DSL / DSL-D Linear Diffusers

    • Product Details


      The Waterloo large format linear diffusers series DSL are ideal for most commercial supply and exhaust systems and integrate well with ceiling tile and lighting layouts. The clear design provides an extremely low air resistance characteristic and this makes the diffuser ideal for any fan coil or induction system which is pressure sensitive.

      Single or multislot diffusers are available with fixed 1 or 2 way air patterns; multislot 2 way diffusers may be adjusted to suit site conditions by changing vanes. The diffusers are constructed from aluminium alloy extrusions fixed or clipped to cross stays. Internal vanes are removable for installation, access or cleaning.
