The new white 2018 Rhino Twin Speed Fan from the world leaders in grow room carbon filter technology.
Rhino Twin speed fans provide the grower with the flexibility to move between a higher or lower velocity as their requirements change throughout their growing cycle. A robust and maintenance free fan that produces a minimum amount of noise and allows the grower to ventilate their grow room in an efficient manner. The durable casing is manufactured from reinforced plastic and on particular models steel, to give the fan a very strong outer casing that prevents leaks.
All Rhino Fans come completely wired with a 2mtr cable and UK plug, ready to use from the box.
To calculate how big a fan you will require: Simply multiply the length x width x height of your grow room in mtrs which will give you the cubic capacity of your room ..and then multiply that value by either 30 or 60 which is the minimum and maximum air changes required per hour for optimum ventilation in your grow room.
For example: A grow room measuring 2mtrs x 2mtrs x 2mtrs = 8mtrs cubed x30 air changes an hour = 240mtr cubed per hour will need to be ventilated ..as a rule we recommend buying a slightly larger capacity fan than you need, to allow for summer increases in temperature and or using a carbon filter
