Buying a chimney requires some research on what type of chimney is required for our home. I spent nearly six months trying to figure out what chimney to buy. Once its decided what brand then comes the problem of suction power. Honestly its very difficult to decide what suction power is required for what type of kitchen.
After some googling and going through the some of the technical specification i figured that the suction power depends on the following factors.
- Kitchen Size: If you have a large kitchen then the amount of air sucked in will be more. Therefore, you will require a large suction capacity.
- Cooking style: If you cook more oily food then more suction power is required. The density of smoke will be high if you cook oily food. Hence, lower suction chimney will lead to oil dripping from the hood.
- Duct length: The length of duct plays a very important role when selecting the suction power. It your chimney is too far from the exhaust hole then you probably would require to use a long aluminium duct to make sure the smoke reaches outside. In that case you will have to use a higher suction power chimney for better efficiency.
In normal cases these are the reference for chimney suction power
- low to medium oil usage: 800 to 1000 m3/hr
- high oil usage: 1200m3/hr.
Please note that the chimney fan speed can be varied from the panel provided ,so it is better to buy a higher power chimney and adjust fan speed as per cooking need.
