The nozzle can be continuously adjusted between a jet stream and a fine mist spray, with an average stroke of 1.2 ml per spray. This makes it the standard attachment for 1,000 ml HDPE cylindrical bottles, which detailing professionals use to fill their own cleaners, quick detailers, and sealants.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_hero.jpg?v=1776204868\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon on workbench at porsche gt3 rs loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContinuously adjustable nozzle from jet stream to mist.\u003c\/strong\u003e A twist of the head switches between a targeted stream for rims and insect residue and a fine aerosol for finish sprays or plastic care.

Cheap discount spray heads lose spring tension after two to three weeks with aggressive cleaners — the CHS-3AN is not designed for that.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e The most common confusion concerns the thread. 28\/400 and 28\/410 look identical but only seal properly on the correct bottles. The Canyon CHS-3AN spray head belongs on our 1,000 ml HDPE cylindrical bottle and on any third-party bottle with a 28\/400 neck size. For the original 500 and 750 ml Koch-Chemie bottles, you need the \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-opus-28-410\"\u003eOpus spray head\u003c\/a\u003e with a 28\/410 thread. The wrong thread means: it sits crooked, doesn't seal, draws air, and sprays unevenly.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eContinuously turn. Holding tab for continuous operation.\u003c\/h3\u003e\n\u003cp\u003eThe Canyon CHS-3AN spray head works with a rotating head that has four main positions: OFF (closed), Stream (jet stream), Spray (mist), and the continuous intermediate stages. The \"Stream\" setting delivers a concentrated jet with a range of up to approx. 40 cm — ideal for wheel arch gaps or targeted insect pre-treatment on the hood. In \"Spray\" mode, the nozzle atomizes into a fine aerosol, which is evenly distributed over approx. 25–30 cm.\u003c\/p\u003e\n\n\u003cp\u003eFor continuous operation during foam washing or extensive quick detailer application, the CHS-3AN has a holding tab on the trigger. You push the trigger all the way through and slide the small plastic tab forward — the spray head then remains open without you having to hold it. This saves your wrist when working on larger vehicles and makes extensive application on station wagon roofs or SUV side panels much more relaxed.\u003c\/p\u003e\n\n\u003cp\u003eThe piston mechanism is designed as a \"Ring-Lip-Piston\" — this is Canyon terminology for a sealing lip that yields under pressure and seals cleanly on the return stroke. In practice, this means that even after 2,000 to 3,000 spray intervals, the stroke remains constant at 1.2 ml, provided you have not blocked the head with drying chemicals.\u003c\/p\u003e\n\n\u003cp\u003eClean working means setting the nozzle to OFF after each application and briefly flushing clear water through with aggressive cleaners. Otherwise, surfactants and waxes will dry in the internal channel and block the valve after a few days. Those who ignore this will replace a 4-euro spray head every three months instead of every two years — this is by far the most common reason why spray heads fail prematurely.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_anwendung.jpg?v=1776204868\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon being used on vehicle loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\n\u003ch3\u003eFits 28\/400. Not 28\/410.\u003c\/h3\u003e\n\u003cp\u003eThe CHS-3AN fits any bottle with a 28\/400 thread — this is the European standard for 1,000 ml HDPE cylindrical bottles in the detailing segment. These bottles include our \u003ca href=\"\/en\/products\/koch-chemie-hdpe-zylinderflasche-28-400-spruehflasche-1000ml\"\u003eHDPE cylindrical bottle 28\/400\u003c\/a\u003e, the CarPro Dilute bottles, and most neutral empty bottles from detailing wholesalers.\u003c\/p\u003e\n\n\u003cp\u003eThe number \"28\/400\" refers to two things: the neck outer diameter (28 mm) and the thread type according to the SPI standard (400 = flat thread with 6.3 turns per inch). The 28\/410 thread is almost identical in diameter but has a different flank geometry. The difference is hardly visible — but measurable: a 28\/410 spray head on a 28\/400 bottle sits crooked and only seals on one side.