The A-Class Ultra Pro 3500 is an outdoor membrane whole-house water filter with a SUS304 stainless housing and double backwash. It fits on the incoming supply and treats water to the whole house rather than a single tap — the specification for sediment, discolouration and rust carried in the mains supply. Full technical specifications are in the datasheet linked from the product above.
An outdoor whole-house unit treats every outlet: showers, washing machine, kitchen and bathroom taps. A point-of-use filter treats one tap. Where the customer's complaint is discoloured or rusty water staining laundry and sanitaryware, the problem is the incoming supply and the whole-house unit is the correct answer. Where the complaint is drinking-water taste, a point-of-use unit is the cheaper fix.
The double backwash function flushes trapped sediment out of the media rather than requiring the housing to be opened. Customers should be told at the point of sale that periodic backwashing is normal operation, and roughly how often for their water condition — it prevents a support call that sounds like a product failure but is a maintenance step never explained.
Buying the Ultra Pro 3500 filter by the carton. A-Class supplies the trade only — hardware shops, plumbing merchants, contractors and project buyers. Minimum is one carton per item, and carton quantities are printed against every code above (unit quantities on request). Prices are not published: wholesale pricing depends on quantity and trade account, so it is quoted per enquiry.
