Master Vent

Master Vent Holding Tank Odour Filters

Sewage holding tanks need to be vented. The best way for your waste tank to breathe and remove the bad smell known as Hydrogen Sulfide (H2S) is to have a quality impregnated Activated Carbon filter in the vent line. Master Vent is purpose made for maximum removal of H2S odours.

Master Vent is an industrial grade OxPure Activated Carbon filter that is impregnated with Potassium Hydroxide (KOH). This is the same impregnated Activated Carbon used in commercial municipal sewage treatment plants in Australia, USA & Europe.

Australian made and designed for easy installation by having a multiple staged tail for different size hoses 16mm-5/8" 19mm-3/4" 25mm-1" 38mm-1 1/2".

Master Vent comes with a mount kit, but for easy change over it will also fit into other brand brackets like Sealand, Dometic, Airforce etc.

Filled with 350 grams of OxPure industrial grade impregnated Activated KOH Carbon makes Master Vent one of heaviest and longer lasting odour filters on the market.

Don't be fooled, there is a difference..

Master Vent uses a quality industrial grade OxPure 4B-KOH Activated Carbon that is impregnated with Potassium Hydroxide. Made specifically for removing the maximum amount of H2S odours.

Most other brands use a standard Non impregnated carbon. The same commonly used in fish tank filters.
