What others say about us

We are extremely happy with the performance thus far and are impressed with our results. Our DPF out measurements for the CO is 0 as well as the smoke number dropping from an 8 to 0 on the outlet side.

We would normally see a blue haze in that area of the mine.  The air was clear with your catalytic converter on the generator.

Mine Maintenance Manager

Back in 2010 we were given a citation for an lt210 loader being over 160 microgram per cubic meter of air. We changed the original scrubber that was not damaged and put an air flow catalyst one on.  The original measure were 181 microgram per cubic meter. With the air flow on we had 28 micrograms for an 8 hour shift which is very impressive.
