Industrial filters from Venti Oelde prove their worth every day in numerous industrial sectors such as in mineral processing, metalworking & metal processing, in recycling as well as in the fibre and wood industries. Our filters clean unwanted dust from air and process gases. They are very versatile and can be used for flow rates from 1,000 to over 1,000,000 m³/h and for dust quantities up to 1,000 g/Nm³.

Venti Oelde offers a single- or double-row filter, depending upon the amount of air, the amount of dust it carries and upon the space available. All filters can be used as suction and as pressure filters. The double-row designs are arranged with a centrally located inlet corridor for the unfiltered gas.

The gas to be filtered is fed to the outside of the filter bags in Venti Oelde’s industrial filters. The bags are intensively cleaned with pulses of compressed air during normal operation, synchronised to the operation in progress. The filters meet all of the requirements which can be placed on a modern filter system:

  • high flow rate through the filter media
  • a long service life for the filterbags
  • compact construction, low space requirements and adjustable filter height
  • cost-effective operation – for example, by controlling the timing of the compressed-air cleaning and the air pressure via the pressure difference across the filter
  • best filter quality and highly efficient bag cleaning resulting in low residual dust content and minimum pressure loss

As required, we make our industrial filters in galvanised, painted or stainless steel, with a minimum wall thickness of 3 millimetres for the housing. They are suitable for use both indoors and out.

We make the filters using sophisticated modular technology consisting of bent and bolted wall components. If minimum leakage is required, we can also seal the housing by welding from the inside. The filters are available in a range of heights and are designed for differing bag lengths and varying pressure levels.

The separated material is collected in the hopper and is discharged via a trough worm conveyor and rotary airlock or via double pendulum flaps. Larger quantities of material are taken away pneumatically via a transport duct. If only a small amount of dust arises, it can be discharged into bins or containers beneath the outlet.

For complex requirements, Venti Oelde offers very practical filter solutions. They are functional, reliable and have a long life. They are very efficient. And they are commercially cost-effective.

On request, Venti Oelde can supply plants on a turnkey basis. This means that we will take care of all components from the point of extraction right through to the exhaust gas stack, including the control system.

Venti Oelde also offers a PowerAirTube Reverse air filter with a combined pressure pulse reverse air cleaning process. Cleaning the filter bags with process air prevents the formation of condensation. Centrifugal material pre­separation is produced by the tangential inlet and the optimized filter bag arrangement. Stress is, therefore, reduced in the filter zone. The fan, integrated in the filter head, provides extraction and reverse air cleaning.

This filter offers following advantages:

  • Simple installation and commissioning (Plug and play)
  • Ease of relocation (Drag and drop)
  • Pressure shock resistance >2bar
  • Effective material pre-separation
  • Efficient and material-friendly bag cleaning
  • Compressed-air connection not required
  • Optimization of energy
