Particulate filter unit ENTARON XD/MD

with filter cartridgecartridgeair

Overview
The ENTARON XD/MD from MANN+HUMMEL is a plastic air cleaner family with tangential raw air inlet designed for demanding industrial and mobile applications. The range carries forward proven features from Europiclon and NLG series while introducing design and functional improvements: ENTARON MD provides a single-stage variant with very low initial pressure drop, and ENTARON XD offers two-stage separation for heavy-dust environments.

Product benefits

• High engine protection through superior initial and final separation efficiencies
• Enhanced reliability thanks to filter elements with a new sealing system
• Weight reduction (~10%) versus conventional metal/hybrid solutions due to glass-fiber reinforced plastic housing
• Modular, variable system for flexible installation adaptation
• Tool-less element change enabled by comfort fasteners for rapid service

Powerful details
Robust housing
The ENTARON XD and MD housings are manufactured from glass-fiber reinforced plastic with reinforcement ribs to meet extreme mechanical requirements and improve corrosion resistance. The three-part housing has its main section welded to the raw air inlet to allow flexible inlet/bracket orientation. The clean air outlet is reinforced with a metal ring to permit hose clamp tightening torques up to 5 N·m, supporting secure ducting.

Smart details
Comfort fasteners include color-coded operating elements and snap-in noses to prevent interference during cover removal/installation. The housing integrates a connection for a service switch or indicator and provides integrated mounting options with through-holes (standard) and threaded inserts (on request) for fast and reliable installation.

High-performance filter elements
The ENTARON XD/MD elements are engineered for robustness and long service life:

• New sealing system for reliable element-to-housing sealing
• Reinforced plastic center tubes for element stability (not applicable to ENTARON XD/MD 40)
• New filter media with increased robustness and extended life
• Glue string technology fixes pleat tops to maintain element integrity in operation
• Safety element is threaded to the housing to prevent unintentional removal during service
• Optional main and secondary element variants available to meet different flow resistance and separation needs

Technical features

• Type of operation: Two-stage (ENTARON XD) / Single-stage (ENTARON MD) / Combination with external pre-separator (MD with DualSpin XT)
• Field of application: Mobile heavy-dust applications (XD) and stationary low-dust applications (MD)
• Volume flow range: 7–40 m³/min (XD), 20–40 m³/min (MD)
• Pre-separation efficiency: 87% (XD with dust discharge valve), up to 92% (XD with scavenging), 80% (MD with DualSpin XT), >89% (MD with scavenging)
• Final separation efficiency: >99.99% (XD), >99.97% (MD)
• Dust discharge: Dust discharge valve or scavenging options
• Installation: Vertical and horizontal installation possible (depends on dust discharge valve position)
• Service concept: Front access with comfort fasteners; tool-less element change
• Additional water ingress protection: ENTARON XD 14–28 on request, ENTARON XD 40 standard

Further product details

• Modular system allows flexible adaptation to installation constraints
• High pre-separation efficiency of ENTARON XD often eliminates the need for an external pre-separator in heavy-dust applications
• Available options for secondary elements and variants for different flow resistance / separation efficiency requirements
