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.

-- 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%.
