Proper ventilation is one of the most important factors in a kitchen.
As professional stoves increase higher BTU output, there is an important need for more powerful venting.
Professional hoods help to remove smoke, steam, and odors produced when cooking.
Professional hoods tend to be larger and deeper to compliment professional style ranges. The blower can be available in three ways– internal, in-line and external. Most blowers start at 600–1,500 CFM.
An internal blower is built inside of the hood, while an in-line blower is installed into attics, and external blowers are outside of the house.
What makes a professional hood effective?
Professional hoods are design at 18” tall and 24" to 27" deep. The height of the hood can trap and hold odor before exhausting. The depth will cover the burner heat, as well as grease splatters.
Professional hoods usually are available with stainless steel screens or baffle filters. Screen filters are lighter but require cleaning more often. Baffle filters are worth the upgrade because they are sturdier, absorb more grease and allow more air to be exhausted. Regardless of how the filters are made both are dishwasher safe.
Rules of Thumb for Proper Venting
- For every 10,000 BTU you need approximately 100 CFM
- Decide where to mount blower. We like internal blowers, because they are easier to fix and you dont have a huge blower on your house
- Proper mounting of hood is approximately 30”- 36” height
- Width of hood should at least match range size
- Determine the length of duct work for proper blower. Duct runs should be straight. Bending reduces efficiency considerably
- Determine duct size for proper air movement, and create less static pressure. We recommend 8-10 inch round duct
External Blowers vs. Wall Caps
Which Brands to Purchase?
The easiest way to purchase a professional hood is to match the brand of the stove purchased.
It is always nice to combine with the same brands, which will have the same look or texture. Broan, Zephyr, Wolf, Viking, and Thermador are major hood manufacturers.
But you can save a lot of money by going with a noncommercial brand name. Yale exclusive custom hoods are a good value, because the blower is already installed in the hood, and has a natural, no logo look to match with any stove.
