IN-LINE MIXED FLOW DUCT FANS ULTRA-QUIET TD-SILENT Series TD-SILENT - MODELS 160 TO 1000 Low profile “Mixed-flow” fans with soundabsorbent insulation. Extremely quiet. Certified of Approval Noise Abatement Society (TD-350, TD-500, TD-800 and TD-1000 models). Manufactured in plastic material, with a specifically designed internal skin to direct the sound waves at the right angle for them to be captured by the sound-absorbent material (1). Fitted with rubber gaskets on the inlet and outlet to absorb vibrations, a body that can be dismantled. Connection box can be rotated 360º, to facilitate easy connection of the power cable. Motors Speed controlable 230V-50Hz motor, of two speed or 3-speed motors (depending on the models). IP44. Motors are class B, with ball bearings and safety thermal overload protection. (1) Except the TD-160 SILENT, that is fitted with the special floating motor system patented by S&P. Additional information The models offer solutions to ventilation problems, especially in places where people work and low sound level is required. TD-SILENT-T models TD-SILENT versions fitted with a run-ontimer adjustable within 1 and 30 minutes and onespeed or 3-speed motors (depending on the model) not suitable for speed control. Low profile “Mixed-flow” fans with soundabsorbent insulation. Extremely quiet. Certified of Approval Noise Abatement Society (TD-2000 model). Constructed from sheet steel with epoxy polyester paint, acoustic insulation (MO) glass fibre, within outer shell. Aerodynamic inlet to improve airflow and reduce sound. Detachable fan unit without demounting duct connections. IP44. External terminal box IP55. Removeable fan body with 3 speed motor, single phase 230V-50/60Hz speed controlable, Class F, external rotor aluminium motor with capacitor and thermal protection. Additional information The models offer solutions to ventilation problems, especially in places where people work and low sound level is required. In-Line duct fans TD-SILENT

IN-LINE MIXED FLOW DUCT FANS ULTRA-QUIET TD-SILENT Series MODELS 250 TO 1000 Low profile The low profile of the TD-SILENT fans makes them the most effective solution for installations where space is very limited, especially in ceiling voids. Low noise level Sound waves produced inside the TD, are directed through the perforated inner skin 1 and absorbed by the layer of sound absorbent material 2 Easymaintenance Removable motor-body assembly to easy cleaning and repairing without touching the ducts. Support plastic brackets simplify the operation. Connection box rotated 360º Connection box...
