TM-45MD, Tier 4 Final Configuration.

Express Blower, a manufacturer of large pneumatic blower equipment, received certification on its self-contained machines, as required by the EPA Tier 4 Final, European Union (EU) Stage IV and California Air Resources Board (CARB) emissions standards.

The Tier 4 Final EPA/EU/CARB standards are required for off-highway diesel engines rated between 130kW (174hp) and 560kW (750hp).

Express Blower’s impacted models are the TM-45MD, TM-45HD, TM-70MD, TM-70HD and the compact SKHD.

“These models are our high-volume, high-output machines built for more extreme conditions and materials,” said Carla Severe, Express Blower’s marketing manager. “Nearly two years ago, the goal was set to provide not only a product that met all emissions requirements but that would also provide customers with improved safety, performance and serviceability. This means that other components were given a thorough review to ensure that our customers and our equipment received the full benefit of this redesign.”

John Deere Power Systems will provide the new engine packages. The JD PowerTech PSS 6.8L engine powers the MD models, while the JD PowerTech PSS 9.0L engine powers the HD machines.

Each engine package is equipped with an integrated emissions control system configured with cooled exhaust gas recirculation, a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF), as well as a selective catalytic reduction (SCR) system. The DOC/DPF reduces particulate matter, while the cooled EGR and SCR system reduce nitrogen oxides.

Other improvements to the Tier 4 Final machines include a simplified control system for system stability, ease of operator training, an enhanced patent-pending hydraulic control system and the ability to update with new functions or capabilities while in the field by using a USB drive, Express Blower said.

The Express Blower self-contained units operate off their own diesel engines and can be trailer or truck mounted.
