A replacement muffler with a three-way catalytic converter built in. It bolts on in place of the stock muffler on propane, gasoline and natural gas engines and cuts the carbon monoxide, hydrocarbons and nitrogen oxides in the exhaust, which matters most on forklifts working inside warehouses, plants and cold storage.
Matched to the forklift or engine so it mounts like the original. Covers the common propane forklift engines: GM 2.4L and 4.3L, Nissan K21 and K25, Mitsubishi 4G6 series, PSI 2.4L and 4.3L, Kubota WG series, Toyota 4Y, and Ford and GM industrial V8s. Toyota, Hyster, Yale, Clark, CAT, Mitsubishi, Nissan, UniCarriers, Komatsu, Doosan, Linde and more.
For older engines without electronic fuel control: the catalytic muffler plus an oxygen sensor and an air/fuel ratio controller that keeps the engine at the mixture where the catalyst works best. Also fits propane floor scrubbers, burnishers, concrete saws, power trowels and generators.
The DOC is the first catalyst in a diesel exhaust. It cuts carbon monoxide, hydrocarbons and the soluble part of the soot. When it plugs or the coating is spent, the engine loses power and the controller may derate.
A particulate filter traps soot and burns it off during regeneration, but the ash left behind builds up until the filter restricts the engine. A plugged filter is cleaned, not rebuilt, and cleaning costs a fraction of a new one.
Air cleaning with a flow test for soot-loaded filters, and thermal cleaning for ash-loaded filters. Pickups and chip trucks (Ford, Ram, GM, Isuzu, Hino, Freightliner), buses, and Tier 4 chippers, skid steers, excavators and loaders. Drop off by appointment in Foxboro, MA, or ship it in. Fleet pickup available.
New filters for on-road trucks and off-road equipment when the substrate is cracked or melted, plus the gaskets, clamps and sensors that go back on with them.
Selective catalytic reduction uses diesel exhaust fluid and a catalyst to cut nitrogen oxides. We supply SCR packages sized to the engine for standby and prime power generators and for off-road diesel equipment, with the dosing hardware and controls, and replacement SCR catalysts for Tier 4 machines.
Noise and exhaust products that fit the same engines: generator silencers in industrial, residential and critical grades, catalytic silencers that combine a muffler with a catalyst, and direct-fit replacement mufflers for forklifts and compact equipment.
Wood chippers, stump and horizontal grinders, forestry mulchers, chip trucks.
Propane, gas and diesel forklifts, container handlers, burden carriers, floor scrubbers.
Skid steers, track loaders, mini excavators, compact tractors, boom and scissor lifts.
Standby and prime generator sets, light towers, pumps.
Diesel pickups, chip trucks, box trucks, buses and medium-duty fleets.
Concrete saws, power trowels, mowers, pressure washers and other propane or gas engines.
