Heating and Air-conditionig Equipement manufacturer
Thermal comfort and air quality



Agricultural machinery, construction equipment, utility and industrial vehicles are subjected to stress to use difficult. The strength of air diffusers for these applications is an essential feature. SNDC air diffusers ensure optimum operation.


Open and close air louver


Offered at competitive rates, SNDC swivelling and closabe louvers enable to adjust the direction and the rate of air flow according to the desired comfort.

Standard or custom colour

Available as standard in black color (part number 370C42) or bicolored (black and gray shutters – part number 370C44) SNDC's air diffusers can also be made on demand, for serial productions, in specific colors and integrate your logo embossed on the air shutter.

Tested sturdiness and durability

The resistance of the SNDC air louvers was tested and approved on two automated test benches in different operating temperatures (-35°C and +80°C).


The first automated bench tests the resilience to rotations of the air louvers (in the configuration 2, with its swivel guide support), while the second one tests the orientation, opening and closing of the flaps. In both cases, over 50 000 cycles have been completed without the slightest failure. This amount of cycles is well exceeding the amount of cycles that an air diffuser will have to perform during its life time.
