Low Pressure Fan & Blowers

forward-curved-centrifugal_fan_blower
High air volume centrifugal fan with forward curved impeller.

Low and intermediate pressure fan type blowers

Fans and blowers with low pressure capacities include centrifugal fans, axial fans, extractor (extraction) fans and portable fans

Multi-vane, low noise blowers deliver high volumes at moderate pressures. A centrifugal blower is used in industrial applications such as for manufacture industries, underground facilities for cooling, temperature control and ventilation, the paper and paint industry etc.

Note 10,000 Pa = 100mbar, 0.1Bar, 1.45PSI

Inflatable blowers

plastic housing blower

For some applications, low pressure, medium volume delivery is needed.
An example is blowers for inflatable jumping castles, advertisements, slides, pools, boats, advertising balloons etc.
Other applications would be for example aerating compost heaps.

Typical Pressure delivery for jumping castle blowers

Plastic blower specificaions

Jumping castle blowers are low pressure, high volume blowers. 2KPa is only 20 millibars or 20cm of water as a maximum air deliver pressure. Air flow rates are however high at around 20m3/h for most blowers.
