Description

Haskel Model 86921 Air-Driven Oxygen Gas Booster

Catalog literature: Gas Booster Catalog.pdf Acrobat DC

With a nominal pressure ratio of 25:1 (2nd stage ratio N/A), the Haskel model 86921 Oxygen gas booster is a Single-Acting, Single Stage design that utilizes air pressure to boost Oxygen gas pressures to a maximum of 4500 psi PSIG.

Features & Benefits:

  • Reliable, easy to maintain, compact and robust
  • No heat, flame or spark risk
  • Infinitely variable cycling speed and output
  • Pneumatic driven units to not require electrical connections
  • Easy to apply automatic controls
  • No limit or adverse affect to continuous stop/start applications
  • Seal systems designed for long working life
  • No air line lubricator required
  • Hydrocarbon free – separation between air and OXYGEN sections
  • Built-in cooling (most models)
  • Suitable for OXYGEN gas
  • Ability to stall at any predetermined pressure and hold the fixed pressure without consuming power or generating heat
