The Flakt Woods JmMax extract fan axial flow fan range of high performance and reliability 2 stage axial flow fans

This fan was introduced to satisfy ventilation systems where high pressure fans are required, where only single phase supply (240volts) is available and speed control is required

A typical application where this fan is commonly used is in the catering industry where a high level of filtration is required, usually the result of fitting odour control via Pre and Carbon Filters*

The build quality and reliability are the highest we have ever experienced, in a range of fans that are designed to work harder than most

Every time you fit this fan you know you’ve made the right choice, and it will enhance your reputation for only using the best quality products

• Fully speed controllable
• Can be used in any non hazardous environment
• Suitable in temperatures from ‑40°C to 50°C
• Low to high air volumes
• Low to high static pressures
• Available sizes 315mm – 630mm from stock

The Casings are spun sheet steel, then hot dipped galvanised to give a finish highly resistant to corrosion and can be mounted externally and internally

The impeller (the bit that goes around and moves the air) is manufactured die cast aluminium

The motors are totally enclosed with class F insulation with protection to IP55.

*High pressure systems can also consist of duct size restrictions, an unusual amount of ducting including a high number of bends, other forms of filtration such as Heppa Filters or Electrostatic filters.
