/HDBS-40-150 30 kW Oil-Free Screw Blower

HDBS-40-150 30 kW Oil-Free Screw Blower

The HDBS-40-150 is a 30 kW oil-free screw blower designed for industrial low-pressure air supply. Applications include wastewater aeration and pneumatic conveying. Its airflow range is 4.0–7.0 m³/min, with a pressure range of 80–150 kPa. Internal screw compression, an enclosed cabinet and forced-circulation lubrication and cooling are combined in one package. The operating point should be selected against the process airflow and backpressure requirements, with DN150 inlet and outlet flanges provided for pipeline connection.

HDBS-40-150 30 kW Oil-Free Screw Blower

The HDBS-40-150 is a 30 kW oil-free screw blower designed for industrial low-pressure air supply. Applications include wastewater aeration and pneumatic conveying. Its airflow range is 4.0–7.0 m³/min, with a pressure range of 80–150 kPa. Internal screw compression, an enclosed cabinet and forced-circulation lubrication and cooling are combined in one package. The operating point should be selected against the process airflow and backpressure requirements, with DN150 inlet and outlet flanges provided for pipeline connection.



1. Oil-Free Compression. The screw compression process operates without oil injection into the compression chamber, helping limit contamination of the supplied air by blower lubricant.

2. Capacity for Low-Pressure Processes. A 30 kW power rating, 4.0–7.0 m³/min airflow range and 80–150 kPa pressure range provide clear starting specifications for selecting a blower against process demand.

3. Internal Screw Compression. Air is compressed inside the screw airend before discharge. This internal compression mechanism supports efficient pressure generation for industrial processes that require low-pressure air.

4. Enclosed Acoustic Cabinet. The integrated cabinet contains the blower assembly and provides sound insulation, helping control operating noise while simplifying the arrangement of equipment at the installation site.

5. Forced Lubrication and Cooling. A forced-circulation lubrication and cooling system supports the mechanical assembly by maintaining lubricant circulation and removing heat during operation, helping sustain stable blower performance.

6. Planned Access and Pipeline Connections. A layout designed for operation and maintenance makes routine service easier to organize. DN150 inlet and outlet flanges give installers defined connection sizes for process piping.
