Description
The NLG air cleaner family offers a modular range of air filtration solutions designed for industrial engines and equipment operating under different dust conditions.
The range includes three configurations — NLG Pico, NLG Piclon and NLG DualSpin — providing different levels of air pre-separation to meet specific application requirements.
From low-dust environments to demanding operating conditions with high dust concentrations, the NLG family allows OEM manufacturers to select the most suitable filtration configuration based on airflow requirements, dust exposure and maintenance needs.
-
Modular Design: Four air cleaner diameters and three housing lengths provide 12 basic configurations to accommodate different installation and filtration requirements.
-
Application-Specific Filtration: Three configurations designed for low, medium and high dust loads, with different pre-separation solutions.
-
Robust, Corrosion-Resistant Housing: Glass-fiber-reinforced plastic construction provides durability and resistance to corrosion.
-
Easy Installation: Variable inlet positions and integrated threaded inserts simplify adaptation to different equipment configurations.
-
Tool-Free Maintenance: Standard wire clamp fasteners allow quick access to the filter element without tools.
-
Environmentally Conscious Design: Metal-free, fully incinerable filter elements support economical disposal, while Cr(VI)-free components are used throughout the range.
-
Flexible Filtration Performance: Different housing lengths and filter element configurations allow the system to be adapted to varying dust loads and airflow requirements.
The NLG Piclon is a two-stage air cleaner designed for industrial engines and equipment operating under medium dust loads, particularly in construction and agricultural machinery.
With a volume flow range of 10 to 40 m³/min, the system incorporates an integrated tangential cyclone pre-separator that generates rotating airflow to separate dust particles before they reach the main filter element.
The pre-separation system achieves 75% efficiency with a dust discharge valve and over 80% with 5% scavenging, helping reduce the dust load on the main filter and support efficient operation in moderately dusty environments.
The NLG Piclon combines economical operation with a modular design, offering different housing lengths and filter element configurations to accommodate varying airflow and installation requirements. Its robust glass-fiber-reinforced plastic housing and front-access servicing concept simplify installation and maintenance.
The system is suitable for vertical or horizontal installation, depending on the position of the dust discharge valve, which must always face downwards.
The NLG Piclon operates continuously at temperatures from -40 °C to +80 °C, with short-term exposure up to +100 °C.
