1, YWF fans with features of compact structure, stable running, low noise convenient insulation, high effeciency etc.
2, YWF fans divided into single phase capacitor operation and three phase asynchronous operation, widely used for evaporator, condenser, water cooler, heat pump and venrilation.
23, YWF 100% speed control motor with low staring current, protection class of IP54, and insulation of grade B and F.
4, Single phase capacitor operation motor supplied with thermal protector, three phase motor supplied withour thermal protector, if customer have special using, pls keep us informed before order. Our fans can be used in ambient temperature of -30to degree.
5, Voltage: Single phase motor normally running at 220V/50Hz/60Hz, three phase motor normally running at 380V/50Hz/50Hz, But we can produce according to different requiement of voltage and frequency.
6, YWF fans can be controlled speed by frequency transformer or voltage inverter, three phase fans can be adjusted double-speed by Y/ exchanger, or variety speeds by different connection. Also we can control speed by adjusting input voltage with SCR manually.
7, If customer need our motor used for their own centrifugal impeller, we need to know the operating points, power, installation details, better provide the samples of impeller and housing.
8, Airflow curve(static pressure & volume) RETEK airflow curves measured in the air density of 1.2kg/cbm, ambinet temperature of 20 degree. C, according to national standard.
9, Noise value: It is sound pressure level of noise value in our technical data, achieved at the point of 1m from inlet, according to national standard.
10, Average lifetime
RETEK fans installed with ball bearing, average lifetime between 30000 to 50000 hours base on different environment/condition of using.
11, Motors can be supplied with cable directly or IP54 junction box, we can also supply specially as customer's requirements.
