PRODUCT INFO

High Pressure Inflatable Arches

Airtight inflatable arches, also called sealed-air or high-pressure arches, are inflated once at the start of your event and hold firm for days. There is no blower, no power supply and no noise, so they suit venues without a power point, noise-sensitive events and multi-day activations.

We make airtight arches in two materials. PVC tarpaulin is the robust, hard-wearing option, with a direct full-colour print or velcro banners so you can swap sponsor logos and START or FINISH messaging between events. TPU is better when your design changes entirely. I has a thermoplastic bladder covered with an interchangeable polyester skin, so you buy one frame and replace the skin for each event.

 

Both materials inflate and deflate easily, stand up to repeated use, and can be repaired if punctured. We make airtight arches in a range of shapes and sizes, so contact us about what your event needs.

PVC or TPU: Which Airtight Arch Suits You?

Not all airtight arches are built the same way, and the material yours is made from shapes how long it lasts, how easily it travels, how the branding holds up in the sun, and whether the whole structure needs replacing when you want a new look.

We build airtight arches in two construction types: PVC tarpaulin, and a Thermoplastic Polyurethane (TPU) frame with an interchangeable polyester skin. Both use sealed-air technology, so you inflate the arch once and it holds firm for days with no blower, no power lead and no fan noise. The difference is what each material does on-site, and how its branding system works.

PVC tarpaulin is the proven, heavier-duty option: a tough, dense fabric that wears well under repeat use and keeps the entry cost lower. TPU is a lighter, more advanced polymer that stays flexible in the cold, handles UV better over time, and forms the frame of a modular system where the printed outer skin is fully replaceable, so a rebrand means a new skin, not a new arch. Which one suits you comes down to how often you move the arch, how frequently your branding changes, and the conditions you run in.

GUIDE

How to Install

01

UNPACK & POSITION
Unfurl the arch in its final position and locate the zippers on each side.

02

ADD BALLAST
Open the side zippers and insert a sandbag into each leg for a stable base.

03

CONNECT THE PUMP
Find the inlet valve, connect the supplied pump, and switch it on.

04

INFLATE FIRM
Fill until the arch is rock-hard. Once full, air releases through the overfill valve.

05

SEAL IT
Switch off the pump and close the inlet valve securely. The arch stays firm for days, no power needed.

06

ANCHOR DOWN
Secure the arch with ropes and weights as ballast before the event begins.

THE GOLDEN RULE
When it comes to weighting
an arch, too much is never enough.

FAQs

An inflatable arch is a large, eye-catching, custom-branded structure used at fun runs, marathons, triathlons, festivals, council events, store openings, and promotional activations. Inflatable arches are available in various shapes, sizes, and colours and can be printed with full-colour branding, event names, and sponsor logos. They are one of the most effective ways to create a start/finish line or a high-visibility entry point at events across Australia.

A Sealed Air arch contains a high-pressure TPU bladder that holds air tightly once the valve is sealed. Similar to a high-quality inflatable raft, it maintains its rigidity for days without needing an external air supply.

Only during setup. A sealed-air (airtight) arch needs power just to inflate it once. After the valve is sealed, it holds firm for days with no blower, no power and no noise.

Yes. Every airtight arch includes:

  • Heavy-duty D-rings
  • Tie-down ropes
  • Ground spikes
  • An electric pump for inflation
  • A carry bag for transport and storage

Popular arch shapes include:

  • Semi-Round Arch
  • Semi-Square (90°) Arch
  • Angled Arch

Custom shapes and profile designs are also available, ideal for brand activations, sporting events, and high-pressure sealed models.

Absolutely. Your inflatable arch can be fully customised, including:

  • Size and footprint
  • Colours
  • Sponsor or event branding
  • Removable Velcro banners
  • Additional anchor points
  • Custom shapes or profiles

Typical construction includes:

  • Outer skin: 400D Dacron or Oxford fabric
  • Internal bladder (Sealed models): High-pressure TPU
  • Reinforced seams and industrial zippers designed for Australian conditions

Airtight arches are built either as robust PVC tarpaulin (direct-printed or fitted with velcro banners) or as a TPU frame with a replaceable polyester skin.

Yes. When properly anchored using ropes, D-rings, and ground stakes, inflatable arches perform well in moderate wind. As with all event structures, wind conditions should be monitored onsite for safety.

They are suitable for a wide range of Australian events, including:

  • Race start/finish lines
  • Fun runs, marathons, triathlons
  • Council festivals and community events
  • Retail store openings
  • Corporate activations
  • Trade shows and exhibitions
  • School and sporting carnivals
  • Charity fundraisers
  • Parades and promotional events

Yes. Most arches can be installed by 1-2 people:

  1. Position the arch
  2. Connect the blower or pump
  3. Inflate
  4. Anchor using ropes and ground spikes

Very easy. Open the valve to release the air, then roll or fold the arch into the supplied carry bag.

Yes. Minor punctures or wear can be repaired onsite. For larger damage, a technician can perform a more extensive repair. High-quality materials are designed for long-term durability.

No. A suitable electric pump is included with all Sealed Air arches.

With proper care, drying, and correct anchoring, inflatable arches can last for many years. They are made from durable, UV-resistant materials suitable for repeated use at Australian outdoor events.
