Product catalog summary
DF-LIT-E Linear Diffuser Overview
The DF-LIT-E is an 'invisible' linear slot diffuser designed for installation in modular or continuous drop ceilings. It is characterized by the absence of visible profiles, making it ideal for aesthetic installations requiring a continuous line. The diffuser can be manufactured with different slot widths to accommodate varying air flow rates per linear meter for both supply and extract purposes.
Applications
These diffusers are suitable for ceiling installations, particularly effective for constant flow rates but also perform well with variable flow rates. Recommended installation height is between 2.5 to 4 meters, with air flow rates ranging from 150 m3/h to 500 m3/h per meter, and throws up to 6 meters for a temperature differential of ±10 ºC.
Designs and Finishes
The DF-LIT-E is finished in anodized aluminum painted to RAL 9005, ensuring only one slot is visible in the ceiling. It includes a galvanized plenum box, with or without insulation, and an optional integrated volume control damper accessible from the diffuser's front face. The diffuser is available in various designs for horizontal and vertical air diffusion.
Technical Specifications
The diffuser is available in lengths of 1000 mm with a 40 mm slot, designed for horizontal air supply with the Coanda effect. It includes an uninsulated supply plenum made of galvanized steel and a volume control damper at the inlet. The standard finish is glossy paint (RAL9010), with other RAL colors available upon request. Diffusers longer than 2000 mm are supplied in sections for assembly.
Performance Data
The document provides a detailed selection table with performance data, including air flow (Q), effective area (Ak), effective supply velocity (Vk), throw (X), total pressure drop (Pt), and sound power level (LW-dB(A)) for various configurations.
