Compact low profile design Duct Sizes 100 – 500mm Performance - Airflow 0.01 to 1.2m3/s, Pressure up to 650Pa Latest energy saving EC/DC motors Internal mounting IPX2 Manufactured controlled to BS EN ISO 9001 Performance tested to BS848 Part 1 & 2 The new range of Slimpak EC twin in-line duct fans incorporate energy efficient EC motors and basic commissioning controls to offer an energy efficient twin extract fan system. Manufactured from prime quality galvanised sheet steel the Slimpak (SLPT EC) twin fan units are internally treated with an ‘O’ class rated, BS476 part 6 & 7, acoustic foam, which offers the benefits of high sound absorption, good thermal insulation properties in addition to self extinguishing properties and resistant to ignition. The housing is designed to be as compact as possible for concealed false ceiling applications yet is suitable for ceiling or floor mounting, nonreturn dampers can be easily rotated on site to suit the application. Electrical Motors are single phase 230V +/- 10% / 50/60Hz / 1ph (size 100400mm) or 400V +/- 10% / 50/60Hz / 3ph (size 500mm), (4 wire systems only). Performance/Sound Extensively tested to BS848 parts 1 & 2. Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at reference level of 2x10-5 Pa. The inlet/outlet sound power level spectra figures are dB with a reference of 10–12 watts. Quality Assurance Motor / Impellers All SLPT EC units feature a low energy, Class 1, EC/DC external rotor motor and backward curved impeller assembly specifically chosen for performance and non-overloading characteristics. The assembly is dynamically balanced to DIN ISO 1940 Grade 6.3, duct size 500mm rated IP54, all other sizes, IP44 according to BS EN 60529. Ball bearings are greased for life.
