Opticlimate Vibration Springs - Pack of 4Overview The Opticlimate (OC) vibration springs are part of the Opticlimate spares range and prevent the unit from making noise or from shaking. The springs also position the closed loop climate system at a slight angle so the condensation drain works optimally. The springs reduce vibration of the closed loop climate system by up to 98%. The units maximise the air conditioning system's efficiency to ensure optimum grow room environment conditions.
