Options and accessories ■■ ■■ ■■ ■■ Wall bracket, ceiling bracket, IPN additional kit Filter box 2-channel mixing box with built-in filter Specific diffuser (on door, high-level etc.) ■■ ■■ ■■ ■■ Damper and outdoor kit IP30 or IP54 room thermostat LS/HS switch for 3-PH fan motor assembly 5-speed autotransformer for single-phase AC FMAs Operating principle Air heaters are installed at the end of a central heating or cooling system (boilers, air-source or water-source heat pump, reversible production unit). Description AIR TREATMENT ■■ High-efficiency fan motor assembly Silent FMA featuring an aluminium epoxy polyester-coated airfoil propeller to ensure the best compromise between air flow efficiency and acoustic comfort. The ROTOREX design (windings inserted in the fan hub keeps the motor cool to ensure that it operates at optimum efficiency. Two versions are available : • THREE-PHASE 2-speed (accessory: LS/HS switch) • SINGLE-PHASE 1 variable speed (accessory: 5-speed autotransformer) ■■ Casing • Elegant galvanised steel casing, pre-painted with RAL 7035 (light grey). • Condensate drain pan built-in for cooling applications, featuring an antibacterial design (perforated bottom) and quick-release fitting. • Intake section optimised for improved air flow performance and acoustic comfort level. • Advantages: -- Its classic design means that it can easily blend into the architecture of the installation site. -- No need to add an unsightly condensate drain pan. 590 -- C  ondensate pipes quick and extremely simple to connect, without any need for a clamp. ■■ Diffuser Double deflection diffuser made from rigid aluminium sections, based on the BERNOULLI fluid flow principle and on NACA0012 airfoils, creating a high induction rate on the primary air, in order to increase the air throws, limit the stratification phenomenon and thereby reduce energy consumption. • Basic version (for 42AM 63S only): -- Single-deflection diffuser with directional louvre -- Light-grey galvanised steel louvre • JET+ version (fitted as standard): -- Double deflection diffuser -- JET+ aluminium louvre with NACA0012 airfoil design -- Each louvre is directional -- Advantages: -- Air flows adjustable in 4 directions for optimum coverage of the area to be handled, while limiting draughts. -- Laminar air flow for better acoustic comfort (zero turbulence at the diffuser outlet). -- Increased air speed, thanks to the resulting aerodynamics (depression along lower surface of blade) due to the curve of the airfoil, thereby increasing the air throws and the induction rate. -- Limited stratification phenomenon. -- Reduced building warm-up times: -- Recorded energy savings of 15 to 20%.
