The general consensus is that a round channel is more efficient and cost -effective than a rectangular channel. Air systems with round channels have less air resistance because they use less metal than rectangular duct systems. This also means that the round channel is a cheaper option.

If you have already purchased your hood, you are probably here because your kitchen hood doesn't work well. This can be due to the existence of an oil hood. Unfortunately, cleaning this channel can be very difficult and time consuming, and sometimes replacement will cost you less.

Along with the size of the channel, the length of your channel is important to consider. In some cases, even if your duct is slightly smaller, if you have a very short or longitudinal duct, you can still drain the cooking air effectively. First, a shorter channel is always better. This means that your air needs less quickly to get out. Next, the lower the bending, the better. Each time you change the direction of your channel, you add more resistance and pressure to the outlet air. Reducing your channel length can be more resistant. We do not recommend running more than 2 meters. From there, reducing our standard length for any bending or knee is 2 degrees in your duct. So if you have a curvature, your maximum hood length should not be more than 2 meters. And finally, as hot air rises, up -to -date canal is always the best way to enter the kitchen. This will help the air get out of your house faster.
