AirLift®

High-precision lightweight separator

The AirLift separates what previously could not be separated. Materials with very similar specific densities are its specialty. This air classifier also ensures maximum efficiency when used upstream of the NIR classifier.

  • Advantages
    • Higher efficiency than normal overband suction systems
    • Precise adjustment of ballistic trajectory, air speed and visibility
    • Purity levels up to over 99
    • Max. Flow rate 320 m³/h

Simple to integrate

Putting an end to nuisance

Air classifiers are a core element of systems for separating components of different weights contained in waste streams. Our AirLift vacuum air classifier is a particularly effective design.

The ultra-light separator enables sorting processes in which the specific weights and ballistic flight properties of the respective constituents differ only slightly. Applications include, for example, the recycling of PET bottles, where the valuable PET fraction can be cleaned with high efficiency and purity from light impurities such as labels made of PE film or paper. The AirLift also masters the great challenge of freeing biological waste from plastic contaminants outstandingly.

Innovationen im Detail

A windsifter system consisting of three components

Main component

AirLift®

The central element is a vacuum chamber that extracts ultra-light impurities from material streams.

AirWheel®

The rotating screening drum separates the separated material from the air stream.

SpeedCon®

The high-speed articulated conveyor belt, conveys the material at a speed of up to 4 m/s.

Stricter regulations require
sophisticated technologies

Ingenious technology down to the last detail

The entire AirLift system can be used as a subcomponent of a more comprehensive sorting system and is designed in such a way that it can also be easily retrofitted if required.

High reliability thanks to automatic opening of the entry and exit gates when material blockages are detected. The gate regulation also ensures exact adjustment of the passage height to the individual separation target thanks to its infinitely variable adjustability.

The AirLift uses the diametrical downflow principle in the stilling chamber to separate the different fractions even more accurately in a second stage. At the same time, the operating parameters can be precisely adjusted via the integrated target pressure control.

As upstream sorting, the AirLift is a popular addition to NIR machines. The removal of impurities ensures a significant improvement in NIR efficiency.

The easy-to-maintain AirWheel is a downstream unit of the AirLift. Here, the light fraction is removed from the air stream by means of a rotating screening drum. The remaining dust-air mixture can be fed to the air filter without any problems.
