The RAM 450mm (18”) Heavy Duty Wall Fan – 3 Speed will give you high-volume air movement without taking up floor space. This sturdy wall-mounted fan oscillates to ensure even distribution of air over the whole grow room. Its robust 100W motor drives metal fan blades at a choice of 3 speeds to produce a quiet but impressive air flow. Fan speed and oscillation controlled by pull cords for convenience. Totally safe, with high grade wire-cage fingerguards which are less prone to accumulate dust and dirt than expanded-metal or plastic guards. Supplied complete with steel wall-mounting plate and fixings.
