Maxi Filtra Installation Instructions

The Studor Maxi-Filtra is a sturdy, active carbon vent designed specifically for outdoor applications to eliminate bad odours produced by the drainage system, and is ideal for use with septic tanks. Robust design means the Maxi-Filtra can be used externally, either vertically or horizontally, and can be installed in hard-to-reach places.

The active carbon filter within the Studor Maxi-Filtra operates as a two-way vent, filtering air in both directions and absorbing the bad odours. The Studor Maxi-Filtra is packaged in a resilient exterior for longevity outside, together with an initial replaceable filter.

The Studor Maxi-Filtra may be installed externally anywhere when the odour from existing vents present a problem, or when pipe vents are to be included in the drainage system of a new build:

• Septic tanks

• Grease separators

• Rain water tanks

• Sewage treatment plants

Key features and benefits:

• Saves money by eliminating the need for odour-reducing additives in septic tanks.

• Easy retrofit installation to solve existing problems.

• Simple push-fit connection to all brands of UK domestic soil pipe.

• Designed to resist extreme temperatures and deterioration.

• Low maintenance – just replace the carbon cartridge a minimum of every two years; the Maxi-Filtra cap simply lifts off.
