Description

Part No: E31175XA

Core Technical Specifications

Mandatory inlet pre-treatment: Liquid oil residual ≤0.01 ppm

Adsorption Media: Food-grade high-specific-surface-area granular coconut shell activated carbon, acid-resistant, anti-hydrolysis, ultra-low carbon dust shedding

Max allowable inlet relative humidity: ≤60% RH; dry inlet air extends adsorption service life significantly

Clean, low-humidity general workshop: 4,000 working hours / 12 months

Paint shop, high humidity, heavy oil load, 24/7 continuous production: Shorten to 1,800–2,800 hours

Mandatory replacement trigger: Obvious oily odor at air outlet or differential pressure ΔP ≥ 0.07 MPa

Differential Pressure Thresholds

Initial pressure drop of brand-new element: ≤0.015 MPa

Alarm replacement differential pressure: ΔP ≥ 0.07 MPa

Stainless steel perforated support cages: Anti-rust, anti-corrosion, prevents carbon core deformation under large airflow surges

Dual microfiber barrier layers: Fully wrap carbon granules to block fine carbon dust entering downstream pipelines

Static conductive composite framework eliminates static accumulation fire risk in oil-air mixed working environments

Key Product Advantages

High-capacity coconut shell activated carbon with long adsorption service life

Ultra-high specific surface area carbon granules provide massive oil vapor adsorption capacity, slowing saturation throughout full service cycle. Double-layer microfiber barriers lock fine carbon dust inside the cartridge to avoid pipeline contamination.

Humidity-resistant media structure to prevent premature carbon failure

Specially engineered anti-hydrolysis carbon formulation tolerates mild condensate exposure; upstream refrigerated/adsorption dryer is mandatory to control inlet humidity below 60% RH and extend service intervals.

Stainless steel anti-corrosion framework adapts to harsh humid industrial environments

Full stainless steel inner & outer cages resist rust and condensate corrosion, long service life under high-humidity workshop conditions; static conductive structure eliminates hidden ignition hazards in painting, chemical and food processing workshops.

Simple threaded maintenance design for single-person fast replacement

Isolate & vent housing pressure, unscrew top cap, extract old cartridge and install new unit within 2 minutes, minimizing unplanned large-scale production downtime.

Adsorption Working Principle

Trace gaseous oil vapor, hydrocarbon molecules and odor compounds are captured via physical adsorption on the microporous surface of activated carbon granules.

Purified oil-vapor-free compressed air (total residual oil ≤0.003 ppm) passes through the inner microfiber barrier and flows out to terminal production equipment.

After long-term service, carbon micropores become fully saturated with oil vapors; adsorption efficiency drops sharply and differential pressure rises. The cartridge cannot be regenerated on-site and requires complete replacement.
