Focus Zen 4
A fitting tribute to Hephaestus, the Greek god of fire and metalwork, this model appears to operate at a primal level. To see it in action is to watch flames brutally tear at the metal, but somehow be contained and confined to repeat their action over and again for purely aesthetic pleasure.
Zen 4 is complemented by multiple safety features. Although it has a naturally stable form, it is fixed to avoid any risk of inversion. It features the automically extinguishing carbon dioxide detector that acts should any fault arise. It has a fueling feature than ensures it can only be filled when it is safe to do so, and provides a safety cap for its electronic elements. The Zen 4 is only available in a waxed steel finish with visible joins.
