The noiseless canal fan system is designed to quietly cold AV equipment rooms and closets, and to ventilate different air circulation and exhaust projects. a DC-motor with PWM-control for a noiseless and energy cost-effective performance. The motor box containing the fan 's impeller and blades can be from the mounted frame for painless cleaning and maintenance. an brainy controller that features forward-looking programming and functions. Kit also two canal clamps and everything needed to mount the unit and power it through an outlet brainy Controller The controller features an on-board processor with active temperature monitoring that will automatically adjust fan speeds to respond to varying temperatures. For non-cooling ventilation applications, the controller can be to run continuously at customizable speeds with power on-off memory. added features an alarm system and eco-mode. detachable 8-foot precision caloric probe that is water unsusceptible . noiseless and Energy cost-effective Design a DC-motor that is disciplined using PWM -LRB- Pulse Width Modulation -RRB-. This technology the canal fan to be capable to run smoothly at extremely lowset RPM speeds without generating added heat or noise. In addition, the canal fan a intermingled flow design for a superior inactive pressure rating. The motor duple ball bearings rated at 67,000 hours which allows the canal fan unit to be mounted in any direction. The unit is rated to be highly unsusceptible to dust and liquids, and performs well plane in unpleasant environments.Applications This noiseless canal fan system is fashionable in a variety of applications including chilling AV equipment rooms, closets, racks, and cabinets. also in use in different air circulation and ventilation projects including aquicultural grow rooms and tents, draining bathrooms and attics, and some other installations.
