Tanair Variable Speed Air Compressors
Compare 5.5, 7.5, 11 and 22 kW direct-drive permanent magnet VSD compressors for workshop and industrial applications.
Choose the Right Tanair VSD Compressor
The correct model depends on required free air delivery, working pressure, daily running hours, demand variation and future growth. Start with the airflow your site genuinely needs, rather than choosing by motor kW alone.
5.5 kW – 19 CFM
For lighter workshop demand, smaller production areas and sites replacing a compact industrial compressor.
7.5 kW – 32 CFM
For growing workshops and multi-user compressed air systems with moderate variable demand.
11 kW – 46 CFM
For engineering, manufacturing and production sites requiring a stronger continuous air supply.
22 kW – 112 CFM
For larger industrial systems, higher airflow demand and multiple tools or processes operating together.

How to Choose the Right Tanair VSD Compressor
When does a VSD compressor make sense?
VSD compressors are strongest where demand changes throughout the day. The compressor can reduce motor speed when less air is required instead of repeatedly running fully loaded and then off-load.
Is VSD always better than fixed speed?
No. A correctly sized fixed-speed compressor may still be suitable where demand is steady and the machine operates loaded for long periods. The best choice depends on the site's actual demand profile.
How should I calculate the required CFM?
Add the free air requirements of tools and processes that may operate at the same time, then allow for leakage and sensible future growth. Do not choose from motor kW or receiver capacity alone.
What working pressure should I select?
Select the lowest pressure that reliably supports the application after losses through dryers, filters, pipework and regulators. Unnecessary pressure increases energy use.
Does a larger receiver increase CFM?
No. A receiver stores compressed air and helps manage short demand peaks, but it does not increase the compressor's continuous delivered airflow.
What installation checks are required?
Confirm electrical supply, ventilation, service clearance, receiver capacity, dryer and filtration requirements, condensate management and pipework sizing.
Tanair VSD Model Guidance
5.5kW and 7.5kW models are commonly suited to smaller workshops, garages, spray booths and light industrial environments where compressed air demand varies during the day.
11kW and 22kW models are often better suited to larger workshop systems, production environments, engineering sites and manufacturing operations with higher airflow requirements or multiple users.
5.5kW
Compact VSD solution for lighter workshop and small industrial applications.
7.5kW
Versatile option for growing workshops and multi-user air demand.
11kW
Strong industrial choice for production and engineering environments.
22kW
Higher airflow for larger industrial systems and demanding sites.
Typical Applications
VSD air compressors are commonly used where efficient compressed air is required but demand is not constant from hour to hour.

What is a VSD air compressor?
A Variable Speed Drive air compressor adjusts motor speed to match real-time air demand, helping reduce electricity usage and maintain more stable system pressure.
How much energy can a VSD compressor save?
Savings depend on your usage profile, but in variable demand environments a VSD compressor can significantly reduce wasted energy compared with a fixed-speed system.
Are VSD compressors worth it for workshops?
Yes. Where compressed air demand rises and falls during the day, a VSD system can help improve efficiency and reduce running costs.
Can you help choose the right compressor size?
Yes. We can help assess your airflow, pressure and duty cycle requirements to recommend the right compressor for your application.
