In the past, designing a pump proportioning system to protect a hazard with multiple zones has required numerous in-line balanced pressure proportioners (IBP) of various sizes. ANSUL FLOWMAX PPW Variable Range Proportioners represent a revolution in foam system design by eliminating the need for multiple IBPs.

A single FLOWMAX PPW:

• Eliminates the need for multiple IBPs of different sizes to accommodate a wide range of flows
• Requires only one proportioner in the header versus one per riser, reducing hardware cost and installation time
• Requires only one concentrate line, making for clean and cost effective installations
• Significantly reduces the equipment costs when replacing three or more IBPs
• Greatly reduces materials, maintenance and installation costs

PPW at a glance:

• UL Listed and FM Approved with ANSULITE 3% AFFF and ANSULITE 3x3 LV
• Similar in operation to the FLOWMAX CL proportioner
• Integral pressure balancing valve allows use with pump systems
• Available in 6 in. and 8 in. sizes
• Four models with various flow ranges from 55 to 4,875 gpm (208 to 18,453 Lpm)
• Compact, corrosion-resistant design
• Maintenance-free construction
• 2 in. raised face 150 lb ANSI flange foam inlet for all models
