Fan Filter Unit

1. Characteristic and use of the production

The Fan Filter Unit (FFU) is very universal purification equipment, normally installing on the every kind of frame, and it can form a highly clean environment for working. It has good effects on improving the clean-room’s condition, the quality of the production and the proportion of the finished product. The Workstation can widely use in every kinds of industry department and science lab, such as electron, national defense, exact instrument, pharmacy, agriculture and biology.

3. The structure’s characteristic and element

1. The structure’s characteristic

As the sketch map, the Flow Workstation makes up of cabinet, centrifugal fan, HEPA filter and operational on-off. The cabinet material use cold board plastic coated. The clean cells use the wind system that can change wind power. Through this process of changing, the average wind speed in the clean working area will keep in a rated range (0.3~0.45m/s). This can prolong the using time of air filter.

2. The element of working

The airs go through the pre filter, then into the pressure cabin by centrifugal fan, and go through the hepa filter at last. At this time, the clean air could come out and flow to the working area. The pressure in the working area is not same, so this can prevent the dust from outside. In order to enlarge the area of purification, we’d better use a dispersing component at air exit.

4. Adjust installation

1. You’d better put this production in the highly rate clean environment, at least 100 thousand rate.

2. The place you install it, should be away from the dust and the hypocenter.

3. As the map, the FFU should be installed from outside purification area, and be rooted by angle iron.

4. If you change the pre filter and high filter, you should do it according to this step: 1> the pre filter just need carry up it, then changes a new one.2> the hepa filter, you need open the cover board on the back, and then change it.

5. The operation of using

1. In order to ensure the purification in clean area, open the power for 15 minutes before using.

2. If you don’t use for a long time, please pull out the power pin. And before you stop using, you need clean it with the cleaner and some other tools that can’t produce fiber. If you use it again, do this in the same way.

3. Do not have boil action in the purification area.

4. According to your need, ensure the times of change the air.

5. According to your need, adjust the fan’s rate.

6. Do not put the sundries outside the pre-filter, in that case, it will reduce the wind and the ability of purification.

6. The analyzing and removing to troubles

Troubles	Reason	Solving
The average wind speed is under or up the Wind Rating	The fan ‘s pressure is too low or too high	Adjust the switch of the fan’s speed
The wind speed is slow although the switch has changed into the highest.	1. Too much dust in Pre-filter 2. The HEPA filter is disabled	1. Clean or change a new pre-filter 2. Change a new HEPA filter
The fan isn’t running	Power line can’t use	Examine the power line

7. Maintaining of FFU

1. According to the clean rate in environment, you need to change the air filter timely. (usually 1~6 months)

2. When you change the pre-filter or HEPA filter, please stop the FFU first.

3. Remarks in changing HEPA filter:

1) Please be carful in changing the HEPA filter, in order to make sure the filter is whole.

2) When changing a new HEPA filter, open the cover board first, takes off the old one and then fit on the new HEPA filter.

8. Transporting and storing

This purification cell could be transported by normal vehicle, but in this process, make sure it’s water-proof.

This purification cell should be stored in the house that temperature is between -10℃~ +40℃;the relative humidity should be lower than 80% and without acid and alkali corrosive gas.

The storing time limit can exceed 180 days in the state of having been packed.

9. Examine

1. When you open the box, please be careful for fear damage the purification cell.

2. When you open the box, please check it whether it is your order production. If you have any question, please contact me in a week.

3. Please pay attention to following circumstances:

1) Do not operate the power switch in a short time again and again.

2) This production can not have guard against riot ability, so do not operate in the circumstance of flammability and easy-blast.

3) Please do not touch the element in the production. If you really need, please cut off the power first.

4) Strictly prohibit refit the machine, or it will result in getting an electric shock or fire.

5) When you need to examine the machine, please cut off power.

6) Do not put heavy thing on the power line, or else it will be broken to get an electric shock or fire.

7) When you change a new fuse, please make sure its capacitance is in the rated lost.

8) If you do not use for a long time, please pull out the BNC connector plugs.

9) If there is some special things happened, please stops using and connected our company.

10) Please connect the power line with a natural BNC connector jack.
