Constant Pressure Fixed-speed Single-Stage Screw Air Compressor

Critical Engineering for Pressure Stability

The Constant Pressure Fixed-speed Single-Stage Screw Air Compressor is designed for facilities where even a 0.1 bar fluctuation can compromise product quality. Our engineering focuses on the “One-Stage” advantage:

Precision Air-End: Features a low compression ratio that reduces internal thermal rise and air leakage, yielding a direct 5% energy-saving benefit.

Induction Motor Power: Optimized for fixed-speed operation to provide a “Steady-State” air supply that is far more durable than standard light-duty alternatives.

Integrated Drive-Train: The seamless shaft design eliminates alignment friction, ensuring that mechanical energy is converted directly into stable air pressure.

Performance Data & Model Selection

Our China manufacturer technical team has optimized these models to deliver high Free Air Delivery (FAD) across a wide range of power ratings.

Strategic Advantages of the Fixed-Speed Architecture

While many suppliers push variable speed for all applications, as an expert manufacturer, we know that for a constant 24/7 baseload, our Constant Pressure Fixed-speed Single-Stage Screw Air Compressor offers superior durability:

Advanced Cooling Efficiency: Equipped with a centrifugal fan system that creates a high-velocity cooling effect, allowing the unit to maintain constant pressure even in ambient temperatures of 52°C.

Enhanced Oil Management: Features a large oil system combined with double oil separators to reduce internal pressure loss, saving 3% in energy while preventing oil carryover.

Double Filtration Protection: Protects the air end from abrasive particulates, ensuring a significantly longer service life for both the lubricants and the rotors.

Optimized Air Routing: Our “Cold side suction and hot air top discharge” design adds a 2% energy-saving margin by preventing heat recirculation.

Industrial-Grade Intelligence & Control

To ensure ease of use for our global partners, every unit includes:

Intelligent Control System: A 10-inch HMI monitor provides full transparency into all operating data, ensuring trouble-free management.

Seamless Piping: Our smooth, rust-free internal piping prevents the pressure loss common in systems using flexible hoses.

Heavy-Duty Filtration: The high-capacity intake filter ensures the air cleanliness required for sensitive downstream equipment.

Expert FAQ for Global Sourcing

Q1: Why is “Constant Pressure” critical for fixed-speed machines?

A: In fixed-speed units, maintaining constant pressure prevents unnecessary “load/unload” cycles, which reduces mechanical wear on the intake valve and contactors, ultimately lowering your total cost of ownership.

Q2: How does your China factory ensure the quality of such heavy units?

A: Every Constant Pressure Fixed-speed Single-Stage Screw Air Compressor undergoes a full-load performance test to ISO 1217 Annex C standards. We verify FAD, pressure stability, and thermal equilibrium before shipping.

Q3: Is this compressor suitable for high-dust environments?

A: Absolutely. With our “Double Filtering System” and centrifugal cooling fan, these units are specifically built to operate reliably in mining, cement, and textile industries.
