Components Of EC Ffu's

Installed on the ceiling of the cleanroom, it consists of a fan and a filter. In addition, sensors and elements for heating or cooling the air can be integrated into the Components Of EC Ffu's.
A large number of FFUs are often installed on the ceiling of cleanrooms. In this case, the fans must operate reliably and safely, as well as being highly energy-efficient and therefore durable.

----------------------------The air output is uniform and stable----------------------------

 

FFU has its own fan, and the air output is uniform and stable. The problem of air volume balance at each air outlet of the centralized air supply system is avoided. It is especially beneficial for vertical unidirectional clean rooms.

 

----------------------------FFU structure----------------------------

Fan filter units (Fan Filter Units) are referred to as FFU, which is a self-powered terminal air supply device with filtering function. From the structural point of view, FFU can be divided into two types: one is integral type and the other is split type. Integral Fans and equipment for filter fan units in clean rooms refers to the integral design of its box and High-efficiency Particulate Air Filter. The advantages of integral FFU include increasing the airtightness of FFU, effectively preventing leakage; it is conducive to reducing noise; it is conducive to reducing vibration.
Split FFU refers to the split design of its box and high-efficiency filter. Split FFU has the advantages of making filter replacement convenient; reducing labor intensity during installation.

 

----------------------------FFU components----------------------------

Clean Room Ceilings/FFU - Fan filter unit is composed of outer shell, metal protective net, pre-filter, motor, impeller, air flow balancing device, high-efficiency non-partition filter, air duct connection components, and control unit.
Functions of each component
1. Outer shell
The main materials of the outer shell are cold plate baking paint, stainless steel, aluminum-zinc plate, etc. There are different choices for different use environments. There are two shapes. One is a sloped top, which mainly plays a role of guiding flow, which is conducive to the flow and uniform distribution of the intake airflow; the other is a rectangular parallelepiped, which is beautiful and can make the air entering the shell have the maximum positive pressure to the filter surface.

2. Metal protective net
Most metal protective nets are anti-static, which mainly plays a role in protecting the safety of maintenance personnel.
3. Pre-filter
The pre-filter is mainly to prevent the damage to the high-efficiency filter caused by debris generated by construction, maintenance or other situations. Its material is generally washable polyurethane fiber.
4. Motor
The motors used in ffu air purifier now include DC motors and AC motors, and they have their own advantages. DC motors are large in size, high in investment, easy to control, and have high energy consumption. AC motors are small in size, low in investment, require corresponding technology for control, and have low energy consumption.

5. Impeller
There are two forms of impellers, forward and backward. Forward inclination is conducive to increasing the sagittal flow of airflow organization and enhancing the ability to remove dust. Backward inclination is conducive to reducing energy consumption and noise.

6. Airflow balancing device
With the wide Components Of EC Ffu's in various fields, most manufacturers choose to install airflow balancing devices to adjust the outlet airflow of FFU and improve the airflow distribution in the clean area. At present, it is divided into three types: one is the orifice plate, which mainly adjusts the airflow out of Energy Efficient FFU by the density distribution of holes on the plate. One is the grid, which mainly adjusts the outlet airflow of FFU by the density of the grid. The other is the dynamic curve, which mainly induces the flow of airflow by the shape of the curve, and also adjusts the airflow by the density distribution of holes on the curve.
7. Duct connection components
In the case of lower cleanliness level (≤1000 federal standard 209E), there is no static pressure box on the top of the ceiling. The FFU with duct connection components makes the connection between the duct and FFU very convenient.
8. High-efficiency non-partition filter
High-efficiency filters are mainly used to capture 0.1-0.5um particle dust and various suspended matter. There are mainly partitions and no partitions. The high-efficiency non-partition filter is used in FFU.
9. Control unit
The control of FFU-HEPA - Recirculating Fan Filter Unit can be roughly divided into multi-speed control, stepless control, continuous adjustment, calculation and control, etc. It can also realize single-unit control, multi-unit control, partition control, fault alarm, historical record and other functions.
