We all know that completely functional exhaust and extractor fans are very critical in any commercial kitchen. Without having installed a completely functioning exhaust fan in your kitchen, you will have to close your business down.

Commercial Kitchen
Exhaust Fan Motor
Replacement

2. Introduction
Exhaust fans are very important and critical to
maintaining the air quality in the indoor
environment by eliminating any particles & fumes of
smoke, steam, as well as extracting oil and grease
fibers from the kitchen. Any sort of grease that has
built up inside the fans and motors of kitchen
exhaust fans can ultimately damage them.

3. If the motor of your commercial kitchen
exhaust fan begins to make an unusual
noise, it may be due to the fact that the
motor is struggling to keep the fan running.
When it gets to this stage, it is likely to be
only a matter of time before the motor
burns out completely. In this case, replacing
the motor is the best option.

4. Basic Types of
Exhaust Fan
Motors
Most of the small exhaust fans use this kind of exhaust motor, which is
known as the standard motor, this is basically a single-phase motor.
These motors basically work on the principles of AC, and in each cycle,
they achieve an irregular maximum and minimum power. These are
considered as strong and durable as well as sturdy.

These kinds of motors are called split-phase motors and they are
basically used in huge industrial exhaust fans. These kinds of motors
usually have both start and run windings that get energized when we
start them. They are supposed to function better when put on the
medium current input. Due to their utilization in large and unwieldy
industrial equipment, these motors go through a considerable amount of
technical stress.
Exactly like its name, capacitor-start motors possess a built-in capacitor
with series windings. They produce twice the torque if compared to other
motors, with much less current input. Therefore, they are not only
considered powerful but also they are very energy efficient. Due to their
high-power generating capacity, they are used in large industrial
ventilation machinery.

5. Commercial kitchen exhaust fans usually
have single-phase induction motors, these
motors are also used in ceiling fans. They
are designed in such a way that they
perform the functions that they need to
serve at first. Most of the small exhaust fans
use this standard motor. Single-phase
induction motors usually consume
minimum power and thus, they are known
as fractional kilowatt motors as well. A
single-phase induction motor involves only
one power phase for its proper functioning.
So, it converts the electrical energy from the
power input into mechanical energy in less
time.

6. Rules &
Regulations for
Installation
Measurements
Safety
Make sure all of your measurements are accurate
because the next step of exhaust installation is
about having a proper cut out of your roof
opening where you will have to install your roof
curb.
If working with some professional installer, all you
have to do is to make sure that every kind of
electrical wiring and connections are being done
in order to abide by the local ordinances, building
codes, the National Electric Code, and NFPA 70.

7. Rules &
Regulations for
Installation
Site Preparation
You may have to provide enough clearance
around commercial kitchen’s exhaust fan
installation area.
You may have to ensure that you have a
grease drain that is piped to an approved
grease containment structure.
You must always maintain distance from any
combustible material.
Your exhaust fan should always be installed on
a manufactured or factory-built roof curb.
As discussed, and stated you must always
disconnect power supply before you install a
rooftop ventilator.
