TECHDAS AIR-FORCE 20 TURNTABLE — HOW IT WORKS


TechDAS Air-Force 20 turntable — how it works, in four ideas…


Air Float & vacuum hold-down

The heavyweight platter rotates while levitating on a ten-micron cushion of air. Vacuum suction draws each record flat against it, integrating disc and platter into one mass.

Flywheel air-bearing drive motor

Inherited from the Air Force Zero. A flywheel floating on air multiplies the system’s total moment of inertia fivefold and couples to the motor without contact minimising friction, eliminating cogging.

Dual-structure platter

A non-magnetic SUS316L main platter with a selectable upper layer – A7075 Extra Super Duralumin or TP340 pure titanium – vacuum-bonded into one ultra-rigid mass.

Monotube Oil-Damped Spring Suspension

The hybrid spring-and-oil suspension of the Air Force Two, re-engineered: an isolation spring sealed in damping fluid, working against a free-piston oil chamber to settle the platter in silence.
