Fixed-Speed Screw Compressors for Industrial Use
Fixed-Speed Screw Compressors for Industrial Use
Reliable. Affordable. Engineered for African Conditions.
At Super-Air, we do more than build compressors, we engineer them to thrive in Africa’s toughest environments. For 18 years, our Fixed-speed Screw Compressors have been the backbone of industries across the continent, proving themselves day in and day out, even in the harshest conditions.
Why Choose a Fixed Speed Screw Air Compressor?
Designed specifically for African Conditions
From intense heat to pervasive dust, our compressors are purpose-built for resilience and longevity.
Decades of Know-How
Collectively, our team brings over 48 years of expertise in manufacturing, maintaining, servicing, and repairing all types of compressors. This deep institutional knowledge ensures every Supa-Air unit delivers peak performance.
Motors Engineered for Screw Compressor Duty
We only use motors designed for compressor use, never standard motors. With a minimum service factor of 1.2, they’re built to exceed expectations and endure the toughest workloads.
Minimal Downtime, Maximum Support
Thanks to our extensive spare parts stock, we’re ready to serve customers countrywide, minimizing downtime and keeping your operations running smoothly.
Oversized Air Ends for Cool, Efficient Operation
Our air ends are intentionally oversized and run at slower RPMs, no gears needed. This approach creates cooler air, reduces wear, and extends the lifespan of your compressor.
