Benefits of Preventive Maintenance

Preventive maintenance doesn’t have to take a lot of time. In just a few minutes, with little effort, you can help keep your system at peak performance. You’ll have peace of mind and save time and money by not having to deal with last minute emergencies.
A main benefit of preventive maintenance is extending the life of your equipment and its components. Routine check-ups help you avoid costly component change outs and can keep your exhaust fan from suffering an early burnout.

With proper maintenance your fan will be more energy efficient. This will save you money on operating costs. In fact, routine preventive maintenance of rooftop ventilation systems has been shown to result in energy savings of as much as 11%.


1.  Inspect and Adjust Fan Belts:

Routine visual inspection and adjustment of your commercial kitchen exhaust fan belt will ensure that Fan belts don’t last forever so it’s also very important to look for any signs of deterioration and replace any cracked or brittle belts. If you notice a fan belt is riding low in the pulley during your inspection, you’ll probably need to change it.

2. Inspect Your Electrical Wiring and Cords:

Make sure that there is always plenty of extra slack in the electrical wiring to allow for the fan to be tilted back to the open position. Inspect the wiring and cords for any signs of deterioration or fraying. Confirm that there are no kinks in the cords and that all electrical connections are secure. Electrical cords and wiring should not be exposed to any hot surfaces, grease, or chemicals.

3. Check That the Fan Blades Are Balanced :

When commercial kitchen exhaust fan blades are not well balanced, it can cause excess vibration. When this happens, it can cause the entire rooftop unit to shake, which can cause screws, bolts, and other parts to loosen. This reduces the fan’s efficiency and compromises the security of its attachment to the rooftop.

Routinely check your fan for any excess vibrations. If you start to notice any, make sure that the fan blades are completely clean on both sides. Check for any buildup and remove. Even a tiny bit of grease in the wrong place can upset the balance and cause problems. You should also routinely check the fan for any damage to the blade assembly, which can also cause an unbalance.

We provice Preventive Maintenance Tips For Commercial Exhaust Fans :

In order to keep your commercial kitchen exhaust fan in tip-top shape, you must keep the fan bearings, fan shaft and motor well lubricated.

Lubricate the motors, the fan and damper bearings, the valve stems, and the fan and damper linkages. This will greatly extend the life of the components as well as the fan.
Preventive maintenance is an important part of keeping your business up and running. Following these 10 tips can help you improve the performance and safety of your commercial kitchen exhaust fan, extend the life of your restaurant ventilation system, and reduce the frequency of expensive repairs to your equipment.
