BC4-3 Band Clamp Filter Housing
The Harmsco BC4-3 is a stainless steel band clamp filter housing holding 4 standard-diameter cartridges in one compact vessel. Its band-clamp closure opens without tools, so cartridge changes take minutes — a practical workhorse for commercial and light-industrial filtration. Like the rest of the BC line, housing and cartridges are BABA compliant (Build America, Buy America) for federally funded work, and a fusion-bonded epoxy coated version is available.
The BC4-3 handles flows up to 75 GPM at 150 PSI through 2″ FNPT connections, holding 4 cartridges of 29-1/4″ or 30″ length in a 1.2 Sq. Ft footprint at 67″ service height. It is built from 304 or 316 stainless steel with an electro-polished finish.
The BC4-3 band clamp filter housing uses standard 2-1/2″ and 2-3/4″ diameter cartridges — the most widely available format in the industry — so you can match micron rating and media from Harmsco’s NSF-certified range without proprietary lock-in.
BC housings serve commercial drinking water, food and beverage, reverse osmosis pre-filtration, cooling water, and light industrial process duties where fast, tool-free service keeps downtime short. Because four and six-round models share the same closure and cartridge format, plants can scale flow by adding vessels without changing spare-parts inventory or service procedures. Harmsco has manufactured filtration products in the USA, in Riviera Beach, Florida, since 1958.
