The OdorHog Metal Cap is a Louvered, Galvanized Steel cap that offers excellent venting capability. It is the top choice for aesthetics on the roofline and many times, matches or compliments other ducting and venting that is existing on the roof.
Like all of our OdorHog septic odor filters, the OdorHog Metal Cap filter is available in White PVC or Black ABS. We recommend the ABS models for Northern US and Other Locations where sub-zero temps are likely.
The plastic slip on models need no tools or glue to install – they slip right on the vent pipe on the roof. If you have metal or cast iron pipes choose a Clamp-on model. A flathead screwdriver or a 5/16" nut driver is all you'll need to install this unit.
Each OdorHog has a replaceable mesh bag inside the body, with pelletized charcoal that is activated for the H2S molecule. Changing your charcoal out has never been easier and can be done while the OdorHog remains on the vent pipe! Just remove the cap, pull the old charcoal bag out by the handle and put the new bag in and put the cap back on. Fresh charcoal in minutes!
Our Commercial grade charcoal is made from a coconut shell based carbon that has a higher sewer gas absorption capacity and is made for longer life. It is perfect for heavy hydrogen sulfide applications.
OdorHogs are designed for passive or ambient air flow and are not suitable for applications where blowers or fans push or force air.
When choosing the correct size, measure the OUTSIDE DIAMETER of your existing vent pipe.
Our Black ABS plastic is recommended for areas that experience freezing temperatures. Otherwise you can choose based on color preference.
Our slip-on connections fit snugly on standard ABS/PVC vent pipes and no tools or glue are needed for installation. Our clamp-on connections are for use on cast-iron pipe or non-standard ABS/PVC vent pipe.
Our Commercial Grade charcoal is made from a coconut shell based carbon. It is longer lasting than coal based charcoals and can absorb up to 4 times longer.
