Centrifugal type "snail" industrial fan OBR 200M-4K, supply voltage 230 VAC with power 185 W, working opening 161x146 mm and flow 900 m3/h. It is possible to reduce the fan flow rate with a properly selected frequency regulator.
For installation in production, public buildings and laboratories, in systems for cooling, heating, ventilation, cooling of electric motors, electronic equipment, etc.
Mechanical throttle flow adjustment is not recommended. If the output is fully closed, the fan will develop maximum pressure and zero flow. A measured increase of the consumed current by 7-10% is measured, considering its reduced cooling in this mode of operation, there is a possibility of overheating and irreversible damages of the engine, which may lead to its Guarantee being dropped !!!
The fan flow can be adjusted with a suitable electronic regulator.
