CAN-FAN ISOMAX (aka Airforce 2 fan) 3-Speed and single speed sound insulated fans are designed and constructed to minimalize sound output at range which makes them the ideal grow room inline fan for where noise sensitivity is a priority.
The ISOMAX powerful Swiss engineered high-quality motor runs extremely quiet while moving a very large amount of air through either a 150mm, 200mm, 250mm and 315mm outlet. The outer casing functions as a silencer and has a thick layer of insulating foam-lining around its inside, providing outstanding sound protection. Remarkably lightweight, ISOMAX fans can be suspended/ installed in locations that may be unsuitable to consider other, heavier, cabinet/box type acoustic fans. Two built-in hanging fittings allow for easy, quick installation.
The 3-speed fan-controller offers the ability to reduce air-flow levels when it may be preferable, providing added flexibility and saving money on additional fan-controller units!
These fans are highly reliable, durable and overheating is prevented by a thermal switch, so peace of mind can be maintained at all times.
To calculate how big a fan you will require: Simply multiply the length x width x height of your grow room in metres 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.
*ISOMAX 3-Speed fans may be used in conjunction with the SMSCOM range of Hybrid fan controller or Rhino controllers (not RC-1 controller) with the fan set to its highest speed.
