**5. Why Choose the Jienengrui JH Series?**

| Comparison Dimension | Jienengrui JH Series | Ordinary Industrial Vacuum / Non-Professional Fume Equipment |

| :--- | :--- | :--- |

| **Filtration System** | **PTFE coated filter cartridges**, designed specifically for 0.1-0.3μm welding fumes, offering high filtration precision and long life. | Ordinary filter bags or primary filter elements, ineffective at filtering sub-micron fumes. |

| **Control Logic** | **Intelligent constant pressure & frequency conversion**, providing stable, self-adapting airflow, saving energy and protecting core components. | Typically uses direct-on-line starting with fixed frequency, resulting in fixed airflow, high energy consumption, and susceptibility to overload. |

| **Cleaning Method** | **Programmable rotating reverse pulse**, enabling automatic, efficient cleaning to maintain stable system pressure differential. | Manual cleaning or simple shaking, which is inefficient and less effective. |

| **Design Positioning** | Designed specifically for **continuous, heavy-duty welding fume conditions**, featuring robust construction and durable components. | Mostly designed for intermittent cleaning tasks, unable to withstand continuous high-temperature fumes. |

| **Authoritative Endorsement** | Possesses **CE certification, RoHS certification, relevant utility model patents, and知名企业 (well-known enterprise) application cases**. | Lacks industry-authoritative certifications and support from large project cases. |
