"Micro Cooling Fan" Low noise: compact and reasonable structure design, precision manufacturing hub, in line with the perfect combination of aerodynamic propeller blade fan ensures low noise performance, the staff even stood in front of the fan can be laughing.Minimal assembly: no on-site installation, all are factory pre-installed and debugged, saving you valuable time. So we designed the project to fully take into account, to avoid the tedious installation procedures to meet your most urgent needs cool. As long as you use bolts with brake fixed on heavy-duty casters, plug 220V 16A socket can be."Micro Cooling Fan" Durable: All frames are powder-coated surface treatment, the color is more aware of safety yellow, hard and durable surface. At the same time high-performance gear, precision assembly of the gearbox more prolonging its life. Precision machining of wheels after the liquid treatment also ensures a close fit and rotationally driven balancing."Micro Cooling Fan" Versatility: simply adjust from the ground to the roof of any level can achieve an orderly flow of air. In particular, also for narrow aisle, there is the top of the obstacle, narrow work space, low ceiling spaces can be fully used freely, ventilation and cooling fully meet your needs.
