Tanair TAN-S-5.5VSD (415V) | 19 CFM Variable Speed Screw Air Compressor
SKU: TAN-S-5.5VSD
Brand: Tanair Compressors
Energy-Efficient 5.5kW Variable Speed Screw Air Compressor
The Tanair TAN-S-5.5VSD (415V) is a compact, energy-efficient variable speed screw air compressor delivering 19 CFM (0.55 m³/min) at 10 bar, ideal for workshops and light industrial applications with fluctuating air demand.
Powered by Permanent Magnet Variable Speed Drive (PM VSD) technology, the compressor continuously adjusts motor speed between 40% and 100% capacity, producing only the air required. This intelligent control significantly reduces wasted energy while maintaining stable system pressure—resulting in energy savings of up to 35% compared to fixed-speed compressors.
Built with a Baosi screw air end and a robust IP55-rated motor, the TAN-S-5.5VSD offers reliable, low-noise operation and long service life in demanding UK working environments.

Frequently Asked Questions
How much energy can a VSD air compressor save?
A variable speed drive (VSD) air compressor can reduce energy consumption by up to 35% compared to a fixed-speed compressor. Actual savings depend on operating hours, pressure requirements, and air demand variation.
How quickly does a VSD screw compressor pay for itself?
Many businesses see a fast return on investment, often within a few years or less. Because energy is the largest lifetime cost, reducing electricity usage delivers measurable financial benefits.
Is a VSD compressor worth it for small workshops?
Yes. Workshops with fluctuating air demand benefit greatly from VSD technology, as it prevents energy waste during idle or low-load periods.
How do I calculate my compressor energy savings?
You can use Tanair’s ROI and energy-savings calculator to compare your existing compressor with a PM VSD model by entering your operating hours and usage profile.
Are VSD compressors suitable for continuous industrial use?
Yes. PM VSD screw compressors are ideal for continuous and variable demand applications, offering stable pressure, reduced wear, and improved efficiency.
