Extractor Fans

Extractor fans are an essential component of your kitchen. They draw out any air and moisture that you do not want, removing all fumes and odours from the room. Fans can become dirty and require cleaning. This is just as important in commercial kitchens as well as domestic ones, as the fans are bigger. They also contain filters that require regular cleaning. These can cost a lot of money to replace, so ensuring they remain in good condition is vital.

There are two types of fans: ducted and recirculating. Ducted fans are the most common and are installed above the cooker hob. They are connected to an external vent that takes the air outside. Recirculating fans are not as effective but they do not require an external vent. Instead, they have a charcoal filter that absorbs smells and odours.

How Often Should You Clean Your Extractor Fan?

 Cleaning your extractor fans ensures that microscopic particles of grease do not settle on any kitchen surfaces. They can easily become clogged and blocked with grease, which can cause the fan to become louder and less efficient. It can even lead to bad smells and sometimes fires.

Therefore, it is essential to regularly clean your commercial extractor fans. We recommend you clean them at least once every two-three months. If you do not have the time or capabilities to clean your fan, hire a professional commercial cleaning service. They will be trained to tackle the filters, blades, and body of your fan.

How To Clean Extractor Fan Filters

Your extractor fan filters are fine mesh grates that prevent grease from reaching the extraction vent. They can become clogged easily and cause the fan to work inefficiently.

To clean your extractor fan filters, you will need:

  • Warm water
  • Dishwasher soap
  • A cloth
  • Bicarbonate soda
  • A non-abrasive brush

Your first step is to carefully remove the filters from the hood. Add the soap and some bicarbonate soda to the water, and mix the solution together. Carefully place the filters into the water (remember it should be very hot) and ensure they are completely submerged. Allow them to soak for roughly 10 minutes, before scrubbing them with the brush. For the stains that are more persistent, add more dishwasher soap directly to the brush.

Once you have removed all grease and grime, rinse the filters and gently dry them with a soft cloth. Place the filters back into position.

Some fans may have filters that are paper or carbon. Depending on the manufacturer’s guide, these may need replacing over-cleaning.

How To Clean Extractor Fan Body

 You cannot just clean the fan filters and expect it to work. It’s important that you tackle the entire body of the fan. If grease has built up all over your extractor fan’s body, it will be less effective.

Before you start cleaning, you should ensure you haven’t just used the hob, as it may still be hot. Unplug your fan from the mains before you start. If you can, remove the outer cover and let it soak in a solution of warm water and washing-up liquid. If you can’t remove the hood, wipe it carefully with the washing-up liquid solution and a damp cloth.

Rinse and dry thoroughly with a kitchen towel to ensure it is dry before the next use. 

How To Clean Extractor Fan Blades

 It is also important to clean your extractor fan blades. Cleaning the fan blades will help improve ventilation and ensure the fan operates more effectively. If you can, remove the fan blades. If not, you have to reach them comfortably.

You need to take a cloth, and using warm water, dishwasher soap, and white vinegar, gently wipe the blade. Repeat this process until the blades are free from all grease and dirt. However, make sure you do not get the blades too wet and dry them completely before attaching to power.

 What Should You Do If Your Extractor Fan Is Not Working?

 Your extractor fan could have stopped working for a number of different reasons. The motor could be faulty, a fuse could have blown, or your filters could be blocked.

If your motor is faulty, it is likely it will need replacing. The motor could have stopped working because of an inadequate electric supply. It could be damaged because of some sort of blockage preventing the fans from spinning, or it could be too old. To replace the motor, you need to switch off the power supply and remove the cover to access the internal wiring. Carefully remove the fasteners that keep the motor in place, and insert the new motor. Make sure it is securely in place before switching the power back on.

The fuse will blow because something has gone wrong. This is designed to protect your extractor fan, and many new models will come with their own electronic control panel. Fuses are easy to replace, but it is important to know why it blew in the first place. Otherwise, you risk a repeat occurrence.

A blocked filter is a sign your fan needs cleaning. Once you’ve followed the instructions above, your filter should be good as new, and the fan should work again. However, if you notice signs of damage, your filter will need replacing.

To Conclude:

It is important to keep an eye on your extractor fan and ensure it works efficiently. Don’t let grease and grime build up, otherwise, you could cause more problems, which will cost you more money. May sure you are aware of all commercial kitchen regulations and choose the right extractor fan for your needs. Ensuring your extractor fan is working and clean is key to keeping a good working kitchen.
