RAM AIR PRO II

Description

The RAM Air Pro II is a high-performance oscillating room fan engineered for the demanding environment of indoor growing rooms. RAM is a brand built specifically for the horticulture market, and the Air Pro II reflects decades of feedback from professional growers about what matters most in grow room air circulation: consistent airflow, reliable oscillation, quiet operation, and the durability to run continuously for months without mechanical failure.

Why Proper Air Circulation Is Critical for Indoor Growing

Air movement in a grow room does far more than keep temperatures comfortable. It strengthens plant stems through mechanostimulation — the process by which physical movement triggers plants to thicken their structural tissues in response. Stronger stems support heavier bud loads and reduce the risk of branch collapse under the weight of late-flowering development. Air movement also disrupts the boundary layer of stagnant, humid air that forms around leaf surfaces, improving transpiration efficiency and CO2 uptake at the leaf level. Crucially, constant air movement removes the still, humid microenvironments in the canopy where fungal pathogens including Botrytis and powdery mildew establish most readily. A well-circulated grow room is a much less hospitable environment for disease. We have been advising UK growers on room ventilation and air movement since 2017, and proper oscillating fan placement is one of the most consistently impactful recommendations we make.

RAM Air Pro II Features and Specifications

The Air Pro II features a wide oscillation arc that sweeps airflow across the entire room rather than concentrating it in a single direction. Multiple speed settings allow you to dial in the intensity of air movement for different growth stages — lower speeds for delicate seedlings and cuttings, higher speeds during vegetative and flowering growth when stem strengthening and disease prevention are the priority. The fan is freestanding with an adjustable height column, allowing you to position the airflow head at precisely the canopy level where it is most needed. Its robust construction and efficient motor make it suitable for the continuous-duty operation that growing rooms demand.
