Blauberg Iso-Mix 250
Sound-insulated inline mixed-flow fans. Maximum air capacity up to 1315 m³/h.
- Designation key
|Supply and exhaust ventilation systems installed in various premises with high requirements to the noise level.For ventilation air ducts requiring high pressure, powerful air flow and low noise level.Compatible with Ø 100 up to Ø 315 mm air ducts.|
|The casing is made of polymer-coated steel, internally filled with 50 mm mineral wool thermal- and sound-insulating layer.Special inner perforation of the casing and sound-insulating material are designed for wide-frequency sound absorbing.Mixed-flow impeller made of high-quality plastic.The diffusor, the specially profiled impeller and directing vanes provide high performance and powerful pressure combined with low noise operation.External airtight terminal block on the fan casing for power supply.Mounting brackets on the fan casing for mounting to the floor, to the wall or ceiling.|
|MOTOR||MODIFICATIONS AND OPTIONS|
|Double-speed single-phase high-efficient motor with low energy demand on ball bearings.Overheating protection by built-in thermal switches.Motor ingress protection rating IPX4.||T: turn-off delay timer adjustable from 2 to 30 minutes.
US: built-in three-position speed switch.
FR – built-in smooth speed controller from 0 to 100 %. The fan is supplied with power cable and IEC C14 plug or mains plug (FR1).
|Speed selection with a built-in speed switch (US option) or an external multi-speed switch (special accessory).Smooth speed control is possible either with an integrated speed switch (FR option), an external thyristor or transformer speed controller (special accessory) when connected to the maximum speed terminal.|
|Due to its compact design the fan is the ideal solution for mounting in limited spaces.The fan is suitable for mounting in any section of the ventilation system from intake to the end of the ductwork.Wall or ceiling mounting with a special mounting plate on the fan casing.|
