Oltaven Ozone Removal Filter – Aluminum Honeycomb Catalytic Filter

Oltaven ozone removal filters are finished catalytic filters built on an aluminum honeycomb carrier coated with a proprietary ozone-decomposing catalyst. They convert ozone in air streams into oxygen and are used in commercial air purifiers, laser printers, copiers, ozone disinfection equipment and medical exhaust outlets. This page explains how media choice and forming decide efficiency, resistance and capacity, and how Oltaven delivers finished filters – not just media – to OEM and ODM customers.

From Media to Finished Filter

A finished filter is more than a sheet of catalyst-coated media. The aluminum honeycomb substrate is coated with the catalyst, cut to the required thickness, and then framed or edge-sealed to fit the device. Each step affects how the filter performs in service. The honeycomb structure gives a large catalytic surface in a shallow depth, so ozone contacts the catalyst as air passes through. The catalyst formulation determines how quickly ozone is converted. Cutting and framing determine whether air takes the intended path or bypasses the media. Oltaven supplies the complete finished filter, so the customer receives a part that is ready to install and has been checked for fit and function.

What Decides Finished Performance

Three factors decide the finished filter’s efficiency, resistance and capacity: the catalyst, the honeycomb geometry and the frame or seal. The catalyst is the active component. Oltaven uses a patented catalyst (patent number ZL200710026260.6) that decomposes ozone on contact. Because the catalyst works at the surface, a uniform coating matters more than a thick coating; excess coating can block airflow without adding useful activity. The honeycomb geometry sets the balance between contact time and pressure drop. Thicker honeycomb gives more contact time but higher resistance; thinner honeycomb reduces resistance but may shorten the effective contact path. Oltaven cuts aluminum honeycomb to various thicknesses so the filter can be matched to the device’s airflow and space. Finally, the frame and edge seal keep air from bypassing the honeycomb. Oltaven offers aluminum alloy frames and sponge or EVA sealing strips to maintain installation airtightness. A filter that fits poorly can show low efficiency even when the catalyst is good, because untreated air escapes around the edges.

These choices also affect capacity and service life. A filter that is correctly matched to the airflow loads the catalyst evenly, while an oversized or undersized filter may load unevenly and lose performance sooner. Oltaven’s approach is to select the catalyst, honeycomb thickness and frame together for each application, then verify the finished part. The result is a filter whose efficiency, resistance and capacity are decided by design rather than by media alone.

Applications

Oltaven ozone removal filters are used where ozone is generated as a by-product or as a process gas. Typical installations include high-voltage electrostatic air purifiers, large laser printers, commercial copiers, ozone disinfection equipment (tail-gas treatment) and medical device exhaust outlets. In these devices, the filter is placed in the air path after the ozone source, so that treated air is released to the room or duct. The filter can also be combined with other filter stages in commercial air handling and ventilation systems. Because the finished filter is custom-sized, it can be integrated into new equipment designs or used as a replacement part in existing devices.

Products comply with REACH and RoHS environmental regulations, and compliance documents are available.

OEM/ODM Workflow

1. Inquiry and application review: share the device model, size or drawing, airflow, operating conditions and target quantity.
2. Solution proposal: Oltaven recommends catalyst, honeycomb thickness, frame and sealing options for the application.
3. Sample development: samples are produced for fit and performance evaluation; sample lead time is about 10–15 days.
4. Validation and approval: the customer tests the sample in the device and approves the specification.
5. Production: batch manufacturing follows the approved specification, with IQC, IPQC and OQC checks.
6. Delivery: standard products ship in 7–10 days; OEM/ODM batch orders typically take 25–35 days.
