The self-purifying transfer window, also known as the dynamic transfer window, is a material transfer equipment with a fan filtering and air supply function. The fan drives the air to pass through the filter, and forms an air circulation in the transfer chamber through the designed air supply and return air paths, which is used to control particles in the air in the cavity, and cooperates with door interlocking to complete material transfer.
Compared with conventional static transfer windows, self-purifying transfer windows add fans, filters, air ducts and operation controls. Whether the equipment is suitable needs to be judged based on the material characteristics, loading method, regional conditions on both sides and process requirements.
Aili Industrial can provide self-cleaning transfer window configuration and non-standard customization support based on the installation space, material size, filtration requirements and control process. Workstations that do not require circulation filtering function are comparableMechanical interlocking transfer window ; pay attention to the items of door opening permission and operation prompts to learn moreElectronic interlocking transfer window。
Fan and filter co-configuration
According to the inner cavity size, filter resistance, air return path and target operating conditions, confirm the configuration of the fan and filter to match the air supply system and the box structure.
Arrange the return and return air paths around the material
Determine the air supply coverage and return air channel based on the material height, pallet size and placement position. Necessary air paths must be maintained after items are placed to reduce the impact of occlusion on circulation purification.
Purification operation and door control linkage
Start after closing the door, purification operation prompts and unlocking conditions can be set according to the project, so that the loading, purification and retrieval steps can be connected with each other. The specific procedures and running time should be determined based on the process and test results.
Monitoring configuration is selected according to needs
Corresponding pressure difference indication, operating status or alarm functions can be configured according to usage and acceptance requirements. Filter resistance monitoring and cavity external pressure difference monitoring should be defined separately to avoid confusion.
Consider filter replacement and maintenance ahead of time
Combined with the wall installation location, edging and surrounding space, determine the filter disassembly and installation, fan maintenance and control component inspection methods to reduce the structural obstruction of later maintenance.

Whether to use a self-purifying configuration should be determined by process requirements. If the focus is on air purging the outer surface of the material, you can further compareAir shower transfer window。
Put in materials that have been processed as required
Before loading, complete the necessary cleaning of the outer packaging or material surface according to on-site procedures. Materials should be placed in specified areas to avoid blocking the air supply surface, return air outlet or affecting door closing.
Close the door and confirm the status
After the door is closed, the system starts or maintains purification operation according to the set conditions. When process linkage is required, the relationship between door status detection, fan operation and unlocking conditions should be confirmed.
Complete purification according to set procedures
Run times need to be determined based on material loading, airflow conditions and field testing. The purification and recovery conditions of the same equipment may be different in unloaded and loaded states.
Allow contralateral side to pick up objects and complete handover
After the agreed release conditions are met, the person on the opposite side opens the door to retrieve the object, and then closes the door. The actual procedures are subject to equipment configuration and on-site operation requirements.
Identify the pollution objects that need to be controlled
First distinguish between air particles, material surface contamination and microbial control needs. Air filtration is not a direct substitute for material surface cleaning or appropriate disinfection processes.
Check the air path based on actual loading status
Provides maximum material, pallet and typical placement. The air path cannot be designed based only on the cavity. The obstruction, return air gap and pick-and-place movement after loading also affect the operation.
Confirm cleanliness level together with test conditions
If the project requires a specific cleanliness level, the test status, loading conditions, sampling location and detection method should also be agreed upon. It cannot be determined based on the names of 'self-cleaning' or 'dynamic'.
Confirm two types of pressure difference monitoring separately
The pressure difference before and after the filter is mainly used to understand the resistance changes of the filter and the system; the pressure difference between the cavity and adjacent areas involves the regional air flow relationship. The two have different uses and should be designed separately.
Provide conditions for leak detection and replacement
If there are filter leak detection requirements, the test interface, accessible location and sealing structure should be confirmed in advance. Also check whether changing the filter requires access to adjacent areas or removal of edging.
Projects with special dimensions, door positions or limited installation space can beNon-standard customized delivery window for further confirmation.
Aili Industrial has the manufacturing capabilities of motors, fans, control systems, sheet metal processing, air filters and complete machine assembly. It can jointly check the filtration configuration, fan working conditions, box air path and door control procedures.
For different materials and installation stations, Aili Industrial can cooperate to confirm the inner cavity size, filter sealing, maintenance space and operation control, and provide supporting support according to the test content agreed on the project. When stainless steel structure is required, it can be combined withStainless steel transfer windows specify the material range and surface treatment.
In common product classifications, both usually refer to transmission equipment with fan filtering and air supply functions. The air supply and return structure, control procedures and monitoring configurations of different solutions may be different, and the specific configurations still need to be checked.
It cannot be determined by name alone. The cleanliness target, test status, sampling location and loading conditions need to be agreed upon and confirmed through corresponding testing.
There is no uniform time that applies to all projects. The size of the inner cavity, air volume, initial particle state, material placement and acceptance goals will all affect the recovery process and should be determined based on testing.
This cannot be judged directly. HEPA filtration mainly controls particles in the airflow. Adherent contamination on the material surface, packaging processing and disinfection requirements need to be managed separately.
Continuous or intermittent operation can be selected according to the process. The cavity status during standby, the recovery process after restart, and operation management need to be considered at the same time.
It should be judged based on the running time, environmental load, filter pressure difference, test results and maintenance requirements. It is not suitable to use the same month as the basis for the replacement of all equipment.
The self-purifying model focuses on filtration and purification of cavity air;The air shower transfer window focuses on using the nozzle airflow to blow the surface of the material. The selection should be based on the pollution control objectives, whether the material is allowed to be purged and the actual process.
The self-purifying transfer window needs to confirm the materials, air path, filtration configuration and door control process at the same time. Provide clear loading methods, purification goals and installation conditions to help determine suitable product solutions.
