Involving advanced techniques and solutions FLOWAIR, managed to decrease LEO FB fan heater production costs and weight, yet maintaining its quality. The new casing of LEO FB fan heaters is made of EPP (expanded polypropylene). Very elastic, light and solid material – resistant to bends and breaks under dynamic and static loads (e.g. if dropped down or under impact stress). This material is chemical-resistant, easy to clean, it absorbs heat, noise and vibrations. New upgraded mounting consoles (brackets) for new air heaters. Ability to turn both sides at 170° angle makes unit guiding towards required direction even easier. Due to good-looking casing and unique design LEO FB EPP fan heaters meet high aesthetic requirements and maintain the same functions for more favorable price.

LEO FB fan heaters are designed for heating of industrial, business and other large areas. LEO FB fan heaters include a fan and heat exchanger with connection for hot water. Hot water heats up heat exchanger, fan blows the heat evenly to premises (Fig. 1). Water may be supplied from: solid fuel boiler, gas fired water heater, pellet boiler, from municipal utilities or other heating equipment.

Fast and uniform heating of premises is the key advantage of fan heaters. Such type of heating is non inertial; feeling of heat comes immediately after unit start up. Programmable controller provides considerable energy saving, yet maintaining the heat comfort.

Choosing LEO FB fan air heaters with EPP casing brings the same high quality for better price!

Advantages of LEO FB fan heaters with EPP casing:

  • Heaters are developed and produced by company FLOWAIR. This company specializes in production of such type of heaters only and is the number one in a competitive Polish market!
  • Same quality and functionality for better price!
  • EPP casing. Solid and elastic EPP casing serves for lower weight of the unit. This material is chemical-resistant, easy to clean, it absorbs heat, noise and vibrations.
  • Heaters are made of highest quality parts: qualitative Czech LLOYD heat exchanger, unique German EBM fan.
  • Quality guarantee – European product with technical properties meeting the declared values, CE certified.
  • Modern and attractive design will be appreciated by any owner of premises.
  • Silent and economical fan performance. Plastic blades and German brushless motors of new generation ensure silent fan performance and minimum electricity consumption.
  • Low weight. LEO FB fan heaters feature low weight, therefore solid supporting structures are optional. Heater can be installed by one person.
  • Suitable for cooling and ventilation of premises. By applying cold water, the purpose of LEO FB may be changed from heating to cooling. Outdoor fresh air supply requires additional connection of recirculating chamber.
  • Extensive application: industrial buildings, workshops, car showrooms and washing sites, warehouses, pavilions, sport halls, exhibition and meeting rooms, supermarkets, churches, logistics centers and other facilities.
  • IP66 fan selection choice. These fans are dust and high humidity resistant, therefore are especially suitable in areas full of dust and humidity.
  • 5 YEAR WARRANTY.
