Q1: Is the central core removable? What are the benefits?
A1: Yes, the central core is designed to be easily removable. This feature greatly facilitates on-site commissioning after installation, as well as future access to the ductwork for cleaning and maintenance without needing to remove the entire diffuser.
Q2: Can this diffuser be used for return air?
A2: Yes, certainly. Square ceiling diffusers can be used for both supply and return/exhaust air applications. When used for return air, they function similarly by connecting to the ductwork via the neck to effectively collect and exhaust room air.
Q3: How do the neck sizes correspond to the face sizes?
A3: We offer standard matching sizes. For example, a 150x150mm neck corresponds to a 300x300mm face; a 225x225mm neck corresponds to a 375x375mm face. This design ensures the diffuser fits perfectly with standard ceiling grid modules. Please refer to our product specification sheet for the complete size chart.
Q4: What should be noted during installation?
A4: There are three main points: First, ensure the ceiling cutout is accurately sized. Second, the connection between the diffuser neck and the ductwork must be well-sealed to prevent air leaks. Third, ensure the diffuser is installed level to avoid tilting which could negatively impact air distribution.
Q5: How do I clean and maintain the diffuser?
A5: Routine cleaning is simple: just use a soft cloth or vacuum cleaner to remove surface dust periodically. For a deeper clean, you can remove the central core, wash it with a mild detergent, let it dry completely, and then reinstall it. We recommend routine cleaning every 3-6 months.
