Delta Electronics VFB25AX Reviews

Rated 4 out of 5 by from Excellent service While the response and service were excellent, the product is adequate. It is a second fan in a steam bath and shower and the fan's performance is not what was hoped for. Overall, we are happy with the purchase and would still recommend the site to friends and would use it again.

Rated 5 out of 5 by from Nice 2-speed option - and quiet! The fan was really easy to install and works well. I really like how quiet it is at the normal speed, and the indicator LED behind the grill that lets you know visually what speed you are running the fan. The quick on-off at the wall switch to activate the speed switching electronics in the fan is a great idea and - along with the visual clue of the LED color - is a nice combination.

  • Can this fan be used with timer switch?

    A. Thank you for your question. Yes, the Delta Electronics VFB25AX can be used with a timer switch. Please let me know if you have any further questions.
  • can i attach something that tells it to engage at the lower speed when a certain temperature is reached

    A. Thank you for contacting us regarding the Delta Electronics VFB25AX. I am not aware of any such device from Delta Electronics that can operate they way you describe. There may be a much more sophisticated product out their in the marketplace for commercial applications that functions like that but I would not know where to direct you to find that. Sorry. Take care and have a good weekend!
  • Can the Delta Electronics VFB25AX? be wall mounted and can it be painted?

    A. The Delta Electronics VFB25AX can be wall mounted and you can paint it if you would like.
  • Do you need a special switch because this is two speeds?

    A. No, most switches we carry will enable both speeds to be used.
  • How does the fan get switched between low and high speed?

    A. The Delta Electronics VFB25AX is controlled via a normal hardwired wall switch; when switched off, and then on, it changes speeds. A colored LED indicates which speed it is currently on.
  • When will this fan with a light be available? I saw this fixture at the San Francisco PCBC show in June. You have an office right here in Fremont, CA. Any chance of an advance sale?

    A. The Delta Electronics VFB25AX with a light will be available early in 2011 (with a new model number). As soon as we have ship dates, it will be on our website to order!
