OWB8040-12V Low Power Centrifugal Fan For Safety Mask Fan Sleep Ventilator Environment Detector
Note:This blower requires a driver to function properly.
This fan OWB8040 is based on the modification of the air duct and the air inlet and outlet area made on the OWB7040. At present, the fan has reached the original intention of low noise, low power consumption, large air volume and small wind pressure. It is used in portable air supply equipment powered by batteries, chemical protective clothing, inflatable clothing toys, CPAP sleep ventilators and other medical auxiliary equipment.
Product Usage:
Sine wave drive three-phase brushless motor, suitable for --- air cushion machine, fuel cell, ventilator air supply, modified car seat cushion air supply, electric heat is sent air, high-grade soldering station smoke, sanding.
Product advantages:
1. High pressure (full pressure 6.5KPA)
2. Large air volume (380 liters / minute)
3. Low noise (42Db (A) 1KPa distance 1M far)
4. Long life(run 4 hours, stop 30 minutes life up to 25000 hours)
5. The motor movement is designed with a hollow cup structure
6. High efficiency, high speed, high stability
7. This brushless fan has stable start, small size, low noise, low temperature rise, long service life, high efficiency, accurate accuracy, energy saving and environmentally friendly materials.

Attentions:
1: Do not working under the max air pressure, the air flow is too small at max air pressure, and it's not safe for using.
2: Add a filter attach to the intake makes the blower bearing longer service life.
3: The correct rotation direction is CCW
4: Do not use the blower in High temperature ,high humidity, high magnetic fields
5: Please use suitable power supply for the blower.
