Slim Installation Height and High Air Flow Rate with lowest Noise

Solar Heating DC 30mm Centrifugal Cooling Fan for Air Curtain

PBM tangential blowers combine 30~80mm diameter cross flow impeller with one single piece length maximum to 65mm, with AC and DC power supply EC green technology motor, with aluminum die cast fan frame, with anti-vibration rubber damping pad system, with ball bearing and sleeve bearing, maximum entire tangential fan length goes up to 1190mm at single, double and triple sections harmoniously connected together makes it possible to achieve a very high airflow throughput ratio with extremely low wind noise with quiet three-core sin-wave integrated commutation electronics motor controller circuit and low air flow velocity. Cross flow blowers are available for home indoor stove, fireplace, oven, wood burner underfloor convectors, air doors, air curtains, air conditioners and heaters' cooling and ventilation at extremely shallow, flat design to satisfy home appliances' nice outlooking and slim features that market requirements and consumer calling for. Low noise with high air flow rates and low back pressures, compact slim design with anti-vibration rubber mechanical soft connection system, moisture proof and water proof versions are available for entire range tangential blowers with integrated and intelligence EC technology motor with PWM signal and 0~10V analog voltage to adjust power, and ErP2015 (Energy-related Products) directive conformity.

Impeller Sizes: from 30mm to 80mm diameter;Sound Level: from 32dBA to maximum 48dBA according different rotation speed;Airflow: maximum to 600CMH, Cubic Meter per Hour, equal to approx. 353CFM , Cubic Feet per Minute;Air Pressure: Maxim to 80Pa, equal to 8.16mm H2O and to 0.32 inches H2O;Power: Maximum motor input power goes to 100W motor diameter 80mm.

Electrical Protection:

3-1Locked-rotor ProtectionOver-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.
3-2Maximum Current under Locked RotorA, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running current reoccurring and for 16~20% of restarting cycle period. B, If he CL function is used this restarting inrush current is about the same as the normal running current.
3-3Reverse Polarity ProtectionNo damage if the positive and negative leads are reversed under maximum operation voltage conditions.
3-4Over Voltage ProtectionThe circuit will be shut down automatically when input voltage over 30VDC. And re-started when Voltage down to 30VDC below.
3-5Soft StartIn 5 seconds after power on and speed control voltage gets to 1.5V.
