CA Gas-Phase
Chemical Air Filtration

Industrial-grade activated carbon & chemical media from Createch-Asia. 10 specialized series (CA-1000 → CA-10000). 9 equipment formats. Critical DC infrastructure — prevents H₂S, SO₂, NOₓ, HF, HCl, NH₃, O₃, Cl₂, VOC, bacteria, and dust from corroding hard disks, network gear, storage, and cabling.

CA series filtration media — 10 formulations from CA-1000 to CA-10000

Air is chemistry, not just temperature

ASHRAE TC 9.9 and ANSI/ISA 71.04-2013 define gas-phase contamination severity in data centers. The wrong air chemistry quietly destroys copper circuits, silver solder, and gold connector plating — long before any temperature alarm fires.

G1
Mild

Monitored monthly. Most greenfield sites start here. Acceptable for general IT.

G2
Moderate

Visible creep corrosion within 1–2 years on copper. Filter upgrade recommended.

G3
Harsh

Hard drive failures within months. Switch port degradation. Cable jacket embrittlement.

G4
Severe

Unacceptable for IT equipment. Process control rooms, refinery, smelter adjacencies.

CA-1000 → CA-10000

Each series is a chemically distinct activated-carbon or impregnated-media formulation, selected by target pollutant and operating environment.

CA-1000
Bacteria / microbes

Kill various bacteria and inhibit bacterial regeneration. Impregnated with antimicrobial agents. For white spaces, hospitals, pharma clean rooms.

CA-2000
Acidic + organic gases (aldehyde, benzene)

Remove various acidic gases and organic VOCs including aldehyde and benzene. For office buildings, museums, archives, new-construction fit-out.

CA-3000
Sulfides · NOₓ · O₃ · VOC

Filtration of sulfide, nitrogen oxides, ozone, VOC and other airborne pollutants. Workhorse formulation for urban data centers near traffic corridors.

CA-4000
Sulfides · chlorides · HCl · HF

Targets acidic gases including sulfides, nitrogen compounds, chlorides, hydrogen chloride, hydrogen fluoride. Industrial adjacencies — chemical plants, pickling lines.

CA-5000
Cl₂ · HCl · drying

Chlorine, chloride, hydrogen chloride, and other halides. Doubles as a desiccant for humidity-sensitive environments. Pool halls, water-treatment DC sites.

CA-6000
NH₃ · PH₃ · N₂H₄ (alkaline)

Ammonia, phosphine, hydrazine and other alkaline gases. Impregnated for acid-gas neutralization of base pollutants. Wastewater, agriculture, refrigeration.

CA-7000
Complex-environment odors

Remove various odors in complex, mixed-pollutant environments. Broad-spectrum formulation — kitchen exhaust, mixed manufacturing, composting facilities.

CA-8000
Living-space odors + VOCs

Remove odor and volatile gas in living atmospheric environments. Office-grade IAQ (indoor air quality). Smoking lounges, gaming centers, hotel corridors.

CA-9000
High-temp + humid environments

Odor and integrated gas filtration in high-temperature and humid environments. Engineered to retain adsorption capacity above 80% RH and 40°C.

CA-10000
Methanol · ethanol · humidity control

Remove methanol, ethanol, and other alcohol-class volatiles. Doubles as humidity buffer. Pharma labs, semiconductor wet benches, museum-grade archives.

Engineered to fit any airflow architecture

Same CA media, nine deployment formats — wall, ceiling, in-duct, fan-filter, modular. New build, retrofit, edge, or temporary — there's a format.

CA-WFS
Wall-mounted Fresh-air System

Self-contained wall unit, recirculating or fresh-air. Plug-in install, no ductwork. Small server rooms, edge DC, telecom shelters.

CA-CFS
Ceiling-mounted Fresh-air System

Concealed above-ceiling install. Quiet operation. Office-grade IAQ with low visible footprint.

CA-AFS
Air-handling Filtration System

In-line module for AHU integration. Targets the full supply-air stream at the central plant. New DC builds.

CA-EFS
Exhaust Filtration System

Treats exhaust air before discharge. Required for adjacent-building odor complaints, chemical laboratories, semi-corrosive processes.

CA-HFS
High-flow Filtration System

Large central-station configuration. Targets hyperscale and colocation halls with CFM requirements > 50,000.

CA-FFU
Fan Filter Unit

Ceiling-grid FFU with HEPA + CA chemical stage. Class 1,000–10,000 cleanroom-grade. Optical storage, semiconductor back-end.

CA-APS
Air Purification System

Standalone indoor purifier. Recirculates and treats IAQ in occupied rooms. Hospital wards, hotel suites, executive briefing rooms.

CA-USAH
Unit Self-contained Air Handler

Modular air handler with integrated CA chemical stage + cooling + filtration. Single-skid deploy for retrofit projects.

CA-MC
Modular Cabinet

Floor-standing cabinet with CA modules. Plug into the data-hall cold-aisle, side-stream extraction. Hot-spot remediation without shutting down the hall.

Typical site profiles

Selected based on air-chemistry severity (ISA 71.04 G-rating) and adjacent-activity risk — not generic AC sizing.

DC

Data centers (G2–G4)

Hard-disk corrosion mitigation, switch port reliability, cabling lifespan extension. Mandatory for greenfield IDC near industrial zones, heavy-traffic corridors, or coastal salt exposure.

SM

Semiconductor back-end

Outgassing control in die-bond, wire-bond, and packaging halls. CA-10000 series handles alcohol-class solvents from wet-bench operations.

PH

Pharma & life-science labs

Cross-contamination control in BSL-2/3 labs, cleanrooms, IVC racks. CA-1000 antibacterial series paired with HEPA particulate stage.

MA

Museums & archives

Acidic gas + VOC scrubbing for paper, textile, photographic, and film collections. CA-2000 and CA-10000 series are the standard UNESCO/ISO 11799 references.

WW

Wastewater & chemical plants

H₂S, NH₃, and chloramine scrubbing at lift stations and pump rooms. Adjacent control rooms protected to ISA 71.04 G1.

HO

Hotels, offices, hospitality

IAQ uplift in guest rooms, gaming floors, F&B exhaust points. CA-7000 and CA-8000 series — broad-spectrum odor and VOC neutralization.
