Frequently Asked Questions
What is the format actually for?
Adding gas-phase treatment to existing plant.
It drops into a standard filter track.
No separate housing or ductwork is needed.
Servicing looks like any other filter bank.
For a retrofit it is often the only option.
That convenience is what is being bought.
What is given up against a deep bed?
Media volume, and therefore life.
A cassette holds only what its frame depth allows.
Contact time is shorter as a result.
Beds can run for years.
Cassettes are often annual or seasonal.
Establish that recurring cost first.
Which dimension matters most?
Depth, because it holds the media.
Deeper cassettes give more contact time.
Face velocity stays the same.
Available track depth usually decides.
Measure the unit before selecting.
Adaptor frames exist but cost depth.
Is particulate pre-filtration necessary?
More so here than elsewhere.
Dust blinds the media surface.
That blocks access to the internal area.
A blinded cassette wastes the whole module.
Cassettes cost far more than a pre-filter.
Protect them upstream.
How is change interval decided?
By predicted loading, not by pressure.
Saturation barely changes resistance.
Concentration and airflow give an estimate.
Media sampling confirms remaining capacity.
Odour breakthrough is the crude fallback.
By then it has already failed.
Does the media choice differ from other formats?
No, it follows the target gas as always.
Plain carbon suits many organic vapours.
Impregnated media handles specific inorganics.
Blends address mixed contaminants.
Name the gas before ordering.
Format and media are separate decisions.
What about disposal?
It depends on what has been adsorbed.
Spent media holds the captured contaminant.
Some are classified as regulated waste.
Industrial applications need this checked.
Odour-only duties are usually straightforward.
Confirm before the first change is due.
