Centrifugal type "snail" industrial fan OBR 200T-4K, supply voltage 380 VAC with power 190 W, working opening 115x102 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.
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 1000m.
The degree of protection is IP 44, which does not allow the fan to operate at higher humidity and aggressive environments (containing sticky and fibrous substances) as well as in inappropriate atmospheric conditions.
They operate under conditions of normal fire hazard, according to "fire-building technical norms"
They are mounted on sturdy panels according to the specific case with screws and dowels, bolts with nuts or nut studs. Centrifugal fans OBR 200 are available in two versions - single and three-phase.
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 !!!
The fan flow can be adjusted with a suitable electronic regulator.
