PBH Series

Summary

Product identification

The PBH Series Bag Housings are designed to keep systems on stream longer by reducing bag filter change time. These lightweight, corrosion-resistant polypropylene assemblies offer strength without excessive weight.

Features and benefits:

• Lightweight corrosion-resistant polypropylene construction.
• Single large ACME thread closure ensures quick opening and positive sealing.
• Outstanding chemical compatibility, making housings ideal for a variety of low-flow applications.
• Equipped with a black, reinforced polypropylene cap.
• Includes gauge, wrench, and 0.375” drain valve.
• Portable.
• Economically priced.
• Provides uninterrupted flow rates when installed as a duplex system.

Applications

• Commercial Water
• Food Service
• Industrial Chemical
• Industrial Water
• Residential Pre-filtration

Options

• Choice of 10” or 20” housings.
• Available in 1” and 1.5” NPT sizes.
• Bag vessel stand sold separately.
• Filter bags are available in polypropylene felt, absolute-rated high-efficiency polypropylene, and nylon monofilament mesh—ideal for filtering and straining applications from 1-800 microns.

Pressure Drop vs. Flow Rate

The datasheet provides approximate net pressure drop values for different flow rates for 1" and 1.5" NPT connections. See the official PDF for exact tabulated values and graphical representations.

Approximate Net Pressure Drop – psi (Bar) at various Flow Rate – gpm (Lpm):

• 1 (0.07) PSI @ 10 (37.8) GPM
• 2 (0.14) PSI @ 15 (56.8) GPM
• 3 (0.21) PSI @ 20 (75.7) GPM
• 4 (0.28) PSI @ 25 (94.6) GPM
• 5 (0.34) PSI @ 30 (113.6) GPM
• 6 (0.41) PSI @ 35 (132.5) GPM
• 7 (0.48) PSI @ 40 (151.4) GPM
• 8 (0.55) PSI @ 50 (189.3) GPM
