Cartridge filter unit ENTARON XD/MD

particulatewith filter cartridgeair

Overview
The MANN+HUMMEL ENTARON XD and ENTARON MD series are plastic-housed air cleaners engineered for demanding industrial and mobile applications. ENTARON XD is a two-stage unit with a tangential raw-air inlet; ENTARON MD is a single-stage unit optimized for low initial pressure drop.

Key product narrative
Designed for heavy-duty and variable-duty environments, the ENTARON family extends proven separation performance with a modular plastic design that reduces weight and simplifies service while maintaining high separation efficiencies.

Product benefits

• High engine protection through elevated initial and final separation efficiencies
• Improved reliability via filter elements with an advanced sealing system
• Approx. 10% weight reduction versus conventional metal or hybrid solutions
• Modular design for flexible configuration and adaptation to different installations
• Tool-less element replacement using color-coded comfort fasteners for fast service

Powerful details
Robust housing
Housings are manufactured from glass-fiber-reinforced plastic with reinforcement ribs. The three-part design is welded to the tangential raw air inlet to secure orientation and integrated brackets. The clean-air outlet includes a metal reinforcement ring permitting hose-clamp torque up to 5 N·m. High pre-separation efficiency of ENTARON XD makes it suitable for heavy dust loads and often removes the need for an external pre-separator.

Smart details
Comfort fasteners feature color-coded operating elements and snap-in noses that lock during cover removal or fitting. The housing integrates a connection for a service switch/indicator and supports mounting with through-holes (standard) or threaded inserts (on request).

High-performance filter elements

• New sealing system for reliable element-to-housing sealing
• Robust plastic center tubes to reinforce elements (not for ENTARON XD/MD 40)
• More robust filter media for extended service life
• Glue-string pleat fixation for stability under varying conditions
• Safety element threaded to housing to prevent unintentional removal during service
• Additional main and secondary element variants available as options

Technical features

• Type of operation: ENTARON XD — two-stage; ENTARON MD — single-stage; ENTARON MD 40 with DualSpin XT — combination with external pre-separator
• Field of application: XD — mobile equipment with very high dust load (construction machines, harvesters, mobile cranes, compressors); MD — stationary machines, gensets, low dust-load applications; DualSpin versions — extreme dust load applications
• Volume flow range: ENTARON XD 7–40 m³/min; ENTARON MD 20–40 m³/min
• Pre-separation efficiency: up to 92% (with scavenging) for XD; ~87% (with dust discharge valve)
• Final separation efficiency: up to >99.99% depending on version
• Installation: vertical and horizontal possible depending on dust discharge valve position
• Service concept: front access with comfort fasteners; tool-less element change
• Water ingress protection: ENTARON XD 14–28 on request, XD 40 as standard
