Description	FDMB FDMB – The Damper in the HVAC equipment duct that prevents the spread of fire and combustion products from one fire segment to another by shutting off the airflow at the fixture points.	SL Linear slot diffuser for supply air with multiple slots (one:SL1, up to ten:SL10) made by anodized aluminium. The air jet is adjusted by one blade (plastic in black or white color) in every side of each slot and can get any direction (180o arc). Also the blades can close the slot. Ceiling or wall mounted. For use in heating and cooling cases, in low and medium installation height. Noise and pressure drop remains the same in any position of the blade. Electrostatic paint of the frame in RAL color is possible.	EX Door grille made by anodized aluminium. For air transfer between two rooms without visual contact between them. The blades are “Λ” shaped. There is flange in both sides of the grille. The blades are parallel to the first mentioned dimension. Electrostatic paint in RAL color is possible.	D Multiple leaf air volume control damper for installation in the majority of grilles or diffusers. Made by aluminium. With simultaneously opposite rotated blades. The regulation is possible from the front of the grille/diffuser with screwdriver or a handle.	AMB-Φ42 Jet nozzle, made by plastic, with adjustable head in any direction. Active diameter 42mm. It is produced only in some colors. For wall (for cooling and heating) or ceiling (only for heating, for air-curtain or to avoid condensation in glass surfaces) installation.	O Ceiling diffuser, square or rectangular, with fixed blades in angle 45o (anemostat), for supply or extract air. With one (O1), two (O2), three (O3) or four (O4) way throw pattern. Accessible. Made by anodized aluminium. Electrostatic paint in RAL color is possible. For use in cooling cases or in heating if the installation height is small.
