What Is an Oil-Free Low Pressure Blower?

An oil-free low pressure blower is an industrial air supply device designed to deliver large airflow at relatively low pressure, typically between 10 kPa and 100 kPa.

Unlike compressors that focus on generating high pressure, blowers prioritize high air volume with stable pressure, making them ideal for applications such as:

Biological
aeration

Pneumatic
conveying

Fermentation air
supply

Industrial oxidation
processes

Frequently Asked Questions

What pressure range is considered low pressure for blowers?

Low pressure blowers typically operate between 10 kPa and 100 kPa (0.1–1 bar) and are designed to deliver large airflow volumes.

What is the difference between a blower and a compressor?

Blowers deliver large airflow at low pressure, while compressors generate high pressure with lower airflow.

Which blower is best for wastewater treatment aeration?

Screw blowers and magnetic bearing turbo blowers are commonly used because they provide high efficiency and stable airflow.

Are these blowers completely oil-free?

Yes. Our systems deliver 100% oil-free air and meet ISO 8573-1 Class 0 standards.
