Micro-DEP G (JMG) Series - Depth Style Vapor Phase Coalescing Elements

Features & Benefits

Ultra-fine depth style micro-fiberglass media for absolute 0.3 micron efficiency
Reverse flow (inside-to-outside) design for vapor phase coalescing applications
Engineered for removal of entrained low surface tension mists and aerosols
Graded density construction optimizes both coalescing efficiency and dirt holding
Varying fiber diameters create tortuous path for superior liquid capture
Robust construction maintains integrity under high differential pressure
Effective removal of water, oil vapor, and other liquid contaminants
Multiple configurations available with various gasket and end cap options
Tinned steel or stainless steel hardware for corrosion resistance
Designed for vertical coalescer vessels with inside-to-outside flow

When Absolute 0.3 Micron Efficiency is Critical

The Micro-DEP G Series is the trusted choice when your application demands absolute 0.3 micron coalescing efficiency in a depth-style element. The ultra-fine micro-fiberglass media captures the smallest aerosols and mists that can damage sensitive downstream equipment, contaminate products, or cause process upsets.

Depth Style vs. Pleated Coalescing

Micro-DEP G (Depth Style)

Graded density media creates multiple capture zones
Better performance with variable liquid loads
Handles sticky or viscous contaminants well
More forgiving in upset conditions
Ideal for glycol, amine, and lube oil mists
Inside-to-outside flow reduces re-entrainment

Pleated Coalescing (Micro-LOK G)

Higher surface area per element
Lower initial pressure drop
Longer service life in clean applications
Better for consistent, low liquid loads
Preferred when dirt loading is primary concern
More economical in stable conditions

Key Advantages

Absolute Efficiency

0.3 micron rated efficiency captures the finest aerosols that slip through standard coalescing elements.

Low Surface Tension Liquids

Excels at coalescing difficult low surface tension liquids like amines, glycol, and light hydrocarbons.

Depth Media Technology

Graded density fiberglass provides progressive filtration with superior liquid coalescence.

Reverse Flow Design

Inside-to-outside flow pattern reduces gas velocity at the outlet, minimizing liquid re-entrainment.

Common Applications

Compressor Discharge

Remove lube oil aerosols and moisture from compressor discharge gas streams.

Glycol Contactor Outlet

Capture glycol carryover from dehydration unit contactors to protect downstream equipment.

Amine Contactor Outlet

Remove amine mist from sweetening unit outlet gas to prevent contamination.

Vertical Coalescer Vessels

Second-stage coalescing in vertical separator vessels for final liquid polishing.

Instrument & Fuel Gas

Final polishing for instrument gas and fuel gas systems requiring ultra-clean output.

Molecular Sieve Protection

Remove liquid contaminants upstream of molecular sieve beds to preserve adsorption capacity.
