Heavy-duty Fixed-speed Single-Stage Screw Air Compressor

At the heart of our Heavy-duty Fixed-speed Single-Stage Screw Air Compressor lies a heavy-duty induction motor designed for direct-drive or high-tension belt-drive configurations. By maintaining a constant RPM, the system ensures a stable volumetric flow rate, critical for processes that cannot tolerate pressure fluctuations.

One-Stage Compression Air-End: Features a low compression ratio and low temperature rise, which translates to reduced air leakage and a 5% energy-saving benefit compared to standard models.

Integrated Shaft Design: Reduces mechanical vibration and alignment issues, ensuring long-term structural integrity even under 100% load.

High-Mass Rotors: Designed to handle thermal expansion without sacrificing tolerance, maintaining efficiency over decades of use.

Technical Performance Matrix (Fixed-Speed Series)

Our Heavy-duty Fixed-speed Single-Stage Screw Air Compressor covers an extensive power spectrum to match any factory scale.

Strategic Advantages

This Heavy-duty Fixed-speed Single-Stage Screw Air Compressor is not just about raw power; it’s about intelligent design that survives harsh conditions.

Large Cooler System with Centrifugal Fan: Utilizing a centrifugal fan for superior cooling effects, the system allows for an ambient operating temperature of up to 52°C.

Large Oil System & Double Separators: Reduces internal pressure loss and avoids oil leakage, contributing an additional 3% in energy savings while ensuring air purity.

Seamless Piping System: The smooth, rust-free piping eliminates pressure drops and ensures a leak-free lifecycle.

Air Routing System: Optimized for “Cold side suction and hot air top discharge,” this configuration prevents heat recirculation, adding 2% to overall efficiency.

Professional FAQ

Q1: When should I choose Fixed-speed over VSD for my Heavy-duty application?

A: Fixed-speed is ideal when your facility runs at >85% load consistently. In these scenarios, the Heavy-duty Fixed-speed Single-Stage Screw Air Compressor is often more efficient and has lower initial capital costs compared to VSD units.

Q2: How does the “One-Stage” design benefit my maintenance schedule?

A: Single-stage compression is mechanically simpler. With fewer moving parts and lower internal temperatures (low temperature rise), there is less thermal stress on seals and bearings, resulting in a longer Mean Time Between Failures (MTBF).

Q3: Can these units handle extreme dusty environments?

A: Yes. Thanks to the “Double Filtering System” and the oversized “Large Oil System,” our compressors are specifically designed to protect internal components from abrasive dust and contaminants.

Q4: Is the 10-inch monitor standard across all models?

A: Yes, we provide the intelligent control system as a standard feature on our heavy-duty series to ensure the operator has full visibility of the system’s “Health Status” at all times.
