Centrifugal tube fan KSB 200,730 m3/h, whisper-quiet, with soundproof and heat-insulated housing

Compact, radial tube fan KSB 200, whisper-quiet, with back-curved blades, with noise-insulated and heat-insulated casing, air flow 730 m3/hTechnical data:? voltage: 220-240 V/1 PH/50-60 HzCurrent consumption: 0.45 AL Power ratings Output: 730 m³/h, Speed: 2550 min-1 Sound pressure - 3 m: 38 dB (A)Max Mean conveying temperature: -25 +55 °? Protection class: IP X4 ClassWeight: 6.4 kgNozzle size: 200 mmSEV class: Application range: For loading and unloading of various rooms with high requirements on the equipment noise level. The design of the KSB fan offers a wide range of possibilities for installation in confined spaces such as for example behind the suspended ceilings Compatible with ventilation pipes with diameters of 100,125,150,160,200,250 and 315 mm. constructionThe double-walled housing is made of galvanised steel and is insulated from the inside by heat and sound insulation panels made of Dä mm material. The round spigots are rubber-sealed.   Motor2-pole external rotor asynchronous motors and radial runners of the impeller blades, which are crimped with back-curved blades. The motor is equipped with an integrated automatic reset overheating protection. The ball-bearing motor with specially selected ball bearing grease ensures silent running and maintenance-free operation. Rubber vibration dampers in KSB... M model ensure extra vibration damping for engine Some standard sizes are available with a high performance motor (KSB.. S) Speed controlStepless or step-by-step speed control via a thyristor or transformer speed controller. When connecting several fans, make sure that the maximum current and power consumption of the speed controller is not exceeded. e. g. mounting radial fans for connection to round pipes and direct installation in the pipe run. If the fan is mounted over the elastic connecting sleeves, fasten the fan to the building structure with brackets, rods or mounting brackets. The assembly is permissible, in accordance with the direction of air flow (marked by arrows on the fan housing) in any position. Maintenance access must be provided during installation.
