The U-GO Carbon Filter 12.5" 315mm x 600mm is a large-diameter activated carbon air filter built around carefully selected Pro Grade 4/8 carbon, combining effective odour adsorption with high airflow and low restriction.

Activated carbon is a natural material, which means its quality, particle characteristics and adsorption performance can vary from batch to batch. U-GO takes a selective approach to the carbon used inside its filters, stating that it purchases only the premium 20% of carbon produced.

The carbon is independently batch tested, de-dusted and selected before use. U-GO specifies Pro Grade 4/8 activated carbon, with material that is excessively fine, dusty or fails its required air-stream testing rejected rather than used within the finished filter.

With a substantial 315mm / 12.5" connection and 600mm filter body, this model is designed for high-airflow extraction systems where effective odour control needs to be combined with minimal unnecessary airflow restriction.

  • Low-restriction filtration - particularly important in large-volume extraction systems.
  • 315mm / 12.5" connection - integrates with compatible high-airflow fans, ducting and ventilation fittings.
  • 600mm filter body - substantial filtration capacity in a relatively compact large-diameter format.
  • Effective odour adsorption - activated carbon captures suitable gaseous odour compounds from extracted air.
  • Designed for high-airflow filtered extraction - suitable for pairing with an appropriately specified 315mm extraction fan.

Premium selected Pro Grade 4/8 carbon

Carbon quality has a major influence on the performance of an activated carbon filter. Natural carbon can vary in particle size, dust content and adsorption capability, so U-GO places particular emphasis on selecting the material used inside its filters.

U-GO states that it purchases only the premium 20% of carbon produced. The selected carbon is independently batch tested, de-dusted and checked before being used within the finished filter.

The U-GO range uses Pro Grade 4/8 activated carbon. Particle characteristics are important because the carbon bed needs to provide extensive adsorptive surface area while still allowing large volumes of air to travel through efficiently.

Carbon that is excessively fine or dusty can create unnecessary resistance. U-GO's selected 4/8 grade is intended to achieve an effective balance between odour filtration and airflow.

Independently batch tested carbon

U-GO states that its activated carbon is independently batch tested rather than assuming every batch of natural carbon will perform to the same standard.

The selection process assesses the carbon for characteristics required for effective air filtration, with U-GO specifying a minimum 20% butane adsorption requirement.

Carbon that is too small, excessively dusty or does not meet the required air-stream testing standard is rejected rather than being used within the finished filter.

This quality-control approach is intended to provide more consistent filtration and airflow performance throughout the U-GO carbon filter range.

How activated carbon removes unwanted odours

Activated carbon contains an enormous network of microscopic pores. These create a very large internal surface area relative to the physical volume of carbon inside the filter.

As odour-bearing air passes through the carbon bed, suitable gaseous compounds adhere to the carbon surface through a process known as adsorption.

Carbon quality, airflow, contact time, environmental conditions and contaminant concentration all influence the effectiveness of this process.

The U-GO filter is therefore primarily designed to treat gaseous odour compounds carried within extracted air rather than simply acting as a dust or particulate filter.

Designed for high airflow with low restriction

Airflow resistance becomes particularly important in a large 315mm ventilation system. Even a powerful extraction fan can lose significant airflow when resistance is introduced by a carbon filter, long duct runs, bends, silencers and other components.

U-GO's use of selected Pro Grade 4/8 carbon is intended to provide effective adsorption without unnecessarily restricting the movement of air through the carbon bed.

The filter's large 315mm / 12.5" connection also allows it to form part of a high-volume ventilation system without immediately forcing the airflow through a smaller-diameter connection.

Maintaining the 315mm diameter through as much of the ventilation system as practical helps minimise additional resistance and allows the extraction equipment to operate more efficiently.

315mm / 12.5" connection with 600mm body

This U-GO Carbon Filter combines a nominal 315mm / 12.5" connection with a 600mm filter body.

The large diameter makes it particularly suited to high-airflow ventilation installations where smaller duct sizes would create excessive air velocity and resistance.

Using matching 315mm ducting, fans and fittings wherever practical provides the most direct airflow path through the system.

