High Capacity Coalescing Filters

385AHP-390AHPIntroducing Our Low Cost, High Efficiency, High Pressure, 100% Machined Aluminum Assembly

Protect sensitive equipment, dry seal compressors and high volume air & gas applications with our large coalescing filter assemblies. These filters, like their smaller counter parts utilize our microfiber elements to remove upwards of 99.99% of contaminates at 0.01 micron. The 385AHP/390AHP series of coalescing filters have increased liquid holding capacity and are available with optional high volume automatic float drains (with function above 12 psi), and differential pressure indicators which are sensitive in the 2 to 16 psi differential.

Features:

  • Rugged, 100% Machined Anodized Aluminum Construction
  • Remove 99.99% Of Oil, Water, & Solids From Compressed Air & Other Gases
  • Capture Dirt, Coalesce Liquids

Applications:

  • Mainline Compressed Air Filtration
  • CNG Filtration
  • Pre-Filter / Solid Removal In Gas Lines
  • Dry Seal Protection

At the heart of our filter products is the filter element. Choosing the correct element insures proper results for your specific application:

Disposable Microfiber Elements

Disposable Microfiber Elements are most commonly used since they offer exceptional filtration, high flows with minimal pressure drops, and excellent chemical compatibility. These are ideal for use in sample conditioning, instrumentation, CNG, and Emission/Environmental service.

  • For Coalescing (liquid removal) and particle collection use our grade “CS”. We recommend starting with the 70CS which is rated at 95% efficient at 0.01 micron which provides outstanding filtration, at high flow rates.

Vapor Adsorption Cartridges

Our vapor adsorption cartridges are packed with either carbon/charcoal for oil vapor adsorption (designated as CC-TP) or Silica Gel for water vapor adsorption (designated as SG-TP).

  • These units are only for adsorption of oil or water vapor and should be preceded by at least one coalescing filter assembly (70CS).
  • Fuel Gas Filter
  • Accepts Microfiber, Stainless Steel, Vapor Adsorption, & Pleated Elements
  • Comes Standard With 70CS For Heavy Coalescing
