Express Blower – a manufacturer of large pneumatic blower equipment for the erosion control, landscape and green roof industries – received certification on its self-contained machines as required by the Environmental Protection Agency (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 174hp and 750hp, and they reduce emissions by 90 percent, the company says.

The company models impacted 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,” says Carla Severe, Express Blower marketing manager. “Nearly two years ago, the goal was set to provide not only a product that met all emissions requirements but 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 (JD) Power Systems was chosen to provide the new engine packages, Express Blower says. The JD PowerTech PSS 6.8L engine powers the MD models, while the HD machines use the JD PowerTech PSS 9.0L engine. Each engine package is equipped with an Integrated Emissions Control system configured with cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC) and diesel particulate filter (DPF), as well as a selective catalytic reduction (SCR) system, the company adds. The DOC/DPF reduces particulate matter while cooled EGR and the SCR system reduce nitrogen oxides.

Other improvements to the Tier 4 Final EB machines include a simplified control system for system stability, ease of operator training and the ability to update with new functions or capabilities while in the field by simply using a USB drive, the company says. There is also an enhanced hydraulic control system that delivers more power where it is needed, as well as providing better reliability and serviceability.

According to the company, Blower power (cfm/psi) remains unchanged or improved on all models.

The Express Blower self-contained units operate off its own diesel engines and can be trailer- or truck-mounted, allowing customers greater flexibility in power sources. The nature of this model also allows for different power packages – MD (medium duty) and HD (heavy duty) – giving customers even more choices in order to meet their businesses’ specific needs and goals. Due to the required integration with a chassis, Express Blower’s current EB-60 and EB-45 product line already meets Tier 4 Final requirements.
