ATTACK 500 PRO Selectable Gallonage Nozzle

The Attack 500 Pro Series Fire Nozzle is designed for use with low pressure mainline hoses providing exceptional performance and long-term value for money. Manufactured in the UK to exacting standards under an ISO9001 Quality Management System the Attack 500 Pro represents the very best in front-line professional firefighting nozzles. Subtle design enhancements and computer-aided flow engineering combined with high quality, corrosion resistant materials ensure a long service life with minimal maintenance.
Stainless steel spinning turbine teeth produce a dense, wide angle fog pattern with small diameter water droplets enhancing firefighting capabilities and significantly improving firefighter safety. A specially profiled stainless steel ball valve reduces jet reaction when using ‘pulsing’ techniques and enhanced hydraulic efficiencies produce a powerful, penetrating, long-range jet.

We believe this to be a ‘Best in Class’ nozzle, a view endorsed by the increasing number of devotees across leading Municipal and Industrial Fire Services around the globe including one of the world’s largest Fire Authorities, London Fire Brigade. With a range of flow options and colour ways the Attack 500 Pro is suited for use with all International inlet fittings to ensure compatibility with existing equipment. 

The Delta Attack 500 Pro nozzles boast a host of special features designed to maximise performance and ensure the highest possible level of safety for the operator. More than 25 years of ongoing research and development has culminated in a state-of-the-art nozzle highly regarded by industry professionals globally.

Spinning Teeth
Computer designed stainless steel spinning turbine teeth chop the water up into finely
divided, small diameter water droplets producing extremely dense fog patterns
enhancing firefighting capabilities and significantly improving firefighter safety.
Impervious to damage, even when dropped onto a hard surface, the stainless steel teeth
provide considerable advantages over the more commonly used plastic teeth.

Profiled Ball Valve
Using a specially profiled stainless steel ball valve deigned to minimise ‘jet-reaction’, the
Attack 500 Pro is ideal for ‘pulsing’ techniques when combatting flash-over risks in
compartment fire scenarios. Unlike plastic ball valves as used by most manufacturers the
stainless steel Delta valve ensures long-term durability and enhanced performance.

Raised Indicators
The Attack 500 Pro incorporates a tactile raised indicator on both the front bumper and
dial collar to assist firefighters in selecting spray patterns and flow settings in low light
levels where visibility is impaired by smoke. The indicators are easy to locate in a gloved
hand and ensure the operative is fully in control at all times.

On-Off Control Handle
The Pro-Series range incorporates an ergonomically designed flow control handle that is
designed to allow enhanced clearance between the nozzle body handle in any operating
position when using a gloved hand. Manufactured from high-impact materials the
control handle will absorb impact when dropped or dragged and allows for smooth flow
control in all operational situations.

PTFE Top Hat
The Attack 500 Pro incorporates friction-resistant PTFE bearings on the control handle
spindles to ensure wear is minimised during use. Test results on a repetitive action
simulation unit carried out to replicate many thousands of operations of the control
handle show that this innovative addition contributes to a significant reduction in wear,
extending the service life of the nozzle and minimizing the need for maintenance.

Flow Engineering
The Pro-Series incorporate the very latest in computer-aided flow engineering with
enhanced design concepts that stabilise flow and performance where water pressures
are low to maximise operational capability. High quality UK manufactured componentry
precision made to rigorously controlled tolerances guarantee powerful jet function and
coherent spray patterns.

Permanent Markings
All markings on the Attack Pro-Series are laser etched providing a permanent reference
to flow settings, spray patterns and on/off control settings.