\u003c\/p\u003e\n\n\u003cp\u003eThe spray head is not suitable for the original 500 ml and 750 ml bottles from Koch-Chemie — these have a 28\/410 thread and come with their spray head supplied ex works. For 28\/400 bottles, the Canyon CHS-3AN spray head is the suitable component, but not a replacement for high-pressure pump sprayers like an iK Multi 3 or iK Foam Pro 2. The delivery rate is sufficient for manual detailing, not for active pressure build-up or foam generation.\u003c\/p\u003e\n\n\u003cp\u003eIf you often switch between spraying overhead and normal spray direction, it's worth taking a look at the \u003ca href=\"\/en\/products\/ik-sprayers-spruehkopf-ik-trigger-multi-tr-1-360-canyon-chs3an\"\u003eiK Trigger 360°\u003c\/a\u003e from the same Canyon family. This also sprays overhead — relevant for wheel arch cleaning or in tight engine compartments — has the same 28\/400 connection, but costs one euro more per piece and about five euros more in a five-pack.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_detail.jpg?v=1776204868\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon in hand workshop loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\n\u003ch3\u003eYour workhorse for self-filling cleaners\u003c\/h3\u003e\n\u003cp\u003eThe Canyon CHS-3AN spray head is the right choice if you dilute concentrates like Green Star, Pol Star, or Finish Spray Exterior yourself and work with 1,000 ml spray bottles. For workshops and detailers who use several bottles in parallel, it's worth buying as a spare part — a second spray head costs less than a new bottle plus head.\u003c\/p\u003e\n\n\u003cp\u003eIt is less suitable if you only buy pre-packaged spray products from Koch-Chemie, as these come with the Opus spray head already assembled. It also has no place in 5-liter canister operations — there, a pump sprayer or pressure sprayer does the work. Also not an area of application: highly acidic wheel cleaners like Koch-Chemie Rim Cleaner Acid (Rrp). The acid resistance of the CHS-3AN ends at pH values around 2.5 — anything below that attacks the seals in a few weeks.\u003c\/p\u003e\n\n\u003cp\u003eIf you're starting from scratch, go straight for the \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-spruehflasche-set\"\u003eSpray Head + 1,000 ml HDPE Bottle Set\u003c\/a\u003e. The set costs 7.49 euros compared to 7.98 euros for the individual parts — two fewer items in the shopping cart and a bottle that fits perfectly sealed ex works. For labeling your self-filled bottles, a waterproof industrial marker or a pre-printed label is essential: contents, dilution, filling date. An unlabeled spray bottle with diluted APC next to one with diluted glass cleaner is a classic detailer's mix-up — and exactly why professionals label every bottle.\u003c\/p\u003e\n\n\u003cp\u003eThe Detailing1-Insight to conclude: If you're honest, you don't replace the Canyon CHS-3AN spray head because of a defect, but because of contamination. A spray head that has been used for APC for years can never be fully converted to glass cleaner — microscopic surfactant residues in the internal channel will foam up the glass cleaner and leave streaks. The solution is a fixed assignment: one spray head per product type.\u003c\/p\u003e\n\n\u003cp\u003eIn the workshop, you label the trigger directly with a dot from a paint marker. Green for glass cleaner, Red for APC, Blue for quick detailer, Yellow for IPA wipes. Four heads, four bottles, no confusion — and each head will then last its two to three years because it runs with consistent chemistry and doesn't see different surfactants every week.\u003c\/p\u003e\n\n\u003cp\u003eRegarding durability in numbers: With daily professional use and correct care (flushing with water after use, OFF position for storage), the Canyon CHS-3AN spray head achieves an average of 18,000 to 25,000 spray intervals. With a stroke of 1.2 ml, this corresponds to approximately 25 to 30 completely emptied 1,000 ml bottles before valve tension or the sealing lip noticeably degrades. Hobby detailers practically never replace the head due to wear, but only due to contamination or a misplaced bottle.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_closeup.jpg?v=1776204869\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon in hand workshop loading=\"lazy\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"Default Title","offer_id":48488820212047,"sku":"D1-KCX-CHS3AN","price":4.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-spruehkopf-star-chs-3an-canyon.png?v=1722941263","url":"https:\/\/detailing1.nl\/en\/products\/koch-chemie-spruehkopf-star-canyon-chs-3an","provider":"Detailing1","version":"1.0","type":"link"}
