Air Filters
activated carbon air filter roll
| Brand | shengtongJH |
|---|---|
| Material form | Activated carbon bonded to polyester nonwoven media |
| Roll width options | 1000 / 1250 / 2000 mm, according to construction |
| Length options | 20 m or cut length; longer rolls subject to thickness and packing |
| Thickness options | 3 / 5 / 10 mm nominal nonwoven constructions |
| Cut format | Rectangular pads, strips or agreed die-cut shapes |
| Supporting arrangement | Retaining grid, cassette or compatible rigid frame |
| Carbon loading | Specified per unit area for the selected media grade |
| Airflow direction | As required by the selected backing and media construction |
| Performance basis | Gas-specific capacity and resistance at the agreed face velocity |
| Storage | Sealed protective wrapping in a dry area away from contaminant sources |
Widths, thicknesses and lengths are selectable formats rather than a claim that every combination is stocked. Carbon loading and resistance must refer to the specific ordered media.
Roll width, cut length, pad dimensions, backing and packing can be customized to the industrial filter holder and conversion process.
An activated carbon air filter roll provides carbon-bearing flexible media for cutting into replacement pads or assembling supported filter panels. This page covers activated carbon bonded to synthetic nonwoven material, not woven activated-carbon fibre cloth or a loose-carbon refill.
Buy for the cutting pattern
Roll media can reduce waste when a maintenance team replaces many pads of the same size. Start with the finished pad dimensions and the usable roll width, then work out how the shapes will be nested. Allow for the holder's required edge engagement; a pad cut only to the visible opening can leave gaps around the perimeter.
For mixed equipment sizes, keep an identified cutting schedule. Mark the intended holder and direction before installation rather than asking technicians to choose a piece by appearance. A correctly sized spare is useful only when its construction also matches the intended air service.
Support the media without crushing it
A flexible sheet is not a self-supporting filter. Provide a suitable grid or cassette so suction does not pull it away from the sealing edge. Avoid compressing a thick pad into a shallow holder: compression can alter airflow resistance and make the closure uneven.
Check the selected material's handling instructions before cutting, bonding or pleating it. A carrier designed for flat-pad use should not automatically be treated as a pleatable manufacturing material.
Know the capacity of a thin layer
A carbon-bearing mat can suit space-limited odour treatment, but its available sorbent mass differs from a deep granular bed. Adding more layers also adds resistance. For a sustained or high contaminant load, compare a purpose-designed deeper assembly instead of stacking pads until the fan struggles.
Keep unused material protected
Carbon can take up contaminants during storage as well as during operation. Reseal the unused roll and keep it away from solvents and strong odour sources. Protect the edges from abrasion and retain the material identity with the cut pads.
Do not use colour or dust accumulation as the only replacement indicator. The gas-treatment capacity can be depleted without a large pressure rise. Agree a service plan appropriate to the contaminant and operating pattern. shengtongJH can source the roll and conversion format against that duty; a broad claim of removing every gas is not a useful specification.
