Now let us take a look at the 3 most common types of commercial vent hoods
Restaurant vent hoods with a duct system – with a ducted system the air will be vented to the outside of the building. The benefit of the duct system is that it will reduce some of the maintenance as you don’t have to change air filters as often when compared to a ductless system. However, it is a more expensive system to install and run because of the make-up air requirements, the duct installation, space requirements and it will increase your cooling and heating costs. These types of units are best installed over equipment that do not produce smoke or grease such as dishwashers, pasta cookers, kettles, steamers and other appliances that have combustible by-products, steam and heat.
Ductless restaurant vent hood – the way the ductless unit works is it will pass the air through a filter that has a material such as charcoal that will remove any smoke or odors from the air and then it recirculates the air though the kitchen. While this type of unit will recirculate the moisture and heat in the kitchen it is a lot cheaper to install and operate. You will typically find the ductless vent system over any appliance that produces smoke or grease such as pizza ovens, smokers, ranges, ovens, griddles, boilers and fryers.
The different styles of hood systems
The most common type is the canopy hoods, which is normally installed above any cooking equipment that is against a wall. Then there are Island Hoods and proximity hoods or back shelf hoods that are installed a lot closer to the cooking equipment, especially for lighter duty equipment and low ceiling establishments.
Common restaurant hood repair problems
The kitchen has smoke – this could indicate that your filters are clogged or that your hood system is not able to keep up with the increase demands of your kitchen.
There is smoke around the vent hood – This could mean that either the motor needs to be replaced or repaired, because there is a problem with the exhaust fan.
Problems with installation – most problems that are associated with vent hoods are because either you have the wrong size unit or it was not installed properly. There are several issues that could come about if your hood is not ducted properly, if it’s mounted at the wrong height, if it’s too small for your kitchen or if the wrong components were matched up.
