Unveiled for the first time at HIGH END Vienna 2026, the new TechDAS Air Force 20 immediately captured the attention of analogue enthusiasts and industry professionals alike. Showcased as a working prototype, the Air Force 20 received widespread praise for its sonic performance, advanced engineering, and refined industrial design, further reinforcing TechDAS’ reputation as one of the world’s leading turntable manufacturers.
Building upon the technologies that have made the Air Force Series a reference in high-end analogue playback, the Air Force 20 introduces a number of significant developments aimed at extracting even more information from the record groove while reducing unwanted mechanical influences.
Vacuum Hold-Down and Air Float Technology
At the heart of the Air Force 20 are TechDAS’ renowned Air Vacuum and Air Float systems.
The vacuum hold-down system securely draws the record against the platter surface, flattening warps and creating a rigid interface between the vinyl and platter. This dramatically improves stylus tracking accuracy and reduces unwanted resonances that can obscure fine musical detail.
Complementing this is the Air Float system, where the platter rotates while floating on an ultra-thin cushion of air measuring just 10 microns. By virtually eliminating mechanical contact within the bearing assembly, the system achieves an exceptionally low noise floor, allowing music to emerge from an extraordinarily quiet background.
The Air Force 20 utilises an A7075 Extra Super Duralumin main chassis, the same ultra-high-strength aluminium alloy employed in the flagship Air Force One. This material provides exceptional rigidity while forming the foundation of the turntable’s precision-engineered structure.
Supporting sections are manufactured from A5056 aluminium alloy, selected for its superior vibration absorption characteristics. Beneath the main chassis sits a substantial 60kg stainless steel base frame, creating a highly stable platform that resists external vibration and mechanical interference. Together with TechDAS’ carefully engineered isolation strategy, the result is remarkable stability during operation.
Flywheel-Equipped Air-Bearing Drive System
A major innovation within the Air Force 20 is its flywheel-equipped air-bearing drive motor.
Driven by powerful 130-watt amplifiers, the flywheel itself floats on an air bearing, ensuring exceptionally smooth operation. A non-contact magnetic coupling isolates the flywheel from the motor, preventing vibration from being transferred through the drive system. This sophisticated approach allows the platter to rotate with exceptional speed stability while maintaining extremely low levels of mechanical noise.
Redesigned Hybrid Isolation
Drawing inspiration from the acclaimed Air Force Two, the Air Force 20 features a newly engineered Monotube Oil-Damped Spring Suspension. The system combines mechanical spring isolation with fluid damping technology. Isolation springs are encapsulated within damping fluid and controlled by a precision free-piston arrangement, allowing unwanted spring oscillations to be rapidly absorbed and controlled.
The result is highly effective isolation from environmental vibration while maintaining excellent structural stability.
Advanced Dual-Platter Architecture
The Air Force 20 incorporates a sophisticated dual-platter system consisting of a 19kg stainless steel main platter and a 6kg upper platter.
When the vacuum system is activated, air is evacuated from a dedicated chamber beneath the record, effectively bonding the record, upper platter and main platter into a single rigid structure.
This dramatically reduces resonance while ensuring the record surface closely conforms to the shape intended during the cutting process, enabling more accurate retrieval of musical information from the groove.
Flexible Tonearm Configuration
The Air Force 20 is supplied with two interchangeable tonearm bases, each capable of accommodating both short and long tonearms.
Sharing the same mounting footprint, the bases provide exceptional flexibility for enthusiasts who wish to explore multiple tonearm and cartridge combinations without compromise.
Supporting the turntable is the newly developed APSU-20 Power & Air Supply Unit. This elegantly designed chassis houses independent air pumps for both the platter flotation and flywheel systems, as well as the power supply electronics. Designed with an exceptionally low noise floor, the APSU-20 ensures stable operation while preserving the integrity of the analogue signal.

A New Chapter for the Air Force Series
The Air Force 20 represents the latest evolution of TechDAS’ pursuit of analogue perfection. By combining vacuum record hold-down, air-bearing technologies, advanced isolation systems, and massive mechanical construction, it seeks to minimise every source of vibration and resonance that stands between the listener and the music.
While still in prototype form, its debut at HIGH END Vienna 2026 suggests that the Air Force 20 is destined to become another landmark product in the celebrated Air Force Series—offering vinyl enthusiasts an extraordinary new reference for analogue playback.
