Description

Roof fans - Types and design features Wolter roof fan units are suitable for mounting on different roof types. There are two versions available: Type RH with horizontal discharge for the exhaust of mildly polluted air Type RV with vertical discharge for the exhaust of more heavily polluted air تعد وحدات مروحة Roof fans - Types and design features مناسبة للتركيب على أنواع مختلفة من الأسقف. هناك نوعان من الإصدارات المتوفرة: اكتب RH مع التفريغ الأفقي لعادم هواء ملوث بشكل معتدل نوع RV مع التفريغ الرأسي للعادم المزيد من الهواء الملوث بشدة غلاف RH تصل إلى حجم 500 ، يتكون الطربوش من دليل على المياه المالحة الألومنيوم ، من حجم 560 فصاعدا ، يتم تصنيع الطربوش من ألواح الصلب المجلفن الإسكان RV مصنوع من الألومنيوم دليل على المياه المالحة RVS مع غطاء الصوت المدمج في التوهين Casing RH up to size 500, the cowl is made of salt-water proof aluminium, from size 560 onwards, the cowl is manufactured from galvanised sheet steel RV housing is made of salt-water proof aluminium RVS with built-in sound attenuation hood Impeller The backward-curved impellers are mounted directly onto the rotor of the external rotor motors. The motorised Motor Speed controllable external rotor motor, protection class IP44 (up to size 310L) or IP54 (from size 355), moisture-proof impregnation, thermal contacts mounted in motor winding. Electrical connection The motors are connected to a terminal box of protection class IP54, easily accessible after disassembly of the cowl. Installation All fans are delivered ready for installation and are packed in separate boxes or crates. We recommend the use of matching Wolter roof sockets. If other roof sockets are used, dimensions given in our catalogue should be followed to achieve proper sealing and avoid air-leakage. Fan performance curves The performance curves for these roof fans have been tested according to DIN 24 163. The curves indicate the static pressure increase . pst (static, free outlet) as a function of the volume flow. The reference air density is 1,2 kg/m³. Sound levels The sound data was measured according to DIN 45 635, part 38. The figures shown in the performance curves are the A-weighted sound power levels in dB(A). They are equal to the free outlet sound power level. The catalogue data is valid for RH-type fans. reduce listed noise levels by 2 dB(A). The free inlet sound power level can be calculated Sound reduction Socket silencer SD Insulated sound attenuation cowl LVS A socket silencer can be used instead of the flat roof socket for mounting the fan. It reduces the sound propagation on the suction side. When a socket silencer is used, additional pressure loss has to be taken into account. These can be found in the following diagram. Insulated sound attenuation cowl LVS In order to reduce the sound emissions radiated from the roof fan, the use of a RVS attenuation cowl is recommended. Compared to the non-attenuated roof fan cowl (RV) Insulated sound attenuation cowl LVS the RVS cowl has slightly higher pressure losses. شركة ارك ميك Arch Mech لاعمال التكييف المركزي concealed units Split units chilled water Supply and installation all types of duct sheet and insulation all types of outlets aluminum cladding concealed units Split units العنوان 46 عثمان ابن عفان ميدان الاسماعيلية مصر الجديدة القاهره تكييف مركزى سبليت شباك توريد تركيب صيانة موزع معتمد لجميع اجهزة التكييف صاج عزل فريون مواسير نحاس مخارج هواء ستائر هواء Air Outlets Ceiling Diffusers - Slot Diffusers - Swirl Diffusers - Jet Diffusers - Linear Grills - Air Louvers - Sand Trap Door Grill - Floor Grills - Gravity Shutter Grill Dampers Volume Control Dampers - Pressure Relief Dampers - Round Volume Dampers - Fire Dampers Duct Work Black Steel - Stainless Steel - Galvanized Duct - Aluminum Cladding Air Filters Pre Filters - Bag Filters - Synthetic Filters - Hepa Filters Services Balancing Test AIR DUCT - CHILLED WATER Insulation & Accessories Pipe Insulation - Flexible Duct - Duct insulation - Rockwool - Acoustic Lining - Flexible Duct Connector - Rigid Duct - Aluminum Foil Tape & Meatal Clamps - ,Duct Sealant Adhes
