Reverse-flow bag filter W 45R

The "Reverse-flow" bag filter W 45R (filter classes G4 and M5) is ideal for separating water droplets and salt particles thanks to its drainage properties.

Dimensionally stable support frame construction for extremely high reliability

Allows for installation on the fresh air side in combination with downstream filters when airflow is from outside to inside

W 70X Secondary Separator

Proven in paint finishing technology for over 15 years
Developed in cooperation with paint booth manufacturers specifically for the reliable separation of
overspray from 1K and 2K paint systems.
Suitable for primers, base coats, and clear coats

The W 70X secondary filter is an extremely robust bag filter designed specifically to meet the requirements of paint mist filtration.

The 3-layer, progressively structured high-performance filter media ensures longer filter service life and minimal pressure drop

Technical Specifications

No fiber breakage, as the filter media is made from break-resistant synthetic-organic fibers

The progressive structure of the filter media enables optimal retention of coarse and fine particles, ensuring uniform filter loading

Significantly extended service life due to high paint holding capacity

High operational reliability thanks to welded pockets and integrated spacers

Filter and frame are fully incinerable

Operation up to 5,000 m³/h per filter unit possible

Filter class (F7, EN 779:2012) ISO 16890 ePM10 85%
