Core advantages‌

1. Powerful & Stable Output – Filtration Efficiency Foundation

Features a high-efficiency, high-static pressure impeller with a maximum air volume of 20,710 m³/h, meeting the high air change demands of critical medical areas like operating rooms and ICUs. With a max static pressure of 2,000 Pa, it easily copes with multi-stage filtration resistance, maintaining stable air velocity and consistent air cleanliness.

2. Precise Intelligent Control – Stable Operating Conditions

Equipped with a high-efficiency EC motor (supports 0~10V/PWM/RS485 & BMS linkage). Dynamically adjusts air flow/pressure to adapt to filtration resistance and pressure requirements, avoiding efficiency loss or microbial contamination. 

3. Medical-Grade Anti-Microbial Design – No Secondary Pollution

The aluminum alloy impeller is corrosion-resistant, enduring UV, ozone, and chemical disinfection. Streamlined wide-backward blades minimize dust buildup, eliminating microbial breeding grounds and ensuring clean, safe air supply.

4. Low-Noise & Low-Vibration – Medical Comfort Compliance

Aerodynamically optimized impeller + silent bearings + G2.5 dynamic balance. Reduces turbulent/mechanical noise, avoiding interference with medical procedures, patient rest, and precision testing.

5. High Reliability – Ready for 24/7 Continuous Operation

Validated by 40,000 hours of reliability testing. IP54 protection resists disinfectant spraying and condensed water, while Class F insulation (155℃ heat resistance) ensures stable, long-term compliant operation in harsh medical conditions.

6. Modular Quick-Disassembly – Reduced Life-Cycle Costs

Modular design simplifies transportation, installation, and routine maintenance (e.g., filter replacement, internal cleaning). Lowers downtime and operational labor costs for medical facilities.

FAQ

• Q: Can this EC high static pressure fan adapt to high-resistance purification environments such as hospital operating rooms and PCR laboratories?

  A: Custom-designed with high static pressure for medical AHU air handling units. It easily overcomes resistance from multi-stage filters, long ducts and valves, stably maintains positive and negative pressure in clean areas, and fully meets high-resistance ventilation demands of medical scenarios.

• Q: With frequent disinfection in medical environments, will the fan be corroded or breed bacteria to cause secondary pollution?

  A: Adopts anti-corrosion coating and fully sealed structure, resistant to disinfectant mist and high humidity. The surface is dust and mildew resistant with low air leakage, effectively avoiding secondary air pollution and complying with medical clean standards.

• Q: What are the advantages of EC fans over traditional AC fans for long-term operation in hospitals?

  A: Equipped with high-efficiency EC permanent magnet motors for outstanding energy-saving performance in year-round continuous operation. Belt-free structure requires zero daily maintenance, greatly reducing shutdown and maintenance risks in medical areas.

• Q: Can the fan connect to the hospital building automation system for intelligent air volume and pressure regulation?

  A: It supports 0-10V, PWM and Modbus communication with stepless speed regulation. Built-in constant pressure and constant air volume modes allow linkage with BAS systems to automatically compensate air volume loss caused by filter clogging.

• Q: Does the product meet strict noise and stability requirements of special medical areas?

  A: Optimized aerodynamic design and precision dynamic balance ensure low noise operation. With wide temperature adaptability and multi-overload protection, it supports 24/7 stable continuous operation, suitable for quiet environments of wards and laboratories.
