Vetter S.Tec Lifting Bags — 12 bar

Next-generation 12-bar lifting bags — 2.5 cm insertion height, up to 102 tonnes. More powerful than conventional 8-bar bags of the same size.

Vetter Feuerwehrtechnik GmbH — Germany

Vetter has manufactured pneumatic rescue bags since 1958. S.Tec lifting bags operate at 12 bar — significantly outperforming conventional 8-bar bags of the same size. Each bag is individually pressure-tested and CE marked under EN 13204.

The S.Tec series is Vetter's next-generation high-pressure lifting bag. At 12 bar working pressure with only 2.5 cm insertion height, S.Tec bags deliver exceptional lifting force even in the most restricted access scenarios. Available in 14 sizes — from 1 tonne compact bags to 102 tonne heavy rescue bags — square and rectangular options.

S-TEC Technology — Why 12 Bar Changes Everything

The conventional rescue airbag industry standardised on 8 bar working pressure for decades. Vetter's S-TEC series increased that to 12 bar — a 50% increase in working pressure. The practical result is that an S-TEC bag delivers significantly more lifting force from the same physical footprint as an equivalent 8-bar bag. The V7 at 280 × 280 mm and just 2 kg generates 7.5 T of lifting force. The V102 at 950 × 950 mm and 23 kg generates 101.6 T.

The 2.5 cm insertion height is one of the lowest in the category — the flat, uninflated bag profile lets it slide under vehicles, structural elements and machinery where even slightly thicker equipment would not fit. This combination of low profile and high force per unit area makes the S-TEC the industry benchmark for vehicle extrication rescue bags.

12 bar working pressure
50% more pressure than 8-bar bags. More lifting force from the same size bag.
2.5 cm insertion height
Flat uninflated profile slides under vehicles with near-zero ground clearance.

Standardised across all S-TEC sizes — one controller operates any bag in the range.

Selecting the right S-TEC size

S-TEC bags are specified by their maximum capacity at the start of inflation. As the bag extends, capacity falls — a V50 that generates 50.1 T at low height generates less as it expands. For most vehicle extrication scenarios, size your bag to the maximum load weight at the height you expect to be working. If you need to lift a 20 T vehicle to 20 cm, a V26 (25.9 T, 27 cm max) is the appropriate choice. If you need a safety margin or will operate at higher extension, the next size up is recommended. Contact us and we can advise on the right size for your specific fleet and operational scenarios.

Frequently Asked Questions

What does the V number in S-TEC model names mean?

The V number represents the maximum lifting capacity in tonnes at the start of inflation. V7 lifts up to 7.5 T, V50 up to 50.1 T, V102 up to 101.6 T. This is the peak capacity at low extension. Capacity decreases as the bag extends to full height — always confirm the working load at the expected operating height, not just the headline capacity figure.

How does the S-TEC differ from older 8-bar rescue bags?

S-TEC bags operate at 12 bar — 50% higher than the 8-bar industry standard. This means significantly more lifting force from the same size bag. An S-TEC V20 at 440 × 440 mm delivers 20.2 T of lift — equivalent performance would require a substantially larger 8-bar bag. The higher pressure also means the S-TEC can work through a greater stroke, often delivering better usable height alongside better force.

What insertion height do S-TEC bags require?

All S-TEC bags have a 2.5 cm (25 mm) insertion height when uninflated. This allows them to be slid under vehicles, machinery, or structural elements where ground clearance is very limited. A single standard bag can typically be inserted under a vehicle that has settled after a collision with as little as 3–4 cm of clearance between the vehicle and the ground surface.

Can S-TEC bags be used in tandem?

Yes. Two S-TEC bags of the same model can be used side by side, controlled by a single 2-circuit Vetter controller. Each circuit controls one bag independently, allowing the operator to balance the lift. When two V50 bags are used in tandem, the combined starting capacity is approximately 100 T. A 4-circuit controller allows two independent tandem pairs for asymmetric or multi-point lifts.

What air supply is needed for S-TEC bags?

S-TEC bags require 12 bar compressed air. Standard fire service breathing air cylinders (200 or 300 bar) supply this through a Vetter pressure regulator. Vehicle air compressor connections and dedicated rescue compressors are also suitable. All bags connect via the standardised NW 7.2 quick-connect fitting — compatible with all Vetter controllers and hose sets.

Do you supply Vetter S-TEC bags to Egypt and across Africa?

Yes. Fire and Rescue Tech is an authorised Vetter distributor for Egypt, the Middle East and Africa. We supply the complete S-TEC range including all 14 sizes, together with compatible controllers, hoses, pressure guards and carry cases. We handle import documentation, customs clearance and local delivery across the region.
