Q: Can this vent be turned completely off? How is it installed? Thanks
Yes, this vent can be rotated fully closed by turning it 90 degrees clockwise. Here are the installation details: "The body of the air vent requires a 1.850 diameter or larger clearance hole. The vent is secured using 4 #10 screws located on a 2.375 diameter bolt circle. The ball and nozzle subassembly can be removed for access to the back if machine screws and nuts are used rather than sheet metal screws."
Q: What is the weight of this ACS eyeball swivel vent?
0.13 lbs.
Q: What is the recommended flange size for this swivel vent? I would like to know the flange diameter and SCAT tube diameter that work best with this vent. How is the flange attached to the vent? I am guessing that a hole pattern that matches the pattern on the vent is drilled into the flange and then mounted on the back side using the 4 #10 crews.
The manufacturer offers a round flange, part number 10350-8, but it does not have the mounting holes drilled. The installer must drill the holes. 10-32 flush head screws can be used to mount the unit. The vent on the panel, and the flange mounted on the back side, as mentioned in the question.
Q: Does this swivel to direct air flow?
