The Stealth 4” in-line fan is well suited for micro-gardeners or those starting off with a 1-2 plant set up. With a CFM of 189, they can be used in a sealed grow tent to effectively stir up the inner atmosphere and remove expired CO2, leaving room for fresh outside air to access your plants. This 4” model features a muted mechanical design and resistant materials that make cleaning and maintenance a breeze.
Stealth in-line blower fans can be used to ventilate any grow system (soil-based, aeroponic or hydroponic), at any scale and for both open loop and closed loop. It is always recommended, during installation, to consider all circulation components when establishing your overall CFM metric for compatibility.
To keep your plants happy, grow room air should be replaced ideally once per minute. Compared to other models on the market at the same inlet size, each Stealth in-line fan is engineered with a hyper-efficient CFM rating. This feature was made to accommodate ventilation configurations with a high CFM carbon filter as well as potential lengthy ducting and sharp duct corners, all of which will impact airflow speed. Stealth in-line fans should be installed as elevated as possible and placed directly inside your grow space to optimize airflow and to sustain their CFM capacity.
