| #1 | Q: So this if for exhaust and intake. Do I just remove the damper for intake? A: That is exactly how it is used for intake. The damper is removable. Asked on 2023-05-10 by Simon |

| #2 | Q: Is this compatible with a range hood with 1200 CFM? Will have 8 inch duct. A: Its compatible with typical 8 inch duct airflows which are 500 to 850 cfm. You will have a large pressure drop trying to push 1200 cfm through and 8 inch duct and 8 inch cap. Asked on 2021-07-04 by Ashley |
| #3 | Q: How much heat can these withstand? I am looking to vent a hood for an outdoor kitchen (Propane grill) through the soffit to avoid putting holes in the patio roof. A: There is no official rating from the manufacturer but they are designed to vent typical HVAC exhaust air streams. Normally up to 140 F. Asked on 2021-06-23 by Don |
| #4 | Q: looking for SV28 without the screen (SV28NS) to utilize for a dryer vent. It does not appear you carry this model. Is the screen that comes on the SV28 removable? A: We do not carry the SV28NS version. Sorry. The screen is not removable. Asked on 2021-02-02 by RM |
| #5 | Q: 1.What is the length of the snap in adapter?2. Can this vent works with 70 cfm air flow pressure of bathroom exhaust fan? A: The adapter is 4 inches long. That vent should be fine with that cfm and opens easily. Asked on 2020-11-22 by V P |
| #6 | Q: I have an older home and the exhaust pipe is 3 diameter metal. Do you have a 3 to 4 adapter that will allow me to use the SV28 Soffit Exhaust Vent? A: We do not. Sorry. That is no longer a common size. Asked on 2020-06-03 by WB |
| #7 | Q: Is this supposed to be screwed into the bottom of the soffit where the flaneIs visible? Or can we install inside the soffit, cut a square the. Drop the vent through the hole?The large flange is a bit unsightly, if installed on the outside of the soffit we can trim away. Also, the unit says do not install beyond soffit, can you guys elaborate or post a photo of one of these installed? A: It can be installed inside the soffit.

| #8 | Q: Can this handle 400 cfm air flow for an exhaust fan? A: Yes. That is within the allowed CFM for these. Asked on 2019-12-31 by Matt |
| #9 | Q: I bought the SV28-01 with the RV28-4 adapter. I dont think it will come in time for my contractor to install it for me. I would have to have him drill the hole at least so that once it comes in, I can just insert it. I cant find the instructions for what size hole to drill in the soffit. Can you point me to something? Also, is the adapter I bought meant for soffit instillation or something else? A: The RV28-4 converts the square opening to round for a duct connection. I would show your contractor the spec sheet which has the base dimension. They should be able to figure it out based on that. https://www.hvacquick.com/catalog_files/Primex_SV28_Specs.pdf Asked on 2019-09-02 by Eddie |
| #10 | Q: My soffit has a 5.5 / 12 pitch. Would the door be in closed position in the normal fan off situation? A: No. This soffit vent is meant for horizontal installation. If you install on a pitched soffit, the door would not close properly. Asked on 2019-08-12 by Tony |
| #11 | Q: Can I cut the flange down? A: Yes, you can trim the flange as needed. Asked on 2019-05-26 by Pete |
| #12 | Q: Is this vent paintable? A: Yes it is a paintable plastic. Asked on 2018-03-10 by Larry |
| #13 | Q: Im looking for the snap in adapters (sold separately) for the sv28-01 soffit vent in 8 in duct. A: Same page, couple of lines below the SV28-01. Part number RV28-# where # is the duct connection size. Asked on 2017-04-19 by Christopher |
