HVAC Static Pressure Testing

Direct drive fans have fan wheels or blades that are attached directly to the shaft of the motor. Typically, the hood you purchase will dictate what CFM your exhaust fan will need to be. In other words, exhaust fans with a higher CFM need more energy efficiency. Fan loudness is generally expressed in sones. Let the experts at HoodFilters. Depending on the location of your exhaust fan, the sound generated by it may be a consideration. If the air in your system is encountering a lot of resistance, the static pressure increases. Factors affecting your hood choice include what type of cooking equipment you will use and the volume of cooking in your kitchen. If you need a low volume fan of 2, CFM or less with low static pressure of 0. On a direct drive commercial kitchen exhaust fan, the motor is mounted directly to the rotor shaft or fan axle. So which one is right for you? Understanding how these relate to your needs will help assist you in choosing the exhaust fan that is right for you. There are five main aspects to consider when choosing a commercial kitchen exhaust fan: model, static pressure, air volume flow rate, motor horsepower, and loudness. For high temperature applications, belt drive fans have the advantage of having the motor outside of the airstream. Direct drive fans, on the other hand, have a higher up front cost but will likely have fewer maintenance issues and lower upkeep costs for fan accessories such as supports, pulleys, and bearings. Here are some common guidelines for determining the minimum CFM of your commercial kitchen exhaust fan:. It really comes down to your budget and the specific needs of your ventilation system. Exhaust fans, ducts, filters β€” if one element is deficient, the entire system gets thrown off. For example, a rooftop exhaust fan typically requires a roof curb for proper installation. When it comes down to it, the horsepower of an exhaust fan motor relates directly to how much air can be moved with each watt of power output by the fan. Whereas a typical belt drive fan has five potential points of failure including belts, motor, shaft and pillow block bearing , a direct drive fan has only one β€” the motor. For ventilation applications, it is expressed in inches per feet of duct. For example, a large are of open flame wok cooking will require significantly more exhaust than the usual griddle or gas range. A properly designed and maintained system will provide years of service and significantly improve the environment in your kitchen and restaurant. Give us a call at {/INSERTKEYS}{/PARAGRAPH} Unfortunately, this loss of efficiency can be made even worse if the fan is not properly installed and maintained. Also referred to as system air resistance or friction loss, the static pressure in a system relies on all parts working properly. Should you get a belt drive fan or a direct drive fan? Watch this video to learn more about the upblast exhaust fans and accessories available at HoodFilters. Simply put, static pressure is the resistance against air as it travels through your ventilation system. Belts may need to be tightened, adjusted, and eventually replaced. Suggested levels of sones for a commercial kitchen are between 7 and 21 sones dBA. We depend on them to remove dust, dirt, grease-laden air, and smoke from our kitchens. Belt drive exhaust fans are less expensive, have higher speed motors, and allow more precise control of the fan speed. Additional advantages include fewer vibrations, lighter weight, and a more compact installation. {PARAGRAPH}{INSERTKEYS}All fans perform the same essential task β€” moving air from one place to another. As you can see, selecting the right equipment for your commercial kitchen ventilation system is extremely important. However, if your exhaust fan needs are above 2, CFM or you require static pressures above 0. Sones are an internationally recognized linear measurement equivalent to 40 phons. Where will you install your exhaust fan? Belt drive fans are driven by a belt and motor pulley system that is connected to the shaft of the motor. It is measured as air passes through a duct. Air velocity is measured in linear feet per minute, or LFM. As an example, an average refrigerator has a loudness of about 1 to 2 sones and a typical residential bathroom exhaust fan is about 2 to 5 sones. If exhaust fan noise is a concern for you, be sure to check the sone rating on the fan before purchasing. It relates to the status of equilibrium when the air supplied and the air exhausted are equal. In general, the higher the CFM, the higher the sone rating. Then, the LFM is multiplied by the volume of the duct in cubic feet to get a cubic feet per minute CFM measurement of air movement β€” also known as the air flow volume rate. One horsepower is equivalent to watts in the International System of Units. Where your fan is mounted will affect the housing of the fan and any accessories you may want to purchase along with it. Finding the right combination of CFM and horsepower for your exhaust fan will help make sure your ventilation system operates efficiently and with fewer maintenance issues. This makes a direct drive fan more efficient. Horsepower measures the power or energy that is output by the motor of your exhaust fan. The amount of power that a motor uses is not purely what it is capable of, but depends more on the manner in which it is loaded. And if the CFM of your fan is too high, your system will create to much static pressure which will cause air loss and wastes energy. As air pressure increased, the column of water in the manometer would rise. Static pressure is measured by a manometer, which originally used a column of water to show the amount of static pressure. Direct drive commercial kitchen exhaust fans are commonly considered more efficient than a belt drive fan. Sheaves and additional bearings in belt drive fans may increase points of mechanical failure. One of the first things to consider when selecting an exhaust fan model is the location you plan to install the fan. And as we mentioned earlier when we discussed direct drive vs. Direct drive fans also tend to require less maintenance and repair as they have fewer moving parts and components. But belt drive fans do have their advantages and are consistently and successfully employed in many commercial kitchen ventilation systems. Commercial kitchen exhaust fans are an essential part of your kitchen ventilation system. Shafts, pulleys, and pillow blocks must be correctly aligned. When your duct work and exhaust system are calculated properly, your system will run as it should. Most commercial kitchen exhaust fans are designed to be mounted in one of three locations: rooftop, wall mount, or in the duct. Speeds can also easily be adjusted in the field using pulley changes. Getting an accurate static pressure measurement is critical to selecting the proper exhaust fan. But if the CFM of your commercial kitchen exhaust fan is too low, you will likely have poor circulation and air distribution. That is why static pressure is still measured in inches of water. Lower exhaust air volumes are permitted during no-load cooking conditions as long as they are sufficient to capture and remove flue gases and residual vapors from cooking equipment. One pound per square inch is equivalent to The main ventilation system components directly affecting static pressure are duct surface material, the length of the duct, duct system design, and the volume of air being pushed through.
