Technically the font is known as 'Dyson Sans' and is for internal use only, i.e. it's a custom design and private IP, not available externally (and tightly controlled internally). It is used - inhouse - exclusively for technology naming and product family names, not for general use. The secondary font is 'Futura BT for Dyson', a slightly tighter spaced version of Futura than commonly available. HTH.
