You will find alternative types of grilles, especially in stainless steel and automatic or motor-driven options in the HESCO sales programme (separate catalogue). They are suitable for installation in walls, floors, doors, rectangular and circular ducts. The installation can be carried out directly into a duct cut-out or into a subframe, e.g. builders work. The various constructions of grilles in aluminium, steel or plastic with vertical or horizontal, adjustable or fixed blades are shown and described on pages. To optimise air distribution, it is possible to choose from various types of rear assemblies, see pages 8 and 9. 2

They are also available on request with spring clip fixing. Type AT Type VAT The grilles type AT have horizontal aerofoil blades, whilst type VAT has vertical aerofoil blades with a border that is either 2 or 2 mm wide. The front blades can be individually adjusted. In addition to the concealed fix the grilles can also be supplied with spring clip fixing on request. In the 2 mm wide frame version, the grilles are also available with visible screw fixing (border counter punched). Type AGS (non-vision grille/door grille) Non-vision grilles type AGS are suitable for air transfer and exhaust air. They consist of a surrounding front border with horizontal, fixed inverted vee blades and are suitable for visible screw fixing (border counter punched). The grille can be supplied on request with a matching rear frame for door installation (type AGS-T, see also page 11). Materials The grilles are made from aluminium extruded sections.

Aerodynamic Data Supply Air Grilles Flow Volume Determination Air Stream Deflection Determination of volume flow The volume flow can be determined by measuring the air velocity with zero blade divergence using either a pitot tube or a rotating vane anemometer. Pitot tube (Figure 1): Measurements of air velocity should be made between the blades at a number of positions to determine an arithmetic mean value v eff.mean. The volume flow is then calculated as follows: V. t [l/s] = v eff.mean [m/s] x A eff [m 2 ] x 00 V. t [m /h] = v eff.mean [m/s] x A eff [m 2 ] x 00 Rotating Vane Anemometer (Figure 2): The measurement instrument should be evenly traversed across the entire grille face to determine a value of v eff.mean. The volume flow is then: V. t [l/s] = v eff.mean [m/s] x A eff [m 2 ] x 1. x 00 V. t [m /h] = v eff.mean [m/s] x A eff [m 2 ] x 1. x 00 Volume Flow Measurement Figure 1 Figure 2 Correction Factors (where L = const.)

Specification Text Grilles, are suitable for supply or extract air, preferably in walls, sills and ducts, consisting of the perimeter front border (border sections mitre-cut, seamlessly joined together) with peripheral seal and front blades. ASL and SL types with stylish diffuser-type border design. AT, VAT, TR and TRS types with stylish border incorporating an inside edge bevel and angled section to the outside. ASL, AT, SL, TR and KS types: individually adjustable, horizontal front blades. VAT, TRS, TRS-K and TRS-R types: individually adjustable, vertical front blades. AH and AGS types with fixed, horizontal front blades. AWT types with fixed, horizontal front blades; for use in gymnasiums and sports halls, ball-impact resistant according to DIN 1802/part. AGS-T types with matching rear border for installation in doors with a thickness of 0 0 mm. AF types suitable for installation in floors, fixed horizontal blades, core completely removable by use of the special spring clips, subframe with builder s cleats. TRS-K types suitable for direct installation in the duct. TRS-R types suitable for direct installation in circular ducts of various diameters. The ducts and circular ducts do not have to be graded. With special hit and miss flow control with air flow straightener (-K/R), for optimum air flow equalization and flow volume regulation. Grille cores in EF/EFG types consisting of fixed horizontal blade profiles located with spacer tubes, suitable for infill of openings in sills and walls. EF with 12. mm blade pitch, EFG with 1. mm blade pitch, -0 straight blades, -1 with blades inclined at 1. Linear grilles consist of end sections with a border at one end and on both sides and intermediate sections with borders only on both sides. The required linear length is either made up with two end sections or two end sections and the required number of intermediate sections. AH types with fixed, and SL types with individually adjustable, horizontal front blades, installation with subframe and concealed screw fixing, duct opening equals nominal size (L x H). AF types with fixed horizontal blades, core completely removable by use of the special spring clips, subframe with builder s cleats. Rear assemblies/volume flow adjustment components To optimise the air distribution, rear assemblies are fitted. These can be adjusted from the grille face without its removal. -D: Set of adjustable rear air pattern control blades which are installed at 90 to the front blades. -AG: Opposed blade action flow rate controller with screw driver adjustment. -DG: as in -D in combination with -AG. -AS: Hit and miss control with air flow straightener for flow volume regulation. Adjustment via two screws and sliding the lower slotted plate. -R/K: Angled hit and miss control with air flow straightener for flow volume regulation. Adjustment via two screws and sliding the lower slotted plate. With optimum configuration for flow rate control and flow equalisation when grilles are directly installed into rectangular or circular ducts. ASW, AGW, DGW flow volume control dampers for duct installation with surrounding angle border. Otherwise, construction and function as -AS, -AG and -DG. Materials Aluminium: ASL, AT, VAT, AGS, AH, AF, AWT Grille face from aluminium extruded section, natural anodised finish, E-C-0. Steel: SL, TR, TRS Grille face from formed sheet steel, the surface is pre-treated and then powder coated in pure white (RAL 90). Galvanised steel: TRS-R, TRS-K Grille face from formed, galvanised sheet steel. Rear assemblies made from formed or profiled steel sheet, phosphate treated, stove enamelled black (RAL 900) using electro-dipcoat process, resistant to saturated environment for a minimum of 0 hours without deterioration (DIN 001). ER subframe from formed and profiled, galvanised sheet steel. Plastic: KS Front grille and rear assemblies in extruded plastic section (hard PVC), dark grey (similar to RAL 011), temperature resistant up to 0 C. Curved blades for flow control in black or dark grey. Installation: ASL, AT, VAT, AH and SL types using an ER subframe and concealed screw fix, duct opening equals nominal size (L x H). AWT, AGS, TR, TRS, TRS-K and TRS-R types with visible self-tapping screws (counter punched in front border), duct opening equals nominal size 1 mm (L 1 mm/ H 1 mm). KS types as before, however front border with screw fixing holes. 21
