Frequently Asked Questions – Scrubbers

Diesel and Gas Scrubbers

What this the difference between a scrubber and a purifier?

There is no difference, it is just a different name for the same thing.

How long do they last?

As long as you perform regular maintenance on your engine (clean the air filter, tune up, etc.) and run a low-sulfur diesel fuel, the diesel scrubbers will last you many years and may never need to be replaced.

Gas/propane scrubbers will last you a long time as well as long as you keep an eye on your air to fuel ratio and keep the engine maintained.

What do they do?

They make diesel and gas exhaust emissions legal and safe to breathe. This allows you to work indoors, close to a diesel or gas engine. The scrubbers minimize the health risk while working in close quarters with the machinery.

What is the warranty?

The scrubbers have a 1 year warranty which covers any manufacturers defects and includes evaluation of the scrubber to determine if its failure is the cause of any issues while operating the machinery.

I am in a hurry. What is your rush option? 

The Rush Option pushes your scrubber order to the front of the production line. The cost is $150 per scrubber and guarantees the scrubber will ship within 24-48 hours of the order.

Where are they made?

Our national engine center is in Worcester, MA.

Does a clip-on work as well as a combination muffler/scrubber combination?   Which one should I buy?

Yes, the clip-on works just as well as the combination muffler/scrubber. However, the closer the scrubber is installed to the manifold, the hotter it will run. You want it as hot as possible for optimal results.

Can you send me some general info?

Yes. What is your email address? (Diesel or Gas Scrubber ABCs)

Who certifies your scrubbers?

The scrubbers are certified by OSHA, MSHA and CARB.

Will they replace a Diesel Particulate Filter?

No, but they will remove up to 40% of the particulate matter in your diesel engine.

What maintenance is required?

The scrubber needs to be checked for particulate matter build up between 1000-3000 hours of operation. There is a baking process the scrubber can go through if it needs to be cleaned.

How will I know if it needs to be cleaned?

Use a CO monitor while operating your equipment. If the readings begin to increase, check the scrubber for any particulate matter build-up.

How do you clean them?

You can bake them in an industrial oven or kiln. This is similar to DPF cleaning and can be done at a local truck maintenance facility that performs DPF cleaning.

What do they weigh?

The weight of each scrubber varies as they are each custom made to order and the size depends on the horsepower of the machine. The most common scrubbers weigh less than 10 pounds.

What is the price difference of the combination muffler/scrubber vs. a clip-on?

The muffler/scrubber combo is about double what the price of the clip-on unit is.
