A compact direct-drive permanent-magnet VSD screw compressor for correctly sized workshops and light industrial systems where compressed-air demand changes during the working day.
The Tanair TAN-S 5.5 VSD is a 5.5 kW oil-injected rotary screw compressor with permanent-magnet variable-speed control. Its current published output is 19 CFM (0.55 m³/min) at up to 10 bar on a 415V, 50 Hz, three-phase supply.
It is most relevant where compressed-air demand rises and falls through the working day. In those conditions, the variable-speed drive can reduce motor speed when demand falls rather than repeatedly operating at full output or spending long periods unloaded.

The inverter changes motor speed as demand rises and falls, allowing the compressor to reduce output when the site does not need the full 19 CFM.
Where the alternative fixed-speed compressor would spend meaningful time unloaded, demand-matched operation can reduce unnecessary energy use.
That depends on the equipment that can operate at the same time. A 19 CFM compressor should not be described as suitable for a fixed number of workshop bays, spray guns or machines without checking their actual simultaneous consumption.
The TAN-S 5.5 VSD requires a 415V, 50 Hz, three-phase electrical supply. Cable sizing, protective devices, local isolation and the final connection should be selected from the exact compressor data and site installation conditions by suitably competent personnel.
The TAN-S 5.5 VSD is supplied as a standalone compressor, so the receiver and air-treatment system can be selected around the actual application.
The direct-drive arrangement removes belt-related service work, but the compressor remains an oil-injected rotary screw machine and needs planned servicing according to operating hours and manufacturer requirements.
Payback cannot be predicted from compressor kW alone. It depends on the existing system, operating hours, electricity tariff, demand profile, installation cost and measured energy-saving opportunity.
A meaningful ROI comparison needs the current compressor's energy use and operating behaviour, together with your real electricity tariff and proposed installation cost.
The current published output is 19 CFM (0.55 m³/min) at up to 10 bar.
It requires a 415V, 50 Hz, three-phase supply. Cable size, protective devices and isolation should be selected from the exact machine data and site conditions.
Potential savings up to 35% are referenced in the product marketing, but that is not guaranteed. Actual savings depend on the site's load profile, operating hours, pressure, leakage and correct compressor sizing.
It can be, but workshop size or number of bays is not a sizing method. Add the airflow of tools and processes that can operate simultaneously and compare that figure with the compressor's usable output.
No. Direct drive removes belts and belt tensioning, but oil, filters, separator elements, coolers and other routine service items remain.
Rotary screw compressors are commonly used for sustained industrial compressed-air duty, but the exact operating requirements should still be checked against the manufacturer's instructions, site conditions and actual load profile.
Yes. Tanair currently offers a grouped 5.5 kW VSD package with receiver, refrigerated dryer, three-stage filtration and oil-water separation.

Tell us your current compressor, required pressure, operating hours and which tools or machines run together. We can help assess whether the TAN-S 5.5 VSD is correctly sized and what receiver, dryer and filtration may be needed around it.
