10 Tips for Commercial Centrifugal Fans - from Ventto Manufacturer
Toby plans to buy industrial centrifugal fans. It can exhaust oil smoke for his commercial kitchen. He is tired of the complaints from the chefs, the fines from the environmental protection department, and the feeling of being choked by oil smoke. Toby runs a Chinese restaurant that mainly serves Asian food, teppanyaki, and fried food.
His commercial kitchen is a place where oil smoke stays. If you have been to his commercial kitchen, you will see smoke-blackened walls, greasy smoke pipes, and haggard chefs. Diners are reluctant to dine in such restaurants, except for the frequent patrons of environmental protection department staff.
Toby sent us a rescue message. He trusted our identity - commercial ventilation equipment manufacturer. We are
Ventto, a commercial ventilation equipment manufacturer from China. Ventto has 23 years of experience manufacturing commercial exhaust hoods, electrostatic Air precipitators, and industrial centrifugal blower fans.
Types of commercial centrifugal fans
When you walk into the factory of a vent to a commercial ventilation equipment manufacturer. You will see two types of commercial centrifugal fans. One type looks like a huge iron cage, and the other looks like a giant snail.
What is the difference between these two types of commercial centrifugal fans? What are their advantages and disadvantages? Which commercial centrifugal fan is more suitable for my commercial kitchen? Many questions are arising in your mind. Then, look at me. I will give you the answers.
Its appearance looks like a huge iron cage. It is the natural enemy of commercial kitchen fumes. It can absorb and discharge 1967m³ to 108252m³ of fumes per hour. You can always believe in its ability. It is a good helper.
You can see it on the roof, on the ground, or in the warehouse. It is very large and is not suitable for hanging on the wall, ceiling, or other high-altitude locations. In short. If your commercial kitchen has enough space to place it, your commercial kitchen produces a lot of fumes per hour. You can choose a cabinet-type commercial centrifugal fan.
It looks like a giant snail shell. It looks cute, but please don't ignore its ability to absorb and discharge oil smoke. Its volute can absorb and discharge 1370m³ to 21330m³ of oil smoke per hour. It is a transfer station for kitchen oil smoke, and any wisp of oil smoke must pass through it to go outdoors.
Commercial centrifugal Air blowers on the roof, ceiling, wall, or ground. It is small in size. It can be embedded in compact commercial kitchens, food trucks, cafes, and backyard barbecue parties. It is charming and powerful commercial ventilation equipment.
Impeller types of commercial centrifugal fans
Above, we have learned about cabinet-type commercial centrifugal fans and industrial centrifugal Air blowers. There are two types of commercial exhaust fans. The journey of exploring more knowledge about commercial ventilation equipment is not over yet.
If you look a little closer at the structure of a commercial centrifugal fan, you will find something interesting. Please pay attention to the impeller of the commercial centrifugal fan. There is an impeller that looks like a washing machine drum (forward-inclined impeller), and there is an impeller that looks like a plow wheel (backward-inclined impeller).
(1) Forward Blade Impeller
The inclination angle of the forward-inclined impeller is greater than 90°. At the same rotation speed, the centrifugal force generated by the forward-inclined commercial centrifugal fan is less than that of the backward-inclined commercial centrifugal fan. It means that the forward-inclined commercial centrifugal fan emits less oil smoke than the backward-curved centrifugal fan.
(2) Backward Blade Impeller
At the same rotation speed, the pressure difference generated by the forward-inclined commercial centrifugal fan is less than that of the backward-inclined commercial centrifugal fan. This means that in a high-pressure environment, the forward-curved commercial centrifugal fan is more stable than the backward-curved commercial centrifugal fan.
How to calculate the amount of oil smoke in commercial kitchens.
I often tell restaurant owners that before they decide to buy a commercial centrifugal fan. Please tell me the exhaust volume of their commercial kitchen per hour. This answer determines whether you can buy the right commercial centrifugal fan. I have to correct a misconception. It is not necessarily the expensive, large-displacement, and big-brand commercial centrifugal fans that are the best. Only the commercial centrifugal fans that perfectly match your needs are the best.
The amount of oil smoke in commercial kitchens is a necessary factor. In the product parameters of commercial centrifugal fans, CFM represents the air volume it can exhaust per hour. This value should be greater than or equal to the amount of oil smoke in commercial kitchens. It is the simplest purchase technique.
Calculation formula for oil smoke volume
How should I calculate the amount of oil smoke in commercial kitchens? Is there a calculation formula for it? Of course. Let's choose the most obvious reference. Take the number of burners as a reference. According to the test of the vent to commercial ventilation equipment manufacturer, each burner produces an average of 3,000m³ of oil smoke per hour. Please count how many burners are in your commercial kitchen. Multiply the number of burners by 3,000 to get the commercial centrifugal fan exhaust volume you need.
Toby's commercial kitchen has a commercial Chinese 2-wok range, a commercial induction soup cooker, a commercial induction food steamer, a conventional baking oven, and a commercial double fryer. It means that Toby's commercial kitchen will produce 7*3,000m³ (21,000m³) of oil smoke per hour. Ventto commercial ventilation equipment manufacturer recommended Toby buy a 21,000 CFM commercial centrifugal blower fan.
Should I choose a silent commercial centrifugal fan?
I don't want to have the sound of the commercial centrifugal fan running in my ears when I'm cooking or eating. It makes me upset. Unfortunately, the commercial centrifugal fan will make some noise during operation. It's inevitable. Just like you make some noise when you walk or eat. It's normal.
You can reduce the noise generated by the commercial centrifugal fan in some ways. For example, you can buy a silent commercial centrifugal blower fan. The commercial centrifugal blower fan of Ventto commercial ventilation equipment manufacturer is a low-noise type.
How did the Ventto manufacturer do it?
Before answering this question, we should understand the structure of the commercial centrifugal fan. It consists of a stainless steel snail shell, an impeller, a belt, and a motor. Among these parts, the impeller, belt, and motor are the sources of noise.
After the Ventto manufacturer corrected the static and dynamic pressure balance between the impeller and the belt, the commercial centrifugal blower fan produced a lower volume of noise during operation. The outer shell of the Ventto commercial centrifugal blower fan is made of thick stainless steel. It can isolate most of the noise.
I want to tell you a way to choose a silent commercial centrifugal fan faster. Do you want to know? Please read on. As mentioned above, the impeller of the forward-inclined blower is a drum type. It has a higher blade tip speed, which is the source of high noise. The blades of the backward-inclined blower have a cushion when transmitting air. It can reduce noise.
Where do you use the commercial centrifugal blower fan?
This is a critical question. It determines which commercial centrifugal blower is more suitable for you. If you are looking for ventilation equipment for knitwear factories or chemical industries, you can consider commercial centrifugal fans for dust, smoke, and cooling.
(1) Commercial Kitchen
If you are looking for a commercial centrifugal blower for commercial kitchens to remove fumes and odors produced during cooking. You can buy a vent to a commercial centrifugal oil fume fan.
(2) HVAC System
If you are looking for ventilation equipment for air circulation and temperature regulation for air conditioning systems (HVAC), you can consider a commercial electrostatic air purifier or commercial centrifugal Air blower.
Ventto commercial centrifugal blower fan helps extract car exhaust and ventilate underground garages or tunnels. In agricultural planting, commercial centrifugal fans can adjust the temperature of greenhouses and extract odors. In warehouses or logistics and transportation centers, commercial centrifugal fans can reduce temperature and humidity.
