Centrifugal type "snail" industrial fan OBR 140M-2K, supply voltage 230 VAC with power 225 W, working opening 100x90 mm and flow 1100 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.
They operate under normal fire conditions according to "fire-building technical regulations". They are mounted on sturdy panels according to the specific case with screws and dowels, bolts with nuts or nut studs.
The fans are designed to operate in normal climatic conditions, with ambient temperatures ranging from -5 ° C to +60 ° C and relative air humidity at 30 ° C from 40% to 85% above sea level 1000 m.
Mechanical throttle flow adjustment is not recommended. If the outlet 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 could lead to its Guarantee being dropped !!!
