75% aluminium mechanical keyboard

The NuPhy Air75 v3 is a low-profile mechanical keyboard with an 84-key layout and a solid aluminium top case. Red nano switches provide a linear feel suited to fast gaming and long typing sessions. North-facing RGB LEDs shine through double-shot PBT keycaps for clear legends. Three connection modes — wired USB-C, 2.4 GHz and Bluetooth — cover desktop, laptop and mobile devices.

Gamers wanting adjustable actuation

Hall-effect switches let you set the actuation point and enable rapid-trigger behaviour for competitive play. The 8 kHz polling rate reduces input latency on PC. Hot-swap sockets accept additional low-profile switches if you prefer a different feel. Buyers who need a full-size layout with a numeric keypad or a built-in palm rest will not find those features here.

Hall-effect switches with adjustable actuation

The defining specification is the magnetic switch design that allows per-key actuation adjustment and rapid-trigger mode. This separates the board from conventional mechanical keyboards that use fixed actuation points. If your workflow or games benefit from customisable trigger depths, this keyboard matches that requirement.

Questions about this item

Will the 12.56 inch width fit my compact desk space?

The keyboard measures 12.56 inches wide, 5.07 inches deep and 0.52 inches high at the front, so check those exact dimensions against your available desk area.

How do I swap the Red nano Switches using the included puller without damaging the hot-swap sockets?

Pull the keycap straight up, then grip the switch housing with the puller and pull vertically; inserting the new switch at an angle bends the socket pins, so keep it perfectly vertical.

When should I replace the double-shot PBT keycaps or Red nano Switches after heavy gaming use?

Double-shot PBT legends do not wear through, and the Red nano Switches are rated for tens of millions of actuations, so replacement is only needed if a switch feels gritty or a keycap cracks.
