The MXFJ25W Martec Jet features built in draft shutters that are forced open as the fan is in operation, which means that once the fan is turned off they return to the closed position. For this reason it is advisable to have ample clearance above, we would recommend a minimum of at least 300mm. This unit is designed to be non ductable and may be an easy like for like replacement for an old ceiling mounted exhaust fan.
MXFJ25W Features:
• DIY installation fitted with a flex and plug
• Powerful air extraction
• High performance long life ball bearing motor
• Quiet operation
• Removable fascia for easy cleaning
