PTFE membrane filter material｜Process material adaptation｜FFU and EFU matching
Aili Industrial PTFE ULPA ultra-high efficiency filter uses PTFE membrane filter material, combined with filter element, frame, packaging and installation seal to form a complete filter assembly. It is used in clean air supply locations with clear requirements for particle control and material adaptation.
Product selection is based on process conditions, while confirming the filtration level, operating air volume, pressure drop, size and installation interface. U15, U16, and U17 configurations can be evaluated according to project requirements. The specific performance is subject to the specifications and testing data of the corresponding model.

PTFE is the filter material configuration, and ULPA is the filtration performance level. Filters using PTFE filter material still need to confirm the filtration grade through corresponding finished product testing.
Product selection involves not only membrane materials, but also support materials, filter element packaging, frames and installation seals. When the process has requirements for materials, the specific items that need to be controlled should be clarified and the complete filter assembly should be confirmed.

For equipment projects that clearly require PTFE filter material, the configuration can be confirmed based on particle control objectives and material requirements. The filter material selection is matched with the equipment purpose, use environment and verification requirements.
Product resistance should be compared at specified air volumes. Aili Industrial can combine the filter material, filter area and filter element thickness to confirm the air volume and pressure drop data of the corresponding configuration to provide a basis for equipment fan matching.
The outer frame size, total thickness, fixed position and sealing interface can be confirmed according to the equipment drawings, and the installation method of gasket sealing or liquid tank with corresponding knife edge structure can be adapted.
For projects with clear material restrictions, filter material and other component information can be confirmed as agreed. When it comes to material release or process compatibility, test items and acceptance conditions should be clearly defined.

The specific air volume, resistance, usage environment and delivery configuration of the product are subject to the corresponding model specifications and confirmed drawings.
The operating resistance is affected by the filter material, filter area, filter element structure and air volume. When purchasing, you should compare the data of specific models. You cannot judge that a product must have lower resistance based on 'PTFE' alone.

When used for FFU and EFU, the air volume, wind speed and operating status of the entire machine should be checked at the same time.
The material properties of PTFE filter material cannot directly represent the use range of the entire filter. Temperature, humidity, process media and maintenance conditions should be checked with all components.

In the presence of water mist, condensation or chemical media, the suitability of the complete filter assembly should be assessed first. PTFE filter material does not mean that the filter can be washed directly or washed repeatedly.
According to the unit size and design air volume, confirm the thickness, pressure drop and sealing method of the PTFE ULPA filter. Combined with the fan working point and replacement structure, confirm the operation and maintenance conditions of the entire machine.
Combined with the internal space of the equipment, process material requirements and local air supply range configuration. For small-sized or thin EFUs, the filter area, pressure drop and air outlet uniformity need to be evaluated at the same time.
Aili Industrial can collaboratively confirm filters, fans, boxes and installation interfaces, and provide product support for equipment supporting projects.

Whether the product is suitable should be confirmed based on specific process conditions. After the filter is installed, verify the actual clean air supply performance according to the equipment or project requirements.
When the original equipment uses other filter materials, the performance and interface should be rechecked when replacing it with PTFE ULPA filter.

Handle the filter by its frame to avoid touching, pressing or scratching the filter media. Before installation, check the appearance, seals and air flow direction, and fix and seal according to the equipment requirements.
Record the air volume and corresponding pressure difference in the early stage of operation, and then determine the timing of maintenance and replacement based on pressure difference changes, actual air volume, leak detection results and process requirements.
When the filter material is contaminated or damaged, you should first confirm the treatment method and avoid using solvents, compressed air or cleaning methods on your own.
Aili Industrial independently produces air filters, and also has the capabilities of motor manufacturing, independent research and development and production of fans, control system development, sheet metal processing and complete machine assembly.
For the PTFE ULPA filter project, we can jointly confirm the filter material configuration, operating resistance, installation interface and equipment matching requirements, and support sample selection, replacement parts customization and bulk purchase.
