Filter fresh engine

Air filters may be a small component in the overall makeup of a piece of equipment, but they serve a very important role in helping your machine run smoothly and efficiently.

“Clogged air filters consume more fuel,” says Dennis Grieve, “and they have to be replaced more often.”

A heavy equipment operator and mechanic most of his adult life, Grieve has seen the damage a plugged air filter can do to machinery. Yet, he didn't feel there was an effective way to keep them clean.

So rather than risk damaging an air filter by banging it on the ground or holding an air nozzle ¼ inch away from the filter (which can tear it), Grieve developed the Air Filter Blaster.

“This tool provides enough airflow via a centrifugal forced-air induction chamber positioned inside an air filter to allow dirt and dust to dislodge thoroughly and safely from the air filter during the cleaning process,” he explains.

Due to its air-ride technology, there are no ball bearings, no needle bearings, or grease.

“At 135 psi, this bearing is doing 2,700 rpm inside the filter element,” Grieve says. “Not only have you sealed the filter element, you're also not allowing any dirt to get back inside. Even if you went up to 200 psi, the air jackets never let any more than 48.2 pounds come out of any one of the air jackets.

“It's going so fast you never have a direct blast of air to damage the filter cleats and elements,” he says.

Generally within 30 to 45 seconds, the air filter is clean, and you're ready to go back to saving fuel.

“If you have a 600-hp. engine, the Air Filter Blaster will save you as much as 5 gallons of fuel per hour. In a 12-hour shift, that's going to give you a savings of about 60 gallons of fuel, or about $250 in fuel savings in a day,” notes Grieve.

This technology lowers fuel costs and reduces the number of air filters being thrown away each year. In fact, Grieve says you can get 20 times the life out of your original filters.

Testing a theory

To test his invention, Grieve has conducted a variety of field trials, including one with Rusty Schwinn of Performance Service and Repair.

“We took two John Deere 7750 machines,” Schwinn says. “We installed brand-new filters and ran the two tractors the exact 12-hour day, doing the exact same job in the same field. The following morning, we cleaned out one of the filters with the Air Filter Blaster and got over 4.5 pounds of dirt out of the filter.”

The air filter in the other machine was left untouched.

“At the end of the second day, the one that did not have the filter cleaned out used 58 gallons more fuel than the one that did get cleaned with the Air Filter Blaster,” he notes.

Schwinn then cleaned the filter that hadn't been cleaned the day before, and he got just over 5 pounds of dirt out of it.

“After one day's use, both filters were mostly plugged,” he says.

“Filters should be cleaned once a day!”

Through his shop, he schedules machines to be serviced once a month, which includes changing oil and filters. “This does not save you the additional cost of fuel on a daily basis,” Schwinn explains. “Only by using the Air Filter Blaster can you get these huge savings.”

In fact, Schwinn has ordered Air Filter Blasters for all his clients.

Field-ready unit

The portable unit is designed to be taken directly into the field or on the road, either with a service truck or for dedicated use on a single piece of movable equipment.

The standard portable unit comes with the 6-inch rotor head and will clean filters up to 25 inches tall. An optional 3-inch rotor head is available and sold separately.

The Air Filter Blaster requires a compressor with 90 psi and retails for $349.

“This is probably one of the only tools you'll buy that will pay for itself the first day you have it,” says Grieve.
