The Black Orchid Centri-Flo Extractor fan is a high quality, inline centrifugal fan that is comparable to the RVK inline fan. They have great air flow ratings and offer very high Pa resistance, meaning they are very effective with filters and long ducting runs. There are 3 versions available; standard plug and lead, two speed switchable and a temperature and speed control model.
Standard model – These work much like many other inline fans, in that you plug them in and off they go. They are single speed fans and will run at their peak speed when you turn it on.
Twin Speed model – As the name suggests, these fans have 2 operating speeds that the user controls with a 3 way switch (off, 1 & 2). This option gives the user a bit more flexibility in the grow room and is great if you want to keep all the same ducting sizes. By running a fan at faster speed through the filter and an identical fan on the slower speed, you can get decent air scrubbing system.
Temperature and speed control model – This version comes with a 4m temperature probe. This records the heat in the room and the fan speed will change accordingly. Simply set the temperature you require, adjust minimum speed and the fan will do the rest. This is a great option if you’re not around much.
Black Orchid Centri-Flo Extractor Fans come complete with power lead and UK plug. There is also a mounting bracket for ease of installation. To prevent overload, the fans also feature a thermal cut out system which will help prolong life. Across the variations, each fan size has the same maximum airflow speed as the other variants. These speeds are as follows –
100mm – 250m3/hr
125mm – 365m3/hr
