Triangle stocks filters for locomotive filters, heavy duty, oil filters, air filters, fuel filters, cabin air filters, hydraulic filters, coolant filters and transmission filters. We can fill any order from 2-10,000 parts, each will meet or exceed manufactures spec’s.  Triangle will bid on all your heavy duty filter needs.  Filters can be delivered from local delivery in Chicago to national delivery within 1-2 days.  Our filters are an exact match to the OEM filters, exact fit, exact performance, but offer a less expensive option.

Off-highway heavy-duty construction engines add another element to the equation as they demand even greater filter performance in efficiency, capacity and structural integrity in order to combat their harsh working environment.

New innovations in filtration, including new forms of synthetic/cellulose filtration media, vastly improve particulate retention efficiency without sacrificing filter capacity. This is significant, as it is critical that heavy-duty filters remove as much contaminant as possible without restricting the flow of lubricants, air or fuel to vital engine components. Compared with traditional organic cellulose media types, engineers can more easily customize the performance characteristics of the new synthetic media to provide the best flow vs. restriction profiles, efficiency capability, and contaminant holding capacities.

Locomotive Filters

Greater media surface area, filters can trap more contaminants while maintaining low air flow restriction for efficient engine performance. Pairing premium filters with cleaner burning fuels and high-quality lubricants that contain fewer contaminants can exponentially increase both engine performance and the time between necessary lubricant and filter changes.

When compared with the cost of lost productivity, engine overhauls or new vehicles, paying a little more for the innovations inside premium filters is low-cost insurance that pays great dividends. Call us first for your, locomotive filters, and all your off road filter needs.
