| | | For medium to smaller air flow volumes against high resistances. Specially designed to be installed in-line in circular ducting. High pressure characteristic to overcome resistances of bends, filters etc. Universal in application for domestic, commercial and industrial purposes. ■ Special features Compact design to minimise space and cost using in-line installation. Intake and exhaust spigot fit into standard duct sizes. 100% speed controllable to achieve any required duty. Installation in any position. Extensive accessory range. Optimised aerodynamic casing design. | | |
| | | ■ Specification SilentBox® Casing Like an internal attenuator. Acoustically lined with abrasive resistant 50 mm thick mineral fibreboard. Four quick release clasps permit easy access to motor scroll and impeller set. Swing out motor and impeller. Spigots on intake and exhaust with twin-seal rubber gaskets fit into standard ducts. All parts manufactured from galvanised sheet steel. Electrical connection Terminal box (IP 55) is supplied with a 60 cm long electric cable. Impeller Low noise forward curved centrifugal impeller, housed within an aerodynamically shaped scroll made from galvanised steel. Bell mouth shaped inlet ring to achieve optimum air flow. Motor protection Motors have thermal contacts wired in series with the windings. To reset the thermal contacts the main supply must be switched off. | | |
| | | I Features of all models Motor Low noise external rotor motor with ball bearings, impregnated windings insulation class B, designed for continuous operation, maintenance free and radio suppressed. Speed control Stepless 0 - 100 % by use of electronic controller or 5 stepped by low noise transformer. Installation Installation in any position without restriction: - horizontally, vertically or pitched - suitable for intake or extract. To keep sound levels inside the ventilated rooms as low as possible we recommend the fan is installed as remote as possible. | | I Specification RR Casing Made from robust galvanised steel for harsh working conditions. Spigots on intake and exhaust fit standard ducts. Electrical connection Terminal box (IP 55) located on outer casing. Impeller Backward curved centrifugal impeller made from polymers. Directly fitted on motor and dynamically balanced as a unit providing low noise levels and high efficiency. Motor protection Motors have thermal contacts wired in series with the windings which automatically reset. Protection class When installed in ducting the fan is rated IP 44. | | ■ Specification RRK Casing All components are made from corrosion and impact resistant polymers. Six guide vanes increase the fan's efficiency. Colour: Helios-red. Electrical connection Terminal box (IP 55) located on outer casing. Impeller Backward curved centrifugal impeller made from polymers. Directly fitted on motor and dynamically balanced as a unit providing low noise levels and high efficiency. Motor protection Motors have thermal contacts wired in series with the windings which automatically reset. Protection Splashproof to IP 44. | | |
