Application nData Sheet

4 20ma basics
4-20mA Basics
  • Can be run long distances with minimal loss ~1,000 ft+
  • Varying impedance or supply voltage will not affect the signal.
  • Low electromagnetic susceptibility
  • Only requires 2 wires to operate
king filters
KING Filters
  • Single stage or dual stage
  • Main Line or Point of use
  • Polisher Selection
  • Scrubber Selection
coalescing filtration
Coalescing Filtration
  • Compressed air enters
  • Travels through filter media
  • Oil and water attach to fibers
  • Grow into droplets and fall off into bowl
  • Replace elements yearly or as needed

King’s Outside to Inside Flow
  • More surface area for particulate
  • Nozzle shaped outlet for better discharge
removing oil water vapor
Removing Oil/Water Vapor
  • Using desiccants to remove vapor through adsorption
desiccant dryers
Desiccant Dryers
  • Compressed air passes through an adsorbent media (desiccant) such as activated charcoal, silica gel, or molecular sieve.
