SMS Hybrid Controller 4a




Mk2 SMSCom Hybrid Pro Fan Speed Controllers are the simplest, quietest and most efficient way to regulate the output of in-line duct fans –just plug them into the controller, set the dials and let the on-board computer system do the rest. Hybrids completely remove buzzing and humming noises by combining heavyweight transformers with clever digital technology. This model is the most popular in the range – and it’s now been upgraded at no extra cost! It features a ‘maximum’ setting so that you can use over-sized fans without them ever kicking in at their full output level. The Pro’s light sensor can be used to increase extraction levels for 7 minutes an hour during darkness hours, lowering humidity levels and preventing issues with rot. These improvements really have turned a great product into something truly legendary!
