Exhaust, filter and convey We make air work on your behalf

Your competent partner

Venti Oelde extraction, filter and conveying systems are used in almost all industries. They capture dust and solid particles from air and process gases, convey them and separate them. Among our core services are planning, manufacture and installation as well as the commissioning of our air handling systems, using a variety of separation systems. As a quality-certified, mediumsized enterprise, we always think ahead. We see ourselves as a company that produces long-term concepts using our skills to provide individually customised solutions. Thanks to many years of knowledge interchange with customers,...

Complete systems for successful projects Venti Oelde is a competent supplier of complete systems, with a comprehensive understanding of the sector and many years of experience in the market. We offer our customers consulting services and technology from a single source and provide assistance in every phase of your project. This avoids costly and timeconsuming interface problems. We always think beyond the current requirements by also taking our customer's future plans into account. This means that investments can be calculated on a long-term basis and that even subsequent extensions to a system...

Modular industrial filters for indoors and out Depending on requirements, Venti Oelde manufactures its industrial filters in galvanised, painted or in stainless-steel versions while always maintaining a minimum thickness of 3 mm for the walls of the housing. The extremely robust designs prove their worth on a daily basis in numerous industrial sectors, for example in the mineral processing industry, the wood industry, in metalworking and processing industries as well as in recycling. Industrial filters are built using a sophisticated modular technology consisting of bent and bolted wall components....

Our special versions are as different as the requirements: • For protection from the weather when changing filter bags, a penthouse is a good idea, especially for larger filter systems. • An additional empty chamber serves to calm the gas for large quantities of dust. Here, a large part of the dust will separate out. For suspended dust we use offline cleaning. • We construct pressureshock resistant filters with pressure venting conforming to VDI 3673 for the separation of flammable and explosive fine dusts. • Wear protection materials and wear protection plates, protect the endangered areas of...

Highly variable reverse air and pulse filters for the processing of light-density materials When filtering air containing bulky and/or fluffy fibrous material, other parameters apply than for conventional dust. The aim is to avoid dust collecting in the spaces between the filter bags to ensure a continuous discharge of the filtered dust as well as to maintain a constant pressure loss in the filter. Venti Oelde has developed special reverse air and pulse filters for the processing of light-density materials in the wood, fibre, textile and paper industries. They work with air volumes from 10,000...

We supply two versions of these filters: single or double row, in a parallel, two-chamber design. The modular construction of the reverse air filter makes the positioning and assembly of the filter very flexible. It is easy to extend this by adding units. Cleaning using reverse air or jet pulse, depending on the process, means that filter bags with a length of up to 5.4 m can be used. For reverse air filters, a mobile reverse air cleaning unit moves within the clean air plenum of the filter, from filter bag row to filter bag row. The control system, which depends on the pressure difference, reduces...

Needs-based round and cyclone filters with explosion protection As a centrifugal separator with a tangential inlet, these filters offer the greatest possible primary separation. Pressure is carefully applied to the filter bags. The round shape of the housing makes it very robust. Pressure-shock-resistance up to 10 bar has been proven via tests with water pressure. Use in areas at risk of explosion conforms to ATEX guidelines 94/9/EU. Pipelines with pressure relief baffles prevent the pressure wave from entering downstream equipment. The dust-laden air ducts can be decoupled with tested nonreturn...

Compact cartridge jet filters for almost all types of dust Cartridge jet filters are a special series of filters which ideally complement our comprehensive range of dry filters. Cartridge jet filters can be used for the separation of almost all free-flowing dusts. They are suitable for installation both indoors and out. The use of filter cartridges with a large filter surface in a very small space is what makes cartridge jet filters extremely compact. For many dusts, the high degree of separation provided by filter cartridges, enables the filtered air to be returned to the working areas. In combination...

The superior ROVAL pocket filter system for dry dust The ROVAL, oval bag filter range is a compact, spacesaving and extremely efficient pocket filter system for the separation of almost all dry, free-flowing dusts. The oval filter bags are installed horizontally in the dust-laden gas plenum. They are clamped and sealed against the slotted wall from the clean air side. The advantage of oval filter bags is that they keep their shape. Cleaning is supported by the vertical downflow to the bags. Short, powerful pressure pulses dislodge the dust cake from the filter surface. The pulses come from the...

By carefully matching up filter area, filter media and cleaning cycles, we achieve a high degree of dust extraction. All available textile filter media can be used. Protection measures can be integrated such as spark and fire extinguishing systems, as well as explosion venting, offering a high safety standard. Our ROVAL filters can be easily and quickly assembled on site, as they are factory pre-assembled, including the fitting of filter bags. Low filter resistance and the sparing use of compressed air reduce operating costs. Other plus points include the minimal maintenance requirements and...
