GENERAL CHARACTERISTICS Fan heater LEO Heating capacity [kW] Air flow [m³/h] Weight [kg] Casing Colour EPP is an expanded polypropylene, which is good thermal insulator, is resistant to dirt and has high ability of vibration damping. This features allowed to use it as a material for casing of the unit and lowered its total weight. (2) similar to RAL 9007 (1) APPLICATION LEO fan heaters are designed to operate indoors. They are used to heating rooms with a big cubic measure like industrial buildings, warehouses, departments stores, production halls, sports halls (gyms), sacral buildings etc....

CONSTRUCTION BMS/SYSTEM FLOWAIR Connection of units to the BMS system (Building Management System) is possible via a T-box or HMI controller or via the DRV control module. LEO is also a unit adapted for integration with the SYSTEM FLOWAIR. 3-SPEED FAN LEO fan heaters are equipped with 3 speed fans. It’s the simplest and most effective way to control the fan heater’s operation. EPP CASING Mechanical strength, resistance to dirt, low weight and aesthetic look. By applying expanded polypropylene for casing construction, LEO fan heaters create a new quality in heating and ventilation. MIXING...

RANGES HORIZONTAL RANGE OF AIR STREAM – isothermal Horizontal range of isothermal stream at velocity boundary equal to 0,5 m/s. VERTICAL RANGE OF AIR STREAM – non-isothermal Vertical range of non-isothermal stream at velocity boundary equal to 0,5 m/s.

the above air flow velocity charts refer to the isothermal stream LEO • Air heating and ventilation

INSTALLATION AND VARIOUS MOUNTING POSSIBILITIES Possibility of setting the direction of air stream installation under the ceiling DxE vertical installation using the console When unit is mounted under the ceiling please note the proper non-isothermal air stream range. Rotary console It enables installation of the heater perpendicularly or horizontally at various angles to the partition. Optional corner holders There are corner brackets available which make installation and levelling of the heater easier. RECOMMENDED INSTALLATION DISTANCE [m] S1

INSTALLATION TIPS Steady air circulation should be provided in the entire room. Correctly installed heaters should direct the air to the occupied zone. Heaters installed in the corners should direct the air to the center of the room. Heaters installed on the opposite walls should be overlapped. Air outlet should not be limited. Air inlet should not be limited.

ACCESSORIES - CONFUSOR LEO Dedicated for LEO L and XL Confusor increases air flow speed. It results in faster air distribution to the lower zones of the room. The use of a confusor causes a 10 % reduction of unit’s parameters as compared to nominal data given in the tables on pages 23–25 Material: powder painted metal RAL 9007 Weight: 3,8 kg - confusor LEO L 6,2 kg - confusor LEO XL When unit is mounted under the ceiling please note the proper nonisothermal air stream range. ACCESSORIES - 4-SIDE OUTLET GRILLE LEO Dedicated for LEO L and XL 4-side outlet grille improves air distribution. It...

ACCESSORIES - MIXING CHAMBER KM Available to all models LEO LEO + KM LEO fan heaters with LEO KM mixing chamber form heating and ventilation unit. It is the easiest way to create the efficient mechanical ventilation without additional systems. 1095 For CAD drawings, Revit files and documentation for all available versions of LEO visit www.flowair.com

INSTALLATION installation under the ceiling LEO + KM + UVO installation using pins installation using brackets Installation brackets Enable easy and aesthetic installation on the walls. For units installed vertically. When mounting under a ceiling, the mounting height should be selected depending on the non-isothermal vertical range.
