DOUBLE STAGE PISTON COMPRESSORS

High-Performance Air Compression for Diverse Applications

The Double Stage Piston Compressors are a testament to engineering excellence, crafted to deliver reliable and efficient compressed air solutions. Designed with superior materials and innovative technology, these compressors are built to handle demanding industrial tasks, ensuring optimal performance, long life, and minimal maintenance. With a cast iron crankcase and cylinders, corrosion-resistant stainless steel valves, and precision cooling mechanisms, these compressors stand as an ideal solution for industries ranging from manufacturing to automotive and more. Whether you’re managing a small workshop or a large-scale operation, the Double Stage Piston Compressors offer unmatched durability, efficiency, and versatility.

Key Features of DOUBLE STAGE PISTON COMPRESSORS

  1. Durable Build and Materials
    • The crankcase and cylinders are constructed from Gray cast EN GJL250, ensuring superior strength and long service life.
    • The crankshaft is crafted from solid EN-GJS 500-7 material, offering exceptional resilience under heavy loads.
    • Low-speed pistons reduce wear and ensure smoother operation.
  2. Stainless Steel Valves
    • Corrosion and heat-resistant stainless steel valves ensure consistent performance, even under extreme conditions.
  3. Air-Cooled Efficiency
    • Equipped with intermediate and after-coolers, the compressors use a flywheel propeller to create effective air cooling, maintaining optimal performance even in high-temperature environments.
  4. Dual-Stage Compression
    • Single-stage models are rated for 8 bar pressure, while double-stage variants achieve up to 15 bar, making them suitable for higher-pressure applications. High-pressure models support ranges between 25-50 bar, catering to specialized needs.
  5. V-Belt Drive System
    • The compressors utilize a V-belt and pulley mechanism for efficient power transmission. This design minimizes energy loss while ensuring reliable operation.
  6. Flexible Motor Options
    • Models up to 4 kW feature single-phase motors, while more powerful variants utilize F-insulated, IP55-protected, IE2 asynchronous motors for maximum efficiency and durability.
  7. Precision Lubrication System
    • The compressors feature a whipping lubrication system integrated into the crankshaft design, ensuring smooth and consistent operation.
  8. Easy Maintenance Features
    • A sight glass integrated into the compressor head allows users to monitor oil conditions effortlessly.
    • A mini ball valve facilitates easy oil drainage.
    • The air filter element, housed in a plastic filter bowl, is simple to replace, reducing downtime.
  9. Safety and Compliance
    • The belt-pulley system is enclosed, meeting CE safety standards.
    • A pressure switch regulates operation, while a safety valve protects against overpressure.
  10. Smart Startup and Control
    • Compressors up to 4 kW feature direct startup via a motor protection switch. Models with 5.5 kW or higher use a star-delta control panel for smooth operation.
    • A one-way check valve prevents air backflow into the compressor, ensuring system safety.
  11. Integrated Air Tanks
    • Air tanks are manufactured in-house to meet 2009/105/EC directives, guaranteeing compliance and reliability.
    • Tanks are equipped with ball valves for easy condensate drainage and outlet air control.
