Why Maintain Your Restaurant Exhaust Fan?

Posted on November 28th, 2007 in Industrial by fan

Dining out means more than just satisfying a hungry stomach to a lot of people. In many cultures, the restaurant serves as the unofficial venue for cementing relationships, closing a business deal or establishing a lasting bond with friends and relatives. In many ways, the restaurant becomes the second home or second office of its customers. That is why the restaurant owner who intends to stay long in the business strives to provide his customers good food, excellent service, clean and comfortable surroundings. To achieve this, he has to have a great kitchen crew; a courteous wait staff and a well maintained restaurant exhaust fan system.

Perhaps, you are wondering what a restaurant exhaust fan got to do with satisfying customers. When the indoor air in a restaurant is stale and stuffy or polluted with cigarette smoke and cooking fumes, the customers become uncomfortable, and no matter how good the service or delicious the food is, they tend to lose their appetite. And the next time around that they go out to eat, they will certainly go elsewhere. The simple installation of a restaurant exhaust fan to vent the dining room and kitchen will do wonders in the quality of indoor air in the restaurant and in making for happy plates.

A restaurant exhaust fan comes in different types and brands. An “in-line” exhaust fan is installed in the exhaust duct, which is located inside the restaurant. This type of exhaust fan is used when it can not be mounted anywhere outside the restaurant. An “upblast” exhaust fan, on the other hand, is installed directly on top of the exhaust stack, which goes all the way from the kitchen to the roof of the restaurant. A restaurant exhaust fan for kitchen ventilation must be strong and durable enough to withstand hot streams of grease laden air from the ovens.

As a result of the constant exposure of the restaurant exhaust fan to cooking gasses, grease builds up on the fan affecting its efficiency and become a fire hazard. Chunks of grease on the fan cause aerodynamic imbalance and vibration on the ventilation system. Grease covered fans are also fire accidents waiting to happen. Cooking flare ups may cause fire to lap, at and ignite the grease on the hood. The fan will then suck the fire up through the grease covered ducts and up the roof. It behooves on restaurant owners to include degreasing and cleaning of their restaurant exhaust fan system as part of their regular maintenance procedures and customer service program.

Paint Booth Exhaust Fans Design Selection

Posted on November 5th, 2007 in Industrial by fan

Paint booth may be used for commercial purposes or as a hobby. Whatever is the main reason for owning and using a paint booth will still require it to have a good environment to work on. Paint contains chemicals and other hazardous toxic and explosive substances. Therefore proper ventilation within the paint booth area is needed to ensure safe and healthy environment.

The need for a paint booth exhaust fan is always required in order to impose safer ambience while working on a paint booth. Concern about paint booth exhaust fan selection is regarded in relation to the amount of air drawn into the booth that can significantly cause contamination of the paint with dusts and dirt. With the airflow system from a paint booth exhaust fan, the venue where the paint booth will be use, the spray equipment type and the environment condition are all determinant factors on the type of paint booth exhaust fan you will need to install.

Paint booth exhaust fan can be an effective means of exhausting paint fumes out of the booth to create a healthier environment. Several considerations can serve as guidelines prior to paint booth exhaust fan purchase. Selection for the right kind of paint booth exhaust fan will depend on the paint booth size, the airflow requirements, the static pressure involved, the direction of the draft and the diameter and length of the duct.
.
The booth size of the paint booth exhaust fan will be equal to the size of the paint booth where it will be installed. The bigger the paint booth size, the bigger paint booth exhaust fan you will need. Make sure that the paint booth size will be wide enough to make you feel comfortable of doing the paint job. When unsure of the size proportion, it would be smart to use a mock design in the form of cardboards to determine a comfortable space size.

The direction of the draft of the paint booth exhaust fan can be either cross-draft or down-draft airflow. With the cross-draft booth, air is pulled through inlet filters that are located in booth doors which are brought into the exhaust filter that are located opposite the inlet filters. This kind of draft can cause dust and dirt to easily settle into the paint because the air that enters the booth will pass cross the area being painted. A down-draft booth reduces dust and dirt contamination due to the lower air volumes that are required during ventilation. The rule of thumb regarding the airflow required for installing a paint booth exhaust fan should be 100 FPM face velocity for cross-draft booth and 50 FPM downward velocity for down-draft booths.

The type of paint booth exhaust fan should be sturdy and made up of heavy duty materials. It is important to choose an explosion proof kind of exhaust system because of the chemical hazards that are released to the air from the paint. Flammable vapors may linger in the air and the paint booth exhaust fan needs to work efficiently in clearing the air from these substances. It is important therefore to choose an efficient paint booth exhaust fan capable for the immediate rid of explosive fumes that are safety hazards.

Heavy-duty Ventilation Through Industrial Exhaust Fans

Posted on October 31st, 2007 in Industrial by fan

Commercial establishments like malls and museums are frequent with visitors everyday. These establishments offer a variety of shops to explore and visit while basking in the cool airconditioning in full blast. Production plants and warehouses on the other hand consider airconditioning a costly investment and expensive to maintain. For these powerhouses, industrial exhaust fans are installed to prevent air stagnation and discomfort.

Industrial exhaust fans are best used in high volume and high pressure environment like factories. Damp and stagnant air can damage the equipment used in manufacturing products. This can also ruin the raw materials needed for production. It can also cause discomfort to the employees and can further cause and aggravate health problems. As you may have noticed, manufacturing plants have high ceilings with huge industrial exhaust fans overhead mounted on the ceilings or roofs. Gymnasiums in schools and universities use industrial exhaust fans to ventilate the area while protecting the material of the floor from accumulating moisture. Imagine a jam-packed basketball game in the gym with no industrial exhaust fans. Body heat from mingling with one another can cause heatstroke within the gym premises and at the same time, body odor suffocation for those present.

Underground parking spaces make use of industrial exhaust fans for health reasons. The smoke from cars and vehicles contain carbon monoxide that can be deadly when in concentrated form. Industrial exhaust fans provide heavy-duty ventilation in underground parking spaces to clean the air from carbon monoxide and other lethal gasses.

Industrial exhaust fans come in different models based on mounting locations. Examples of industrial exhaust fans are roof and ceiling exhaust fans and ventilators, free-standing industrial exhaust fans and wall and panel industrial exhaust fans. Among the models, the roof and ceiling industrial exhaust fans are typically used. Since warm air is lighter than cold air, the use of these industrial exhaust fan models speed up the flow of warm air going outside the building and replace it with cold air from the outside. For free-standing industrial exhaust fans, these are positioned anywhere in the premises to provide standard ventilation. This type of exhaust fan can be moved around where ventilation is most needed.

When the air around us gets uncomfortable, we find means and ways to ventilate ourselves for comfort and protection. The same purpose applies to the installation of industrial exhaust fans in commercial and industrial environments. It is to provide comfort to the occupants while protecting the surroundings from moisture damage and bacterial growth.
