MTD Silent Series - In-Line Mixed Flow Duct Fan

Low profile Mixed Flow fans with sound-absorbent insulation Extremely quiet. The low profile of the MTD Silent fans makes the most effective solution for installations where space is limited such as in ceiling voids. Both air and sound performance ratings are tested and certified by AMCA, in accordance to AMCA211 and AMCA311 Standards.

Additional Information The models offer solutions to ventilation problems, especially in places where people work and low sound level is required. Accessories MCA-S • Non-return flaps to be installed at the fan discharge. They prevent heat leakages when the extractor is not operating. MRJ-S • Grilles mounted at the inlet or outlet of the fan to prevent the entry of any foreign objects that could damage the fan. MBR-S • Flanges allowing the coupling of MTD-Silent fans in series. MAR-S • Rectangular Duct Adapters enable connection to rectangular ducting. MPC-S • Flow detectors designed to correctly measure pressures at the inlet with airflow straightener. Construction MTD Silent 100/2~200/2 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 Fitted with rubber gaskets on the inlet and outlet to absorb vibrations, a body that can be dismantled. • Connection box can be rotated 360°, to facilitate easy connection of the power cable. • The low profile of the MTD 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. • Motors are Class B, with ball bearings and safety thermal overload protection. MTD Silent 250~315 General • Constructed from sheet steel with epoxy polyester paint, acoustic insulation (MO) glass fiber, within outer shell. • Aerodynamic inlet to improve air flow and reduce sound. Detachable fan unit without demounting duct connections. • The models offer solutions to ventilation problems, especially in places where people work and low sound level is required.
