HOW TO CHOOSE THE RANGE HOOD VENTILATION FOR YOUR KITCHEN
Selecting the proper ventilation system is the most critical step in designing an efficient and clean kitchen. At Fobest, we offer three distinct ventilation paths engineered for performance, durability, and style.
Quick Comparison: Ventilation at a Glance
| Feature | Internal Motor | Remote Blower | Ductless Conversion |
| Location | Inside the Hood | In the Attic/Roof | Recirculating (No Duct) |
| Max Airflow | Up to 1260 CFM | Constant 1260 CFM | ~395 CFM |
| Noise Level | Standard (68-70dB) | Ultra-Quiet | Standard (67dB) |
| Best For | High Performance | Open-Concept Homes | Apartments/Condos |
1. Internal Motor (Motor In The Hood)
The Internal Motor is the industry standard, where the blower system is integrated directly into the hood liner.
-Powerful Suction: Available in configurations ranging from 600 CFM to 1260 CFM.
-Convenience: Easier to install and maintain as all components are accessible within the kitchen.
-Ideal For: Homeowners who want a professional-grade exhaust system with a straightforward installation process.
2. Remote Blower (Motor In The Attic)
By moving the motor away from the kitchen and into the attic or roof space, we drastically reduce ambient noise without sacrificing an ounce of power.
-Silent Performance: You only hear the rush of air, not the mechanical hum of the motor.
-Maximum Airflow: Optimized for large kitchens, delivering a consistent 1260 CFM across all hood sizes (36" to 60").
-Ideal For: Open-concept living areas and gourmet kitchens where conversation and peace are just as important as the cooking.
3. Ductless Conversion (Recirculating Option)
For homes where exterior ducting isn't an option—such as high-rise condos or historic renovations—the Ductless Conversion is the perfect alternative.
-Air Purification: Uses advanced charcoal filters to scrub grease and odors before recirculating clean air back into the kitchen.
-No Renovations Needed: Skip the wall and roof cutting; this system is designed for simple, non-invasive setups.
-Ideal For: Apartment dwellers and kitchens without access to external venting.
Understanding the Specs: Sizing Your Ventilation
Choosing the right CFM (Cubic Feet per Minute) depends on your range hood size and cooking style. Below are the technical standards for our vent systems:
For 30" & 36" Hoods
-Internal Option: 600 CFM (Requires 6" Round Ducting)
-Remote Option: 1260 CFM (Requires 8" Round Ducting)
-Lighting: 2 x 3W LED Lights for focused task lighting.
For 42", 48", 54" & 60" Hoods
-High-Volume Airflow: Up to 1260 CFM to handle high-BTU professional ranges.
-Expanded Illumination: 4 x 3W LED Lights to cover the entire cooking surface.
-Ducting: Requires 8" Round top venting to ensure peak efficiency.
How to Choose the Right CFM for Your Range Hood
CFM (Cubic Feet per Minute) measures the air volume your hood moves. To find your ideal match, consider your stove type and cooking habits:
-Gas Ranges: You need 100 CFM for every 10,000 BTUs of total burner output. A high-output 60,000 BTU stove requires at least 600 CFM.
-Electric Ranges: A general rule is 10 CFM per inch of stove width. For a 30" cooktop, a 300 CFM motor is sufficient.
-High-Heat Cooking: If you frequently sear, fry, or use a wok, we recommend upgrading to our 1200+ CFM internal or remote blower options to ensure smoke and grease are cleared instantly.

Frequently Asked Questions (FAQ)
Q: What duct size do I need for a 1260 CFM motor? A: For high-airflow motors (1150-1260 CFM), an 8-inch round duct is required to prevent backpressure and excessive noise.
Q: Is a higher CFM always better for my kitchen? A: Not necessarily. While higher CFM provides more power, it’s important to match it to your stove’s heat output. A 1200+ CFM motor is perfect for high-BTU professional gas ranges, whereas 600 CFM is often the "sweet spot" for standard daily cooking, balancing high efficiency with lower energy consumption.
Q: How high should the hood be installed? A: For optimal performance, the hood should be installed between 30” to 36” above the cooking surface.
