1 Square Ceiling Diffusers : All extruded aluminum constructions. Opposed blade damper is adjustable from face of diffuser. Available in square and rectangular type with one, two, three or four way patterns. MODELS: SCD: Supply ceiling diffuser. RCD: Return ceiling diffuser.

2 Linear Slot Diffusers : Frame and Curved deflection blades are made of extruded aluminum alloy 6063 to T6 heat treatment. Available with GI sheet to control air flow patterns. MODELS: SLD: Supply Linear diffuser. RLD: Return Linear diffuser

Linear Bar Grills : SAMA Linear bar grille " single deflection " is wall mounted grille, used as supply or return grille in cooling, heating or ventilation applications.

3 Linear Bar Grills : SAMA Linear bar grille " single deflection " is wall mounted grille, used as supply or return grille in cooling, heating or ventilation applications. The single deflections linear grille is composed of a set of fixed horizontal straight bars attached to frame, both manufactured from extruded aluminum sections. MODELS: SLBG: Supply linear bar grille. RLBG: Return linear bar grille. SLRG: Supply linear Register. RLRG: Return linear Register

4 Supply Air Grille & Registers : The single deflection air grill is composed of a set of deflecting blades mounted on a rectangular shaped frames. The double deflection air grille is composed two sets of deflecting blades mounted in two adjacent planes. The two sets of deflecting blades are mounted in such a way that one set is vertically mounted and the other set is horizontally mounted. The single and double deflection air grille are used for cooling, heating or air ventilation. MODELS: SAG D/D ( With Damper ) SAG S/D ( With Damper ) SAG D/D ( Without Damper ) SAG S/D (Without Damper )

5 Fixed Blade: SAMA fixed blade is composed of a set of horizontally mounted fixed blades that are made of extruded aluminum. MODELS: FBH FBV FBRV

6 Round Diffuser : Fully adjustable air discharge pattern horizontal vertical, for spot cooling, heating and ventilating application. Removable inner core assembly for easy installation. Aluminum construction. Standard color RAL9016. MODELS : SRCD: Supply Round Ceiling diffuser. RRCD: Return Round Ceiling diffuser.

7 Jet Diffuser : Aluminum construction with extruded aluminum frame. Adjustable core provide air discharge up to 30 degree from the mid position in any plane. Single element provide direct connection to round duct system. MODEL : JD: Jet diffuser.

8 Disc Valve : Air flow rate can be controlled by rotating the central disc. Central disc is fixed by locking nut. Face galvanized steel. Spindle and locking nut galvanized steel. MODELS : DV: Disc Valve.

9 Door Grille : SAMA Door grille composed of a set of horizontally V-shape blades mounted with fixed spacing to a frame called the fixed frame. MODELS : DG: Door Grille.

10 Egg Crate : SAMA Egg Crate frame made of extruded aluminum and core of square aluminum sheet standard color white powder coating to ( RAL 9016 or 9010 ). MODELS: EC: Egg Crate.

11 Fresh Air Intake & Exhaust Louvers: Air louvers is composed of a set of horizontal mounted fixed blades and inclined down 45 Spaced 35 mm or 50mm on center, blades and frame are manufactured from extruded aluminum Alloy ( 6063-t6 ) designed for both intake and exhaust opening.

12 Sand Trap Louver: SAMA sand trap louver manufactured for fresh air intake in HVAC systems, which are designed To separated large size sand particles at low air velocities thus avoiding excessive dust Loading performance for air filtration and moderate pressure drops at low air velocities.

13 Access Door Grilles : The frames are made of extorted aluminum alloy, access door grille core can be fabricate from fixed blade, egg crate and perforated sheets. standard color is white powder coating ( RAL 9016).

Access Door Duct SAMA manufactures Access Doors Duct that are designed for use in central air conditioning ductwork systems to provide access for resetting of Fire Dampers, Heaters, Filters or other

14 Access Door Duct SAMA manufactures Access Doors Duct that are designed for use in central air conditioning ductwork systems to provide access for resetting of Fire Dampers, Heaters, Filters or other maintenance works. The strong and robust construction of the access door guarantees low leakage of air even with high duct pressures. Double walled door panel with mineral wool insulation will act as better resistance for transfer of heat..

is provided manual operation, Extended shaft and motor base is provided for

15 Volume Control Damper : Volume control damper is made of multi blades, parallel, and frame is flange type of Galvanized steel construction, hand locking quadrant is provided manual operation, Extended shaft and motor base is provided for motorized operation. the blades are mounted on nylon bushing and operated by external linkage.

16 Fire Dampers : Fire damper are made of 20 gauge galvanized steel blades are curtain type of gravity shutter without negatron closure spring for static operation or with stainless steel negatron spring for dynamic operation

Fire & Smoke Dampers : Combination fire & smoke damper meet the requirement of safety in HVAC system. FSD consist of a fire damper and smoke damper together as a single damper.

17 Fire & Smoke Dampers : Combination fire & smoke damper meet the requirement of safety in HVAC system. FSD consist of a fire damper and smoke damper together as a single damper. FSD is used in HVAC system where a wall, floor or ceiling is celling is required to have both a fire and smoke damper. FSD close up on the detection of heat ( via duct temperature ) or smoke via ( via smoke detector ). FSD is available with electric heat devices instead of fusible links in regular fire damper.

18 Back Draft Damper : From light operations to heavy-duty industrial applications, SAMA provides the perfect back draft damper. Commercial dampers provide low-pressure openings with excellent pressure-drop performance. The industrial grade back draft dampers offer rugged construction & heavy gage materials to with stand the high velocities & back pressure associated with heavy duty installations. SAMA has developed three types of Back Draft Dampers as following : 1. Light Back Draft Damper. 2. Back Draft Damper. 3. Pressure Relief Damper.

19 Variable Air Volume (VAV) * Variable Air Volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant temperature. * Variable Air Volume Systems are the best way to zone especially in large buildings. A VAV system with the proper controls and set-up will help the building owner realize large savings in energy usage.

20 Sound Attenuators : Sound attenuators are constructed to the relevant of HVAC ducting work. Casing is 20 gauge galvanized steel. Baffle are made of 20 gauge galvanized steel perforated galvanized steel filled with sound obsorbing material. Flange from steel angle.
