How to properly install the air filter 

1.Installation of air filters for clean rooms

2.W type air filters

Basic installation principles:

Type W air filters use the same mounting frames as fiberglass bag air filters and are secured with clips. For W type air filters of classes H10 and H13, it is necessary to use frames with better tightness and more powerful clamping mechanisms (tightening with bolts at the corners of the frame). It is necessary to ensure tightness between the frames, for example, using sealant.

The filter media of W type air filters (white pleated part, fiberglass filter paper) is more susceptible to damage than the filter media of fiberglass bag air filters. When installing/moving, hold the filter by the outer frame without touching the white filter material. Watch the position of your fingers when holding the frame. Inexperienced workers often unintentionally damage filter paper.

Correct installation:

Step 1: Hold the outer frame of the filter with both hands, insert the larger part of the filter into the mounting frame and stabilize its position;

Step 2: Insert your hands into the V-channel of the filter. Attention: Do not touch the filter paper;

Step 3: Press the filter top cover with both hands, lift the filter slightly, and carefully insert it inside, pressing it firmly against the mounting frame.

Step 4: Lock the clamping mechanism. How to install the high efficiency filter without baffles:

1. During transportation and storage, the high-efficiency air filter should be placed in accordance with the manufacturer's labeling instructions. During transportation, it should be handled with care, avoiding strong vibrations and shocks:

2.Before installing the high-efficiency air filter, it is necessary to clean and wipe the clean room, and remove dust from the internal parts of the cleaning system to ensure that cleanliness requirements are met;

3.At the installation site, unpack the filter and check its condition, including filter paper, frame, sealing gasket, dimensions, etc. The thickness of the sealing gasket should not exceed 8mm, and there should be no leakage at the frame joints:

4.When installing, the arrow on the outer frame of the filter must coincide with the direction of the air flow. In the case of unidirectional flow, the difference between the nominal resistance and the average resistance of each filter installed in the same air intake or on the same supply surface must be less than five percent.

How to install a high efficiency baffle filter:

Before installing the H14 baffle filter, the ventilation ducts of the air purification system must be thoroughly cleaned. Typically, before hanging the ducts, the inside walls are first cleaned with detergent or alcohol, then the inside of the air conditioning unit is washed, and then the pre- and mid-filters are installed or cleaned. The clean room is then thoroughly cleaned and wiped down. If dust has accumulated inside the air conditioning system, it should be removed and wiped down again until the required level of cleanliness is achieved. If high-efficiency filters are installed in a technical space between floors or in a suspended ceiling, then these areas must also be thoroughly cleaned and wiped down.

The frame for installing the H14 filter with partitions must be level; the permissible deviation in the flatness of the mounting frame of each high-efficiency filter should not exceed 1 mm; The surface of the plenum chamber must be coated with a paint with high resistance to aging.

When installing the high efficiency air filter, the arrows on the outer frame must align with the direction of the air flow; When installed vertically, the folds of the filter paper should be perpendicular to the floor.

Recommendations for installing air filters without baffles/with baffles:

1. The inner plastic packaging of filters without/with partitions must be opened only in a clean room;

2.When carrying and installing the filter, hold it by the outer frame with both hands;

3. To install large filters, at least two people are required; pay attention to the need to protect the sealing gaskets;

4.Do not support the filter with your hands by its central part;

5.Do not touch the inner filter material of the filter.

Conclusion

1.After dismantling the old filter, you need to clean the filter frame and related equipment, and then install the new filter.

2.After completing the installation of the filter, you should check that it is installed correctly and make sure that the front and rear measuring tubes are in place;

3.Make sure the frame is tight and replace damaged gaskets.

4. Make sure that the connections between the frames are tight; If necessary, a special low volatility sealant can be used.
