as warehouses, shopping malls, and coliseums. Constructed from aluminum with a white powder-coated finish, it allows flexible air pattern adjustment via a rotating central drum for vertical deflection and individual pivoted louvers for lateral spread. Integrated perimeter gasket seals minimize air leakage and secure the drum firmly at the chosen angle, with an optional gear-type opposed blade damper for air volume control.

The MJ-A jet diffuser is built for long-throw and high-airflow applications, making it well-suited for high-ceiling commercial and industrial spaces. Built with an aluminum outer frame housing concentric rings with an oven-baked white powder-coated finish, it supports both ceiling and wall installations. The concentric nozzle core allows manual directional airflow adjustment up to 45° in all directions (up, down, left, and right) to tailor throw paths to the space layout.

The JS-A jet slot diffuser is designed specifically for high-ceiling interiors and perimeter glass facades. It projects high-velocity air streams downward along tall perimeter windows to prevent stagnant zones and counter downdrafts before reaching occupied floor levels. Fabricated from extruded aluminum with a durable white powder-coated finish, it is available in 1- or 2-slot formats in 1200 mm standard lengths and multiple slot widths to match required supply volumes.

The LD-A laminar flow diffuser is engineered for cleanrooms, hospital operating rooms, and critical healthcare spaces that require strict contamination control. It delivers low-velocity, unidirectional downward laminar airflow that shields the sterile field or patient area by isolating it from ambient airborne particulates. The assembly consists of a 1.2 mm aluminum casing, a 0.7 mm perforated aluminum face sheet, and a 1.2 mm extruded aluminum frame with an oven-baked white powder-coated finish designed to house terminal HEPA filter elements.

The LS-A linear slot diffuser is an architectural extruded aluminum supply unit offering an approximate 38% free area when blades are fully open. It features a white powder-coated frame complemented by black anodized adjustable pattern controller vanes, enabling precise directional airflow adjustment. Available in configurations from 1 to 4 slots in standard lengths of 600 mm (2') and 1200 mm (4')—along with 90° corner options—it is designed for seamless ceiling integration with matching insulated plenum boxes.

The PF-A perforated face ceiling diffuser is engineered to provide uniform, draft-free air distribution across large occupied spaces. It combines a 1.0 mm extruded aluminum outer frame with a durable 0.8 mm galvanized steel perforated face panel finished in baked white powder coat. Sized for standard ceiling layouts including 595 x 595 mm, 603 x 603 mm, and 1200 x 600 mm, it also offers an optional removable face mechanism for quick duct access, filter maintenance, and damper adjustment

The SQP-A plate type ceiling diffuser features a smooth, flat architectural face panel paired with a beveled outer frame made of 1.0 mm aluminum with an oven-baked white powder coat. It delivers subtle, uniform horizontal air throw while maintaining an unobtrusive ceiling aesthetic. The unit includes a removable center core that allows easy access behind the face panel to adjust integrated volume control dampers or connect to plenum boxes.

The MR-A round diffuser features concentric circular stepped cones crafted from 1.2 mm roll-formed aluminum sheet finished in white powder coating. It provides a full 360-degree horizontal air throw pattern ideal for open ceiling or exposed ductwork environments. Ranging in neck sizes from 150 mm up to 400 mm, the unit incorporates a removable center core for easy mounting, duct inspection, and balancing with optional radial fan blade or butterfly dampers.

The SQ-SW swirl ceiling diffuser utilizes 24 radial blades to generate a high-induction swirl airflow pattern that rapidly mixes supply and room air. This strong swirl induction creates a notable Coanda effect, preventing direct cold drafts on room occupants. Fabricated from galvanized steel or aluminum in standard T-bar ceiling module sizes 595 x 595 mm and 603 x 603 mm, it offers an optional tool-free openable face and allows volume control damper adjustment directly through the ceiling panel.
