Frequently Asked Questions (FAQ)
-
Q: What is the maximum temperature this filter cartridge can withstand?
A: The polyester needle felt cartridge is rated for continuous operation up to 240°C. For short-term spikes, it can tolerate slightly higher temperatures, but prolonged exposure above 240°C may reduce service life. -
Q: Can I use this cartridge for oil mist or wet dust?
A: Polyester needle felt has good moisture resistance, but for heavy oil mist or high humidity, we recommend a PTFE-coated version or hydrophobic treatment. Please consult our sales team for specific conditions. -
Q: How often should I replace the filter cartridge?
A: Replacement frequency depends on dust load, operating hours, and cleaning efficiency. Typically, these cartridges last 6–12 months in moderate conditions. Regular monitoring of differential pressure helps determine optimal replacement timing. -
Q: Do you provide samples for testing?
A: Yes, we offer sample cartridges for evaluation. Please contact us with your application details, and we can arrange a sample shipment. -
Q: What cleaning methods are compatible?
A: This cartridge works well with pulse-jet cleaning, reverse air, and mechanical shaker systems. The felt structure is designed to release dust with minimal energy input. -
Q: Can I get custom dimensions for my existing dust collector?
A: Absolutely. We provide custom lengths, diameters, and end cap configurations to fit your equipment. Send us your specifications, and we will produce a perfect match. -
Q: Is this product suitable for food-grade applications?
A: Polyester needle felt is generally inert and safe for food contact if used in dry powder handling. For direct food contact, please verify with local regulations and consider additional certifications. We can discuss options. -
Q: What is the lead time for bulk orders?
A: Standard lead time is 15–25 working days, depending on quantity and customization. With our factory located in Hengshui, Hebei, and shipment ports in Tianjin, Qingdao, Shanghai, and Foshan, we ensure timely delivery worldwide.
