The **Freesea Blower Series** includes the **HR series side channel blowers**, known for their high inlet volume flow (up to 2500m³/h) and differential pressure (up to 780mbar). These blowers are designed for reliability, low maintenance, and long-term durability, making them a top choice across various industries. When paired with a frequency converter, performance can be significantly enhanced.
The **2HR series** features motors compatible with both 50Hz and 60Hz voltages, with an IP55 protection rating (insulation class F), allowing for seamless use in Europe, America, and Asia without any modifications or testing.
Key design features include:
- Centrifugal circulation for high pressure and strong airflow
- Air amortize design for reduced noise levels
- Oil-free lubrication for purer air output
- High efficiency and wide range of applications
- Long service life
**Operating Principle:**
The impellers in the 2HR-series machines are mounted directly on the motor shaft, enabling non-contact compression without friction. The bearings are positioned outside the compression chamber, ensuring maximum operational reliability even under high differential pressures.
