While commercial exhaust fans will wear out over time, like any other type of kitchen equipment, taking care of them and properly maintaining them can significantly improve their lifespan – and of course will ensure they’re working at top capacity. Fire codes will indicate the absolute minimum that you must clean various parts of your exhaust system, though your kitchen may need maintenance more often. Here are some tips from Hoodmart to help you take good care of your equipment.
Don’t forget to cut your electrical supply
When you’re performing maintenance on your exhaust fan, make sure you turn off the electrical supply before you start. This means you must completely disconnect it. Don’t just power the fan off. Instead, unplug it completely. If that’s not possible, than cut the power to that section of your power by using your breaker box.
Some parts should always be clean
There is some cleaning that needs to be done monthly, some just once or twice a year, while other things should be cleaned daily. Your fan discharge and approaches to your ventilator are examples. They should always be clean and 100% free of obstruction. They should be checked nightly to ensure this is the case.
Check your bearings every two months
These days, most fan motors are permanently lubricated and don’t require maintenance. However, you’ll still want to take a look at the bearings once in a while. If they use grease fittings then you’ll want to lubricate them every three months or so – so perhaps you’ll want to do it once per season. Your bearings should be lubricated every two months. Remember that bearings are sealed and if you over grease them, you could damage. Don’t grease them until grease actually comes out of the seals. Even then, only add the amount they need.
Check your fasteners
Anytime you open up your fan for maintenance, make sure you check your fasteners before you restart your unit. It’s important that they’re nice and tight. If they’re not, then you could damage the unit and could even be causing a safety concern.
Keep an eye on your wheel
If your fan is doing nothing but moving clean air, then it won’t require must attention at all. However, most kitchens have plenty of oil and dust. These can eventually build up and cause imbalance. If your fan in an atmosphere that’s dirty or has corrosive products, then you should check it out once in a while, clean the wheel and inlet, and make sure it’s running safely.
