Frequently Asked Questions
What is the difference between the 100SQN-B and the 100SQN-D?
The Loren Cook 100SQN-B is the belt drive build of SQN size 100, and the 100SQN-D is the direct drive build of the same size. The 100SQN-D stands 14 inches tall with its motor enclosed in the housing, so it suits tighter ceiling space than the belt drive unit.
Does the 100SQN-B come with a high pressure wheel?
The Loren Cook 100SQN-B comes with the standard SQN wheel, which Cook rates up to 4 inches of static pressure across the SQN line. The high pressure SQNHP wheel starts at belt drive size 135 and runs up to 5 inches of static pressure.
