\u2014<\/p>\n
## Comprehensive Product Description<\/p>\n
The **H Class filter cartridge (Part No: 881758)** has been developed for the highest filtration requirements, especially for systems handling health-hazardous, carcinogenic materials. This filter cartridge guarantees maximum filtration efficiency, ensuring the air cleanliness is maintained at a critical level.<\/p>\n
The filter cartridge is specifically optimized for filtering dust with concentrations **below the OEL (Occupational Exposure Limit \u2013 Arbeitsplatzgrenzwert)**, i.e., **below 0.1 mg\/m\u00b3**. This specification makes it ideal for special applications such as extracting carbon fiber (CFRP) dust, where the strictest occupational safety regulations must be met.<\/p>\n
### Key Features and Benefits<\/p>\n
This filter insert is a crucial component of the Wiel\u00e4nder+Schill NA7-26 Wet Separator system, ensuring effective separation by introducing dust particles into the liquid and harmlessly binding them.<\/p>\n
* **Outstanding Filtration Efficiency:** The filter cartridge offers the highest filtration performance, ensuring a maximum penetration rate of **less than 0.005%**. This extremely low value guarantees clean air in the work area.
\n* **H Class Compliance:** The filter cartridge fully complies with the stringent **H Class** dust requirements, which is essential for the safe handling of hazardous and carcinogenic dusts.
\n* **Area of Application:** Recommended for industrial environments where the **AGW** < 0.1 mg\/m\u00b3, including the extraction of aluminum and magnesium dusts, as well as CFRP (carbon fiber reinforced plastic) dusts.\n* **Wet Separation Principle:** The filter cartridge operates as part of a wet separation system, where dust particles are directed into a liquid medium, thereby effectively binding and removing them in a non-dusting form.\n\n---\n\n## Technical Data\n\nThe table below summarizes the critical technical parameters of the H Class filter cartridge:\n\n| Property | Value | Note |\n| :--- | :--- | :--- |\n| **Product Name** | Filter Cartridge H | |\n| **Compatibility** | NA7-26 Wet Separator | |\n| **Part Number** | 881758 | |\n| **Dust Class** | H | Complies with the highest filtration standards. |\n| **Maximum Penetration Rate** | < 0.005% | Extremely high filtration efficiency. |\n| **Recommended OEL** | < 0.1 mg\/m\u00b3 | Ideal for hazardous dusts. |\n| **Application Area** | Handling of Carcinogenic Materials | Also suitable for CFRP dusts. |\n\n---\n\n## Related Accessory: NA7-26 Wet Separator (881760)\n\nFor the optimal functioning of the filter cartridge, the use of the corresponding **NA7-26 Wet Separator** (Part No: 881760) is essential. This system ensures the safe and effective binding of dusts.\n\n### Advantages of the Wet Separator\n\nThe wet separator system offers numerous advantages that increase efficiency and user convenience:\n\n1. **Precise Pressure Indication:** Allows for accurate monitoring of differential and negative pressure, helping to assess the filter status.\n2. **Simple Maintenance:** Enables easy emptying and cleaning.\n3. **Convenient Filter Replacement:** The filter cartridge can be replaced quickly and easily.\n4. **High Performance in Compact Size:** The device provides high performance while maintaining its compact physical dimensions.\n5. **Effective Unit Cooling:** Ensures the device is kept at optimal temperatures even during intensive use.\n6. **Optical Level Monitoring:** The visual monitoring of the fluid level is supplemented with an auxiliary level sensor for even greater safety.\n\n### Scope of Delivery for the Wet Separator (881760)\n\nThe complete system includes the following components, ensuring it is ready for immediate operation:\n\n* 1 pc Wet Separator NA7-26\n* 1 pc Accessory Box\n* 1 pc Hose Holder (stainless steel, mounted)\n* 1 pc Cable Holder (stainless steel, mounted)\n* 1 pc Suction Lance (350 mm, \u00d8 20 mm)\n* 1 pc Plastic Hose (5 m, \u00d8 50 mm)\n* 1 pc Curved Hand Nozzle (with connectors on both sides, \u00d8 50 mm)\n* 1 pc Hand Nozzle (1000 mm, \u00d8 50 mm)\n* 1 pc Industrial Floor Suction Nozzle (500 mm width)\n* 1 pc Adapter: Connection A (with 50 mm external diameter pressure coupling) and Connection B (Storz C 50 mm coupling)\n* 1 pc Crevice Suction Head (60 x 12 mm, angled)\n* 1 pc Mains Connection Cable (10 m)\n\nThis filter cartridge is therefore not just a spare part, but a fundamental element of safe and efficient industrial vacuuming, especially for dusts posing the highest health risks.\n<\/p>","protected":false},"excerpt":{"rendered":"
