The SJMF inline mixed-flow fan is a fast-fitting unit, saving you time whilst delivering on performance. This high-performance EC fan is mounted in line with the ducting, moving noise away from occupants.
Features and Benefits
- The EC brushless motor means even at full speed, its performance is smooth, quiet and super efficient.
- The double mixed flow impeller produces strong pressure at any speed, allowing the fan to slow down and deliver the exact performance needed. This reduces heat loss through over-ventilation.
- Detachable bracket on 150 to 315mm models for ease of installation.
- Speed control is achieved by removing the 3.5mm Jack plug hub and fitting supplied cable. This can then be paired with optional accessories and sensors for complete control.
- Easy Installation, fitted with a 1.5 metre Mains lead complete with UK 3-pin plug, convenient for connecting to electrical sockets and providing a means of isolation/disconnection.
- Low power consumption at high performance resulting in Low Specific Fan Powers for Building Regulation Compliance.
Specification
- Manufactured with aluminium or cold rolled steel sheet, dependant on size.
- Brushless EC motors are fitted as standard. The IPX4 motor contains sealed-for-life heavy-duty NWB bearings. All motors are suitable for use in ambient air conditions up to +60℃.
- Features a directly driven, integrated, high-efficiency jet design double mixed flow impeller .
- Electrical connection via 1.5 metre Mains lead complete with BS1363-1 UK 3-pin plug BS1361 fuse 3A.
- Supplied suitable for fixed speed operation. A detachable 5-metre lead with a 3.5mm jack connection to the unit is supplied for connection to a remote potentiometer, 0-10VDC or PWM Circuit.
- Please note the design of the unit varies between 100mm, 125mm and 150mm units and above. This is due to airflow optimisation per size.
Quality Management
- Units are designed and manufactured with procedures as defined in BS EN ISO 9001.
