Entirely made of anodised aluminium alloy, the finishing touches of this diffuser are of very high quality. The stream patterns are adjustable in 3 or 5 positions. As of now this model exists with spinning teeth or cut teeth. PROSTOIA - without head sheath The cut-tooth versions of the PROSTOIA diffusers are an exclusive POK design. These teeth are shaped to better break up the water inside the cone. Thus, the diffused spray position has a 110° angle with a cone containing fine water droplets for better thermal protection. TECHNICAL CHARACTERISTICS. • Adjustable flow rate and purge by turning the selection ring. The available flow rates are engraved, you just have to rotate the head ring to the desired flow rate value. The manoeuver is facilitated thanks to the presence of capstan for a better grip of the selection ring and lock of the chosen position. • Adjustable spray thanks to the head ring also provided with engraved markings allowing to pass gradually from a full spray to the 30° attack spray position, called " flash over ", to a 110° cone-shaped diffusion in order to form a water screen. The flow rate is adjustable by simply turning the engraved notched ring. Switching from a spray pattern to another is as simple as turning the head ring. Straight spray, flash over (30°), wide angle spray (110°). 3 s t r e a m p a t t e r n s 3 s t r e a m p a t t e r n s 30° 110° F o r e l e c t r i c a l f i r e A d j u s t a b l e f l o w r a t e Inlet Flow rate (lpm) Working pressure (bar) Dimensions (mm) Weight (kg) Reference BSP Reference NST-NH Female 2.5'' 750 - 1000 - 1500 6 250 x 225 x 120 3.2 40790 41740 Female 2.5'' 800 - 1050 - 1300 - 1600 6 179 x 175 x 120 2.7 47148 47117 Female 2.5'' 750 - 1000 - 1500 - 2000 6 178 x 175 x 120 2.7 47120 Female 2.5'' 500 - 1000 - 1500 - 2000 - 2500 - 3000 6 246 x 225 x 120 32 40530 41637 Compatible with foam head ref. 42692 More information on diffuser teeth page 507 Inlet Flow rate (lpm) Working pressure (bar) Dimensions (mm) Weight (kg) Reference BSP Reference NST-NH Female 2.5'' 750 - 1000 - 1500 6 250 x 225 x 120 3.2 48219 48225 Female 2.5'' 500 - 1000 - 1500 - 2000 6 250 x 225 x 120 3.2 48221 48227 Female 2.5'' 500 - 1000 - 1500 - 2000 - 2500 - 3000 6 250 x 225 x 120 3.2 48223 48229 Female 3.5'' 2000 - 3000 - 4000 - 5000 7 250 x 225 x 120 3.2 Compatible with foam head ref. 42962 (réf. 20295 for 7 bar diffuser) More information on diffuser teeth page 507 Inlet Flow rate (lpm) Working pressure (bar) Dimensions (mm) Weight (kg) Reference BSP Reference NST-NH Female 2.5'' 750 - 1000 - 1500 6 250 x 225 x 120 3.2 48201 48207 Female 2.5'' 500 - 1000 - 1500 - 2000 6 250 x 225 x 120 3.2 48203 48209 Female 2.5'' 500 - 1000 - 1500 2000 - 2500 - 3000 6 250 x 225 x 120 3.2 48205 48211 Female 2.5'' 2000 - 3000 - 4000 - 5000 7 250 x 225 x 120 3.2 48213 Female 3.5'' 2000 - 3000 - 4000 - 5000 7 250 x 225 x 120 3.2 Compatible with foam head ref. 42962 (réf. 20295 for 7 bar diffuser) More information on diffuser teeth page 507 N e w p r o d u c t N e w p r o d u c t N e w p r o d u c t C o n f o r m t o n o r m Type 3 EN 15767-2 Adjustable flow rate and spray pattern diffusers
