The Ultimate Guide to the Tanair TAN-S 11 VSD: 46 CFM Premium Variable Speed Drive Compressor
In workshops with fluctuating air demand, the Tanair TAN-S 11 VSD delivers reliable 46 CFM at 10 bar while automatically matching output to real-time needs, achieving significant energy savings of up to 35% compared with fixed-speed compressors.
Key areas covered in this guide
Whether you manage an automotive workshop, engineering facility, or light manufacturing site with varying air demand, this guide details how the TAN-S 11 VSD can reduce energy costs and deliver consistent performance.
What Makes the Tanair TAN-S 11 VSD Stand Out
Are you tired of high electricity bills and inconsistent pressure? The premium 11 kW VSD air compressor from Tanair changes that by automatically matching output to real-time demand, delivering reliable 46 CFM at 10 bar while cutting energy use dramatically.
This air-cooled, direct-drive rotary screw compressor combines advanced permanent magnet variable speed drive technology with robust engineering, making it an excellent choice for UK workshops and light industrial settings with fluctuating air demand.
Variable speed drive technology adjusts motor speed precisely to demand, eliminating the energy waste common in fixed-speed compressors that run at full power or idle unnecessarily.
How Variable Speed Drive Technology Delivers Superior Efficiency
Variable speed drive (VSD) compressors use an inverter to adjust motor speed in real time according to air demand. Unlike fixed-speed models that run at full power or idle, a VSD unit slows down when demand drops and accelerates only when required.
This intelligent control typically achieves energy savings of 20–35%, and often more, depending on usage patterns. The Tanair TAN-S 11 VSD features a premium permanent magnet (PM) VSD motor with IP55 protection, enhancing efficiency and safeguarding against dust and moisture in workshop environments.

Direct Drive Design: Low Maintenance and Higher Efficiency
The Tanair TAN-S 11 VSD features a direct drive airend that eliminates belts and associated components, avoiding slip, tension adjustments, and premature wear.
The air-cooled design simplifies installation with no need for water connections, making the unit suitable for a wide range of workshop environments.
Energy Savings and Return on Investment
VSD technology excels in facilities where demand varies between 40% and 80% of maximum capacity. In such conditions, the Tanair TAN-S 11 VSD can deliver substantial annual savings on electricity bills compared with fixed-speed equivalents.
The premium pricing of £3,750.00 ex VAT is often recovered quickly through reduced energy consumption, softer starts that minimise electrical surges, and extended component life due to fewer load/unload cycles.
