How to control the ULPA warehouse environment? Temperature, humidity and spare parts storage

ULPA filter storage should follow the environmental and packaging requirements of specific products to prevent moisture, extrusion, contamination and accidental collision. Spare parts management also requires the retention of batches, storage times and storage status. The factory inspection only represents the status at the moment of delivery. If the storage process from storage to collection is out of control, the filter material and seals may still change. Aili Industrial has a standardized warehousing management process at the production base. From the filter element coming off the line and entering the warehouse to loading and leaving the warehouse, the records are recorded and saved in a controlled environment. This set of management experience can be directly transformed into spare parts storage suggestions for the client, so that every filter element received by the customer has a traceable storage record.

1. Determine the environment according to the model, and do not apply the restrictions of other products

Record temperature, humidity and abnormal exposure, and avoid areas with condensation, water leakage, chemical contamination and strong vibration. Do not take the storage restrictions of other models directly as conditions for this product.

Different filter materials, sealing materials and frame forms have different sensitivities to temperature and humidity. Storage conditions should be implemented according to the product instructions of the specific model. Aili Industry isWhen HEPA/ULPA filters are delivered, corresponding storage condition instructions will be provided with the product, instead of sharing a set of general requirements for all models; high-humidity-sensitive models, high-temperature-resistant models, and chemical environment models each have corresponding environmental parameters. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。

2. Keep packaging and stress correct, and stacking is not random.

Store according to the prescribed posture and stacking requirements to avoid heavy objects pressing on the filter surface. Spare parts with damaged packaging or long-term exposure should be individually marked for evaluation.

Most of the damage to filter elements in warehousing comes from packaging pressure and incorrect posture: the number of stacking layers exceeds the limit, heavy objects press on the packaging box, and the filter element is placed vertically instead of flat, resulting in a change in the direction of stress, which will cause imperceptible changes in the outer frame and glue seams. Aili Industry marks the number of stacking layers and storage posture requirements on product packaging. In warehousing management, there are clear specifications for the posture and stacking of products in storage. This set of specifications is provided to customers along with product packaging instructions as a basis for warehouse placement.non-standard ULPA filters can be specified separately at the time of delivery.The packaging support and stacking requirements for large-size models of

3. Establish pre-use inspection. First-in, first-out cannot replace status confirmation.

Confirm the serial number, model, storage records and sealing material status, and decide whether to conduct additional testing based on the storage time and abnormalities. First in, first out is not a substitute for status confirmation.

First-in-first-out solves the problem of time order, but cannot solve the problem of saving state. The temperature and humidity of the same batch of filter elements stored near the door may fluctuate more, and the packaging near the window may be affected by sunlight. These differences will not be reflected in the storage date. Aili Industrial's warehousing management records the batch status of the products in stock. After an abnormality is exposed, the specific batch can be located. This approach can be transformed into the client's spare parts ledger: recording the warehousing batch, storage location and abnormal events, and determining whether additional inspections are required based on status rather than just date when receiving. To judge the status of sealing materials, please refer toHEPA FAQs and Selection Guide。

4. Save the resume and deliver it with the product

Aili Industry isWhen the ULPA ultra-high-efficiency filter is delivered, it can provide a storage history from the production line to the delivery, including the storage time, warehousing environment and status confirmation before delivery, so that customers can not only get the factory inspection report when receiving the goods, but also know whether the storage process is under control. For spare parts that have been stored for a long time or need to be re-inspected, this history is one of the basis for judging whether additional testing is needed.

5. Related questions and answers

Can it be stored indefinitely unopened?
cannot. Complete packaging does not mean that the material condition will remain unchanged forever. It should be judged according to the model requirements and actual storage conditions.

Condensation appears after the warehouse air conditioner is shut down. What should I check?
Spare parts and packaging in the same area should be checked, and not only the average indoor humidity should be recorded. The local condensation point and the moisture content inside the package may be quite different and need to be confirmed by batch.

Does first-in-first-out ensure that the spare parts received are in good condition?
cannot. First-in-first-out only solves the time sequence, and the saving status needs to be confirmed separately, especially for batches with abnormal exposure records.
