HEPA Fan Filter Unit Testing
What is a Clean Room HEPA Fan Filter Unit?
A Clean Room HEPA Fan Filter Unit is an advanced clean room filtration unit that helps in filtering particles of the desired size into the clean room environment.
This size depends on the type of filter installed in your FFU and your application requirement demands.
Using a pre-filter the air is first taken inside by the fan, and then the sub-micron particles are filtered by ULPA or HEPA filter to give purified and clean air supply.
A Clean Room HEPA Fan Filter Unit is better to use for providing localized clean air to the clean room environment than a traditional AHU (Air Handling Unit) because it saves energy and gives efficient results.
Another name for clean room HEPA filters is an integrated blower module and helps efficiently in controlling the contamination spread inside a clean room.
As compared to traditional AHU, FFU has higher energy efficiency and frequent usage in modern clean room designs.
When choosing your desired FFU consider the right size, best filter media options, and suitable airflow rates.

Which Precautionary Measure you Should Consider for your Clean Room HEPA Fan Filter Unit?
For using a Clean Room HEPA Fan Filter Unit, you must follow the given precautionary measures:
As soon as you receive the shipping, make sure there is no shipping damage through inspection.
If there is any shipping damage to the Clean Room HEPA Fan Filter Unit, go for a freight claim with the company that shipped your package. Also, evaluate the extent of damage and explain it clearly in the bill.
The HEPA filter media and the HEPA filter box shall not be touched with bare hands. It is protected by a metal screen that is painted and protects the downstream side in case of an accident.
Thus if you touch the screen, there can be damage to the filter. Only use the aluminum frame to carry or lift the system. Also, if the filter media is damaged, you would not be able to opt for a warranty.
It shall never be handled in such a way that it is placed on its filter.
Always place it on its side instead. Don’t use the blower assembly as a handle as it can break and therefore only approach the system from its sides whenever you need to lift or transport it.
Before you start the Clean Room HEPA Fan Filter Unit again see if there is any damage due to foreign objects. If it is slight, it can be tolerated but if the damage is significant, immediately report it.
Make sure there is an appropriate power supply before powering your unit. Also, the power supply shall be well insulated and stable.

How to Extend Clean Room HEPA Fan Filter Unit Life and Reduce Operational Cost?
As a clean room runs for 24 hours a day, all 7 days of the week, it is important to increase the life of your Clean Room HEPA Fan Filter Unit and reduce its operational cost.
Running such a well-designed system is costly but if it shuts down or its efficiency is decreased, the loss of productivity is much more than the money spent on the system in the first place.
If it is shut down, you have to shut down the clean room which leads to direct loss of time and money invested in all the reactions being carried out over there.
Restarting the Clean Room HEPA Fan Filter Unit might take some hours or even a few days depending upon the type of damage or error.
When the fan filter unit for clean room is not being used, slow down the fan filter speed. This helps to improve the life of the filters and the motor. Also, slow fan filter speed helps in reducing operational costs.
FFU Filter Cleaning
When is Clean Room HEPA Fan Filter Unit Replacement Required?
The Clean Room HEPA Fan Filter Unit replacement and maintenance play an important role in the overall efficiency of the system which directly affects the productivity of the clean room.
A HEPA or ULPA filter has a usual life span of 3-5 years but it can be extended to 7 years with good maintenance and appropriate use.
Some of the Clean Room HEPA Fan Filter Unit models may last more than the expected life span because they were not used enough.
It might be due to the application for which they are being used. The filter-load and the contaminant load in the clean room are also considerable factors.
For some applications and environments, the filter must be used to its full capacity, however, in some cases, only a fraction of its capacity is used and thus produces satisfactory results.
The use of prefilters, their cleaning, and timely replacement can also help you save on the cost of new filters. The prefilter takes most of the filtration load thus making it sustainable for the main filter.
However, the best time to change your HEPA and ULPA filters is when you realize that it no longer works as good as it used to before, and changing the filter would bring a considerable change in your productivity.
To check the performance of your filters, you must go for particle counting. It is the most reliable test in this regard.
This is to ensure that your clean room is in accordance with ISO or federal standards. If you are dealing with a class 10 clean room, it must fulfill all the criteria of this class.
For more precision, and quantitative analysis, calculate the static pressure and see if it is twice the value of initial resistance.
This is also a way to see if it is time to replace your filters. The pressure is measured in the supply air plenum before the HEPA filter and after the blower.
