As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to offer this Custom Industrial Dust Filter Element designed for demanding industrial environments. Engineered with a dual-stage filtration system including a pre-filter and a true HEPA stage, this cartridge ensures high-efficiency particle capture while maintaining robust airflow. With a 4-inch inner diameter and 12-inch length, it fits a wide range of dust collectors, and its 120V-240V compatibility makes it suitable for global installations. Whether you need to control fine dust, fumes, or airborne contaminants, this filter element delivers reliable performance backed by decades of manufacturing expertise.
Key Features & Technical Specifications:
- Dual Filtration Stage: Integrated pre-filter captures larger particles (e.g., sawdust, metal shavings) extending HEPA life; HEPA stage removes ≥99.97% of particles ≥0.3 microns.
- Universal Voltage: Compatible with 120V-240V AC power supplies, allowing seamless integration into different regional electrical systems.
- Standard Dimensions: 4-inch inner diameter (ID) and 12-inch length – a common size for many industrial dust collectors, with customization available for non-standard requirements.
- Durable Construction: Media options include fiberglass, polyester, or synthetic blends, supported by a rigid metal or plastic core for structural integrity under high airflow.
- Easy Maintenance: Replaceable cartridge design minimizes downtime; pre-filter can be cleaned or replaced separately to reduce operational costs.
- Wide Application: Suitable for woodworking shops, metal fabrication, pharmaceutical processing, food production, and general industrial ventilation.

Frequently Asked Questions (FAQ):
Q1: What is the difference between the pre-filter and the HEPA stage?
A: The pre-filter is designed to capture larger particles (e.g., dust, debris), protecting the HEPA element from clogging prematurely. The HEPA stage then removes sub-micron particles with high efficiency (≥99.97% at 0.3 μm). Together they provide extended filter life and superior air purity.
Q2: Can the voltage be adjusted for my specific region?
A: Yes, the filter element is compatible with 120V-240V AC power supplies. However, please note that the voltage compatibility applies to the integrated fan or motor (if applicable) – the filter media itself does not require power. If you need a specific voltage variant, our team can customize the electrical components accordingly.
Q3: Is this filter element suitable for use in explosive dust environments?
A: Standard models are not ATEX or IECEx certified. For explosive dust applications, we recommend using our conductive media or anti-static options. Please contact us to discuss your specific hazardous area classification.
Q4: How often should I replace the pre-filter and HEPA cartridge?
A: Replacement frequency depends on dust load and operating hours. Typically, the pre-filter may need cleaning or replacement every 1-3 months, while the HEPA element lasts 6-12 months. We recommend monitoring differential pressure across the filter to determine optimal change intervals.
Q5: Can you provide a filter with a different inner diameter or length?
A: Absolutely. Our factory specializes in custom solutions. You can request variations in inner diameter, length, outer diameter, gasket type, and media. Minimum order quantities may apply – please inquire with our sales team.
Q6: What certifications does your factory hold?
A: As a manufacturer, we focus on quality control and have internal testing procedures. While we do not list specific third-party certifications in this description, we can provide test reports upon request. For certified filters (e.g., UL, CE), please discuss your requirements with our engineers.
Q7: How do I install this filter element?
A: The filter is designed to be a direct replacement for many standard dust collector cartridges. Simply slide the new element onto the mounting flange, ensure the gasket seals properly, and secure it with the existing clamp or bolt. Detailed installation instructions are included with each shipment.
Q8: What is the typical lead time for custom orders?
A: For standard sizes, we ship within 7-15 business days. Custom orders may require 15-30 days depending on complexity. We recommend contacting us early to schedule production for large quantities.
