High Efficiency Filter Outlet HEPA Box With Smooth Diffuser Plate For Pharmaceutical Cleanroom

The high-efficiency air outlet is an ideal terminal filtering device for the thousand-, ten-, and one-hundred-thousand-level purification air-conditioning systems, and can be widely used in clean air-conditioning systems in industries such as medicine, health, electronics, and chemical. The high-efficiency air outlet is used as a terminal filtering device for the transformation and construction of clean rooms of Class 1,000, Class 10,000, and Class 100,000, and is the key equipment to meet the requirements of cleanliness. The high-efficiency air outlet includes static pressure box, diffuser plate, high-efficiency filter, and the interface with the air pipe can be a top or side connection.

Features

1. The box body is welded with high quality cold rolled steel panel (electrostatic spraying) or stainless steel panel. Through special leakproof structure design and combined with special treatment of all welding lines, the possible leakage problem of the box body is avoided.

2. The fixation method of the diffuser panel is generally divided into side fixation and bottom fixation. Customers can choose according to their own requirements.

3. The filter stationary frame is made of the whole plate, which ensures the flatness of the filter fixed surface and effectively prevents air leakage.

4. Special filter press device can fix the filter well on the installation position, and it is easy to disassemble and install.

5. HEPABOX can be used for in-situ detection. Filter integrity test interface is reserved on the box, and PAO/DOP test can be conducted directly in the room.

6. HEPABOX can be used for in-situ inspection. The filter integrity test interface is reserved on the box, and PAO/DOP testing can be performed directly indoors.

7. Adjust valve and insulation layer can be installed according to user requirements.

In order to ensure the filtration efficiency of the filter and the cleaning effect of the cleaning system, the high efficiency filter installation must comply with the requirements of clean room construction and acceptance code or design drawing.

1. Preparation before installation in order to prevent hepa from being polluted, the air cleaning system must be installed after the unpacking inspection and installation. The air conditioner, hepa box, air duct and clean room must be cleaned.Before installation, check the flatness of the end face of the filter frame or edge mouth, and the allowable deviation of the flatness of the end face should be no more than 1mm each.

If the flatness of the end surface exceeds the allowable deviation, only the frame end surface of the filter installation is allowed to be modified or adjusted, and the outer frame of the filter itself is not allowed to be modified, otherwise the filter material or sealing part in the filter will be damaged, reducing the filtering effect.

2. Installation requirements when installing hepa filters, ensure that the direction of airflow is consistent with the arrow mark on the outer frame.High efficiency filters assembled with corrugated plates must be vertically mounted, not in reverse.The high efficiency filter and the frame of the assembly high efficiency filter are usually sealed by the jacking method and the pressing method.

Remarks:  

1. Side air outlet model only available with square port.

2. Dimensions above is suitable for mechanical-sealed and design with PAO testing port.

3. Tolerance of performance initial pressure drop is ± 10%.

Each type air filter in use after a period of time, due to capture the various filters filter material surface dust, so that the filtering efficiency of air filter and air filter resistance to drop, affects the central air conditioning unit or clean engineering supporting efficient delivery of air supply outlet, cleanliness and efficiency, the need to replace the air filter in time, to ensure that the air cleanliness requirements. 

All kinds of air filters and hepa filters are not allowed to tear or open the packaging bags or film by hand before installation.Air filters should be stored in strict accordance with the direction standards marked on the hepa packing case.In the process of hepa filter handling, should be handled, put, avoid violent vibration and collision.
