The Krystal 5" Carbon Filter 125mm x 300mm is a compact 500m³/h air filter filled with 100% RC412 Australian virgin activated carbon for effective odour control in filtered extraction systems.
Combining a 125mm / 5" connection, 300mm filter body and 500m³/h airflow rating, this model provides effective carbon filtration in a relatively compact format. It is particularly useful where available installation space is limited but dependable odour filtration is still required.
Krystal Carbon Filters use 100% RC412 Australian virgin activated carbon. Its highly porous structure creates an enormous internal surface area, allowing odour-causing gaseous compounds to adsorb onto the carbon as extracted air passes through the filter.
A lightweight aluminium housing helps keep installation weight manageable, while the open-area mesh allows air to enter across the cylindrical filter surface before passing through the activated carbon bed.
Why choose the Krystal 5" Carbon Filter?
- 500m³/h airflow rating - suitable for compact filtered extraction systems.
- 5" / 125mm connection - matches commonly used 125mm fans, ducting and ventilation fittings.
- 300mm filter body - compact dimensions for installations where space is limited.
- 100% RC412 Australian virgin activated carbon - high-quality activated carbon selected for effective air filtration.
- Effective odour adsorption - captures unwanted gaseous odour compounds from extracted air.
- Lightweight aluminium housing - robust construction without unnecessary installation weight.
- Open-area mesh - provides a large surface through which air can enter the filter.
- Designed for filtered extraction - pairs with an appropriately specified extraction fan.
- Replaceable filtration component - replace the filter once the activated carbon eventually reaches the end of its effective service life.
100% RC412 Australian virgin activated carbon
The quality of the activated carbon is central to the performance of an odour-control filter. Krystal uses 100% RC412 Australian virgin activated carbon throughout this filter range.
Activated carbon is processed to create an extremely porous internal structure. These microscopic pores give the carbon an exceptionally large internal surface area relative to its physical size.
As extracted air passes through the carbon bed, suitable gaseous odour compounds adhere to the carbon surface through a process known as adsorption.
This makes activated carbon filtration fundamentally different from ordinary particulate filtration. Its primary purpose here is the removal of unwanted gaseous odour compounds from the extraction airstream.
500m³/h airflow capacity
This Krystal Carbon Filter is rated at 500 cubic metres per hour.
Fan and filter sizing should always be considered together. The carbon bed creates resistance, so a fan will not normally deliver its unrestricted maximum airflow once connected to the filter and ductwork.
Duct length, bends, reducers and other ventilation components add further resistance. Equally, forcing excessive airflow through a carbon filter can reduce the contact time between contaminated air and the activated carbon.
Correctly matching the fan, filter and ductwork helps provide effective ventilation while maintaining suitable conditions for carbon filtration.
Installing the Krystal 125mm Carbon Filter
A typical extraction arrangement draws air through the carbon filter before it reaches the extraction fan. The treated air then passes through the fan and into the exhaust ductwork.
- Support the filter securely and independently.
- Use 125mm ducting and fittings wherever practical.
- Pair with a fan appropriate for the 500m³/h filter rating.
- Keep duct runs short and direct where possible.
- Avoid unnecessary tight bends and reducers.
- Keep connections secure to minimise untreated air bypass.
- Keep the exposed mesh surface unobstructed.
Carbon filter life & replacement
Activated carbon has a finite adsorption capacity. During operation, odour compounds gradually occupy the available adsorption sites within the RC412 carbon.
Filter life depends on operating hours, airflow, contaminant concentration and environmental conditions, so there is no single replacement interval suitable for every installation.
If unwanted odours begin passing through despite correct airflow and secure ventilation connections, the carbon may be approaching the end of its effective service life.

Krystal 5" 125mm x 300mm Carbon Filter FAQs
What is the airflow rating?
The Krystal 125mm x 300mm Carbon Filter is rated at 500m³/h.
What activated carbon does this Krystal filter use?
It is produced using 100% RC412 Australian virgin activated carbon.
What does RC412 activated carbon do?
Its porous structure provides a very large internal surface area onto which suitable gaseous odour compounds can adsorb as extracted air passes through the carbon bed.
What size ducting should I use?
The filter has a nominal 125mm / 5" connection, so matching 125mm ducting and fittings should be used wherever practical.
What extraction fan should I use?
Select a compatible fan according to the filter's 500m³/h airflow rating, the required ventilation rate and resistance from the complete duct system.
Will the carbon filter reduce fan airflow?
Yes. The carbon bed creates airflow resistance, so installed fan performance will normally be lower than its unrestricted maximum airflow rating.
Can I use a variable-speed fan?
Yes. A suitable variable-speed fan allows airflow to be adjusted to the requirements of the filter and ventilation system.
Should the carbon filter go before the extraction fan?
A common configuration draws air through the carbon filter first and then through the extraction fan, treating the air before it enters the exhaust ductwork.
Why is fan and filter matching important?
The fan must provide enough airflow after system resistance is considered without forcing air through the carbon filter unnecessarily quickly.
Is the housing aluminium?
Yes. Krystal specifies a lightweight aluminium housing for its carbon filter range.
What is the purpose of the open-area mesh?
The mesh provides a large open surface through which air can enter the cylindrical carbon filter before passing through the activated carbon bed.
How long will the carbon filter last?
Service life varies according to airflow, operating hours, contaminant concentration and environmental conditions, so there is no single lifespan applicable to every installation.
How do I know when it needs replacing?
If unwanted odours begin passing through despite suitable airflow and secure connections, the activated carbon may be reaching the end of its useful adsorption capacity.
