Kitchen Dual Inlet Blowers

Kitchen fume emissions are becoming a major concern in the rapidly expanding catering sector. The global market for kitchen ventilation systems is expected to expand at a compound annual growth rate (CAGR) of 6.4%, from $4.51 billion in 2025 to $7.79 billion in 2034. In the meanwhile, the recently updated "Emission Standard for Catering Industry Fume" has raised the bar for noise control, purification rate, and exhaust efficiency. Blauberg has introduced Dual Inlet Blower fan that offers an integrated high-performance centrifugal fan solution for kitchen fume extraction at this crucial point of industry transition by utilizing its fundamental German technological advantages.

Blauberg's Industrial Fans business, a top producer of ventilation equipment worldwide, is dedicated to offering a complete range of products, including axial and centrifugal fans, covering a variety of applications such heavy equipment cooling, HVAC, and industrial ventilation systems. The recently introduced Dual Inlet Blower series is the result of the group's years of technological accumulation in the ventilation area, and it has over 700 international patents.

The Dual-Inlet Fan is the Best Choice for Kitchen Fume Exhaust

Dual-inlet blower fan is a centrifugal fan that has air intakes on both sides of the impeller. Air simultaneously enters the impeller from both sides, concentrates, is driven by the volute, and then leaves through the outlet. It has a complete advantage over single-inlet volute fans in managing kitchen odors because of its structural construction.

The dual-side air intake's greater airflow impact is, in theory, completely used by the dual-inlet volute fan. It simultaneously achieves a triple balance of high air pressure, big air volume, and low noise through enhanced volute flow channels and impeller aerodynamic design. The Blauberg Dual Inlet Blower fan is particularly suitable for complicated kitchen situations where it is necessary to overcome many resistances from fire dampers, elbow ducts, and fume hoods. Compared to conventional single-inlet fans, it has a more uniform airflow distribution, reduced vibration, and a 40% increase in airflow at the same rotating speed.

Why Select dual inlet fans: Four Principal Benefits

1. Greater Airflow, More Complete Elimination of Smoke

Everyone's health and the working environment are directly impacted by how quickly kitchen gasses are expelled. Our dual-intake volute fan efficiently draws in vapors from two inlets at once by allowing air to enter from both sides. The volume and area of the air intake are increased as a result. It produces a greater exhaust volume, extracts fumes more quickly, and eliminates them more successfully than a single-intake centrifugal fan with the same impeller size and rotation speed.

2. Increased Energy Efficiency Driven by EC Motor Technology

Energy expenses are a major problem since commercial kitchen fans sometimes need to run continuously for long periods of time. An EC (Electrically Commutated) brushless DC motor is an option for the Blauberg double inlet blower fan. EC motors can reduce power consumption by up to 70% when compared to conventional AC fans. By using electronic commutation technology to eliminate brush friction losses, Blauberg's in-house EC motor maintains over 85% efficiency even under partial load situations, improving efficiency by 25% to 30% over conventional induction motors. In the meanwhile, the EC motor offers 0-10VDC/PWM dual-mode stepless speed regulation, which enables "ventilation on demand" and prevents energy loss from fixed-speed operation by adjusting the air volume in real time based on the actual oil fume concentration in the kitchen.

3. A Better Kitchen Environment with Less Noise

Due to their enormous volume, traditional kitchen fans frequently generate issues for their operators, particularly in restaurants housed in residential buildings where noise complaints are frequent. The structural design of dual-intake volute fans naturally reduces noise since intake from both sides guarantees a more uniform and stable airflow distribution, which lowers turbulence and impact losses during intake and exhaust. When combined with Blauberg's triple noise reduction technology (noise-reducing holes, sound-insulating materials, and optimized volute design), the Blauberg double inlet blower fans' operating noise can be controlled between 53 and 57 dB(A), which is significantly lower than the industry average and makes working in the kitchen more comfortable.

Which type of volute fan is better for  kitchens, a single-inlet or a double-inlet?

To help customers make more informed decisions, we provide a comprehensive comparison of single-inlet and double inlet blower fans from several perspectives. In addition to  kitchens, our clients may select the best fan for their sector.

Airflow: Due to its single intake, single inlet blowers provide modest airflow. Double inlet blowers are better suited for medium-sized to large-sized  kitchens with larger exhaust volume needs since they feature two inlets that increase airflow by around 40% at the same rotating speed.

Pressure: For high-rise smoke extraction or long-distance ducting, single inlet blower fans provide higher pressure. Because of their superior volute flow channel design,double inlet blower fans also perform very well in terms of pressure, sustaining stable operation at medium to high static pressure circumstances (845Pa).

Noise Level: By using cutting-edge aerodynamic design and noise reduction technologies, our double inlet centrifugal blower fan has greatly reduced its noise level, consistently enhancing its overall noise management capabilities.

Maintenance and Cleaning: double inlet centrifugal blowers usually have a bottom drain outlet (oil valve) that permits condensed waste oil to naturally flow along the curved casing to the bottom for discharge, reducing buildup. The impeller design also makes cleaning and disassembly easier.

Blauberg's IoT-Enabled Solutions for the Smart Kitchen Era

Intelligent technology is becoming a necessary trend for effective kitchen ventilation as the industry speeds up its transition to "fully automated, low-emission, and highly integrated" systems. Blauberg's double inlet centrifugal fan seamlessly interacts with Industry 4.0 platforms and smart home systems thanks to an integrated IoT-ready controller that supports the RS485 communication standard. In order to provide intelligent smoke control, energy management, and predictive maintenance, the fan may modify operating settings in real time depending on sensor data. This lowers operational expenses for catering companies while satisfying ever-tougher environmental regulations.

Intelligent ventilation solutions are quickly becoming more and more popular in the global market for kitchen ventilation systems. Innovative technologies like demand-controlled variable speed fans, IoT-enabled real-time air quality monitoring systems, and heat recovery devices are being adopted at an increasing rate. A standard device that fits this technical trend is Blauberg's dual-inlet volute fan.

Blauberg double inlet double with centrifugal fans are utilized in key areas of  kitchens, such as star-rated hotel kitchens, central kitchens, chain fast food restaurants, school canteens, large supermarket food courts, and hospital catering centers. They have a broad range of applications and promising global market prospects. Customers both domestically and abroad have acknowledged the product performance and technical dependability of this series of centrifugal fans, which are also widely used in air conditioning systems, purification equipment, industrial ventilation, refrigeration equipment, and fresh air units.

According to market research, as the global QSR (fast food) business grows and indoor air quality regulations tighten, the  kitchen ventilation system market will continue to rise quickly. Using a four-in-one technological innovation approach—high efficiency, energy saving, quiet operation, and intelligent technology—Blauberg will continue to capitalize on its German technological heritage and localized manufacturing advantages to offer top-notch centrifugal fan products and ventilation solutions to customers worldwide.
