Why does EFU need to be customized? What is the difference between standard EFU and custom EFU?
When purchasing EFU, many customers will first ask:
'Are there any standard models that can be used directly?'
For some equipment with relatively conventional installation space and technical parameters, standard EFU can indeed meet the needs.
But for EFUs used inside devices, the situation is often more complicated.
Because EFU is not installed alone in a standardized clean space, but needs to cooperate with specific equipment.
Different devices:
The installation space is different
Air volume requirements are different
Wind speed requirements are different
Filtering requirements vary
Different control methods
Therefore, some projects need to be customized according to the actual conditions of the equipment.
3. What is the difference between standard EFU and customized EFU?
Simply put:
Standard EFU
The manufacturer has determined:
Main parameters such as size, fan, motor, filter, control method, etc.
Customers choose the appropriate model according to their own needs.
Custom EFU
According to the actual requirements of customer equipment, for:
Size, structure, air volume, wind speed, filter, motor, fan, control system, etc.
Perform a rematch.
It can be simply understood as:
The standard EFU is 'select the product', and the customized EFU is 'design the product according to the equipment'.
4. Under what circumstances is it necessary to customize EFU?
Not all items require customization.
The following situations are more suitable to consider customization.
1. Special installation space
For example, there are only:
70mm
Installation height of left and right.
Ordinary EFU cannot be installed, so the structure needs to be reconsidered.
2. Dimensions are not standard specifications
For example, customer requirements:
special length
special width
Highly special
Or the mounting hole position is special.
In this case, the standard product may not be directly installed.
3. There are special requirements for air volume
Customers may have identified:
A certain target air volume is required.
The air volume of the standard model cannot be matched.
At this point you need to do it again:
Fan + motor + filter
match.
4. There are special requirements for wind speed
For example, equipment process requirements:
A certain area maintains a specific wind speed.
At this time, it is necessary to:
Air supply area + air volume + wind speed
Make a match.
5. Filters have special requirements
For example, the customer specifies:
HEPA
or:
ULPA
Filter size, filtration rating, or mounting method may also be specified.
6. Special control method
For example, the EFU needs to be linked with the equipment control system.
May require:
speed regulation
Start/stop control
status feedback
communication
and other functions.
5. What content can EFU customize?
EFU customization is not just about changing a shell size.
This can usually be done from the following aspects.
1. Overall dimensions
It can be adjusted according to the equipment installation space:
length
width
high
2. Installation structure
Can be adjusted according to the device installation method:
Installation hole position
Fixed method
Flange structure
Interface location
wait.
3. Air volume
Determine the target air volume according to the needs of the equipment, and match the corresponding fans and motors.
4. Wind speed
Determine the target wind speed based on the actual air supply area inside the equipment and process requirements.
5. Filter
You can choose according to your cleaning requirements:
HEPA
ULPA
and corresponding dimensions and structures.
6. Motor
according to:
Air volume
wind pressure
Installation space
Operation mode
Choose the right motor.
7. Fan
The fan needs to be used with:
motor
filter
system resistance
Make a match.
8. Control system
Can be configured according to device requirements:
independent control
Speed control
Device linkage
Communication control
etc.
6. Why can’t we just change the shell size of the EFU?
This is an easily overlooked issue in custom EFU.
For example, the customer said:
'The height of my equipment is only 80mm. Just press the ordinary EFU to 80mm.'
Not necessarily.
Because EFU also needs to be installed internally:
motor
fan
filter
And it needs to be reasonable:
Air flow channel.
If you just make the shell thinner, it may cause:
therefore:
EFU customization should be system design, rather than simply modifying the sheet metal size.
7. Which components are the most important to match in EFU customization?
EFU can be regarded as a complete system:
Equipment requirements ↓ Installation space ↓ Target air volume/wind speed ↓ Filter ↓ System resistance ↓ Fan ↓ Motor ↓ Control system ↓ EFU complete machine
Changes in any one link may affect other components.
For example:
Filter resistance increases
↓
Fans require more pressure
↓
The motor operating point changes
↓
Actual air volume may vary
Therefore, customizing EFU requires comprehensive consideration, rather than just looking at a certain parameter.
8. Why does ultra-thin EFU need to be customized?
Ultra-thin EFU has stricter requirements on internal space.
For example, a product with a height of about 70mm needs to be arranged in a very limited space:
motor
fan
filter
air flow channel
control parts
Therefore, ultra-thin EFU usually needs to be considered starting from the overall structure.
