**Freesea Blower Series**
The HR series of side channel blowers are known for their high inlet volume flow, reaching up to 2500m³/h, and differential pressure up to 780mbar. These blowers are reliable, low-maintenance, and durable, making them a top choice for various industrial applications. When paired with a frequency converter, their performance can be significantly enhanced. The 2HR series features motors that support both 50Hz and 60Hz voltage ranges, with an IP55 protection class (insulation class F), allowing them to be used in Europe, America, and Asia without any modifications or testing.
With a centrifugal circulation design, these blowers offer high pressure, large airflow, and a quiet operation due to the air amortize design. They also feature an oil-free lubrication system, ensuring purer air, higher efficiency, and longer service life. The bearings are placed outside the compression chamber, ensuring maximum operational reliability even under high differential pressures.
**Key Features:**
- Oil-free operation
- High-pressure capability
- Low noise level
- Energy-efficient design
- Long-lasting performance
- Wide range of applications
**Operating Principle:**
The impellers in the 2HR-series machines are mounted directly on the motor shaft, enabling non-contact compression without friction. This design ensures smooth and efficient operation while minimizing wear and tear.
