    Information
    Ventilation diffusers are fitted to the discharge ends of ducting systems where air is to be supplied to occupied spaces. They have a number of functions besides making the end of the duct look more aesthetic.

    A supply duct is connected to the plenum box of a ventilation diffuser. The plenum slows the air velocity down which makes the air discharge less noisy as it enters the room and means that the discharge air velocity is less likely to create a draft nuisance. The diffuser facings are available in various designs to create an airflow pattern within the room and an aesthetic to suit the application.

    Ventilation diffusers are all about delivering air into occupied spaces effectively but unobtrusively.

    Puravent supplies an extensive range of diffusers suitable for a wide variety of ventilation systems. Here you will find high induction diffusers, linear diffusers, nozzle diffusers and many more products in different sizes and fittings. If you require any assistance, please call us on 01729 924108 to discuss your requirements.
