Fast Flow Primo™ range of outlets are Fast Flow’s premier and most comprehensive range. The Primo™ range works on all types of roof and gutters. With 4 outlets in the range each with its own unique capabilities, capacity and project suitability, there is a Primo™ outlet for all types of buildings. All Primo™ outlets consist of a stainless steel baseplate and a cast aluminium alloy (epoxy coated) air baffle. Additional to this, installation kits are available for either metal gutter installation (cast aluminium counter flange, EPDM seal and stainless steel nuts and bolts) or concrete (R.C.) roof areas and car parks (stainless steel up turned clamping ring and stainless steel nuts). The drainage capacity for the Primo™ series ranges from 20 l/s to 150 l/s.
