Micro-Perforations

Micro-Perforations are 0.2mm laser cut holes. The number of holes is calculated precisely to match the air volume and pressure available. This gives Micro-Perforations several advantages over Permeable Material Competitors. (1) The air delivery is based upon an accurate, calculated and laser cut diffusion area (rather than an approximate permeable value per m2) meaning more accurate air and pressure control and more efficient operation of the AHU plant (2) Micro-perforations don’t allow the same level of dust build up within the duct as we’re not squeezing the air between loose fibres – meaning less blockage and lower operating pressures over time leading to higher performance and AHU plant efficiency. (3) We can place the micro-perforations anywhere upon the duct circumference. This allows us to create a variety of low velocity air patterns and avoids the ‘dumping’ of air immediately below the duct associated with permeable only Textile Diffusers when cooling with a wide temperature difference. We use Micro-Perforations mainly for cooling and for make up air / tempered fresh air.
