G.A.S DiffuseAir


The DiffuseAir, developed by Systemair, effectively manages the airflow in your grow room, providing complete climate control. This system excels in removing microclimates, areas of high humidity, and hot spots, while also preventing strong air currents that could lead to wind burn on plants and salt build-up in the soil.

Installed from the ceiling, DiffuseAir frees up valuable floor space, enhancing your growing area.

Key Features:

  • Aerodynamically efficient design
  • Utilizes proven technology
  • Ceiling-mounted to maximize growing area
  • Includes a 12-month warranty
  • Comes with necessary screws and brackets

Air Distribution: DiffuseAir draws air from the top of your grow space and disperses it over the plant canopy, efficiently managing air between the grow lights and plants. This is particularly effective in reducing temperature variations in both ventilated and sealed grow rooms. In a square room, a single centrally located DiffuseAir unit can replace multiple traditional air movement fans.

Inlet Distribution: DiffuseAir can also serve as a hub for introducing fresh air into your grow room. By connecting ductwork to the unit, you can channel fresh external air directly into the space, making it a key component in your climate control system. This setup optimizes the distribution of CO2-rich air, delivering it exactly where your plants need it most.

Multiple Systems: In larger grow spaces, traditional oscillating fans can create uneven air movement, which can stress plants by increasing transpiration and potentially causing wind burn or salt buildup in the soil. Strategically placing multiple DiffuseAir units above your plant canopy can help evenly distribute air, thus mitigating hot spots and reducing humidity pockets.
