When designing a kitchen ventilation system, many homeowners focus on factors like CFM, ducting, and materials. However, one crucial yet often overlooked detail is the depth of the blower. One common recommendation is to avoid using a blower that is less than 18 inches deep. But why is this very important? Below, we'll explore the reasons and how selecting the right blower depth can significantly impact your kitchen's air quality and efficiency.

Insufficient Smoke and Grease Capture
Ventilation efficiency depends on how well the blower directs and removes smoke, steam, and grease from your cooking space. Shallow blowers (<18") fundamentally fail at this critical task because they:

✖ Fails to create a proper capture zone- allowing cooking fumes to escape before being extracted.
✖ Disrupt airflow dynamics - unbalanced suction leads to weak and inconsistent ventilation
✖ Compromise duct performance - insufficient suction allows odors to linger and grease to accumulate

An 18" deep blower solves these issues by:
✓ Establishing a full capture envelope that contains all rising cooking vapors
✓ Maintaining laminar airflow for smooth, powerful extraction
✓ Optimizing duct system efficiency to fully exhaust contaminants

Increased Noise Levels
A shallow blower often needs to operate at higher speeds to compensate for its limited depth, leading to:

• Excessive noise - increased noise levels can make cooking less enjoyable and disrupt the kitchen environment.
• Motor Strain - running at higher speeds puts extra stress on the motor, reducing the longevity of the ventilation system.

Poor Ventilation for Large Cooktops
For wide or deep cooktops, a shallow blower can significantly reduce ventilation efficiency. It may:

• Fail to cover all burners – Incomplete coverage leads to uneven smoke and odor extraction, allowing fumes to linger in the kitchen.
• Struggle with high-heat cooking – Frying, grilling, and searing generate excessive smoke and grease, which require a deeper blower for effective removal.
• Allow steam and grease to escape – Inadequate capture results in poor air quality, increased residue buildup, and more frequent cleaning.

Long-Term Performance and Cost Efficiency
Although a shallow blower may appear to be a more affordable option upfront, it can result in higher costs over time due to:

• Frequent maintenance and cleaning – Poor ventilation causes grease buildup, requiring regular upkeep to maintain efficiency and hygiene.
• Higher energy consumption – Inefficient operation leads to higher energy consumption, increasing electricity costs over time.
• Premature part replacements – Operating at high speeds strains the motor, leading to quicker wear and potential breakdowns.

By investing in a deeper, high-quality blower, you ensure long-term reliability, reduced maintenance costs, and better energy efficiency, ultimately saving you money over the life of your custom kitchen hood.

Conclusion
Choosing the right blower depth is essential for maximizing your new range hood's efficiency, ensuring quiet operation, and maintaining a cleaner, safer kitchen. A blower less than 18 inches deep often leads to poor suction, excessive noise, and inefficient grease capture. At SINDA, we offer 18-inch deep blower options that are designed for optimal airflow, maximizing ventilation performance for your kitchen.
