Upblast Exhaust Fan - The Lungs of Your Kitchen

Upblast Exhaust Fan - The Lungs of Your Kitchen

Often described as the “lungs of your kitchen,” an upblast exhaust fan works to keep your restaurant’s interior clean by extracting smoke, grease particulates, cooking odors and other contaminants from the air. By directing them outside, these fans help to prevent the buildup of grease on roof structures or within ductwork, which can lead to a number of issues, including structural damage, duct fires and poor indoor air quality.

If you’re considering installing an upblast exhaust fan, it’s important to decide whether you will be mounting your unit on the roof or on a wall. You’ll also want to think about what kind of commercial kitchen it will be connected to — whether it’s a Type 1 or 2 hood that exhausts primarily heat and moisture, for example, you will still need an upblast fan to exhaust the contaminants away from the kitchen.

One of the most noticeable differences between upblast and downblast exhaust fans is the way their motors are housed. Upblast exhaust fans use a sealed compartment to protect the motor from things like heat, moisture and grease that will be pulled through the fan during operation. Downblast fans, on the other hand, do not offer this protection and can be susceptible to the same kinds of contaminants that will eventually be exhausted through your ductwork.

Upblast fans can be equipped with dampers to control the amount of incoming air based on your ventilation requirements. This feature helps to maintain a consistent airflow in the space and can reduce noise levels.

You can also find upblast fans with optional UL fire and smoke controls for emergency heat and smoke ventilation during a kitchen fire or other emergency. These units can help save lives by giving people time to escape from the building or reach exit doors safely, and they also reduce the amount of smoke that will contaminate the surrounding area.

In addition to the aforementioned features, you’ll also find upblast exhaust fans with various speed settings and CFM capacities for optimal performance and flexibility in your commercial kitchen. You can also use our CFM Select tool to determine the best fan based on your performance needs.

Both direct drive and belt drive upblast fans are available for purchase, and each provides its own set of advantages. The former utilizes a motor directly connected to the fan, resulting in more efficient and friction-minimized operation. This is a great option for restaurants that prioritize ease of maintenance and cleaning. The latter uses a pulley and belt system to control the motor, which can require more regular upkeep and maintenance.

You’ll also have the choice between single phase and three phase motors for your upblast exhaust fan — a consideration that will depend on your power supply. Regardless of your preferred model, you’ll be able to find an upblast exhaust fan that’s built with high-quality materials and designed for use in restaurant kitchens, warehouses and other industrial spaces. For maximum durability, choose a fan with stainless steel construction and a corrosion-resistant aluminum frame.
