CARB has verified the Rypos' DPF/LETRUTM (Level 2 Plus) diesel particulate filter, which can be used to comply with the Low-Emission TRU (LETRU) In-Use Performance Standard on most trailer TRUs using 2003 and older model year engines. The Rypos DPF/LETRUTM consists of active flow-through filters made out of an electrically conductive sintered metal fiber medium. It is microprocessor controlled with a backpressure control system, an electrical control circuit, and a backpressure warning indicator. TRU owners should read about the specific conditions for which the DPF/LETRUTM has been approved in the Executive Order, below. Specific engine models and families that apply are listed in the attachment below.
