brass construction: Crafted from quality brass that resists oxidation, this water pressure reducer delivers durability and longlasting performance in challenging plumbing environments. The robust design provides stable pressure regulation for the entire system. Builtin filtration system: Features an integrated filter that captures scale, dirt, and sediment from the water supply, helping protect appliances and plumbing fixtures. This dualfunction design eliminates the need for a separate filtration component, saving installation time and space. Precise pressure monitoring: Clear, easytoread pressure gauge displays realtime readings within the 0.17.5 MPa range. The capacity inlet accepts up to 16 bar incoming pressure, enabling accurate adjustment and maintenance of water pressure throughout the property. Versatile compatibility: Standard 1/2' (DN15) and 3/4' (DN20) connections are compatible with most residential and commercial plumbing systems. Simple installation requires minimal tools, suitable for both professional plumbers and DIY enthusiasts. Use scenario: In a singlefamily home with fluctuating municipal pressure and hard water, the unit maintains stable household pressure while filtering out scale and sediment to protect appliances. Use scenario: In multiunit buildings, it helps protect fixtures and appliances across apartments by regulating pressure and filtering contaminants. Use scenario: In small commercial settings such as cafes or offices, it ensures consistent water pressure for equipment like espresso machines and fixtures, reducing the risk of damage and downtime.