For applications where the internal installation space of some equipment is limited, Aili Industrial can provide an ultra-thin EFU solution with a height of about 70mm.
Actual product height and performance parameters need to be determined based on specific equipment requirements.
9. When is standard EFU more appropriate?
If your device meets the following conditions:
The installation size is relatively conventional
Air volume requirements are relatively clear
Wind speed requirements are conventional
Filter specifications match
The control method is relatively simple
Standard products can be installed directly
Then standard EFU is usually more straightforward.
In this case, there is no need to customize for the sake of customization.
10. When is it more appropriate to customize EFU?
If the device exists:
special size
Limited installation space
Special air volume
Special wind speed
Special filtering requirements
Special control method
or:
Equipment linkage requirements
Then a customized EFU would be more appropriate.
Especially when the internal space of the equipment is relatively compact, matching the EFU structure in advance can reduce the problems of later installation and adjustment.
11. Why do semiconductor equipment often need customized EFU?
Semiconductor devices often contain multiple complex modules.
EFU is required with:
Process module
Mechanical structure
Electrical components
and other device components
Make spatial coordination.
Therefore it is possible to simultaneously propose:
height limit
Wind speed requirements
Airflow uniformity requirements
Cleanliness requirements
control requirements
and other conditions.
Projects like this usually don't allow you to select products in just one standard size.
12. Can EFU be customized for photovoltaic and lithium battery equipment?
Can.
For example, lithium battery equipment may focus on:
Air volume
wind speed
device space
Photovoltaic equipment may need to consider comprehensively:
Cleanliness requirements
Installation structure
air supply
and other factors.
Specific parameters still need to be determined based on the equipment process.
13. Can the EFU be customized for the placement machine?
Can.
The internal space of electronic manufacturing equipment such as placement machines is usually compact.
EFU may be required based on:
Installation height
Installation location
Air supply area
wind speed
Filtering requirements
Make a match.
If standard products cannot meet the internal space of the equipment, custom structures can be considered.
14. Why can Aili Industry do EFU customization?
The really difficult part of EFU customization is not just sheet metal processing.
If you just modify the shell size, it's relatively easy.
What really needs to match is:
motor
fan
filter
airflow structure
control system
Overall structure
relationship between.
Aili Industry has established a production system covering these links:
Self-produced motor
Self-produced fans
self-produced filter
Self-produced software and hardware for automatic control system
Self-produced sheet metal
Whole machine assembly
Therefore, in the EFU customization project, collaborative design can be carried out from core components to the entire machine structure.
15. Where can I start EFU customization of Aili Industrial?
Customers do not necessarily need to provide a complete EFU design solution from the beginning.
This can usually be provided first:
Equipment installation space
For example:
Length×width×height
Air volume requirements
If it has been determined, it can be provided directly.
Wind speed requirements
If the equipment has specific requirements, target values can be provided.
Filtering requirements
For example:
HEPA/ULPA
Power requirements
For example:
AC/DC
and the corresponding voltage.
control requirements
For example:
Independent speed regulation/equipment linkage/communication control
Equipment drawings
If there are equipment 3D drawings, installation location drawings or photos, they can also be used as design input.
16. Basic process of EFU customization
It can be simply divided into:
Requirements confirmation
↓
Device space confirmation
↓
Confirmation of air volume, wind speed and filtration requirements
↓
structural design
↓
Motor and fan matching
↓
filter match
↓
Control system design
↓
Prototype or plan confirmation
↓
Whole machine production
↓
test
↓
deliver
This allows the EFU to truly correspond to device requirements.
17. Is customized EFU necessarily more expensive than standard products?
This cannot be simply judged.
Cost is usually related to:
Product size
fan
motor
filter
control system
Material
quantity
as well as:
degree of customization
related.
If it is just some size adjustments, and the complex structure and control system are customized, the cost difference will be relatively large.
Therefore, actual projects need to be evaluated based on specific plans.
18. What should you ask when choosing an EFU manufacturer?
If you are going to find a manufacturer to customize the EFU, you can focus on asking:
Can it be designed according to the size of the equipment?
Can the air volume be adjusted?
Can the wind speed be adjusted?
Can it match HEPA or ULPA?
Can we make ultra-thin structures?
What are the configurations of the motor and fan?
Can the control system be linked with the equipment?
Can you provide a prototype for testing?
These questions go beyond simply asking:
'Do you have EFU?'
It is more helpful to judge whether the manufacturer is truly suitable for your project.
