Air register that really closes
|
|
| nchampio@sprynet.com 2005-07-28, 1:21 am |
| Does anyone know of a company that makes an air register that you can
really close. Every one that I can find still has a steady air flow
through it even when it is in the "closed" position. Surely someone
makes one that really seals off when you close it. I've tried the
magnetic sheets to cover one and they don't stick very well to a
ceiling register. Thanks for any help.

Why would you *want* to close a register??
Do you also partition off the part of the fridge that you are not using??
Do you also close off the part of your oven that your not using??
Your duct system is designed for an exact amount of airflow to specific
locations.
When you close grills, you screw up the entire air distribution balance.

Why would anyone want to absolutely close a ceiling register. They're
supposed to be designed for distributing air and it's really not even their
function to use them for balancing (makes them noisy, etc) - a spiggot
damper's what should be used for balancing and if you must absolutely shut
off the airflow: shut the spiggot and then blank and tape the register.

| Because the register is in an area where I do audio recording and when
I am actually in session I want to totaly close the vent off. It
remains open the rest of the time.

No wonder you've got problems mon... your almost closed register will
probably be making a right royal racket (it'd be quieter fully open). I take
it that this is a register on a base building system and you've never had
any input from an acoustic designer when doing your fitout.
Seriously - your simplest solution is to install a quality motorised spigot
damper with felt seals as close to the main duct as practicable. Another
approach is to install active audio feedback into the space at the register
discharge which I've known to eliminate all A/C noise while still providing
effective air movement (I made a room so quiet once that the occupants could
hear the blood pumping through their heads and I had to tweak the feedback
down and introduce some white noise).
Other considerations should be the minimisation of hard surfaces and
possibly introducing sound absorbing in this area. Also watch out for those
light fittings that "buzz" (usually when dimmed but faulty ballasts can also
do it at full tilt).

Drop the grille and stuff a pillow in it.
That'll keep the noise out.

Have your local hvac contractor install a motorized damper 8-10' upstream of
the grill. Some better motoorized dampers have a rubber gasket inside for near
perfect positive shut off. Control the motorized damper with a toggle wall
switch. Been there, done that.
