Unlike office or household extinguishers, motorsport systems are installed in vehicles exposed to extreme temperature changes, vibration and harsh environments — often stored in unheated garages or competing in freezing conditions.\u003c\/p\u003e\n\u003cp\u003eTo operate safely in low temperatures, AFFF extinguishers contain an anti-freeze agent. Over time, this can crystallise, potentially affecting system performance and reliability. This is why FIA and Motorsport UK regulations require servicing every two years.\u003c\/p\u003e\n\u003ch3\u003eMy extinguisher expiry says June. Does it expire at the beginning or end of the month?\u003c\/h3\u003e\n\u003cp\u003eYour extinguisher remains valid \u003cstrong\u003euntil the end of the stated month\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eWith Race Rally Supplies, your PD extinguisher is professionally serviced, compliant and ready for competition.\u003c\/p\u003e\n\u003ch3\u003eHow long will it take to service my extinguisher?\u003c\/h3\u003e\n\u003cp\u003eThis depends upon the time of year that we receive the cylinder but usually we can turn them around in 2-3 days. Delivery back to you is a 2-3 day service so please allow 7-10 days in total.\u003c\/p\u003e\n\u003ch3\u003eStainless steel is heavier than mild steel, so how are PD systems lighter?\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eIn many cases, PD systems can be \u003cstrong\u003eup to 4kg lighter\u003c\/strong\u003e than equivalent mild steel systems. Because of the strength of the stainless steel cylinder design, there is \u003cstrong\u003eno requirement for the heavy internal bladder\u003c\/strong\u003e commonly used in mild steel systems, helping reduce both weight and complexity.\u003c\/p\u003e\n\u003cp\u003eThis makes PD systems particularly attractive for motorsport applications where reducing vehicle weight is important.\u003c\/p\u003e\n\u003ch3\u003eWhy is PD extinguisher servicing cheaper than some other brands?\u003c\/h3\u003e\n\u003cp\u003eThere are a couple of reasons for this. The main factor is the \u003cstrong\u003estainless steel cylinder design\u003c\/strong\u003e, which removes the need for the internal bladder commonly found in mild steel cylinders.\u003c\/p\u003e\n\u003cp\u003eWithout the bladder, servicing requires \u003cstrong\u003efewer replacement materials and less labour time\u003c\/strong\u003e, helping reduce overall servicing costs while still maintaining FIA and Motorsport UK compliance.\u003c\/p\u003e\n\u003cp\u003eThe result is a professional, compliant servicing process that can often be completed at a lower cost than comparable systems.\u003c\/p\u003e","brand":"PD Extinguishers","offers":[{"title":"AFFF Handheld Service","offer_id":54576407347529,"sku":"PDAFHHS","price":29.99,"currency_code":"GBP","in_stock":true},{"title":"HAYLO Handheld Service","offer_id":54576407380297,"sku":"PDHHHS","price":29.99,"currency_code":"GBP","in_stock":true},{"title":"AFFF 4.25 Litre Mechanical Service","offer_id":54576383099209,"sku":"PDAFMSERV","price":45.99,"currency_code":"GBP","in_stock":true},{"title":"AFFF 4.25 Litre Electrical Service","offer_id":54576407413065,"sku":"PDAFESERV","price":45.99,"currency_code":"GBP","in_stock":true},{"title":"AFFF 4.25 Litre Electrical Service (for a discharged cylinder)","offer_id":54576447652169,"sku":null,"price":159.99,"currency_code":"GBP","in_stock":true},{"title":"HAYLO 4kg Service","offer_id":54576407445833,"sku":"PDH4KGS","price":54.99,"currency_code":"GBP","in_stock":true},{"title":"HAYLO 4 kg Service (for a discharged cylinder)","offer_id":54576447684937,"sku":null,"price":169.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/9463\/0729\/files\/pd-extinguisher-servicing-revalidationextinguishersrace-rally-suppliespdafhhs-1117080.png?v=1782665901","url":"https:\/\/rrs-store.co.uk\/products\/pd-extinguisher-servicing","provider":"Race Rally Supplies","version":"1.0","type":"link"}
