In 1992 it was also considered to have an extra-urban phase and since 1997 it has been used for measuring consumption and CO2 emissions. The ﬁrst European driving cycle came into force in 1970 and referred to an urban route. NEDC (New European Driving Cycle): it has been the European driving cycle used so far for the measurement of fuel consumption and emissions from passenger cars and light commercial vehicles. On 1 September 2017, the new Worldwide harmonised Light-duty vehicle Test Procedure (WLTP) came into force in Europe and will gradually replace the New European Driving Cycle (NEDC) protocol. This is important because only a laboratory test, which follows a standardized and repeatable procedure, allows consumers to compare different car models. In this way, the tests are reproducible and the results comparable. Standard finish is powder coat white while other finishes are available to suit the interior and architectural design requirements.The tests to assess fuel consumption, CO2 and pollutant emissions are carried out in the laboratory and are based on speciﬁc driving cycles. The suggested volume control should be from the main duct run take-off, or from a butterfly damper fitted to the inlet of the cushion head box.Ĭonstruction is from extruded aluminium and the recommended maximum length for each section is 3 metres. The air pattern control is adjustable from the diffuser face and is achieved by means of an adjustable pattern control with each slot, enabling a full 180º air pattern adjustment.

(Fixed Core - Model LSD-FC, Removable Core – LSD-RC.

The modules are available with a 20mm or 25mm Slot with the number of slots ranging from 1 to 8 slots and are further available as fixed or removable core. They can also be installed in any type of ceiling application. Slot diffusers can be installed individually in set lengths or in a continuous line. Polyaire Linear Slot Diffusers are an attractive alternative to the ceiling or high sidewall supply diffusers.
