Product Description

Core Product Features

  • Grill Structure: Available in fixed and detachable grille types. The grille bars are evenly spaced, providing a large ventilation cross-sectional area and low airflow resistance. Some models feature an integrated “grill + filter” design, combining return air and filtration functions.
  • Appearance Design: Clean, simple lines; available in square, rectangular, and strip shapes. The powder-coated surface color can match the ceiling/wall for visual integration.
  • Functional Expansion: Can be equipped with sound-absorbing cotton to reduce supply air noise; can also be combined with airflow regulating valves for precise control of return air volume.

Applicable Scenarios

  • Main Uses: Central air conditioning return air vents, fresh air vents, or public areas with high aesthetic requirements (e.g., corridors, elevator lobbies, stairwells, underground parking garages).
  • Special Scenarios: Places with noise control requirements (e.g., libraries, archives), large shopping malls, factories requiring high-volume return air.

Core Value

  • Uniform Airflow: The grille structure ensures more even distribution of return/fresh air, avoiding localized eddies and improving system efficiency.
  • Highly decorative: Its minimalist design makes it suitable as a decorative element for ceilings or walls, replacing traditional, obtrusive air vent designs.
  • Easy to clean: The removable grille design allows for easy removal and cleaning of the filter and internal dust, resulting in low maintenance costs.
