It runs on the 5\/16″ flexible dryer duct cable, not the 3\/8″ cable used for air duct work.\u003c\/p\u003e\n\u003cp\u003eBristles are a consumable. A worn brush still turns and still sounds like it is working, but it stops lifting compacted lint off the duct wall, so most operators carry a spare.\u003c\/p\u003e\n\u003ch2\u003eWhat it is for\u003c\/h2\u003e\n\u003cp\u003eClothes dryer exhaust ducts, commonly 100 mm in Australian domestic installations. The brush is driven through the duct on the dryer cable while vacuum is applied at one end, agitating packed lint so it is drawn out rather than pushed further along the run.\u003c\/p\u003e\n\u003cp\u003eThis is a fire risk task. Air-Care are explicit that cleaning the duct alone is not enough — lint inside the dryer's fan and heating area has to be removed as well.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003eAir-Care specify FG0072 for the Cobra IV and for dryer duct cleaning generally. It appears in the Cobra-5 parts list as a 4″ dryer duct brush with Lint Buster Ball, and is the brush supplied with both Air-Care dryer duct cables — FG0058 (5\/16″ core x 20 ft) and FG0060 (5\/16″ core x 35 ft).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis brush mounts to the 5\/16″ dryer cable, not the 3\/8″ standard cable.\u003c\/strong\u003e The two cores are different diameters and are not interchangeable. If you are running the standard air duct cable, the brush you want is the 18″ Flex-E-Bristle (SACOB0011).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCobra-7 compatibility is not confirmed.\u003c\/strong\u003e The Cobra-7 ships with the 3\/8″ cable and Air-Care do not list FG0072 in the published Cobra VII parts schedule. We have asked Air-Care to confirm whether the dryer cable and this brush are offered for that machine. Until they answer, do not assume it fits — contact us first if the Cobra-7 is what you intend to run it on.\u003c\/p\u003e\n\u003cp\u003eWe do not currently stock the 5\/16″ dryer cable itself — this brush is a replacement for operators who already have one.

Airflow is the honest measure. Air-Care's guidance is that over 1000 fpm at the exhaust is a good result and under 1000 fpm is not; if post-clean readings drift down across several jobs and nothing else has changed, look at the brush.\u003c\/p\u003e\n\u003ch2\u003eWarranty\u003c\/h2\u003e\n\u003cp\u003eAir-Care classify the brush assembly as a consumable and provide no manufacturer warranty period on it, as stated in the Cobra equipment manuals.\u003c\/p\u003e\n\u003ch3\u003eYour rights under Australian law\u003c\/h3\u003e\n\u003cp\u003eOur goods come with guarantees that cannot be excluded under the Australian Consumer Law.

The Cobra-7 runs a 3\/8″ cable and Air-Care do not list this brush in the Cobra VII parts schedule. We have asked them and will update this page when they answer.\u003c\/p\u003e\n\u003ch3\u003eWhat size duct does it suit?\u003c\/h3\u003e\n\u003cp\u003eClothes dryer exhaust ducts at 100 mm. For air conditioning ductwork from 100 mm to 457 mm, you want the 18″ Flex-E-Bristle brush on the standard cable instead.\u003c\/p\u003e\n\u003ch3\u003eWhat is the Lint Buster Ball?\u003c\/h3\u003e\n\u003cp\u003eA ball fitted at the tip ahead of the bristles. It leads the brush through bends and helps break up packed lint at the head of the run rather than compacting it further.\u003c\/p\u003e\n\u003ch3\u003eCan I run it on the standard 3\/8″ cable?\u003c\/h3\u003e\n\u003cp\u003eNo. It is made for the 5\/16″ dryer cable, and the cores are different sizes.\u003c\/p\u003e\n\u003ch3\u003eHow long does a brush last?\u003c\/h3\u003e\n\u003cp\u003eIt depends on how many runs it does and how abrasive the ducting is, so we will not quote a figure we cannot stand behind.

The trick is keeping the brush moving through bends while breaking lint away rather than forcing the cable when it meets resistance — that's when technicians start damaging ducting or their equipment. We also remind customers to check which Cobra cable they're using before ordering, because the dryer-duct setup is its own system and a brush that looks right isn't necessarily the right connection.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eNot sure which brush suits your machine?
