Electronically Commutated (EC) the Revolution EC Vector fans combine AC and DC voltages, bringing the best of both technologies. Easy speed controllability, efficiency, lower power consumption and higher m3/h can be achieved. State of the art energy saving brush-less EC fan technology Absolutely no hum or vibration even on lower speeds Small loss of airflow when under pressure compared to other fans High Power, example RV250L EC 1520m3/h with carbon filter Add another fan in series to double the pressure One piece housing so is air tight lightweight and compact Quieter than acoustically cased fans when combined with acoustic ducting Maintenance free and reliable quality – Made in Germany Learn More

6 Meter Length. Phonic Trap Acoustic Ducting works to reduce the noise produced by your extraction system. This ultra silent ducting can even block out the sound of some of the most powerful fans. The noise from vibration of air flow moving down ducts is often a huge problem for regular growers, so having decent, silent ducting in place is a must. Luckily, Phonic Trap is the best ducting that the industry has to offer. This means you'll get greater airflow, with barely any of the noise. Learn More

The Smscom Twin Fan Speed Temperature Controller is a quality piece of advanced kit that automatically adjusts the speed of your intake and outlet duct fans to maintain a user-set temperature in your grow room. The Smscom twin fan speed temperature controller also allows the user to select a minimum fan speed (to maintain a certain level of air exchange) and how much faster the outtake fan should run compared to the intake fan (to help keep a negative air-pressure inside the grow-space). After a short "learning" period, the Smscom twin fan speed temperature controller maintains steady fan speeds, increasing the speed when the temperature begins to rise and reducing it when it begins to fall. The Smscom twin fan speed temperature controller really is the bees-knees when comes to precisely controlling your garden environment! Learn More
