Big Blue / Big Clear

Summary

Product identification

Big Blue/Big Clear Cartridge Housings are designed to meet larger capacity filtration needs, reducing the number of housings required for high-flow applications.

• Type: Cartridge Housings
• Sump Construction: Durable reinforced polypropylene (Big Blue), Lexan (Big Clear)
• Cap Material: Polypropylene
• Button Assembly: 300 Series Stainless Steel, EPDM, and Polypropylene
• O-ring: Buna-N
• Key Features:
  • Large capacity housing
  • Big Clear Filter Housings offer on-site examination of flow, performance, and cartridge life
  • 1.25” internal port for a greater volume of liquid to pass through the high-flow polypropylene cap
  • Accepts 4.5” diameter cartridges
  • Compatible with a broad range of chemicals

Applications

• Heavy sediment applications
• High-flow applications

Operating limits

• Max. Temperature: 100°F (37.8°C)
• Max. Pressure:
  • #10 Big Blue: 100 psi (6.9 bar)
  • #20 Big Blue: 90 psi (6.2 bar)
  • #10 Big Clear: 100 psi (6.9 bar)
  • #20 Big Clear: 90 psi (6.2 bar)

CAUTION: Protect against freezing to prevent cracking of the filter and water leakage.
