The GreenVac portable vacuum system from Oakley Vac, a Division of WMW, has a lightweight and compact design allowing it be lifted by a single hook at the top of the unit. It’s easily loaded into a pickup or ATV trailer or airlifted into remote areas inaccessible to standard equipment. The unit incorporates a powerful positive displacement blower with an environmentally friendly Tier 4 diesel engine and is available in a variety of sizes and configurations, including spark-safe versions with grounding reels and positive air shutdowns. Material is vacuumed into 45-gallon drums that can be exchanged quickly and easily, avoiding downtime. 800/663-1624; www.oakleyvac.com.
