TEH TAC50L 50L Oil-Free Air Compressor — Twin Motor 4HP — 8 Bar — Workshop & Trade

The TEH TAC50L is a professional-grade 50-litre oil-free air compressor powered by twin 1500W motors delivering a combined 4HP (3000W) of output — putting it in a completely different performance class from single-motor compressors of the same tank size. With a real-world FAD of 240 L/min (8.5 CFM) at 6 Bar and 200 L/min (7.0 CFM) at 8 Bar (116 PSI), the TAC50L delivers the sustained, consistent airflow that professional trade and workshop applications demand.

Each motor uses 100% pure copper winding and corrosion-resistant copper valves, providing significantly greater thermal stability than aluminium-wound alternatives. This allows the TAC50L to run harder, longer, and cooler — maintaining consistent output throughout a full working day. The independent dual-switch architecture allows each motor to be operated separately, extending service life by managing load according to the tool in use. The low noise design operates at just 80 dB — noticeably quieter than traditional oiled compressors of equivalent power.

The 100% oil-free design means zero maintenance, no oil contamination in the airline, and instant start every time with no warm-up required. Whether running a full-size HVLP spray gun, framing nailers, or multiple tools simultaneously, the TAC50L delivers without hesitation. Backed by a 1 year warranty and free UK mainland delivery, the TAC50L is the professional's choice for trade and workshop use.

Performance and Flow Rate Guide

The TAC50L delivers consistent airflow from 500 L/min at 0 Bar down to 200 L/min at the maximum rated pressure of 8 Bar (116 PSI). All figures in the table below are taken directly from the factory-measured performance chart. The 6 Bar and 8 Bar values are confirmed FAD figures. Always match your tool requirements against FAD — not max displacement — when assessing suitability.

Flow curve data is taken directly from the factory performance chart. The 6 Bar figure of 240 L/min and the 8 Bar figure of 200 L/min are confirmed factory FAD values. FAD (Free Air Delivery) represents actual usable airflow at the outlet at the stated pressure.

Tool Compatibility and Simultaneous Use Guide

The TAC50L is rated for up to 3 simultaneous tools at full working pressure. Use the guide below to calculate your workshop airflow requirements.

Continuous Full Support

• Full-size HVLP spray guns (~7 CFM): Fully supported for continuous bodyshop prep, primer application, and single-panel spray work
• Framing nailers (~2-3 CFM each): Run 2-3 simultaneously — continuous support for framing, structural fastening, and roofing work
• DA and orbital sanders (~4-6 CFM): Continuous sanding for workshop prep and finishing work
• Blow guns and air dusters (~3 CFM): Continuous operation — no restriction
• Tyre inflation and light trade tools: Continuous operation — well within rated capacity
• Air ratchets and light impact tools (~3-4 CFM): Continuous use for automotive and mechanical work

Supported Simultaneous Combinations

• Framing nailer and HVLP spray gun together: Combined ~9-10 CFM — within rated capacity at 8 Bar FAD
• 2 framing nailers and a blow gun: Combined ~8-9 CFM — supported at rated working pressure
• HVLP spray gun and air ratchet: Combined ~10-11 CFM — supported at rated capacity

Not Recommended for Continuous Use

• Multiple full-size orbital sanders running simultaneously: Each sander requires 10-12 CFM — step up to TAC100L or TAC130L for multi-sander workstations
• Industrial grinders at full sustained output: For sustained heavy grinding, the TAC100L or TAC130L provides the required sustained FAD

Perfect For

• Professional trade workshops and garages
• Full-size HVLP spray painting for bodyshop prep and panel work
• Framing, finish, and brad nailers across multiple workstations
• DA and orbital sanding for workshop surface preparation
• Automotive mechanical work — air ratchets and impact tools
• Woodworking workshops requiring sustained multi-tool support
• Any professional trade application requiring up to 3 tools simultaneously
• Situations where clean, oil-free air is essential for quality output

Key Features

• Twin Motor 4HP Configuration: Two independent 1500W motors with individual switching for load management and extended service life
• 100% Pure Copper Motor and Valves: 2x the thermal stability of aluminium alternatives — runs cooler, lasts longer, maintains output under heavy load
• 200 L/min FAD at 8 Bar: 7.0 CFM confirmed free air delivery at full working pressure — factory-verified
• Dual Pressure Gauges: Simultaneous monitoring of tank and working output pressure for precise tool control
• Low Noise 80 dB: Significantly quieter than traditional oiled compressors of equivalent power
• 100% Oil-Free: Zero maintenance, no oil top-ups, no contamination, instant start with no warm-up
• Independent Dual-Switch Architecture: Operate one or both motors according to tool demand — protects motors and extends compressor service life
• 50-Litre Steel Tank: Large tank capacity for sustained airflow and reduced cycling frequency
• Up to 3 Simultaneous Tools: Professional multi-tool capability in a 50L footprint
• 1 Year Warranty: Full manufacturer warranty covering parts and motors

UK Workshop Installation Guide

Power Requirement

NOTE: The TAC50L operates on 230V but draws up to 3000W (4HP) across both motors. A 16A supply is recommended for reliable dual-motor operation. Standard 13A sockets may trip under the full startup load of both motors simultaneously. If using a 13A socket, operate one motor at a time only.

Daily Maintenance

Water condensate collects in the 50-litre tank during use. Open the drain valve at the base of the tank daily to release condensation and prevent internal corrosion. This takes under 60 seconds and is essential for long-term tank performance.

Independent Motor Control

Use the independent dual-switch panel to manage motor load according to the tool in use. For lower-demand tools, run one motor only to extend service life. For high-demand sustained applications, run both motors simultaneously.

Warranty and Support

WARRANTY: The TEH TAC50L is covered by a 1 Year Manufacturer Warranty from the date of purchase, covering manufacturing defects in parts and motors under normal operating conditions. Warranty is valid for UK purchases through TEH Tools UK. Daily tank drainage is required to maintain warranty validity.
