Description
Aska’s latest innovation in the SAFER® series introduces an advanced composite cylinder designed with cutting-edge Graphene Nano Tube technology. Graphene, a single layer of carbon atoms, is the thinnest material known and offers an exceptional surface area-to-volume ratio. This unique property makes the cylinder extremely lightweight while maintaining superior strength — up to ten times stronger than steel — ensuring maximum safety and durability in high-pressure environments.
These composite cylinders are ideal for rescue operations, breathing apparatuses, and other critical applications where reliability and performance are essential. With a focus on innovation and quality, Aska delivers cylinders that combine strength, longevity, and ease of handling, setting new standards in modern safety equipment.

What exactly are “Type-4 Carbon Composite Cylinders with Graphene Nano Tubes & PET Liner”?
They’re advanced breathing/air cylinders made with high-strength, lightweight carbon composite material, enhanced with graphene nanotubes and a PET liner. They are built to be lighter but highly durable, for rescue / high-pressure use. (Aska Equipments Private Limited)
How much pressure can these cylinders handle?
These cylinders are designed to work safely at 300 Bar (about 4350 psi). During testing, they are pressure-tested up to 450 Bar (about 6525 psi) to ensure durability and safety.
What is the service life of these cylinders?
They have a service life of 20 years.
Are they certified and what standards do they meet?
Yes — they are approved by PESO. They also comply with relevant EN standards.
What sizes are available (in litres)?
They are made in several variants: 4.7 L, 6 L, 6.8 L, 8 L, 9 L and 10 L.
How much lighter are they compared to older or metal cylinders?
For example, a 6.8 L variant of this type weighs about 3.3 kg (without valve), versus ~4.1 kg for a similar older carbon/aramid version — so you save ~800 grams.
Is the cylinder safe against damage, and what makes the graphene nanotubes helpful?
The graphene nanotubes and PET liner help increase strength, reduce weight, improve resilience. This makes the cylinder more robust in harsh conditions, with better performance vs standard steel or older composite bodies.
Can these cylinders be used for rescue, firefighting or industrial breathing systems?
Yes—they are designed for rescue use (breathing air, rescue operations) where weight, pressure capacity and reliability matter. They suit professional / industrial applications.
What happens after 20 years — can they still be used?
The service life is stated as 20 years. After that, the safe use would depend on condition, inspections, replacement rules, standards. It’s best to check with qualified service engineers.
