## Questions & Answers

**Q: what is the maximum thickness of the door this vent can accommodate?**
A: Hi Bob, thank you for the inquiry. Our grilles can be installed in doors of any thickness as long as there are screws long enough. Screws that come in the box are just under 40 mm long (roughly 1 1/2 inch). I hope  this answers your question. Regards, Engera Team.

**Q: what is the net free area (NFA) of this grill?**
A: Hi John, the NFA of this grille is approx. 0.015 sqm which is roughly 37% of the face grille area (calculated with the flanges). Hope this helps! Regards from Engera!

**Q: Will this work on a pocket door with out causing opening and closing issues?**
A: Hi and thank you for the inquiry. It depends on how the doors close/open. if they slide then it may not work if the gap between the door and the inside is too small as the grille is not completely flushed with the door surface.. Can you send us a picture of the door you have, we are happy to have a look and advise? All the Best Engera Team.

**Q: I want to put these at the top of 2 bedroom doors. How would I install them and what could I put between them to block sound and keep air flow?**
A: Hi and thanks for your inquiry. Always happy to assist,  If this is for the natural ventilation (no mechanical - fan forced -exhaust system etc) then we are afraid that anything you will place to stop the noise transfer will affect th airflow, most likely making the whole process pointelss. if there is a mech system involved, then you can try to cut a piece of foam based air filter, similar to what is used in the vacuum cleaners to stop the noise whilst still making it all breathable. Note that depending on your fan capacity (static pressure) this may work satisfactory or less, depending on how tick is the acoustic layer and the relative fan spare capacity.  No straight answer here, sorry for that.  Acoustically the best solution would be to connect the bedroom with the corridor via in ceiling piece of duct and two ceiling mounted grilles. in terms of the installation, you make a cutout in the door and tight the two pieces together using screws which come with the grilles. hope this gives you some direction! All the best with your works! Engera Team!

### ⭐⭐⭐⭐⭐ Good product
*by G***E on October 3, 2025*

Easy to install. Keeps the mist from staying in the bathroom.

### ⭐⭐⭐⭐⭐ Fit our door perfectly!
*by J***E on September 5, 2025*

I had to hire someone to install it because I didn't have the tools to cut into my door but it turned out really well.

### ⭐⭐⭐⭐⭐ Good air flow and still private
*by F***H on January 4, 2025*

Being a perfectionist, I cut a specific hole for each side of the vent. You probably don't have to (and on a solid door you can't) since the flange lip is wide enough to bridge the gap if cut carefully (one side has a smaller perimeter than the other as the one piece fits inside the other.) The other comments about the terrible screws supplied have a simple explanation. The head on the screws is the European Phillips head, not the #2 we're used to in the States. If you're careful, you can make a #2 work (or even a small flathead,) but for me, 68 cents later I had two replacement screws in stainless from Ace hardware. No big deal. As with all plastic items, ensure the fit is flush before torquing the screws down and only enough to seat the vent in the door. A swiffer type brush cleans the vent quite nicely. After I installed it, my family thought I had bought a whole new door
