Education

Education is more important than the sale, without it no sale or project can be done with the proper product or equipment. When it comes to filtration we first must understand what is in the air from particle size & weight to what type of gases or odors we are controlling with filtration.

Vent Pipe Operation

The passive PVC Vent Scrubber filters eliminate polluted vent air through 8" of dry chemical media, which react with the odorous gases to form landfill-safe solid reaction products. Clean air is then discharged out the top of the scrubber through an open cap air ventilator. The PVC Vent Scrubber draws air inward through a sewer vent check valve that only allows air in and not out. This process allows for normal vent pipe DFU function to allow sinks, tubs, toilets and other water drainage to the sewer without building a positive or negative pressure in the vent pipe while still eliminating odors from vents.

About Our Filter Media

Vent Pipe Media

OdormixSP and Odorcarb Ultra: are UL-900 Tested and designed for broad-spectrum removal of sewage odors at 99.5+% efficiencies including mercaptans, hydrocarbons, hydrogen sulfide and sulfur dioxide. Spent media is safe for landfill disposal. MSDS information is available.

Our activated alumina media is designed for eliminating sewer gas, not only removing hydrogen sulfide (H2s) but other gases that cause odor problems.

Targeted Odors/Gases
Hydrogen sulfide	Ammonia	Organic compounds
Sulfur dioxide	Mercaptans	Aldehydes

Why Our Media Over Carbon?

Activated Alumina

New & Used Media is Non-Toxic & Safe for Landfills!

H2s Capacity’s

OdormixSP @ 12%
OdorcarbII @ 49%

Both media’s are UL Certified .

Our media is manufactured round and allows for better airflow through the media bed and helps to reduce pressure.

Activated Carbon

Used carbon is not safe for landfills!

Holds only 4% by weight of H2s.

Carbon is not UL Certified and can catch fire as lowasafs@afslasvegas.com 130 degrees.

Carbon is generally crushed and fits like puzzle pieces which restricts airflow through the media bed.


	4%, what does that mean?		Most carbon vent filters on the market hold about 1/2 pound of carbon or less, this means they will hold only 0.02 pounds of H2s and they need to be replaced. It would take 12 of our compedators vent filters to remove what our smallest vent scruuber will remove in H2s. For our 4" Plus it would take 30 of our compedators vent filters to equal our 4" Plus vent scrubber.

Activated Carbon

Notice

We have found some companies using BBQ Briquettes as a filter media. Although this is carbon it is also manufactured to be very flammable, do not use it!

Vent Pipe Filtration Warning

Vent pipe filtration is a good way to remove unwanted odors from vents.Please note that if your plumbing pipes are installed correctly with no leaks our sewer or grease vent filter will work correctly. If you have any leaks in your plumbing pipes, using any vent filter will cause odors to bleed out your unsealed plumbing pipes. These leaks should be fixed if you use vent pipe filters or choose not to use them. If you continue to have odor problems you can contact us by emailing your problem in full and we will review it and get back to you.

Installations

Note that our scrubbers are installed below the roof wall & next to the units they are protecting. We STOP the odors. You do not need any pipe extensions when using our scrubbers.
