140mm AC 220~ 230V External Rotor Motor Forward Curved Centrifugal Fans with Plastic Impeller

140mm AC 220~ 230V External Rotor Motor Forward Curved Centrifugal Fans with Plastic ImpellerModel:PF2K140B2AS/PF2K140B2ASS / Motor: External rotor AC motor PBM Motor and Fan is a China mainland manufacturer and EC technology consulting company offering an extensive range of EC(Electronically Commutated) motors, fans and solutions, investing in the latest developing, manufacturing and technical equipment with in-depth processes & procedures. Our main products are EC fans, including EC axial fans, EC centrifugal fans and EC blowers. We do both AC and DC current type. And EC Motor is the core technology of our products. Eletronically Commutated Motors(EC Motors)also known as Brushless DC Motors(BLDC) are synchronous electric motors powered by direct-current(DC) electricity and having electronic commutation systems,rather than mechanical commutators and brushes.The current-to-torque and voltage-to-speed relationships of BLDC motors are linear. PBM fans are widely used in many fields. For example, axial fan for telecom, backward curved centrifugal fan for air exchanger,(inline duct fan)hydroponic products and FFU, forward curved centrifugal fan for air purifier and air conditioning,blower for kitchen.

Outline Drawing6. Connection Diagram7. Safety Requirements1. Make sure that the metal casing of the stator connected to the ground before being powered on. 2. Fan needs a few seconds to start after being powered on. To prevent personal injury, do not touch the impellers or rotor when the power is on or in a low speed. 3. Unless they are instructed by the person(s) responsible for their safety, those who are lack of physical, mental or sensory capacities and proper practical experience or expertise cannot use this appliance. Please do not let the children play with this product. 4. If the power cord be damaged, the power cord must be replaced by the manufacturer in order to avoid accident of the proxy service personnel or the equivalent qualification maintenance personnel. 5. Please carefully read this technical specification before using the product.  Model: PF2K140B2AS31.General CharactersRated Voltage230 VACFrequency50/60 HzOperating Voltage198~242 VACCapacitor2μF/500 VACRated Speed1600 RPM / 1200 RPM/ 900 RPMInput Current0.42 A / 0.3 A/ 0.2 AInput Power100 W / 65 W/ 40 WAir Flow325m3 /H / 250 m3 /H/ 175 m3 /HStatic Pressure360 Pa / 320 Pa/ 280 PaAcoustical Noise52 dB(A) / 40 dB(A)/ 32 dB(A)Life Expectance30,000 Hours At nominal supply voltage, full speed room temperature 20ºCDirection of RotationClockwise  seen on rotorInsulation ClassClass FProtection TypeIP44Thermal ProtectionCut off temperature:150-160ºC;replacement  temperature;100-130ºC.2.Mechanical CharactersDimensionSee dimension drawingMaterial of ImpellerPA66Impeller PlateSheet-metal plateMounting PositionAnySurface of RotorCoated in blackBearing SystemBall bearing3.Environmental CharactersOperating Temperature-30ºC to 60ºCStorage Temperature-10ºC to 40ºCOperating Humidity0% to 95% RHStorage Humidity0% to 75% RHDustproof TestTemperature range: 15ºC to 35ºC. 1mm diameter metal wire cannot go through the gap between rotor cup and base.
