ePUR CA professional air purifier
The ePUR CA is a professional mobile air purifier designed to treat gaseous pollutants: VOCs, solvent vapors, industrial odors, and chemical fumes. It operates by activated carbon adsorption, a process that standard HEPA filtration does not cover.
Activated Carbon: The Game-Changer
Most air purifiers retain solid particles: dust, fumes, aerosols. They are ineffective against gaseous pollutants.
The ePUR CA incorporates activated carbon cartridges that work by adsorption: gaseous molecules attach to the microporous surface of the carbon and remain trapped there. This mechanism is the only one capable of effectively treating VOCs, solvent vapors, and olfactory nuisances.
The ePUR CA specifically treats:
- Organic solvents from painting, varnishing, degreasing, and cleaning processes: hexane, cyclohexane, trichloroethylene, toluene, xylene, acetone, MEK, glycol ethers, THF.
- Pollutants from bonding: neoprene glue vapors, hardeners, and setting accelerators.
- Persistent industrial odors in the atmosphere.
- VOCs released by agri-food, chemical, textile, and wood processing operations.
Cartridges are selected based on the target molecule. Similarly, the type of activated carbon varies depending on the pollutant to be adsorbed.
Three Models, Custom Sizing
[table “236” not found /]All models are equipped with a potentiometer allowing flow adjustment from 0 to 100%. The number of air changes per hour is adjusted according to pollutant concentration, the area to be treated, and the expected result.
The circulation principle is identical across the entire range: polluted air is drawn in from the top of the unit, passes successively through the filtration stages, and is then discharged purified at ground level. The slightly warmer air drawn in from above descends, creating a continuous circular movement and treating the entire volume. With each pass, between 80% and 99.995% of pollutants are captured, depending on the filter configuration chosen.
Two Modes of Use Depending on Your Situation
Ambient Air Treatment
The ePUR CA operates autonomously in the heart of the workshop or workspace. It captures gaseous pollutants that cannot be extracted at the source: suspended VOC residues, persistent odors, diffuse vapors. This mode is often used in conjunction with existing source extraction.
Source Capture
Equipped with an extraction arm, an extraction hood, or connected directly to a machine or suction table, the ePUR CA captures pollutants at the emission point, before their dispersion in the workshop. The cover and arm are easily removable to switch to ambient mode as needed.
OEL Compliance: A Legal Obligation, Concrete Protection
The Labor Code requires all employers to maintain chemical pollutant concentrations below the Occupational Exposure Limit Values (OELVs) set by Decree No. 2024-307. These thresholds directly concern VOCs, solvents, and CMR products handled in industrial workshops, laboratories, and production areas.
The ePUR CA helps bring ambient concentrations below these regulatory thresholds. It protects operators exposed to gaseous pollutants over time and reduces the risk of infringements during occupational health or labor inspection controls.
Application Sectors
Recommended use is strictly professional. ePUR CA air purifiers are deployed in various sectors:
- Industry: metallurgy, plastics, chemicals, agri-food, textiles, wood industry, paper and cardboard, waste collection and recycling, art restoration.
- Medical and Paramedical Sector: hospitals, nursing homes, dental practices, dental prosthetists, laboratories, veterinarians, podiatrists, funeral homes.
- Public Access Establishments: communities, nurseries, schools, hair salons and nail bars, open-plan offices and offices near industrial zones.
Commissioning and Maintenance
Plug & play.
The device plugs into a standard electrical outlet. No ducts, no assembly, no prior intervention.
Mobility.
The ePUR CA is mounted on wheels. It moves freely according to production needs or workshop configuration.
Quick Maintenance.
Changing filter media and activated carbon cartridges takes 5 minutes, using a single hex key. No particular technical skill is required.
Controlled Consumption.
An ePUR CA with 10,000 m³/h consumes 750 W, which is 10 to 20 times less than an industrial extraction system of equivalent flow.
How to Choose the Right Activated Carbon for Your Problem?
Activated carbon is not a generic material. Its effectiveness depends on its porosity, specific surface area, and potential chemical impregnation. It should be noted that all these parameters vary depending on the molecule to be treated.
Activated carbon selected for toluene is not optimal against formaldehyde. Unimpregnated activated carbon is less effective against acids and bases.
Obera technicians identify the pollutant(s) present on your site, then select the appropriate cartridge from the available range. This step directly determines the device’s performance and the lifespan of the cartridges.
