Strainers
Y-Type / Basket Type | DN15 - DN600
ZNX strainers remove rust, scale, welding residue and other pipeline debris from the flowing medium, protecting pumps, flow meters, heat exchangers, spray nozzles and downstream valves from damage and blockage. They are an essential part of every professional piping system.
Our range includes compact Y-type strainers for liquid, gas and steam lines, and basket strainers with large filtration capacity for high-flow applications. Screens are available in perforated stainless steel or woven mesh, with filtration grades from 0.5 mm to 8 mm. All models feature a drain plug or blow-off connection for quick in-line cleaning.
