BS-DH Oil-free Screw Blower Package

The Gardner Denver BS High-Pressure Oil-Free Screw Blower delivers clean, food-grade compressed air for critical applications such as fermentation and pneumatic conveying. Designed for the food and beverage, pharmaceutical, and related industries, it provides pressures up to 2.5 bar(g), flow rates up to 9,300 m³/h, and adjustable capacity from 30% to 100% to meet varying process demands.

High-Efficiency Oil-Free Screw Air End

Advanced oil-free screw technology and a highly integrated design combine key components into a compact, efficient system. This optimized structure delivers reliable performance, energy efficiency, and reduced installation space requirements.

 

Energy-Saving Automatic Intake Valve Control

The intelligent intake valve automatically adjusts air production based on demand. When air consumption drops, the valve unloads and closes to minimize energy waste, prevent pressure build-up, and improve system reliability.

 

Intelligent Controller with IoT Connectivity

A smart control system continuously monitors blower performance in real time. IoT capabilities enable remote monitoring, fault alerts, cloud-based data storage, and predictive maintenance for maximum operational efficiency.

 

Low-Noise Operation

A patented silencer design provides superior noise reduction, especially for mid- and low-frequency sounds. Compared with conventional mufflers, it delivers longer-lasting performance, cleaner airflow, and a quieter working environment.

 

Water-Cooled Lubricating Oil Cooler

The shell-and-tube water cooler features durable stainless steel tubes for excellent heat resistance and corrosion protection. It performs reliably even with hard cooling water and demanding industrial conditions.

 

Compact Air-Cooled Oil Cooler

Featuring aluminum plate-fin construction, the air-cooled option offers efficient heat dissipation in a compact footprint. Its simple design ensures easy installation, low maintenance, and dependable cooling performance.

 

Reliable and Energy-Efficient Design

Engineered for industrial applications, the blower combines oil-free technology, intelligent controls, low-noise operation, and efficient cooling. The result is reliable performance, lower operating costs, and long service life.
