Frequently Asked Questions (FAQ)
The cartridge is made of Polypropylene (PP). It features outstanding chemical stability, offering high resistance to strong acids, strong alkalis, and various organic solvents like ethanol and acetone.
The standard filtration accuracy ranges from 0.1μm to 100μm. Custom specifications such as 0.3μm, 1μm, and 5μm can also be tailored to meet your specific filtration requirements.
The conventional operating temperature range is -30°C to 100°C (with short-term limits up to 125°C for specific models). The standard working pressure is ≤0.4MPa, though high-pressure models can withstand up to 50bar.
Yes. Thanks to their durable structural design, the cartridges can be regenerated through back-washing processes, resulting in a high reuse rate and long service life.
Absolutely. The filters are constructed without any adhesives, fully aligning with FDA and GMP standards, making them highly suitable for sensitive applications in the food, beverage, and pharmaceutical industries.
