Manual

J&D Typhoon Exhaust Fan

How do I size my fan and shutters system?

Fan and Shutter sizing diagram

1. The first thing that you need to determine is the amount of air required. This is stated in CFM (Cubic Feet of Air per Minute).

2. Use the following formula to determine the CFM required for your greenhouse:
CFM = Length x Width x Height
Example: Greenhouse 12' wide x 24' long x 12' high requires 3456 CFM (12 x 24 x 12 = 3456).

3. Reference the above table. Select the appropriate combination of fan(s) to achieve the necessary CFM rating. Be sure to match the total CFM output for your exhaust fan(s) to the CFM ratings for your Inlet Shutters.

not to difficult to install. I removed the fan and motor to lighten it up during installation. Low speed is noisier than high and seems to vibrate more. It definitely moves the cooler air into my 48' greenhouse. Works as advertised.

quiet & effective

Completely assembled, quick installation, quiet and effective for 32K cu ft metal warehouse. Freight is not inexpensive.

Excellent fans!

This is an excellent fan with more than enough power to get the job done. The unit comes set up for hard-wire however, we wired it for plug-in (pig-tail not included) set up for easier maintainence. I just like the idea of being able to unplug it if need be. Very easy installation and the unit isn't overly loud. I have two of them installed at the back of a 24x60 greenhouse. Definitely recommend this product!
