FG dust filter elements for Waiweldai systems: Quality doesn't have to be expensive
Operators of Waiweldai dust extraction systems are familiar with the issue: OEM filters are often expensive and not always available at short notice. EcoParts AIR from Filtration Group offers an economical and technically equivalent alternative—available from FILCOM.
What is EcoParts AIR?
EcoParts AIR is the replacement filter range from Filtration Group, the company that incorporated the former MAHLE Industrial Filtration division. These filter elements are manufactured to the company's established quality standards and are specifically designed as alternatives to the original dust filter elements used in the Waiweldai WW series.
Their function: to reliably reduce contaminants to the required purity level, prevent the ingress of ambient dirt, and ensure consistent process conditions throughout their service life—for efficient and safe system operation.
Compatibility via a matching adapter
To ensure that EcoParts AIR elements fit into existing Waiweldai systems, a special adapter with a RD 78x5 round thread and seal is used. This adapter is only ordered once – with the initial order of a WW-LF filter element – and then remains permanently in the filter system. For each subsequent filter change, only the actual filter element is required.
Two adapter variants are available:
- WW Series V4A adapter – made of stainless steel, for use in food applications
- WW Series EVZK adapter – galvanized, for non-food applications

FOOD and non-food: the right element for every requirement
FOOD versions are tailored to the specific hygiene requirements of the food and pharmaceutical industries. They feature V4A stainless steel end plates and iFix pleat stabilization, which gives the filter medium high dimensional stability.
Non-food versions are designed for industrial dust collection processes, such as in the plastics and building materials processing industries or bulk material handling. In these versions, the pleated filter packs are stabilized with bands.
Both versions share the following characteristics: They are electrostatically dissipative, installed on the raw gas side, and have an airflow from the outside in.
Two filter media for different applications
Depending on the application, two proven filter media are available:
| Filter medium | Filter class | Particularly suitable for |
|---|---|---|
| Polyester fleece with ePTFE membrane (Ti 07) | E10 | Very fine dusts, including sticky ones, thanks to effective cleaning via surface filtration |
| Aluminum-coated polyester fleece (Ti 08) | F8 | Cost-effective standard applications |
Both media meet dust class M requirements according to DIN EN 60335-2-69 and are also electrostatically dissipative.
