About Linwood

Linwood Plenums was established in 2009 and has grown to become a leading supplier of high quality, low cost air plenum boxes suitable for installation with leading split system air conditioning manufacturers such as Mitsubishi Electric, Daikin, Fujitsu General, LG, Samsung, Panasonic and Toshiba

We manufacture in house from our production facility in Leeds, UK where we have the ability to make plenum boxes using both CNC and vacuum forming machines.

The majority of our customers are based in northern Europe although we have shipped to most parts of the world including the USA, New Zealand, French Polynesia and Africa.

All our products are manufactured using ABS thermoplastics which gives a key advantages over traditional materials such as galvanised sheet metal. These advantages include:

  • Increased thermal resistance reducing the risk of condensation
  • Lightweight construction
  • Easier to handle / install
  • No sharp edges - safe
  • High impact resistance means no bending
  • Ability to recycle

Wherever possible, we manufacture using recycled materials.
