How is the Fan Filter Unit Better than the Fan Clean System?
FFU has several advantages over the fan clean system, some of them are explained below:
Air Flow Creation
Its laminar flow enables it to fulfill the requirements of a 100-grade clean room.
On the other hand, a fan clean system is not able to create enough airflow. Also, it has a larger gap between the air filter and fan, so it can’t tolerate 100 degrees.
Offers More than One Fan for Clean Room
The fan clean system has a major drawback, which is the presence of a single fan in it. If any problem occurs with this single fan, the whole equipment stops working.
But in Fan Filter Unit it is more convenient to continue operating even if one of the fans stops working.
Longer Life Span
In comparison to a fan clean system, the high-efficiency filter of the Fan Filter Unit has a longer service life.
The main reason behind this is the requirement of a pressure block for installing the filter in a fan clean system.
Also, the fan clean system has higher chances of an unsteady airflow, which can result in its non-operational state.
The Fan Filter Unit has better sealing, which refers to fewer leakage problems. Many individuals are concerned about leakage in a fan clean system.
Leakage can make maintenance difficult, so make sure that you are purchasing a leak-free system.
Airtight Clean Room HEPA Fan Filter Unit
Always keep low noise production in your mind when you are deciding to purchase or not purchase a system.
A fan clean system has higher power consumption along with greater noise production. This is one of the significant reasons why a large number of individuals will choose it for a variety of applications.
How is a Dry Coil Fan Filter Unit Better than Other Methods?
A dry coil Fan Filter Unit has multiple benefits over other systems such as:
- Improved flexibility and ability to cover a broader area define the system. A clean air-conditioning system has no doubts about its adaptability.
Because of its high degree of adaptability, you may make this one fit your requirements exactly.
- The ceiling and the negative pressure of the FFU required a sturdy and durable seal which can be achieved with the dry coil as compared to the wet coil system. In other words, the clean room is cleaner than the regular room.
- The dry coil Fan Filter Unit has lesser chances of air resistance than the wet coil one. This implies that you could have a unit that is extremely energy efficient.
- It consumes less energy, therefore you can operate it for weeks without fearing high energy consumption.
- Other than all these things, it enables you to customize the various parameters to meet your own energy needs.

When changing the filter, and particularly when handling the filter, stay cautious. The same implies when unpacking and installing the system. Hand contact with the filter paper is strictly prohibited.
Visually check it in strong light prior to installation to ensure it is still in good shape. Occasionally, a broken filter can result during the careless transporting procedure. Also, if it is leaking, it cannot be used.
If you are replacing the filter, turn off the power supply first. To access the old filter, detach the cabinet cover that covers the high-efficiency filter. After removing the old filter, install a new high-efficiency filter in its place.
Ensure that the cabinet cover on your Fan Filter Unit is reinstalled in the same manner as it was previously.
After the new filter is installed, you should check for leaks using a dust particle counter.
You should also consider checking the frame for leaks. If there are leaks in any instance, apply sealing materials or seals to plug them.
Filter Replacement of Fan Filter Unit
When Should you Replace your Fan Filter Unit?
Under normal conditions, it is suitable to replace your filters after 3 to 7 years. However, more precisely, the best time for replacing your filters is when they no longer fall according to your requirements and needs.
This depends on the number of applications and for how much time you are using them.
For example, some units function at their full capacity while some function with partial capacity.
This time duration can be increased by installing prefilters, which will be helpful in reducing the workload on the main filters.
Filter Replacement of Fan Filter Unit
What is the Installation Procedure for your Fan Filter Unit?
You must approach the installation at a construction site in two sections. The high-efficiency filters must first be installed, followed by the Fan Filter Unit installation.
Before installing, properly clean the working area to remove the contaminants. Dust can readily build within the cooling system at times.
Therefore, regardless of where you can choose to install the filter, make certain that it is completely cleaned.
On this point, the clean room must be shut down. It’s because you may need to perform a test run of the system to ensure it is functioning properly.
After cleaning the surfaces, immediately install the high-efficiency filter. People who will install the filter must practice caution to avoid causing damage.

How to Troubleshoot your Fan Filter Unit?
The following are some of the problems that are likely to be encountered, as well as their solutions are explained below:
Insufficient Air Velocity
A power source that is perfectly compatible with your system is necessary including proper voltage, current, and speed.
If the power source is in good condition, you still can increase the speed of the system. This could be because demand has increased, necessitating the adjustment of the system’s performance as well.
Increased airflow from the fan impeller is expected as the speed percentage increases. In case the rate of airflow is extremely low even after repairing it multiple times, then replace it.
Extremely High Air Velocity
If the velocity of air is extremely high, it is suitable to decrease the speed ratio of the Fan Filter Unit.
This leads to a reduced air output volume released by the rotor installed in it.
A Non-Laminar or Impure Air Flow
This is a regular occurrence when huge impediments in the channels obstruct air passage upstream. The most probable solution is to remove these contents.
Verify whether another piece of airflow equipment is located in the same clean area, as it may impair the Fan Filter Unit’s normal airflow.
Always maintain the airflow frequency to a suitable level. In case it is very high, decrease the fan speed, and if it is very low, increase the fan speed.
Fan Filter Unit efficiently cleans the incoming air, only if it is properly maintained. Paying great attention to timely replacement of various parts is also essential for good working.
You can use multiple accessories to increase its effectiveness and life, also customization is available to design your unit according to your needs.
For greater life, it is always advisable to use a prefilter along with the other filters, this will reduce the main load by filtering some of the air.
Timely servicing of your product conducted by professional technicians is crucial for its maintenance and durability.
