The NAFFCO Pre-piped Horizontal / Vertical Bladder tanks are an integral component of balanced pressure proportioning system. Its operation requires no external power other than a pressurized water system. NAFFCO bladder tank, with an appropriate proportioner, injects foam concentrate into the water supply of a fire protection system and automatically proportions at wide range of flows and pressures. NAFFCO Pre-piped Foam Horizontal / Vertical bladder tank is a steel pressure vessel fitted with an Internal Elastomeric bladder that stores foam concentrate. During operation, the concentrate is discharged by incoming water pressure to the bladder tank until the concentrate is depleted. The bladder tank discharges foam concentrate at approximately the same pressure as the water supplied at the water inlet connection to the tank. • UL LISTED/FM APPROVED/ASME 'U' STAMP/NBBI 'R' STAMP • Bladder material Vinyl Based Polymer or Buna-N or Neoprene. • Designed for Maximum agent discharge. • Pre-fabricated foam bladder proportioning system eliminates loose components and simplifies the installation. • Tanks are oversized to allow thermal expansion of foam concentrate if any.
