Product Core Advantages

Military-grade Filtration Performance

Utilizing gradient glass fiber composite filter material to achieve full interception of particulates above 0.3μm, with an oil mist filtration efficiency of ≥99.5%, surpassing the ISO 8573-1 Class 1 standard.

Smart Lifespan Monitoring Design

Equipped with a built-in pressure differential indicator that provides real-time display of filter saturation status (0.5bar threshold alarm), preventing misjudgment of replacement cycles.

Full-Condition Adaptability

Temperature Adaptability: Stable operation in extreme environments ranging from -30℃ to +120℃.

Pressure Compatibility: Maintains high-efficiency filtration within a wide pressure differential range of 0.01 to 3bar.

Modular Rapid Maintenance

Patented snap-fit installation structure allows for tool-free replacement, reducing average maintenance time to just 5 minutes.

Industry Solutions

Case 1: Photovoltaic Cell Panel Sealing Test

User Pain Point: A TOPCon battery production line experienced a 30% increase in false alarm rates of ASM340W due to oil mist backflow.

Solution: Installed a customized DN25KF interface filter.

Implementation Results:

Device false alarm rate reduced to <0.5%.

Pre-pump maintenance cycle extended from 2 weeks to 3 months.

Annual maintenance cost savings of 280,000 yuan.

Case 2: Spacecraft Fuel Tank Leak Detection

Special Requirement: Stable operation in a -40℃ low-temperature environment.

Technical Customization:

Employed special low-temperature sealing materials.

Added an electric heating anti-freeze module.

Verification Data:

Continuous 500-hour -40℃ test with pressure drop fluctuation <5%.

Passed NASA-STD-8719.14 certification.

Six-Step Installation Optimization Process

Pre-cooling Treatment: Freeze new filter elements at -20℃ for 12 hours before use (only for low-temperature models).

System Depressurization: Ensure the vacuum returns to atmospheric pressure.

Sealing Surface Treatment: Clean with IPA and apply specialized vacuum grease.

Direction Alignment: Strictly align the arrow mark with the airflow direction.

Torque Control: Install using an 8N·m torque wrench.

Start-up Inspection: Run the system unloaded for 30 minutes to monitor the pressure drop curve.

Top Ten In-Depth Technical Q&A

1、Can the filter be used in conjunction with a molecular pump?

Answer: A buffer chamber needs to be installed. It is recommended to consult an engineer for a customized three-stage filtration solution.

2、How to handle conditions with corrosive vapors?

Answer: A PTFE-coated filter material version can be selected, which enhances acid and alkali resistance by 10 times.

3、How does frequent start-stop affect the lifespan?

Answer: Each start-stop cycle is equivalent to 5 hours of continuous operation. It is recommended to limit start-stop cycles to ≤3 times per day.

4、What are the considerations for vacuum grease selection?

Answer: Apiezon N-type grease is recommended to avoid secondary contamination caused by silicone-based greases.

5、Is remote monitoring possible?

Answer: The smart version supports 4-20mA signal output and is compatible with SCADA systems.

6、Is it suitable for nuclear industry environments?

Answer: A special version has passed the NQA-1 certification and has been used in the ITER project.

7、How is oil mist recycling handled?

Answer: A condensation recycling device can be provided to achieve 98% waste oil regeneration and utilization.

8、How to verify the filtration effect?

Answer: ISO 8573 certified testing services are provided to generate visual particle distribution charts.

9、Does it affect the sensitivity of helium leak detection?

Answer: Tests have shown no attenuation of sensitivity at the 1.0E-12 mbar·L/s level.

10、How long is the customization cycle?

Answer: Standard models take 3 days, while non-standard designs take 7-15 days (including performance verification).
