Haylo Combo 2 Kit 4Kg Mechanical Stainless Steel Fire Suppression System + 2.4L AFFF Hand Held Extinguisher

The Haylo 4Kg Mechanical Stainless Steel Fire Suppression System – Combination 2 is an FIA approved motorsport fire extinguisher system, supplied with a 2.4 litre AFFF hand-held fire extinguisher for additional fire protection.

Designed for race, rally and high-performance competition vehicles, this combination provides both an installed fire suppression system and a portable extinguisher, giving competitors comprehensive fire protection while meeting the requirements of modern motorsport.

The Haylo suppression system is FIA approved to EX.057.19, with a 16-year life cycle, while the supplied 2.4 litre hand-held extinguisher uses AFFF foam and has a 16-year life cycle.

Haylo 4Kg Mechanical Fire Suppression System

The Haylo 4Kg system uses a mechanical activation system and a stainless steel cylinder designed specifically for the demands of motorsport.

Mechanical System Features

• FIA Approved: EX.057.19
• 4kg suppression system
• Mechanical pull-cable activation
• Stainless steel cylinder construction
• Cylinder weight: 5.96 kg
• 16-year life cycle
• Designed for race, rally and circuit competition

The mechanical activation system provides a straightforward and proven method of triggering the fire suppression system, making it suitable for a wide range of competition vehicles.

2.4 Litre AFFF Hand Held Fire Extinguisher

The combination also includes a 2.4 litre AFFF hand-held fire extinguisher, providing a portable means of tackling a fire.

The extinguisher uses AFFF foam (Aqueous Film Forming Foam), making it suitable for a range of common vehicle fire risks.

Hand Held Extinguisher Features

• 2.4 litre capacity
• AFFF foam agent
• Hand-held design
• Motorsport UK compliant
• 16-year life cycle
• Suitable for competition vehicle use

The hand-held extinguisher provides an additional layer of protection alongside the installed Haylo suppression system.

Why Use a Combination System?

Having both an installed suppression system and a hand-held extinguisher provides competitors with two different methods of fire protection.

The Haylo 4Kg system is permanently installed within the vehicle and can be activated rapidly in the event of a fire.

The 2.4 litre AFFF extinguisher provides a portable option that can be used to tackle a fire directly where appropriate.

This makes the combination particularly useful for competition vehicles where additional fire protection is required.

Stainless steel is heavier than mild steel, so how are PD systems lighter?

This is a common question. While stainless steel is typically heavier than mild steel, the design and strength of PD stainless steel cylinders allow them to be manufactured more efficiently, reducing overall system weight.

In many cases, PD systems can be up to 4kg lighter than equivalent mild steel systems. Because of the strength of the stainless steel cylinder design, there is no requirement for the heavy internal bladder commonly used in mild steel systems, helping reduce both weight and complexity.

This makes PD systems particularly attractive for motorsport applications where reducing vehicle weight is important.

Why is PD extinguisher servicing cheaper than some other brands?

There are a couple of reasons for this. The main factor is the stainless steel cylinder design, which removes the need for the internal bladder commonly found in mild steel cylinders.

Without the bladder, servicing requires fewer replacement materials and less labour time, helping reduce overall servicing costs while still maintaining FIA and Motorsport UK compliance.

The result is a professional, compliant servicing process that can often be completed at a lower cost than comparable systems.

Can I buy spares for these systems?

Yes. We have a full range of spares HERE.

Do you have extra nozzles available?

 Yes we do, you can find a full range of nozzles HERE.

What is the advantage of the 16-year life cycle?

It reduces long-term replacement frequency and lowers overall cost of ownership.

Is it suitable for rally cars?

Yes. It is widely used in rally, race and track day vehicles.
