The Isomax 3 Speed from Can-Fan is the perfect product for quiet and large indoor cannabis gardeners. With its patented 3D rotor-stator system, it guarantees impressive air flows. What is unique about this fan is that it is actually integrated into a silencer system. The Isomax's steel housing is extremely well insulated with a special type of foam. This makes the fan very quiet, thanks to the combination of high-quality insulation and the low airflow turbulence.
