Frequently Asked Questions
1. What is the difference between a flange-clamp filter and a standard bag filter?
Flange-clamp filters have an integrated metal frame with a clamp mechanism that seals directly into the holding frame, eliminating the need for separate gaskets. Standard bag filters often require additional sealing. Our design provides a more reliable, leak-proof installation.
2. Can this filter be used in high-humidity environments?
Yes, the polyester media is moisture-resistant and can operate in up to 100% relative humidity (non-condensing). The galvanized steel frame resists rust, making it suitable for humid industrial areas.
3. What is the typical lifespan of this filter?
Lifespan depends on operating conditions and dust load. For general HVAC applications with moderate dust, the filter typically lasts 6–12 months before reaching the recommended final pressure drop. Regular monitoring is advised.
4. Do you offer custom sizes?
Absolutely. We can produce any size within reasonable limits. Custom dimensions are available upon request with a minimum order quantity. Please contact our technical support team for details.
5. How do I know which filter grade (G3, F7, etc.) to choose?
The choice depends on the required indoor air quality and the particle size you need to capture. For example, G3 filters are suitable for pre-filtration, while F9 filters capture fine dust. Our free technical support can help you select the optimal grade based on your application.
6. Is the filter washable or disposable?
This is a disposable filter designed for single use. Washing may damage the media structure and reduce efficiency. For reusable applications, we recommend our cleanable metal mesh filters.
7. What certifications does your factory hold?
While we do not claim unspecified certifications, our products are manufactured in compliance with international standards such as EN 779 and ASHRAE 52.2. Test reports are available for each batch upon request. Our factory has been audited by many international buyers.
8. How do I place an order or request a sample?
You can contact us via our website or email. We offer free samples for evaluation (shipping cost may apply). Our sales team will provide a quotation within 24 hours.
