Overview
Engine air cleaner element for the Sapphire 570. Sapphire part number 36-438, listed in the parts schedule as Element, Air Cleaner (570). Sapphire also identify it as Engine Air 2S-E1.
Fit the pre-cleaner as well
Sapphire list a companion part immediately after this one: 36-439, Precleaner, Air Filter. It is not currently a stocked CCW line — ask us.
The pre-cleaner is a foam wrap that catches the coarse material before it reaches the paper element. On a truckmount working in the dust that carpet cleaning and restoration generate, that is the difference between changing an element on schedule and changing it early every time.
An engine running without its pre-cleaner will go through paper elements. If you are buying elements more often than the hours justify, check whether the pre-cleaner is there.
Why air filtration matters more on a truckmount
A truckmount engine runs in an enclosed van, often on a site that is generating exactly the fine particulate an engine does not want — carpet fibre, gyprock dust, soot, and whatever demolition is happening nearby.
A restricted air filter costs power and fuel before it costs anything else, and the operator rarely notices because the loss is gradual. What they do notice, eventually, is a machine that will not make temperature or hold pressure under load — and by then the diagnosis usually starts somewhere expensive.
Check the air filter first. It is the cheapest thing in the chain.
Service advice
Do not wash a paper element. Washing damages the media and it will not recover. The pre-cleaner is the washable part.
Do not blow a paper element out with a compressed air line from the dirty side either — you drive the debris into the media and can blow holes straight through it. If you must clean one, low pressure from the clean side only, and inspect it against the light afterwards.
Check the sealing face and the housing every time. A perfect element in a housing that does not seal is doing nothing, and a filter housing that has been over-tightened or knocked out of shape is a common finding on machines that have been in and out of vans for years.
Replace on the engine manufacturer's schedule, and sooner on dusty work.
Frequently asked questions
Which machine is it for?
The Sapphire 570, per Sapphire's parts schedule.
Can I wash it?
No. It is a paper element.
Do I need the pre-cleaner too?
Yes, if your machine is specified with one. It is Sapphire 36-439 — ask us.
Will it fit a 370 or an 870?
Sapphire list this element against the 570. Tell us your machine and serial number and we will check the correct element rather than have you fit one that nearly fits.
Send us your machine model and serial number and we will confirm the element, the pre-cleaner and the service interval.
