3/4" Standpipe Assy Cat 5 c/w 20 MDPE

Industrial and tamperproof Standpipe assembly with hose outlet, suitable for Fluid Category 5 applications. A break tank with Type AB air gap is mounted to the top of the Standpipe body, which provides the Fluid Category 5 backflow protection. The tank is filled via a compact float valve which prevents any overflow from the two screened weir slots. Water is supplied by gravity from the break tank to the hose outlet 1500 mm below, resulting in an outlet pressure of 0.15 bar. As the pressure is achieved using gravity rather than a booster pump, there is no power supply needed. The Standpipe has a hinged door adjacent to the outlet, which is where the operating valve is accessed. When not in use, the door should be locked using the key provided, to prevent misuse or tampering. Once the operating valve is shut, the water in the Standpipe’s internal pipework and tank is drained to prevent any “dead legs”. The permanent Standpipe features a flange at its base for bolting to a horizontal hard surface. The robust galvanised stainless steel housing provides a degree of frost protection.
Product Code: SPFC5x20
