compact size cooling blower

14kPa  30CFM 2" inline compact size cooling blower Suitable for air cushion machine/fuel cell/cooling machine

Products Details

This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction. Filter onto the inlet to protect the blower from dust and water. Keep the environmental temperature as low as possible to make the blower life time longer.Certification: ce, RoHS Warranty: 1 Year After-sales Service Provided: Online support Life time(MTTF): >20,000hours (under 25 degree C) Weight: 1.5 Kgs Housing material:PC Size:140*120MM Motor type:Three Phase DC Brushless Motor Controller: external Static pressure: 15kPaBrand name: Wonsmart High pressure with dc brushless motor Blower type: Centrifugal fan Voltage: 48 vdc Bearing: NMB ball bearing Applicable Industries: Manufacturing Plant Electric Current Type: DC Blade Material: plastic Mounting: Ceiling Fan Place of Origin:Zhejiang, ChinaWS140120S-48-130-X300 blower can reach maximum 88m3/h airflow at 0 kpa pressure and maximum 15kpa static pressure.It has maximum output air power when this blower run at 7kPa resistance if we set 100% PWM, It has maximum efficiency when this blower run at 7kPa resistance if we set 100% PWM.Other load point performance refer to below P-Q curve:(1) WS140120S-48-130-X300 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 10,000hours at 20degree C environmental temperature. (2) This blower needs no maintence; (3) This blower drived by a brushless motor controller have many different control functions such as speed regulation,speed pulse output,fast acceleration,brake etc.it can be controlled by intelligent machine and equipment easily. (4) Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.This blower can be widely used onto air purify,air bed,cooling,vacuum machine.Q: Do you also sell controller board for this blower fan? A: Yes, we can supply adapted controller board for this blower fan. Q: How to change impeller speed if we use your controller board? A: You can use 0~5v or PWM to change speed. Our standard controller board is also with a potentiometer to change speed conveniently. Q: What is the MTTF of this centrifugal air blower?
