A mixed-flow fan combines the advantages of axial fans with the characteristics of radial fans. Simply described, it is an axial fan with a fan wheel in radial format. This provides a cost-effective design, in duct or box design, with a stable fan curve and relatively high pressure. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials. The fans are usually supplied as a complete unit. Mixed-flow fans are usually used as ventilation fans. Typical applications are ventilation solutions in gyms, sports halls, warehouses, commercial kitchens, factories or airport terminals. Depending on requirements, the design of a mixed-flow fan can be completely adapted to the customer’s needs. With the right dimensioning and material selection, a mixed-flow fan will work problem-free for many years.

The wall fans we offer are direct-driven axial fans that are easily installed in walls or ceilings. The wall fans can be in 1-phase or 3-phase design. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials The fans are usually supplied as a complete unit, but we can also offer new impellers for existing wall fans.

In tough applications such as e.g. high temperatures or movement of corrosive gases, it is not always possible to mount a motor in the volume flow. The solution for this is the so-called bifurcated fan which is an axial fan where the air flow is divided in a tunnel, which means that the motor is not in the volume stream. It is thereby protected from possible harmful particles or high temperatures. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials. The fans are usually supplied as a complete unit.

Radial fans or centrifugal fans are a type of fan that uses centrifugal force to create a pressure increase and a volume flow. This type consists of a fan wheel that rotates in a snail-shaped cover. The flow enters the fan through an inlet placed axially with the fan wheel shaft and motor, and is then thrown out radially with the help of the force from the fan wheel. Unlike axial fans, the motor is not in the volume flow of radial fans. To change the performance and characteristics of centrifugal fans, different designs are used on the fan wheel. The strength of the centrifugal fan is its versatility. A radial fan can be designed to transport a variety of volume flows at a wide range of pressures. At higher flows and relatively low pressures, an axial fan may be a better option. Centrifugal fans are available in single and double suction versions.

Industrial Fans - Comprehensive production

With direct drive, V-belt drive or coupling drive. Industrial fans Fans are used in countless industrial plants. If the fan fails, the plant must be shutdown and production stopped. These fans are in operation around the clock, often under adverse conditions (heat, wear and aggressive media), in order to guarantee the production process. Our fans prove their reliability every day in the cement, glass, steel, wood or recycling industries, to name but a few examples. Our fans are used in the foodstuffs and chemical industries as well as in mushroom growing or agriculture. We offer you an individual technical solution adapted to the respective conditions which, in addition to function and reliability, also takes into account energy efficiency. In partnership-like cooperation with our customers, we develop economically sensible ventilation systems. Our range of services extends from planning, manufacturing, installation and commissioning to after-sales service. In addition to on-site balancing, we supply you with spare parts and also install them on request.

Repair or maintenance of fans. Repairs Fan impellers are often subject to high degrees of wear due to the solids in the conveying medium. Preventative maintenance helps to save costs, because a completely destroyed impeller can only be replaced by a new one. An impeller that is only partly damaged can easily be repaired and is comparable to a new impeller with regard to its subsequent service life. Naturally we also repair fans not made by us. Balancing and inspection of bearings The increasing demands on the performance, smooth running, weight, quality and life span of machines mean that increasing importance is also attached to mechanical vibrations. Balancing helps in most cases to eliminate the vibrations or at least to reduce them to an acceptable level. The fact that mechanical vibrations are not only unpleasant but also damaging is shown by a drastic shortening of the lifetime of gearboxes and roller bearings as well as the occurrence of fatigue fractures or unacceptable noise. The diagnosis is imbalance or bearing damage. Both causes result in elaborate repair work. While the bearings can be exchanged by the user’s service technicians, external services are required for the balancing of a fan impeller, since a balancing machine and special know-how are needed for this. Rippert uses state-of-the-art balancing machines in accordance with DIN ISO 1940 for this. Stationary balancing Rotor size: max. DN 4,000 mm Rotor weight: max. 10,000 kg Measuring procedure: force measurement Balancing quality: Q 6.3* * other qualities on request On-site balancing In addition to stationary balancing in the factory, Rippert also offers on-site balancing. This saves elaborate disassembly and assembly work as well as time-consuming and, depending upon size of the impeller, expensive transport.

Rippert offers a multitude of accessories for fans. Accessories

For pressure ranges from 3,000 to 16,000 Pa. High-pressure fans The field of application of high-pressure fans extends over almost all branches of industry. Our high-pressure fans cover a pressure range from 3,000 to 16,000 Pa. Thanks to their simple and solid construction, these fans know how to convince. Whether they are used as a blower in an industrial washing machine or as a ventilation fan in a compost works, these machines perform every day.

For the transport of large solid particles with the conveying stream. Transport fans Fans can also be used for the transport of materials. A suitable blade shape and the employment of open impellers enable the transport of large solid particles with the conveying stream. Thanks to our large selection of impellers we can ensure the trouble-free flow of material. Apart from the wood industry, our clientele includes the plastics and paper industries.

For the conveying of explosive dusts or gases. Explosion-proof fans For the conveying of explosive dusts or gases, out fans are equipped with spark protection at the impeller inlet. Both the shaft seal and the drive train comply with the regulations of the European ATEX directives.

For the conveying of gaseous materials. Gas-tight fans If the conveying medium of a fan must not be allowed to penetrate to the outside (e.g. gases that are harmful to health), our fans are equipped with a multi-chamber labyrinth seal on the shaft gland. Depending on requirements, the seals are provided with a sealing gas connection or a grease seal. Under certain circumstances the sealing gas can also be connected to the suction side of the fan. Naturally the flange connections are sealed accordingly and the fan housing is welded gas-tight and tested.

Wear-protected industrial fans. Wear-protected industrial fans Solids are often transported with the air that are very abrasive (e.g. corundum, sand, quartz, wood). These solids lead to considerable wear, in particular of the fan impeller. Progressive loss of material takes place, which can lead to machine failure. By means of specific measures to prevent wear, the service life of the fan can be extended. In addition to a suitable blade geometry, austenitic manganese steels and build-up welds can be used to counteract impact and sliding wear.

Serie LPE HELICAL FANS FOR WALL The LPE serie’s fans, present constructive characteristics that allow both the utilization in the industrial applications and the installations in the tertiary environments (workshops, stores, breedings, glasshouses) where there is the real necessity of the employment of a fan with easy installation, low consumptions, and reduced noise pressure levels.

EFKC filtered shelter fans are used to supply fresh air. It can be used in two different positions thanks to the by-pass cell. Normally, the air is sent indoors only by passing through the G4 Filter. When we want the air to be cleaned, it is passed through the G4 cassette filter, active carbon cassette filter and M6 cassette filter, which is more sensitive than the coarse filter, and sent indoors. By-pass air dams are made with a sliding system.

These fans, which are used in the ventilation of closed environments, can operate without problems with their high performance, they can operate even at high temperatures since the engine is outside of the air flow.
