The compact power pack

The IQORON VP range was developed especially for applications with medium to heavy dust loads. The compact and innovative two-stage air cleaner equipped with the new VarioPleat filter element is designed for applications with an output of 400 kW or more where installation space is tight. The unique concept enables a short air flow path to the engine. In comparison to similar solutions available on the market, the IQORON VP achieves up to 70 percent longer service life without scavenging.

  • High-performance VarioPleat filter element enables high power density


Powerful details

Improved separation performance

The performance of the IQORON VP is ideally suited for medium to heavy dust loads. Implementation of an updated multi-cyclone pre-separator allows the air cleaner an improvement in performance for non-scavenged applications. The IQORON VP can be installed with a dust discharge valve in horizontal and vertical installation positions without a decrease in performance. As an option, the IQORON VP is also available as a single-stage air cleaner (i.e. without multi-cyclone block pre-separator). In heavy dust environments similar to agricultural applications, the DualSpin XT pre-separator can be attached to the IQORON VP for improved handling of organic and fibrous dusts. When combined with scavenging this achieves excellent pre-separation efficiency. A special design of the guiding vanes considerably reduces pressure drop in the pre-separator. Generously dimensioned flow paths virtually exclude the possibility of air cleaner plugging.

The innovative design of the VarioPleat filter element enables variable pleat heights.

Variable element geometry

The unique VarioPleat filter element concept enables a particularly high power density for filter systems with an axial flow. Individual pleats within the filter can be optimized to the space available utilizing steps or curves to allow conformance to the available space. Tight installation spaces can now be fully utilized with the geometrical design freedom of the VarioPleat. As a result, the air cleaner can find application even when the installation requirements are complex. Innovation of the element manufacturing technology yields a lower pressure drop when compared to other filter element technologies. Clogging of the pleats by large debris is minimized by the stabilized structure of the element.

The VarioPleat element technology is used as standard in the IQORON VP range and also in custom designed solutions.

Flexible compact design

The modular design of the compact IQORON VP two-stage air cleaner allows easy adaption to a single-stage air cleaner and can therefore be flexibly adapted to complex applications. The special characteristics of the air cleaner make it very suitable for tight installation spaces with further advantages:

  • Slim, compact design for installation in complex installation spaces

  • Threaded inserts offer numerous mounting possibilities and simplify installation of the air cleaner

In comparison to similar solutions available on the market, the unique concept of the IQORON VP air cleaner achieves an increase in service life of up to 70 percent without scavenging.