If reducers are required, they should be considered carefully because a significant reduction in duct diameter can increase resistance, turbulence and airflow noise while reducing overall system performance.

Installing the U-GO 315mm Carbon Filter

In a typical filtered extraction system, environmental air is drawn through the carbon filter before entering the extraction fan. The treated air then continues through the exhaust ductwork.

Fan and filter performance should be considered together. A high-capacity extraction fan needs sufficient static-pressure capability to overcome resistance from the carbon bed and the remainder of the duct system while maintaining the required airflow.

  • Support the carbon filter securely and independently.
  • Use 315mm ducting and fittings wherever practical.
  • Match the extraction fan appropriately to the filter and required airflow.
  • Keep duct runs as short and direct as the installation allows.
  • Minimise unnecessary tight bends and reductions.
  • Secure all connections to minimise untreated air bypass.
  • Keep the filter's air-entry surface unobstructed.
  • Allow sufficient space around the filter for unrestricted air entry.

Carbon filter life & replacement

Activated carbon has a finite adsorption capacity. As contaminated air passes through the filter, gaseous compounds progressively occupy the available adsorption sites within the carbon.

U-GO's selected carbon and low-restriction design are intended to provide effective filtration and a longer expected operating life, but actual service life depends heavily on operating conditions.

Operating hours, airflow, environmental conditions and the concentration of odour compounds being treated can all affect how quickly the activated carbon becomes saturated.

If unwanted odours begin passing through despite suitable airflow, correct installation and secure connections, the carbon may be approaching the end of its effective adsorption capacity.

U-GO 12.5" 315mm x 600mm Carbon Filter FAQs

What size is this U-GO Carbon Filter?

This model has a nominal 315mm / 12.5" connection and a 600mm filter body.

What type of activated carbon does U-GO use?

U-GO specifies selected Pro Grade 4/8 activated carbon for its carbon filter range.

What does Pro Grade 4/8 carbon mean?

It refers to the selected particle grade used inside the filter. Carbon particle characteristics influence both adsorption performance and resistance to airflow through the carbon bed.

Why does U-GO select only part of its carbon supply?

Activated carbon is a natural material and its characteristics can vary between batches. U-GO states that it selects only the premium 20% of carbon produced for use within its filters.

Is U-GO activated carbon batch tested?

Yes. U-GO states that its carbon is independently batch tested, de-dusted and selected before being used in its filters.

What is the minimum 20% butane adsorption specification?

U-GO specifies a minimum 20% butane adsorption requirement as part of its carbon quality testing, with material that fails the required standard rejected.

Why does activated carbon particle size matter?

Particle characteristics influence both adsorption and airflow through the carbon bed. Excessively fine or dusty carbon can create unnecessary airflow resistance.

Does U-GO de-dust its carbon?

Yes. De-dusting forms part of U-GO's stated carbon selection and preparation process.

What size ducting should I use?

This filter has a nominal 315mm / 12.5" connection, so matching 315mm ducting and fittings should be used wherever practical.

Can I use this filter with a 315mm extraction fan?

Yes. It is designed for integration into a 315mm ventilation system. The fan and filter should also be appropriately matched for the required airflow and resistance of the complete system.

Will a carbon filter reduce extraction airflow?

Yes. Every carbon filter creates some resistance. U-GO's selected carbon grade is intended to maintain strong airflow while providing effective activated carbon filtration.

Can I reduce the 315mm connection into smaller ducting?

A suitable reducer can be used where necessary, but reducing duct diameter increases air velocity and system resistance and can reduce overall airflow.

How does the U-GO Carbon Filter remove unwanted odours?

Odour-bearing air passes through the activated carbon bed, where suitable gaseous compounds adsorb onto the enormous internal surface area of the carbon.

How long does a U-GO Carbon Filter last?

Service life depends on operating hours, airflow, contaminant concentration and environmental conditions, so there is no single replacement interval suitable for every installation.

How do I know when the carbon filter needs replacing?

If unwanted odours begin passing through despite correct ventilation operation and secure connections, the activated carbon may be approaching the end of its effective adsorption capacity.
