Air filter cartridge NLG

dustglass fiber-reinforced plasticplastic

Overview
The NLG series developed by MANN+HUMMEL is an economical, modular solution for intake-air filtration across multiple industrial applications. The series offers configurable lengths and diameters and three main variants to match dust load and installation constraints. NLG Pico is a single-stage design for low dust loads; NLG Piclon adds a tangential pre-separation stage for medium dust loads; NLG Pico with DualSpin pairs the Pico element with an external cyclone pre-separator for high dust loads.

Variants

• NLG Pico: Single-stage air cleaner for low dust-load applications.
• NLG Piclon: Two-stage air cleaner with tangential pre-separation for medium dust-load applications.
• NLG Pico with DualSpin: Combination air cleaner (single-stage element) with external cyclone pre-separator for high dust-load applications.

Technical features

• Type of operation: Single-stage (NLG Pico) / Two-stage (NLG Piclon) / Combination with external pre-separator (NLG Pico with DualSpin).
• Field of application: From light to high dust loads — commercial vehicles, compressors, marine engines, construction and agricultural machines.
• Volume flow range: 10–45 m³/min (NLG Pico), 10–40 m³/min (NLG Piclon), 18–50 m³/min (NLG Pico with DualSpin).
• Pre-separator: None (Pico) / Tangential (Piclon) / Cyclone (DualSpin).
• Pre-separation efficiency with dust valve: - / 75 % / 80 % (Pico / Piclon / DualSpin as applicable).
• Pre-separation efficiency with scavenging (5 %): - / >80 % / >84 %.
• Final separation efficiency: >99.99 % (Pico, Piclon) / >99.97 % (Pico with DualSpin).
• Dust discharge: Optional dust discharge valve (Piclon, DualSpin) with optional scavenging.
• Installation: Vertical and horizontal installation possible; orientation may depend on dust discharge valve position.
• Service concept: Front servicing with standard fasteners; tool-less element change with standard wire clamp fasteners.
• Additional protection against water ingress: Optional.

Product benefits

• Housing: corrosion-free, plastic reinforced with glass fiber for long service life in harsh environments.
• Filter elements: metal-free and fully incinerable for environmentally friendly disposal.
• Flexible inlet positions and modular sizes for easy adaptation to different equipment.
• Integrated threaded inserts for rapid initial installation on vehicles or machines.
• Standard fasteners enable quick filter element replacement without special tools.

Powerful details
Modular system for excellent flexibility
The NLG modular design provides four diameters combinable with three housing lengths to create 12 base variants. This allows adaptation to space constraints and dust-load requirements: short housings for standard use, longer housings and elements for increased service intervals. Standard duct connections and a simple bracket mounting facilitate retrofit and replacement.

Perfect for extreme conditions
The DualSpin pre-separator option is tailored for high dust and harvesting conditions. It delivers pre-separation efficiency above 84 % while reducing pressure drop compared to the tangential Piclon design. The antistatic pre-separator housing and large flow cross-sections minimise clogging and are suitable for organic particle separation. Guiding vane inserts cover flow rates from 18 to 50 m³/min.
