CHARACTERISTICS
- 1.Equipped with external rotor AC motor embedded inside the impeller for excellent heat dissipation, supporting 24-hour continuous operation.
- 2.7-blade stamped stainless steel impeller with factory dynamic balance calibration, low vibration, low noise and uniform airflow.
- 3.Integrated metal duct with black powder coating, anti-rust and corrosion-resistant; standard diameter fits common round ventilation ducts.
- 4.Three configuration options to flexibly match different installation methods and protection requirements.
Applicable scenarios
- · General: Industrial workshop ventilation, warehouse air circulation, equipment cooling, HVAC duct supply/exhaust, drying line ventilation.
- · Standard (no grill): In-duct series installation, equipment cavity embedding and other fully enclosed impeller conditions.
- · Standard + Grill: Duct ends, wall air outlets, equipment exterior and other exposed impeller scenarios.
- · Standard + Grill + Base: Spot air supply, temporary site ventilation, floor-standing use without drilling conditions.
Advantages
- 1.Cylindrical air-gathering structure with low wind resistance and high air pressure, long delivery distance and high ventilation efficiency in ducts.
- 2.External rotor motor + stainless steel blades for stable and durable performance, suitable for dusty and normal-temperature industrial environments.
- 3.Complete configuration coverage, one-stop selection from in-duct to floor-standing use, matching different project requirements.
- 4.Modular design for easy duct connection; removable grill and base for convenient daily cleaning and maintenance.
