Hauni KDF-2 Cigarette Filter Machine: What Makes It the Right Choice for Mid-Scale Production

Filter quality is a silent differentiator in cigarette manufacturing. Smokers notice draw resistance, consistency and feel — but they rarely know whether those attributes were determined at the maker or at the filter rod machine two stages earlier. For manufacturers producing at small to medium volumes, the Hauni KDF-2 cigarette filter manufacturing machine is one of the most capable and appropriately scaled options available on the market today.

What Is the Hauni KDF-2?

The KDF-2 is a filter rod making machine produced by HAUNI — part of the Körber Technologies group and one of the most respected names in tobacco machinery engineering. The KDF-2 is the higher-output sibling of the Hauni KDF-1, designed to serve manufacturers who have outgrown entry-level filter production capacity but do not yet require the throughput of large-scale industrial filter lines.

It processes acetate tow — the primary raw material for conventional cigarette filters — into uniform filter rods ready for attachment to cigarette making machines. The tow opener system integrated with the KDF-2 (the HCF80 Auto Tray Filler) ensures consistent tow preparation and automated output handling, reducing operator intervention and improving run continuity.

Key Technical Specifications

  • Production Speed: 400 metres per minute (acetate tow)
  • Filter Circumference Range: 16.8mm – 28.1mm
  • Filter Length Range: 64mm – 150mm
  • Control System: Siemens or Beckhoff PLC
  • Servo System: Lenze or Beckhoff
  • Power Consumption: KDF-2: 40kW / HCF80: 15kW
  • Machine Weight: 6,500 kg

The circumference range of 16.8mm to 28.1mm covers standard, slim and super-slim filter formats, giving manufacturers the flexibility to produce across multiple product lines without requiring a separate machine for each diameter. The length range of 64mm to 150mm is similarly broad — accommodating everything from short filters for compact cigarette formats to extended filters for premium product lines.

KDF-2 vs KDF-1 — Understanding the Difference

The choice between the KDF-1 and KDF-2 comes down to production volume and format flexibility. The KDF-1 is purpose-built for smaller-scale operations and lower throughput requirements. The KDF-2 delivers a step-change in output capacity — at 400 metres per minute, it produces significantly more filter rod per shift than the KDF-1, making it the appropriate choice once a manufacturer’s daily filter demand outpaces what the smaller machine can supply.

That said, the KDF-2 is not simply a faster KDF-1. The integration of the HCF80 Auto Tray Filler adds automated output collection, reducing the manual handling of filter rods and improving traceability between the filter making stage and the cigarette filter making machine attachment process.

PLC and Servo Control — Why It Matters

The KDF-2’s Siemens or Beckhoff PLC control system provides precise process management across the full filter making cycle — from tow feed rate to rod cutting and output collection. The Lenze or Beckhoff servo system handles motion control with the accuracy required to maintain consistent rod density and length at 400 metres per minute. At this speed, even minor fluctuations in servo response translate into measurable variation in filter draw resistance — a parameter that defines finished cigarette quality as much as the tobacco itself.

Manufacturers who have previously run machines with older relay-based control systems often report that the transition to PLC-controlled filter making eliminates an entire category of quality variation that had previously been attributed incorrectly to the cigarette maker or the tobacco blend.

Who Should Choose the KDF-2?

The KDF-2 suits manufacturers running mid-scale cigarette production lines — typically those operating machines in the 3,000–6,000 CPM range, such as the Mark 9 MAX S or similar. At these production speeds, a single KDF-2 typically provides sufficient filter rod supply to keep the cigarette maker running without buffer stock constraints.

It is also a strong choice for manufacturers who produce multiple cigarette formats — slim, standard and king-size — from a single production facility, given the KDF-2’s wide circumference and length range. Format changes are achievable without significant downtime, which is a meaningful operational advantage for manufacturers serving diverse or export markets.

Maintenance and Spare Parts Availability

HAUNI’s engineering reputation extends to the serviceability of its machines. The KDF-2 is designed with maintenance access in mind, and the use of established PLC and servo brands (Siemens, Beckhoff, Lenze) means that control system components are available globally without relying on proprietary supply chains. Hauni spare parts for the KDF series are available through established machinery suppliers, ensuring that maintenance intervals do not translate into extended downtime.
