New Zealand's
Largest Air-Vacuum Fleet

13 identical RSP ESE 6 suction excavators. One consistent standard, nationwide. Operated to documented SOPs and an internal competency standard that exceeds New Zealand regulatory requirements.

OUR FLEET

AirVac operates New Zealand's largest air vacuum excavation fleet: 13 identical RSP ESE 6 units. Because every unit is the same machine, with the same German engineering, capability, and operating standard, our clients get the same result on every job,

Proven On Site

Air vacuum excavation does the work of a hand digging crew in a fraction of the time and exposes live services without the strike risk of a mechanical excavator. That combination of speed and safety is why councils, utilities and Tier 1 contractors specify AirVac for work that cannot go wrong.

Zone 1

The Fan

The benchmark's #1 feature area — suction power.

43,000 m³/h suction — powerful double-fan airflow lifts heavy, wet and compacted ground.
Up to 55,000 Pa vacuum — sustained vacuum keeps the dig moving through demanding material.

Zone 2

The Boom / Hose Carrier

The benchmark's most-emphasised selling point — safe-distance excavation.

150 m reach — extendable suction digs up to 150 metres from the truck, without moving the vehicle.
6 m articulated boom, 180° — the operator excavates from a safe distance without repositioning.

Zone 3

The Suction Hose & Dig Point

250 mm suction hose — clears large debris and rocks without clogging.
Pneumatic excavation — breaks ground without a blade, so live services are exposed safely.
45 m vertical lift — removes material from banks, slopes and shafts.

Zone 4

The Spoil Container

Air, not water — dry, reusable spoil; no slurry and no liquid-waste disposal.
6 m³ capacity — right-sized for New Zealand site access, with ample capacity between off-loads.

Zone 5

Filtration

Self-cleaning filtration — 40 cartridge filters keep suction at full strength all day

Zone 6

The Cab / Operator

Competent operators — every operator assessed against an internal competency standard before working unsupervised.
Scania R500 8×4 — strong, stable and site-capable.

Indicative Excavation Rates

Material	m3 per hour	Time per m3
Sandy Soil	10	6 min
Muddy soil, gravel, crushed rock	6	10 min
Moderately heavy soil with buried cables and pipes	4	15 min
Wet heavy soil o clay	3	20 min
Dry heavy soil	2.5	24 min
Heavy soil with buried cables & pipes	1.67	36 min
The same heavy soil - excavated by hand	0.25	4 hours

Indicative industry rates; actual performance varies with ground and site conditions. On ground packed with live services, the slower rates are deliberate — careful, controlled exposure is what prevents strikes. Air vacuum excavation trades a little speed for the certainty that your cables and pipes stay intact.
