Z-Class ARFF Vehicle
Modular 4×4-to-8×8 airport rescue and firefighting vehicle platform designed to exceed ICAO and NFPA standards across every category of international airport.
The Ziegler Z-Class is a purpose-engineered family of Airport Rescue and Fire Fighting (ARFF) vehicles built on a unified modular chassis platform, available in 4×4 (Z4), 6×6 (Z6), and 8×8 (Z8) all-wheel-drive configurations. Each variant shares the same Z-Cab AiR operator cabin — crash-tested to ECE R29-3, with 1.8 m standing height and extensive panoramic glazing — and the same CAN-BUS Z-Control operating system, so crew trained on one model can transition across the range without relearning core procedures.
Operationally, the platform serves the full spectrum of commercial and military aviation: the Z4 (up to 7,000 L water/foam, up to 700 HP) suits regional and Category 7–9 airports as a primary or supplementary unit; the Z6 (up to 12,500 L water/foam, 12,000–14,000 L range, 770 HP Scania V8) is configured for Category 9–10 international hubs; the Z8 (up to 19,000 L, twin 770 HP Scania engines, 0–80 km/h in under 18 seconds) is the flagship for the highest-category operations. All three meet or exceed ICAO Annex 14 airport category requirements and are available in Euro 3, 5, and 6 emission configurations.
Procurement engineers select the Z-Class for three distinguishing traits: first, the platform strategy — a single chassis family eliminates training fragmentation and simplifies spare-parts logistics across mixed fleets; second, Z-Attack compatibility — an optional articulated extinguishing arm (17 m reach) enables under-fuselage attack on widebody aircraft without manual crew exposure; third, proven pump integration — Ziegler's own FPN 10-series fire pumps and ZT-series roof turrets (up to 8,000 L/min at 10 bar) are built and tested as a complete system, not assembled from third-party components.
For GCC airport operators, the Z-Class addresses ramp conditions that stress standard vehicles: high ambient temperatures, extended taxiway distances, and the regular presence of A380, B777X, and ultra-long-range widebody aircraft that demand Category 9–10 response capacity. The single-tyre axle design optimises runway traction and braking on hot-mix asphalt.

Use cases.
- ›Primary ARFF response at Category 9–10 international airports handling widebody traffic (A380, B777X, B747)
- ›Supplementary or sole ARFF provision at Category 7–9 regional airports using the compact Z4
- ›Military and dual-use airfields requiring high-capacity foam attack on fast-jet or cargo aircraft
- ›Mixed-fleet airport fire services standardising on one chassis family to reduce spares inventory and crew training overhead
- ›Retrofit of existing airport fire stations where Z-Attack arm integration enables under-fuselage penetration without expanding crew numbers
- ›Hot-climate high-utilisation operations (GCC, tropical hubs) where single-tyre axles, high-spec disc brakes, and Euro 5/6 powertrains are mandatory or preferred
