Type AXPS & Type AXPT
The AXP series of fixed blade diffusers are designed to be applied in air conditioning and ventilation systems, where a mounting height diffuser of more than four metres is desired, obtaining a high induction index and therefore a resulting stratification.
The ability of the vanes to be moved make it possible for the graduation of the air distribution to be set for either cold or hot air and discharged either horizontally or in a cone fashion. Diffusers are set for heights of up to three metres with a temperature differential of up to 10°C.
