The Numeri JND range of eyeball jet diffusers are designed for wall applications to project large volumes of air over long throw distances. It is constructed of aluminium and has an adjustable eyeball jet diffuser allowing for accurate air distribution. The JND is available in a variety of sizes. The standard colour is RAL9016.

The JNDSW range of eyeball jet diffusers are designed for wall applications to project large volumes of air where a reduced throw length is required. The body of the JNDSW is identical to that of the JND but with a black painted steel swirl insert fixed into the neck of the diffuser.
