  • Designed specifically to be compatible with most conventional and commercial style cooktops, combines a sensational appearance with high performance features. Stainless steel construction on all exposed surfaces provides a durable finish and an unforgettable look. (Insufficient space for built-in ovens)

    • Compact design is installed directly behind the cooktop for an unobtrusive appearance. (Not for use behind ovens.) Thin profile saves precious space under the cabinet
    • Chimney rises over 9-1/2 inches when activated, ideal for large pots and pans
    • Infinitely adjustable control is designed to provide convenient access to govern the blower speed for effective and quiet operation
    • Optional remote control will activate down draft from an alternate location (RMDDRBK sold separately)
    • Dishwasher-safe filters are easy to remove and feature a stylish brushed stainless steel appearance for a professional look
    • Unique ducting capability allows the internal blower connection to be ducted to the left, right or downward (from left to right)
    • Heat Sentry adjusts speed of blower to high automatically in case of excess heat, to prolong product life
    • Compatible with optional Broan Make-up Air Dampers (MD6TU or MD8TU, sold separately) to fit 6" or 8" ducting and help to balance the air pressure when the range hood is in use, keeping your environment comfortable

  • RMDD4804 is rated 4.2 out of 5 by 9.
    Rated 4 out of 5 by from Works well, Installation not the easiest, could have better manual Works well but still dealing with some housing vibration noise. Unless you measure everything in the store, you will not realize how big this unit is and how much room it takes in the cabinet until you take it out of the box. It will work best with an extra deep or open back/open side cabinet. From the installation manual, I just was not sure I had the cutout right until I actually put the blower in place. (By the way - it is heavy.) Even after reading the install manual on electrical placement, I still ended up moving the plug in box.. Unless your gas line is already in place for the cooktop, wait to run it until you have the blower installed.

    Rated 4 out of 5 by from OVerall Good value Works extremely well and consistently except one of the 6 burners does not function well. It sort of explodes heat. But the other five work perfectly.

    Rated 5 out of 5 by from Excellent product. Love the easy operation and attractive look. The downdraft functions excellent taking smoke and fumes out of my kitchen. The attractive style looks fabulous on my center island. Operates great and not too noisy even with fan on high. I love this product and would recommend it.

    Rated 5 out of 5 by from Good product and good styling Great value compared to upper end name brand downdrafts. Quality and noise are good.

    Rated 4 out of 5 by from good vent wish it was a little taller, when using gas stovetop front burner it will not catch all the smoke as it is not quite tall enough and our very sensitive smoke alarm will go off...if you don't have cathedral ceilings & use the back burner it'd be perfect!

    Rated 4 out of 5 by from Exhausts effectively, but noisy. Installation was not easy. The vent is noisier than I expected, especially at high speed exhaust. Fortunately the fan speed and noise can be adjusted. Insatallation was challenging. I was very difficult to attach the ductwork because there was so little space beloww and behind the unit. Also, the dimensions given do NOT include the 1/2" bolts sticking out of the back of the unit. The cabinet had to be cut away partly in back to allow for the extra space.

    Rated 3 out of 5 by from Not included the remote button For the price you pay they should include the remote button with the unit. $1600.00 dollars later I had to call and order the 62.00 remote button. My mother is 4' 5" and no way could she lean over the stove to turn on the unit. This is a no brainer if you are spending that amount of money include the little remote button. It was a hassle and held up our construction and counter tops for a week waiting on this part.

    Rated 4 out of 5 by from It fit! Bought this Broan downdraft as a replacement for an old Dacor downdraft, primarily because it fit. Pleasantly surprised, the quality seems to be quite good. Only wish I had the flow restrictor installed. With a very short exhaust, even low is a somewhat more than expected. Hope it lasts a long time.

  • External venting

    In my home routing ductwork outside of the house will be very difficult. Is the product suitable for internal venting?
    Asked by: Anonymous
    Thank you for your question on the model RMDD4804 down draft kitchen exhaust system. The RMDD4804 does not offer a non-ducting option. It must be installed with duct work going completely outside.

    Is there a 48" downdraft that is recirculating and not ducted?

    Asked by: Anonymous

The D49M or Cattura can be seen on the BEST website at www.bestrangehoods.com. If you have any questions about this model, please contact our Technical Support directly at 800-637-1453.

    Can I put a a RMDD3004 behind a cooktop that is going to be put in a cabinet that goes against the wall.

    I want to put the downdraft vent in a cabinet that is not in an island.
    Asked by: Anonymous
    Thank you for your question on the model RMDD3004 down draft kitchen exhaust system. The RMDD3004 is designed to be installed in a standard depth cabinet with a drop-in cooktop. It does not need to be an island installation. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

    How do I clean this product?

    Have lost the user guide. Can I find one to print so I can find out how to clean it other than the filters?

    I have a slide-in stove with a 9" deep raised shelf behind, 9" of void under shelf behind stove. Can I make this unit work?

    My situation is almost exactly like the picture on this web page, except that instead of a cooktop, mine is a full range with ovens under, so the fan of this blower would need to be mounted on the rear facing face of the duct. Is this possible? Is there another downdraft blower that would work for me?

    Thank you for your question on the model RMDD3604 down draft kitchen exhaust system. The RMDD3604 is only designed to work with a drop in cook top. It will not install properly with a slide in stove.
