This sewage treatment plant comes with a gravity outlet and is suitable for dwellings with up to 6 people or a 4 bedroom house. Marsh sewage treatment plants are widely regarded as the most efficient, reliable and economical domestic systems on the market.

Features:

  • Tested to BSEN12566:3 and CE-marked to ensure compliance with latest environmental and Building Regulations requirements
  • Class-leading effluent quality of 11.5:19.2:8.4 (BOD:SS:NH4 ) ensures discharges well within national consent standards
  • Three chamber system correctly sized for separation and retention of solids improves final effluent quality
  • Standard or shallow options enable suitability for all site conditions (including driveways - subject to plinth/surround to prevent superimposed loadings)

  • Low energy compressors ensure minimal running, maintenance and servicing costs
  • High specification bio-media (310m3 per m2 ) and membrane diffusers ensure even circulation to eliminate 'dead spots'
  • Internal recirculation (from final to primary chamber) continues treatment process to provide higher effluent quality whilst balancing flow over 24 hour period or periods of intermittent use
  • Integral lifting eyes for improved on-site handling
  • Unique 'keying-in' lip to assist anchoring into granular or concrete surround
  • Optional extras include patented Polylok filter to further reduce suspended solids and extend the life of drainage field; extensions for deep installations; pumped outlets for sites with adverse levels; and many more

Great Air Filter
Size: 9.6" x 11.1" x 2.2"
Some review’s will say “it’s an air filter, blah, blah, blah”. These reviews are written by the same people that think “water is water”. I’m not one of those people. I’ve noticed that the air smells better, cleaner. I’ve also noticed that the air blows a little stronger. It’s very easy to install, fits perfectly and it’s reusable so it saves you money over the long term and it reduces landfill waste.

THE cabin air filter to use!
Size: 9.6" x 11.1" x 2.2"
I replaced the OEM cabin air filter when I bought my truck, like I always do. 2019 & 2020 Ram 1500's suffer from an underperforming AC system in the summer due to a blend door in the dash not closing completely. Having any kind of restrictive cabin air filter only exacerbates the problem. I bought this filter on the recommendation of many owners who had done the same with great results. I was presently surprised at the increase in air flow coming out of the vents. I also like that in K7N fashion, it is washable and reusable, effectively making it a lifetime filter. Don't overthink it. Yes it costs more, but you will save $$ in the long run with this filter. I am sure this filter fits many other makes & models of vehicles and will improve the airflow of any vehicle it is installed in.

Easy to install and fits great
Size: 9.6" x 11.1" x 2.2"
Fits great and seems better quality than any paper filter. Nice rubber edge makes a good seal and the airflow is good. Used in a 2023 Ram 3500. Installation was easy. So far it appears to filter out all the dust and odors.

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!
