Frequently Asked Questions
-
Q: What is the typical lifespan of this filter?
A: Lifespan depends on operating conditions and dust load. In standard HVAC applications, the filter can last 3–6 months before replacement is needed. The polyester media can be cleaned by vacuuming in some cases, but replacement is recommended for optimal performance. -
Q: Can I use this filter for high-temperature applications?
A: The maximum continuous operating temperature is 80°C (176°F). For higher temperatures, please inquire about our specialized media options (e.g., fiberglass or metal mesh). -
Q: Is the flange-clamp frame reusable?
A: Yes, the metal frame is designed for multiple uses. You can replace only the filter media if you prefer; however, we recommend replacing the entire unit for best sealing and performance. -
Q: Do you provide custom sizes?
A: Absolutely. We can manufacture filters in any non-standard dimensions. Please provide your exact requirements (length, width, depth) and we will confirm feasibility and lead time. -
Q: What does the Mill Test Report include?
A: The report contains data on material composition, tensile strength, bursting strength, thickness, and weight per square meter. It confirms that the polyester media meets the specified quality standards. -
Q: Is this filter washable?
A: Polyester filters are not typically washable due to potential media damage. However, they can be lightly vacuumed to extend service life. For washable options, we recommend our stainless steel mesh filters. -
Q: What certifications do you hold?
A: As a manufacturer, we follow internal quality control procedures. Specific certifications (e.g., ISO) are available upon request for certain product lines. Please contact us to discuss your certification needs. -
Q: How is the filter packaged for shipment?
A: Each filter is individually packed in a poly bag, then stacked in cartons or wooden crates for export. We ensure proper protection to prevent damage during transit.
