Fan is a device that circulates air. Fans have 3 major Duty include: suck air, blow air or circulate air.Fans are divided into the following categories according to the air flow direction relative to the fan axis:1-Axial fan 2-Centrifugal fan
Fans main accessories are the impeller and the Housing, which are the most important components. Include components whose fan proper functioning depends on their proper design and selection. One of the most important component is electric motor but other sources of power may be used, such as hydraulic motors, handcranks, and internal combustion engines, Shaft, bearing and power transfer system are the last component.
The power transfer system of the electric motor to the impeller in the fans is generally done in three ways:
Direct Drive, In this type of connection, the shaft of the electric motor is connected directly to the impeller.Belt Drive Connection, In this type, power is transmitted from the electric motor to the fan impeller by pulleys and belts. In this system, the bearing and the shaft diameter play an important role in power transmission.
Coupling connection, In this connection, which has many different types, the shaft of the electric motor is coupled with a set of shafts and bearings that are connected to the fan impeller.
Which brands Golden Hermez can supply?
Rosenberg Centrifugal fans backward curved Rosenberg Fans
The high efficiency centrifugal fans have been developed especially for modern ventilation and air conditioning applications and are ideal for the movement of air and light aggressive gas and vapours. The designation of size corresponds to the outside diameter of the impeller.The casing of the high efficiency centrifugal fans are made of galvanized sheet steel and the side parts of the scroll is assembled with the spirally shaped guide plate through a standing seam.
Rosenberg Axial fans (Type: ANDB)Rosenberg Fans
Rosenberg High efficiency axial fans are used wherever large air volumes must be conveyed against low up to medium pressure. High efficiency axial fans with square inlet cone are used for ventilating restaurants, gymnasiums, conference rooms, workshops, ware-houses, swimming pools and greenhouses. High efficiency axial fans with double flange ring are used in duct systems for air conditioning, cooling and drying applications.
Axial Rosenberg fan (ANDB) have flow rates up to 80,000 m³/h and pressure rates up to 1.200 Pa.
QG030-148/12Ebmpapst Tangential Blowers
The tangential flow principle is suitable for an extremely wide variety of applications that require an air supply over a wide surface. The very flat design of our products, and the resulting ease of integration, even into tight installation situations, is a result of the mostly small ratio of the shaft diameter to the shaft length. The large intake and discharge cross-section allows a high air flow at low flow rates. ebm-papst tangential blowers also feature a long thrust range and very low noise levels.
DECENTRALISED VENTILATION SYSTEMS HORIZONTAL: FSL-B-ZAB+SEKTROX TECHNIK
TROX is a global leader in the development, production and sale of systems for the ventilation and air conditioning . With 19 production facilities, TROX is present in over 70 countries.
features of DECENTRALISED VENTILATION :
Acoustically optimised EC fans with low specific fan powers.
Plate heat exchanger for heat recovery , including bypass damper with electric actuator (open-close).
Motorised shut-off dampers.
Gorilla HVLSX70ELTA FANS
The Gorilla X range can save energy costs and increase productivity while respecting the environment. The X range of destratification fans are designed to be installed in the ceiling space to redistribute warm air towards floor level, where it’s needed most. The high volume, low speed (HVLS) fans generate a gentle, slow moving airstream which covers a large area even when they are installed in a very high ceiling.
Industrial fans Type: P4MNicotra Gebhardt
Nicotra Gebhardt was founded in the early sixties Italy.
The Fans are of state of the art design and comply with the requirements for health and safety of the EG Machinery Directive. This Fans offer a high level of operational safety and a high standard of quality which is guaranteed through a certified Quality Assurance System (ISO 9001). All fans leave the factory after being subjected to testing and are provided with a test seal.
