2 Mixed low In-Line uct an MT Silent Series MT Silent 100/2~200/2 MT Silent 250~315 Low profile Mixed-flow fans with sound- absorbent insulation. xtreme ly quiet. General Manufactured in plastic material, with a specifically designed internal skin to direct the sound waves in the right angle for them to be captured by the sound-absorbent material. itted with rubber gaskets on the inlet and outlet to absorb vibrations, a body that can be dismantled. onnection box can be rotated 360, to facilitate easy connection of the power cable. The low profile of the MT Silent fans makes them the most effective solution for installations where the space of installation is limited such as false ceilings. Motors Speed controllable 230V -50Hz motor, of two speed motors. IP 44. Low profile Mixed-flow fans with sound- absorbent insulation. xtreme ly quiet. General onstructed from sheet steel with epoxy polyester paint, acoustic insulation(mo) glass fibre, within outer shell. erodynamic inlet to improve air flow and reduce sound. etachable fan unit without demounting duct connections. Low profile fans MT Silent 250 and MT Silent 315 are ideal for installations where space is very small, as in false ceilings. Motors IP 44. xternal terminal box IP 55. Removable fan body with two speed motor, single phase 230V -50/60Hz speed controllable, lass, external rotor aluminium motor with capacitor and thermal protection. Motors are lass, with ball bearings and safety thermal overload protection. dditional information The models offer solutions to ventilation problems, especially in places where people work and low sound level is required.
