FSN Group warranty update (March 2026): 12-month warranty applies to screw compressors when purchased online via an authorised reseller.
The Tanair TAN-S-11VSD is a high-output, energy-saving PM Variable Speed Drive (VSD) screw compressor built for industrial workshops and production environments where air demand changes throughout the day.
It delivers 46 CFM (1.3 m³/min) at 10 Bar from a 415V three-phase supply — with stable pressure, continuous-duty performance, and lower running costs than fixed-speed systems.
The VSD controller automatically ramps motor speed up/down to match real demand, helping reduce wasted energy, minimise cycling and extend component life.
If your operation has peaks and troughs (multiple users, lines switching on/off, spray + tools, shifts), this is the sweet spot where VSD earns its keep.
Best for: multi-user industrial workshops, CNC/automation, spray lines, fabrication/engineering, and continuous shift-based operations.
Key Features & Benefits
11kW (15HP) PM VSD motor – output matches demand
Free air delivery: 1.3 m³/min (46 CFM) @ 10 Bar
Stable system pressure under variable loads
Baosi screw air end for robust, efficient performance
IP55-rated motor for industrial environments
Air-cooled design for straightforward installation and servicing
Power supply: 415V / 50Hz / 3-phase
🔧 What Can This Compressor Run?
With approximately 46 CFM at 8–10 Bar, the TAN-S-11VSD is designed for high-demand, continuous-duty environments where multiple users and processes run together.
✔ Multi-user industrial workshops
✔ CNC machinery and automated production lines
✔ Multiple air stations running simultaneously
✔ Spray booths and finishing lines
✔ Fabrication and engineering facilities
✔ Continuous / shift-based operations
Because it’s VSD, it automatically adjusts output to match demand — reducing energy consumption while keeping pressure stable when your load changes during the day.
Need Help Confirming 46 CFM Is Right?
If you’re unsure whether 46 CFM covers your tools/machinery (or you’re planning to expand), we can calculate your total demand and recommend the right setup — including dryers, filtration and pipework.
Warranty: Two years (subject to manufacturer’s T&Cs).
What’s Included
Complete PM VSD screw air compressor unit
Integrated control system

Long service life and consistent airflow delivery
Efficient design for continuous operation
Proven reliability in industrial duty cycles
Fast ROI & Lower Running Costs
Energy is typically the biggest lifetime cost of compressed air. Because the TAN-S-11VSD adjusts output to true demand, it reduces wasted electricity, lowers running costs and helps extend service intervals.

How quickly does a VSD compressor pay for itself?
Many users see payback within a few years due to reduced electricity usage and lower wear from reduced cycling.
Is this suitable for continuous use?
Yes — screw compressors are designed for continuous duty, and VSD improves efficiency when demand fluctuates.

Hi Sam, Thank you for taking time to review our company. I'm so glad we were able to help! Kind regards Team CAS
I can't recommend CAS UK enough. We had a Clarke for a couple of years that we abused running it 12 hours a day. We found CAS UK when it needed a repair, and we were very impressed with how quickly they responded and came out to repair and service the machine.
Our business started to expand and we needed a large compressor with a proper airlines feeding our machines and work stations. The guys from CAS supplied the new compressor and worked flat out getting the machine and pipe working in. They're a brilliant group of lads with a great work ethic and really easy to communicate with.
We'll 100% continue to use and recommend them.

Took in what I believed to be a beyond repair compressor. Received back, an as new machine, all physical damage repaired and connector fittings renewed to latest standard. Compressor delivered to my premises in what was a great service by Compressed Air Systems UK. Thanks for a great experience
Me and my company have been using compressed air systems for around 10 years! Very professional always great advisor for the best machine for what we need, friendly office staff and most of all the knowledge from them is second to none. Would recommend to anyone that needs advise or want to buy the right machine for them. Plus the backup you get is the best.
What a refreshing team to have as competent suppliers for our leads and compressed air; not once have they given us poor service. They've saved our business; A Gilligan (Coatings) Ltd thousands of pounds per year with new high tech and efficient equipment. Their advice and service supplied over the last 15 year period has been extremely valuable, we would never consider another company for our compressed air services
Had a new compressor fitted a few months ago. Perfect service and amazing aftercare. I was advised well and even advised towards a better value option saving us a chunk of money. Top quality honest service all round...... Thanks again.
