Technology and Materials
Our bunkers are built for intensive commercial use thanks to their durable PVC construction, double-seam technology, and high-quality materials.
Each AIRBUNKER is made from 650gsm PVC fabric with welded seams, automatic valves, and reinforced attachment points. All shapes are field-tested and have countless hours of commercial use in paintball and laser tag arenas worldwide.
High-quality

650 g/m² density PVC durable fabric
Our bunkers are made of durable 650g/m² PVC fabric, so they can easily withstand the intense playing conditions of commercial use for a 10-year service life (12-month warranty).
Material specifications:
Thickness: 0.5–0.55 mm.
Density: 650 g/m².
Temperature range: −15 °C to +40 °C.
Water-resistant: suitable for outdoor use.
UV-resistant: protects against sunlight degradation.
Fuel- and oil-resistant: withstands contact with common substances.
Rot- and mildew-resistant: maintains properties over time.
This heavy duty PVC fabric is specifically engineered for rough gameplay conditions. The material won't rot and retains its properties within the specified temperature range.
Important note:
At ambient temperatures below +15 °C, the PVC fabric becomes less elastic. We don't recommend inflating, deflating, folding, or unfolding the bunkers below this temperature, as this may cause premature material damage.
Double seam technology
This technology strengthens joints against tearing, abrasion, and impact stress. The heat-welded seams are tested for intensive commercial use.
01
Heat-welded seams for maximum strength
02
Tested against repetitive paintball impacts
03
Resistant to tearing and abrasion
04
Suitable for intensive commercial use
Automatic spring-loaded valve
The Sport Classic valve consists of two main parts: the valve body and the cap. A rubber seal built into the cap protects it. This creates maximum tightness.
Valve features:
Automatic spring-loaded mechanism
Rubber sealing ring for tight closure
Valve protection with hook-and-loop fastener
Prevents valve contamination and damage
Can be fixed in the air supply and exhaust positions
The inflatable process is designed to ensure the valves remain sealed the bunker’s service life. Proper valve operation is critical to maintaining the desired inflation pressure.
Important note:
Please also ensure no heating devices, open flames, or pyrotechnics are used near the inflatable shelters.
Proper inflation guidelines
We recommend inflating the bunkers only until they are fully shaped — not until they are maximally tight. Once the bunker has taken its proper shape, check the surface with your hand.
Inflation guidelines:
01
Inflate until fully shaped, not maximally tight.
02
The surface should feel sturdy but not overly tight.
03
A light push with the palm should deflect the surface inward by approximately 12–20 cm.
04
The bunker needs to remain soft enough to absorb impact energy.
05
Prevents unwanted sharp ricochets or unnecessary stress on PVC.
Temperature considerations:
01
If temperature rises during the day or bunkers are exposed to direct sunlight, internal air pressure will increase.
02
Release some air by pressing the valve core until the pressure returns to normal.
03
When temperature drops, internal pressure decreases, so bunkers may need additional inflation.
Heavy-duty tie-down system
A tie-down rope secures the bunker to the surface. Elastic straps connect the bunker to ballast weights.
Features:
Heavy-duty tie-down rope
Elastic straps for ballast weights.
Secure anchoring system.
Prevents bunker movement during operation.
Maintenance and care instructions
When moving the bunkers around the field, do not drag them across the ground, as this can damage the PVC and significantly shorten their service life.
Cleaning instructions:
01
If a bunker becomes dirty during operation, clean it thoroughly before folding.
02
Dirt and sand left on the surface can abrade the PVC when folded
03
Use water and mild detergent such as soap or shampoo.
04
Avoid chemical reagents, solvents, and abrasive materials.
05
After cleaning, wipe with a dry cloth and allow to dry completely before storage.
Important warnings:
01
Avoid contact with solvents such as acetone, ethyl acetate, or paints based on these materials.
02
Do not use heating devices, open flames, or pyrotechnics near inflatable shelters.
03
Keep domestic animals away from the bunkers.
04
Do not drag bunkers across the ground.
Quality testing
We carefully consider every detail of the bunkers. Each batch undergoes rigorous quality testing before use.
Material Quality Check
Before use, each batch of PVC material is subjected to a number of rigorous tests for:
- Quality of adhesive bonding.
- Strength and elasticity.
- Compatibility with paintball paint.
- UV, water, fuel, and oil resistance.
- 02
Leak Test
Each batch of bunkers is inflated to full density and held under such conditions for 48 hours in storage.
48Hours - 03
High-Pressure Test
When inflated, an AIRBUNKER bunker can support a vehicle weighing more than 2000 kg.

Faq
What materials are AIRBUNKER bunkers made of?
All bunkers are made from heavy duty PVC fabric with a density of 650 g/m² and thickness of 0.5–0.55 mm. The material is UV, water, fuel and oil resistant, and retains properties between −15 °C to +40 °C.
What is double seam technology?
Double seam technology provides joint robustness against tearing, abrasion and impact stress. The seams are heat-welded and tested against paintball marker fire at point-blank range.
How does the inflatable manufacturing technology work?
The inflatable manufacturing technology includes material certification, precision cutting, heat-welded seam application and comprehensive quality testing. Each batch undergoes leak tests, high-pressure tests and impact resistance validation.
What is the inflatable process for setup?
The inflatable process includes proper inflation until fully shaped (not maximally tight), securing with tie-down ropes and elastic straps, and adjusting pressure for temperature changes. Surface should deflect 12–20 cm with light palm push.
How does PVC inflatable technology ensure durability?
The PVC inflatable technology uses 650 g/m² density fabric with UV, water, fuel and oil resistance. Proper inflation, maintenance and temperature management ensure the material performs as designed for over 10 years.
Can I order custom bunkers?
Yes. The custom inflatable manufacturing capability allows production of bunkers according to customer's design, including custom shapes, colors and logo application.
What temperature range is safe for bunkers?
PVC retains properties across the specified temperature range. Do not inflate, deflate, fold or unfold below +15 °C, as the material becomes less elastic and may suffer premature damage.
How do I clean the bunkers?
Use water and mild detergent such as soap or shampoo. Avoid solvents, acetone, ethyl acetate and abrasive materials. Dry completely before storage to prevent abrasion during folding.
What testing do bunkers undergo?
Each batch undergoes material quality checks, 48-hour leak tests, high-pressure tests (withstand 2000+ kg vehicle) and impact tests (paintball marker fired point-blank at seams).
How long do AIRBUNKER bunkers last?
Following proper operation conditions, inflatable pieces can serve more than 10 years. Service life depends on maintenance, storage, transport and adherence to inflation guidelines.
